What Is True About Intra Lasik

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.

Statistics For Lasik Surgery Patients

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.

My Day For Lasik Surgery

My Day for Lasik Surgery

This story is for my family and friends who wonder what it is like to go through a Lasik vision correction procedure. I’ve shared my experiences with one or two colleagues at work that have also had Lasik done, and there are enough variations to give insight to those who are trying to choose between different Lasik physicians or different Lasik centers.

First, my Lasik procedure was scheduled for 4 PM in the afternoon, which was fine with me. One of the directions for patient that has just had a Lasik procedure was to go to sleep as soon as possible, in order for the healing process to begin as quickly as possible. And usually by the end of the afternoon I am too tired after working all day to be very nervous. Well, usually anyway.

I had only been there a few minutes when I was called into a room to prepare me for the Lasik procedure, and to get instructions (again!) on how to care for my eyes once the Lasik vision correction has been done. They offered me some Ativan, which is a mild sedative just to keep me calm during the Lasik process. The lasers themselves monitor any head or eye movement and turn themselves off when it occurs, so it isn’t that the sedative is for anything other than psychological reasons. I took it anyway. All of my colleagues at work also took it, though none of us really felt any different than we did before. Apparently it is a VERY mild sedative.

My eyes were prepared for the Lasik procedure by being dosed with eye numbing drops and some kind of medication. I cannot be sure of the other pre-operative steps, as I think I was trying very hard not to think about either Lasik or my eyes. Perhaps the sedative was a bit stronger than I imagined it was.

At this point I was escorted into another room for some time, where I sat back, listened to the piped-in music, and awaited my turn in the Lasik operating room. There were two other people waiting with me in this room, so apparently my doctor different setup for his Lasik patients than my colleagues. Both were alone in their pre-op rooms until they were escorted into the room where the Lasik procedure was actually performed.

As to the Lasik procedure itself, all of us have similar memories from this procedure. Each of us felt some pressure when the various Lasik implements were used on our eyes, though there wasn’t any real discomfort or pain. There was a blurring of vision for the eye being worked on, but the real sensation was mainly audio – the whirring and clicks of the machine. One of my colleagues also remembers a distinct smell, somewhat reminiscent of hair burning. There may have been a slight smell during my Lasik procedure, but it wasn’t significant enough for my attention to be focused on it.

After a short amount of time, my Lasik physician said he was done and that I had been a good patient. In all of our Lasik experiences, the operation itself was much easier than all of our worries about it beforehand. I hope this helps those of you considering having a Lasik procedure done.
