What is True About Intra Lasik?

Now that Lasik vision correction surgery has been accepted for a number of years, there are several popular options for the procedure. One of these is IntraLasik, or Intralase, or bladeless Lasik. As the name implies, there is no cutting of the eye with a blade, instead the flap in the eye is made using a laser. Since bladeless Lasik is a newer procedure, there are a number of opinions around about how well this procedure works. Let’s look at several of these and determine which of these are true or false.

First, more Lasik clients get 20/20 vision or better using IntraLasik. Any Lasik procedure cannot guarantee perfect vision for every client, though more than 90% get results to at least 20/40 vision. However, it is true that the new techniques of IntraLasik do get even better statistics for giving clients clear vision.

Some are concerned that the laser that makes the corneal flap is standard, and cannot be tailored to each individual eye like can be done by the Lasik surgeon when using a blade. This is not true. The Lasik physician has control over the use of the laser for each individual in the same way that he can control the microkeratome blade.

IntraLasik can be used for both a standard and a custom Lasik procedure. This is true. Custom Lasik procedures using Wavefront technology (another somewhat recent advance in Lasik vision correction) can easily be used with a laser making the initial flap. This custom Lasik procedure, though more costly, is of great benefit for people with unusual eye shapes or problems.

Some have heard that using the laser is less accurate than the standard Lasik procedure. This is not true, since lasers can be controlled to micron level accuracy. This gives the Lasik physician extreme control to create exactly the flap needed for this particular individual eye: the precise size, shape, and depth for successful completion of the Lasik procedure.

Another common fallacy is that IntraLase has not been around long enough for trusted Lasik physicians to have confidence in it. On the contrary, many of the most honored Lasik physicians strongly endorse IntraLase due to the track record of very good results from the Lasik procedures. In addition, the quality of the machines and the precision that they give these Lasik physicians is very impressive. Many of the top flight Lasik doctors recommend this as a procedure of choice, assuming cost is not a significant variable in the decision of which Lasik procedure to use.

Similar to the objection above, some people think that Intralase is not a sufficiently test Lasik procedure option. On the contrary, more than one million of these procedures have been performed, and the impressive track record for this Lasik procedure has been discussed above. More and more Lasik physicians are trained in this option, and we will see many more such Lasik procedures in the future.

We hope that this discussion of bladeless Lasik has given more accurate information to those considering this Lasik technique. Please discuss this option with the professionals at your local Lasik center.

What is the Initial Lasik Eye Exam Like?

The first significant step before the Lasik surgery is to have a comprehensive eye examination, in order to be sure that you are a good candidate for the Lasik procedure. A map of your eye will be created during this exam. This map is used in order for the Lasik physician to determine how to reshape your eye to give you the clearest post-operative vision possible.

This eye exam will do several things. Your eyes will be dilated in order to see if there are any irregularities within the eye itself. The thickness of the cornea will be measured, and a precise map of the cornea will be generated. The “refractive error” (or the reason why your vision isn’t currently perfect) will be accurately analyzed in order for the Lasik procedure to get the best results possible. Finally, how your eyes generate tears will be closely looked at, as good tear production is essential for the health of every eye.

Before or after these measurements, the Lasik physician will discuss your past medical history to see any previous operations or any ongoing health problems. A few chronic conditions may make the Lasik procedure not a good option for some people, and also women currently expecting should wait for some time after delivery. The physician also will discuss the expectations the Lasik client has about the operation and subsequent changes in their lifestyle.

Though most people pass through this Lasik eye exam with flying colors, be prepared for some suggestions or serious discussion. Your eye map may indicate that a newer form of Lasik procedure might be better, such as one that generates a three dimensional waveform for each eye. Tear production issues may indicate that the Lasik procedure is not the best option for you, and the Lasik physician may recommend another solution.

If all goes well and the Lasik procedure is scheduled, the physician will review the treatment plan and what the client should do to prepare for the Lasik surgery. This plan may vary slightly between patients, but in general will look something like the schedule below. Always follow the recommendations of your Lasik physician closely.
First, contact lenses should be avoided for several weeks prior to Lasik vision correction, since contacts can slightly affect the shape of your cornea. It is important to let your eyes rest in order to get the most accurate Lasik vision improvement possible. Hard contacts should be avoided for a month, soft contacts for at least two weeks.

