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!

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.

My Intralasik Experience

I wanted to investigate Lasik vision correction for myself, and found that there were several options. After talking it over with a great Lasik physician, I decided on using bladeless Lasik, or Intralasik, or Intralase. I cannot say that I decided that for any great technical reasons, mine were mainly psychological.

The advantage of Intralasik over a traditional Lasik procedure is that a laser is used to make a flap in the eye. Every Lasik procedure needs to make a flap in order for the excimer laser to be able to reshape the corner. In traditional Lasik, the flap is made with a microkeratome, which is “a very small blade, not a scalpel”. Well, maybe to you. Somehow, even though both the laser and the blade made the same flap, the idea of someone taking a sharp object to….. well, you get the picture.

In addition (though there is a lot of argument and debate over this) using a laser to make the flap might (let me emphasize might to be fair to everyone) make the Lasik procedure have less chance of getting other cells underneath the flap. I don’t really understand all of the Lasik arguments with regard to this, but I think you should discuss the various Lasik options with the physician. They do vary in cost also.

Before I talk about the procedure itself, let me give a bird’s eye view of myself as a Lasik candidate. In short, spectacular! Seriously, all of the items for a good Lasik candidate could describe me: a healthy guy in my mid-thirties, with moderate nearsightedness and slight astigmatism, with good results on all eye exam tests (thick cornea, no eye scarring or infections, etc.).

I did visit two different Lasik surgeons to get their independent opinions of me as a candidate, and also their description of their services. One of the Lasik surgeons is on the staff at the medical college in a nearby major metropolitan center, so I was pretty assured that their opinions were valid.

On the day of the Lasik surgery I came in, paid my first payment for the procedure, and had my eye prescription rechecked. I was given post-procedure instructions on eye drops, no exercising (yeah!), and to go to sleep after the Lasik procedure. I was given a relaxant, and the Lasik physician and I went to the surgery suite.

The chair has padded pillows to rest and restrict head movement, and a teddy bear to hold if I wanted it. There was a clamp to hold my eyes open, and a suction ring, and then my vision in that eye went a bit dim. The first Lasik laser made the flap, and I focused on a small light while the other laser made the cornea changes. This took less than thirty seconds, or so I was told.

Mainly I was aware of clicking noises and some pressure, but no pain or real discomfort. After the eye flaps were put back in place, I rested in a recliner for about 20 minutes. I could see more clearly immediately after the Lasik operation was over, but was told not to try and test my eyes for a number of days, and rather concentrate on getting them healthy and healed.

I am surprised and immensely pleased it went so easily, well, and pain free. I would recommend this type of Lasik procedure to anyone.

Even a Chicken Can Get Lasik Surgery

If you take the time to read any of the message boards or chat rooms on the Internet about Lasik surgery, you will wonder how anyone could get the courage to schedule a Lasik procedure, and why on earth they would want it. The various Lasik clinics sound anywhere from impersonal to something similar to Dr. Frankenstein’s lab, and the Lasik procedure itself sounds, well, surreal. It seems like the only people that would get Lasik are those with such bad vision that they cannot get out of bed without their glasses on.

Well, let me give you my story of how I chose Lasik. First of all, my vision is not good, but not terrible either. I can actually go to movies and see well enough to enjoy the film without glasses, but I need glasses to drive in order to read the street signs far enough away to act on the information. So for me, Lasik was not necessary, but I figured would simplify my life. I am outdoors very frequently, backpacking, climbing hills, and mountain biking. Glasses do not last long with me, and I am frequently grinding into the dirt which is not the best situation for contact lenses. For these reasons, Lasik looked very appealing.

The paragraph above might make you think I am a “manly guy” (hope so, think so!), so why on earth would I be afraid of a little Lasik scalpel? OK, technically Lasik does NOT use a scalpel but rather a “microkeratome blade”, but it is still a sharp object approaching my eye as part of the Lasik procedure. Nowadays Lasik physicians can get a laser to cut the flap in the eye, which is more than a little better than a sharp blade. But anyway, I had too many spills in my life to think any sharp object nearing my eye was a good idea, even under the skilled hands of a Lasik physician.

After talking with three (yes, three!) independent Lasik physicians, they each assured me that a 28 year old guy in nearly perfect health (OK, I exaggerate a bit) with moderate nearsightedness was one of the very best candidates for a successful Lasik procedure. I decided to schedule my Lasik procedure with the one that had the best track record, and coincidentally took the most time to explain everything about Lasik to me.

The Lasik surgery was not painful, though I accepted nearly everything they offered to give me comfort, including a sedative and a teddy bear. (I even went back to take a picture of me and the Lasik comforting teddy bear.) The only strange thing I remember about the Lasik procedure itself was a smell, something vaguely like hair burning. I suppose that was my eye. I am kind of glad they didn’t tell me to expect that before the Lasik procedure, I am not sure I would have gone in.

After a few years, I guess I was a nearly perfect Lasik client, as my eyes now have 20/20 vision and have remained stable long after the Lasik operation. I say that if you are a good candidate for a Lasik vision correction procedure, grab that teddy bear and go on in.
