Over the last 10 or 12 years lasik surgery has gained a kind of popularity that has seldom been witnessed in the history of surgery. A few things have led to such an astronomical rise in the popularity of this particular surgical procedure. First of all, the relative low risk associated with this operation. With success rate around 95% and the figure going up with each new innovation there are hardly any other operation which can rival it on its safety.
Moreover, the operation takes extremely little time to complete with each eye being operated in under 10 minutes. That is remarkable for any operation and it can only be achieved because much of the operation these days is computer guided. Not that the expertise of the surgeon doesn’t matter. It does, and very much so.
This surgery is a great way to deal with the problem of astigmatism. Now what is astigmatism. Astigmatism is where the patient has irregularities in his cornea which as a result distorts the image formed on the retina of the eye. That can actually rectify this problem and help the patient to live a normal life.
You would now be curious about how actually the lasik operation is performed. Here is a synopsis for you. First a mild anesthetic will be administered. Also eye drops are used to numb the eye and avoid pain during the operation. Though the operation is pain free there have been patients who have complained of discomfort. Once the eye is numb, a little device known as the microkeratome is attached to a suction ring placed on the eye. The microkeratome has a blade which cuts a thin flap on the surface of the cornea.
The doctor will next fold back the flap and expose the stroma which is basically a layer of tissue. The stroma is searched for debris and is then dried. Now the surgeon will ask you to focus on a fixed spot while he, with the aid of laser mends the corneal tissue according to results of pre-operation examination. Once through, the flap is put back to position and an eye patch is provided to allow it to heal.
This operation is also highly effective in other conditions related to the eye. These would include myopia and hyperopia. While the former doesn’t allow you to see things at a distance, the latter is exactly the opposite where you cannot read the newspaper without the reading glasses.

It was only towards the very end of the last decade that the excimer laser was approved by the FDA for lasik eye surgery. But within ten years there has been a whole host of companies which have jumped into the race for capturing the largest share of the very lucrative this eye surgery market. The good thing about it is that there are now companies which are ready to pump in the dollars to carry out research and bring in new advancements.
But as companies develop new models they also are more eager to push their models to the doctor and to a certain extent to the patients. This is most apparent on the internet. If anyone is considering a eye operation and thinks about reading up some literature about it on the internet, he or she is bound to be bombarded with ads by various companies trying to convince him or her that their product is the best in the market. How true are such claims? Not that much. Yes, each of the models would be different from the other in some respect, but the overall difference will at best be minor. Breakthrough innovations don’t happen everyday.
So are all surgery machines safe? Well, the ones approved by FDA are. You got to know which are the various types of surgery machines that have been approved by FDA. There’s a whole host of them. Of them three companies dominate a large part of the market. They are Alcon, Bausch & Lomb, and VISX. Another major player in the LASIK market is Nidek, but their Wavefront technology which helps the operation machine to ma the eye is yet to be approved by the FDA.
The main concern for most patients thinking about surgery is the 20/20 vision. Studies of different models of operations show that there are no significant differences between them. The accuracy they provide are almost similar in all the cases. So on that count all these types of lasers score the same.
Another big concern for patients undergoing this eye surgery is the quality of night vision. Some patients do complain about visual aberrations and night halos after going through a surgery. Recent studies conclude that the traditional Alcon and VISX are more effective than the new Wavefront technology causing lesser visual aberrations during night. It is also understood that of all the major players VISX performs the best when it comes to night vision.