Stop using any lotions, makeup, or anything else that could possibly get into the eye the day or two before surgery. It is important to have your eyes as rested as possible before the Lasik operation. Also, arrange for someone else to drive you home after the Lasik procedure itself.

These are the most common steps to prepare you for an easy and successful Lasik procedure. Make sure you give the doctor all information needed for your case, and follow his directions closely. The Lasik procedure will give you a new outlook in life!

What is a Wavefront Lasik Procedure Like?

Let’s walk through what a client experiences when attending a Lasik center for a Wavefront Lasik procedure. The procedure itself generally only takes between five and ten minutes for each eye in total, and both eyes are done during the same procedure. The actual time to reshape the eye with the Lasik excimer laser is usually less than 15 seconds per eye.

Any person’s vision problems are generated by small “aberrations” within the eye that prevents the light from focusing objects as they should. The Lasik equipment locates and classifies these aberrations and then processes them so that the Lasik physician will correct these and allow the light to focus properly once the eye has healed.

In a Wavefront Lasik procedure, the patient stares at one point while a light is sent into the eye, which is reflected back and read by a Lasik Wavefront sensor. The distortions in this reflected light are mapped using a small computer within the Lasik system, and then this information is used to guide the laser that treats the eye.
Once the light creates the map for the eye, the Lasik surgeon has to create a small flap to access the cornea. This is done using a laser (this type of Lasik procedure is known as IntraLasik, or bladeless Lasik) or a small blade known as a microkeratome.

This flap is then opened to allow the cornea to be reshaped by the Lasik system.The excimer laser actually reshapes the cornea, which is the crucial part of the Lasik procedure. In order to determine exactly how to reshape it, the map created earlier by the Wavefront sensor is used to direct the beam of light accurately. The Lasik physician uses these precise tools to get the clearest vision results possible.

This custom Lasik procedure can not only correct such standard problems as nearsightedness, but can also address aberrations that create light halos, glare, haze, or starburst patterns. Once the Lasik physician determines that all relevant aberrations have been eliminated, he replaces the flap in its proper position, where it adheres normally and will heal naturally.

As mentioned earlier, this entire Lasik process takes between ten and fifteen minutes per eye. A patient gets a mild sedative and eye numbing drops to make the procedure both relaxing and painless. Most people notice an improvement in vision due to Lasik almost immediately.

Once the Lasik procedure is finished, you will get some eye drop medication to lubricate and protect your eyes. This medication (and the liquid in the drops themselves) may cause some blurring, and so for this reason (and to avoid any eyestrain) you should arrange for someone else to drive you home. It is also a good idea to go to sleep as soon as possible after the Lasik operation in order to promote even faster healing.

To promote optimal healing the Lasik physician often gives a plastic shield to wear over your eyes for the first night or two. Follow closely any recommendations by the Lasik physician. Do further investigation into this great new Lasik procedure, and get a clearer focus on your future!

What Happens After the Lasik Procedure?

After you are fully prepared, the Lasik procedure takes less than fifteen minutes to complete for both eyes. This will seem a remarkably short time to have a permanent change to your vision, and in this regard Lasik seems almost too good to be true. In addition, most Lasik patients notice improved vision immediately or within a few hours after the Lasik procedure has been performed.

This does not mean that you should expect to walk out of the Lasik clinic with perfect vision and without any need to treat your eyes carefully for the next several days. It also means that some Lasik patients will need more time to see the total results for the Lasik procedure, sometimes as much as six months for their vision to stabilize permanently. Anticipate good vision, and take the time and care for the operation to produce its best result.

Usually the Lasik physician will give the post-procedure patient a protective shield for their eyes. This should be worn as long as the physician specifies, and usually only at night for one or two nights. He may also recommend sunglasses during the day if you experience sensitivity to light after the Lasik procedure is done. Discuss these options in detail at the Lasik center before the operation, so you know how to best take care of your eyes.

Many patients at the Lasik centers often get eye drops to keep their eyes moist for some time after the Lasik procedure is done. Again, this varies by patient and by physician, so ask about your particular situation, especially if you are prone to eye dryness on an occasional basis even before the Lasik procedure. Also, it might be helpful to keep any ceiling fans or other air circulation devices off in the household for the first few days.

Most clients can return to work and normal daily activities the day after the Lasik procedure is done, and do not require any extra assistance from other friends or family members. There is usually little to no post-operative discomfort after Lasik has been performed. It is recommended that patients go to sleep as quickly as possible after the Lasik surgery in order to minimize any post-operative discomfort. Upon waking, improved vision from the Lasik corrections should already start to be visible.

This improved vision may not be the final product of the Lasik procedure. The improvement to nearsightedness after Lasik is usually quick and dramatic, though there may be some problems in reading easily for the first few days after the Lasik operation. This is perfectly normal, and should clear up before the week is out.
Patients that use Lasik to improve their farsightedness usually find a dramatic improvement the day after the Lasik surgery. It might be that there is a temporary blurring of objects in the distance, but this will resolve itself. If this condition remains for more than a few days, the Lasik physician can recommend and prescribe temporary glasses until vision is stabilized.

These are all typical post-operative recommends for a Lasik patient, in order to feel comfortable with what to expect after the Lasik procedure. As with any medical treatment, get all of your questions answered by the staff of your Lasik center for your individual case.

Thoughts From an Experienced Lasik Patient

I have noticed that more people I work with are talking about, or undergoing, the Lasik vision correction procedure. I don’t know really know why Lasik has suddenly become more popular in my company, but I do know that there are a number of rumors about Lasik that I am not sure are true. Let me just talk about my long term experience with Lasik.

It has been more than eight years since I had the Lasik procedure, so I was one of the early and brave pioneers! Perhaps I wasn’t that brave when considering Lasik, for my vision in each eye was worse than -9. Even now, Lasik physicians consider that a very strong case and do caution prospective clients that the Lasik process will likely improve their vision, but may not eliminate the total need for glasses.

The Lasik operation itself had mild pressure and some unusual feelings, but no real discomfort or pain. This is still true in modern Lasik procedures, and hopefully they are even better at keeping the client comfortable. I do notice that now Lasik physicians also give a mild sedative mainly for psychological reasons, which I think I would have appreciated back then.

Two or three days after the Lasik operation I was astounded to find I had VERY clear vision in each eye, at least 20/20. Considering my previous prescription, you can imagine how fervently I thanked my Lasik physician. However, I did also have temporary symptoms of considerable dryness in each eye (which was helped by eye drops), and also halos around lights at night.

A few months after the Lasik procedure I noticed my vision changing a bit, though very slightly. The best way I can describe it is that the crisp edges no longer looked exceedingly crisp, but each object still seemed to be in focus. At my one year Lasik correction anniversary my physician said that one eye was still at 20/20, but the other had changed slightly to 20/40. However, I was still a great statistic for the Lasik correction procedure, and we were both still happy with the results.

In the years between the original Lasik procedure and now, my vision is still 20/20 in one eye and 20/40 in the other. I do have a pair of glasses and one contact lens for that eye, but rarely bother with them unless I am doing something like watching a movie. My long track record after the Lasik procedure has given hope to a number of other people in my office. I do want to say though that I was over 35 when I had the operation, and my Lasik physician said that the stability of my eyes and my age were good indicators that the Lasik results would be long term.

I hope this encourages people with bad vision to talk to a local Lasik physician about scheduling a Lasik procedure. Find a physician that has a good track record, and one that you trust, and I hope that your long term Lasik results will be as good as mine!

Talking to Your Lasik Surgeon

For anyone considering a Lasik procedure to correct vision, it is crucial to find a physician that is reputable and caring. It is also very important that they are experienced and knowledgeable in the Lasik procedure, and that they have a track record of patients that are happy with the treatment they received and the results that they got.

This guide gives a number of basic questions that you should ask when deciding on which Lasik center and which doctor to select for your Lasik procedure. The comfort you have during the process, and even the results that you receive, may depend on getting good answers to these questions. It is important to realize that the answers to these questions will vary from physician to physician.

The first question to ask is “How many years have you been performing this type of Lasik surgery?” There are several variations of the Lasik procedure, and the doctor should have a track record of at least three years in doing Lasik procedures. This amount of time also allows the doctor to watch his patients and the long term success of their Lasik procedures.

Next, ask the physician for the number of Lasik procedures they have performed in the last two years. The physician should do the operation frequently enough that he is well versed in current procedures. Also, he should be successful enough that prospective Lasik patients feel comfortable in coming to the Lasik center. The physician should perform at least 500 Lasik surgeries in the last two years.

At this point, ask what percent of his clients that underwent Lasik surgery ended up with 20/40 vision or better. Notice that not all patients will achieve 20/20 vision, and that is acceptable. However, it is important that 90 percent of the patients get at least a 20/40 correction after the first Lasik procedure. Claims of much more than 90 percent might make him seem much better, but in this case ask for evidence that that number is true. There are some exceptional physicians out there, but also a few Lasik doctors that make unfounded claims. Asking the doctor what percentage of Lasik patients achieve 20/20 should run about 50 percent. Again, if the number is greatly higher, ask for evidence.

Finally, ask about post-Lasik complications. The percentage of patients that experience complications after 6 months is complete should be 3 percent or less. If the physician claims that complications are so rare that he doesn’t keep records, you should be very suspicious and ask for evidence, if any. No doctor is perfect. Similarly, when asked the percentage of patients that require an additional operation to achieve clear vision, the number should be less than 10 percent.

To wrap up the interview, ask the physician what types of Lasik procedures he recommends and practices, and under what circumstances he denied a Lasik procedure to a patient. Not all vision challenged people are good candidates for a Lasik operation, and the doctor should at least have a few examples of people he dissuaded from the operation.

Finally, ask about the cost of the operation and if financing plans are available through the Lasik center. A physician that is willing to sit down and discuss these questions is often a physician that will address any other medical issues that come up, and is a good prospect to perform your Lasik procedure.

Tales From the Lasik Waiting Room

As an experienced Lasik patient I thought I might give a glimpse into the worst part of the Lasik procedure… the waiting room. I have had a Lasik procedure twice, the second being a follow up since one of my eyes needed additional work after the healing procedure was complete. I was distinctly less nervous about the second procedure, and observed and talked to a number of the other Lasik clients that were waiting with me.

One was a young woman in her early twenties who talked incessantly trying to keep her mind off of any of the Lasik brochures and information on the table. She had been thoroughly oriented to both the Lasik operation and post-op procedures, but had brought along a few stuffed animals to keep her company during the operation. Most Lasik physicians recommend a minimum age of 18 due to sufficient maturity of the eye, but maybe waiting for some emotional maturity might be another factor. On the other hand, I wondered what I looked and sounded like waiting for my first Lasik operation.

Talking to a few of the other Lasik clients, I realized I was not the only one in for a second Lasik procedure. Two others were like me in that they did not get sufficient improvement in their vision to satisfy themselves or the Lasik surgeon. In all of our cases, our first Lasik procedure of several months earlier went well, and none of us were particularly nervous.

It did surprise me, considering that it was 6:30 AM, of the variety of clothing styles of the Lasik clients. Most of us, considering the hour and the rather frigid temperature of the Lasik operating room and the waiting room, were dressed in snug and warm sweat suits or other comfortable wear. One Lasik patient was dressed in formal business attire with full makeup.

This puzzled me for at least two reasons: any makeup, lotions, or other things that could get into the eye are forbidden for at least 24 hours before the surgery, and it is highly recommended to go home and sleep as quickly as possible after the Lasik procedure. The only thing I could figure out was that she wasn’t actually getting a Lasik procedure, but no one else is there at 6:30 AM. Her dominating and withering look made me decide that any pre-Lasik conversation with her was better left unsaid.

I was probably the fourth person escorted into a waiting room for a final discussion on Lasik post-op procedures, but I could not tell how long I had been waiting. I think they avoid clocks for a very good reason. The lady two seats down from me was calm enough about her Lasik procedure to go back to sleep while waiting, which seemed like an eminently sensible idea.

Each patient is offered a mild sedative before the Lasik procedure starts. It is mainly for psychological purposes, as my first Lasik experience was not painful at all. I did take it for my first experience, but my own Lasik history and the others I have heard in the waiting room make me think that I don’t need it. But I take it anyway, just in case.

I hope that this window into a Lasik waiting room helps give the attitude that for most people it is not a dreaded procedure, and for those of us that have had Lasik done, a rather uneventful one.

Statistics for Lasik Surgery Patients

The Lasik operation can be a wonderful, life-changing option for many people whose vision is less than perfect. There are several different types of Lasik operations now available, from the original and well documented procedure to Lasik procedures done with three dimensional wavefronts, or done entirely with lasers. Each of these variations of the Lasik procedure should be discussed with the physician that is to perform the operation.
Like any surgery, Lasik does have the potential for side effects.

Sometimes reading the horror stories of the outcomes of a Lasik procedure can deter people from seriously considering such a choice. It is also true that the vast numbers of people who have a successful, trouble-free Lasik surgery tend not to report a long and detailed story of their experience, unlike those that have experienced trouble afterward.

However, it is good to know what the possible side effects of the Lasik procedure are, and also the likelihood that one of these side effects will occur for a particular patient. Just like any medicine we take, each has a possible number of side effects, but we generally assume that the likelihood of a serious side effect is small, and we take the medicine anyway. This article will hopefully put concerns of the prospective Lasik patient into perspective so that they can calmly and thoughtfully ponder having a Lasik procedure done in the future.

More than one million Lasik procedures are done in the US every year, according to the FDA. This arm of the national government has accumulated the following statistics for the most common side effects of the Lasik procedure. These statistics will also vary by the physician performing the surgery, so make sure to get as much information on the prospective Lasik physician as possible.

After Lasik surgery, 1.7 percent of patients experience some glare or sensitivity to light after the operation. This varies by patient, but this sensitivity is especially noticeable when looking at a bright light, such as a streetlight when walking at night, or other strong light and dark contrast. Another light related side effect is a halo around a light, and this occurs in 3.5 percent of Lasik patients.

The new, corrected vision can be noticed quickly by some Lasik patients, in as little as a few hours after surgery. Most patients that have undergone the Lasik procedure find the change is permanent within a few days. In 2.6 percent of clients that have had a Lasik procedure done, there is persistent visual fluctuation within at least a part of their sphere of vision.

Finally, some patients do not get a fully corrected sphere of vision after their Lasik procedure. This happens with a small number of clients, and the FDA statistics are that only 3 percent of patients have this effect. In all or nearly all cases, the physician in charge will perform an additional Lasik procedure to improve this.

This detailing of the major permanent side effects of the Lasik procedure should put any personal horror stories into perspective. Notice that none of the percentages are above 3 percent, and this should bring comfort to most prospective Lasik clients. However, it should also motivate them to look carefully at the Lasik physician’s personal record.

Solving a Lasik Post Op Problem

I had Lasik vision correction surgery two years ago, and am quite glad I did. I think that my Lasik story might be helpful to some that consider that they might not be a perfect Lasik client, and are concerned about side effects after the Lasik procedure. I did have a significant side effect after my Lasik operation, but have weathered it well, and still recommend the operation highly.

My operation went exactly as described, with no pain or real discomfort at all. My Lasik physician was clear, stating each step that he completed so that I would know the Lasik procedure was proceeding as expected, and more quickly than I had imagined. I know that all of the discussion I had earlier with the Lasik professionals stated the operation generally took less than twenty minutes, but I was still surprised.

At the end of the operation, my Lasik doctor replaced the flap to its correct position in my eye and covered it with some kind of clear goop. Even at that time I could notice a distinct improvement in my vision. I was instructed to wear goggles over my eyes for five nights in order to prevent me rubbing my eyes while I was sleeping. I guess they assumed that any good Lasik patient would not do that when awake.

In addition, I followed all post-op Lasik procedure instruction to the letter. I slept immediately after the Lasik procedure was done (after I made it home, of course), used the eye drops religiously, and did not try to strain my eyes by reading everything that I could. I was amazed the immediate improvement in vision that Lasik makes, just as if there was a set of weightless contact lenses. Very impressive.

My biggest problem in Lasik procedure recovery was a result of epithelial erosion. The flap that is made in the eye during the Lasik procedure is made from epithelial cells. Once the flap is replaced at the end of the Lasik procedure, these cells start to regenerate in order to fill in the line where the flap has been cut. All of this is normal post-op Lasik healing. However, in my case the cells would grow fine, but at night my eyes tended to dry out when I was asleep. So, when I woke up, my eyelid would pull up some of the new cells from their place where they belonged, where if my eye was sufficiently moist they would have stayed in place.

I told this to my Lasik physician, who said this side effect just makes healing a little longer and it was not a serious side effect. When I went for a checkup to the Lasik center (which I highly recommend any time a Lasik client has any post-op worries or questions) they decided that I needed a thicker, more jelly like version of the eye drops to use at night. This worked well, and the rest of my post-Lasik recovery went well.
I am a strong advocate of the Lasik vision correction procedure. I also strongly suggest interviewing a number of positions, and do not put low cost as the highest priority. Your eyes are very important, and a highly competent Lasik physician is the most important factor.

Should I have Lasik or ICL?

A number of people who are considering the Lasik procedure to correct their nearsightedness or farsightedness have of some potential problems of Lasik, and are wondering if there are other options. Though more than 95 percent of the Lasik patients have a very successful procedure without any major side effects, there are choices for people who wish to improve their vision. Let’s compare two, and discuss these choices with a reputable ophthalmologist.

Traditional Lasik surgery uses a scalpel to create a small flap in the eye, and then a laser reshapes the eye in order to focus accurately. There are two more recent forms of Lasik, one that entirely uses a laser and does away with the scalpel. Another variation uses a three dimension waveform for people with unusual eye shapes, and both of these are worth discussing with your ophthalmologist.

Those people with very thin corneas or other issues that make Lasik not a good candidate for their particular case can consider implantable contact lens surgery. This is known as ICL in the eye surgeon’s lingo, and is a good alternative to Lasik to permanently correct vision. These lenses function in exactly the same way as removable lenses, except that they remain permanently in the eye. Like Lasik, they reshape the eye in order for it to focus accurately. The patient will not feel the lens once the operation has been performed.

Lasik and ICL are similar in several ways. Lasik can improve vision affected by nearsightedness and astigmatism, and ICL can improve these vision deficiencies also. Both Lasik and ICL also have some of the same risks, one of these being that the correction is not accurate after the first operation is done. Lasik is a much more frequently performed procedure, and less than 3 percent (according to the FDA) of these patients need to undergo additional surgery to further correct vision after the first Lasik procedure is done.

Like any operation, there is a chance of infection in either a Lasik procedure or an ICL operation. Good post-operative care by the patient will minimize this and regular checkups at the Lasik or eye care center will nearly always clear this up without further complication. In a small percentage of the cases, either Lasik or ICL patients may not achieve perfect vision and may need to continue to wear corrective eyewear, though usually not at the same strength as the original eyewear.

One advantage of ICL over Lasik is that ICL is a reversible procedure, where the implanted lens can be removed later if that becomes necessary. Lasik involves the reshaping of the cornea to bring objects accurately into focus, and is permanent. However, for a typical, healthy patient either Lasik or ICL will generally bring about the desired improvement in vision.

Lasik is generally a less invasive procedure, and this is reflected in the current cost of the operation. The current price for a Lasik procedure is between $500 and $2500 per eye, depending on the type of procedure and the presiding physician. A typical price for ICL is between $1500 and $3000 per eye. Do some investigation into the options offered, and select the eye procedure that is best for your personal case.
