Opting for the right LASIK surgery to correct your vision today is not the same as it was a decade ago. This is comparatively a recent medical breakthrough. It was only in 1994 that the first eye surgery was performed. Back then surgeons didn't have much option on how to go about the entire procedure. All they had was a microkeratome, a small mechanical blade which helped to create a flap on the cornea. Once the flap was created, conventional excimer laser was used for reshaping the tissue underneath.
That would allow the cornea to focus light directly on the retina exactly as it happens in a normal eye. This is all the option that an optometrist had about a decade ago. Since the this surgery has gone through a sea change and amazing advancements have been made in the technology that is being used. Lasers have become much smoother and precise which has allowed patients to have better vision than they could have ever imagined before.
One of the newest addition to this opertation technology is the machine called Intralase. This machine makes the metal blade redundant during a operation. Here flap creation is also done with the help of laser. So with the help of Intralase one can actually complete the entire surgery only using lasers. This makes the operation an all-laser surgery .
The greatest USP of Intralase is that it significantly reduces the risks of flap complications. When one is using the microkeratome to create the flap on the cornea there are risks of complications. These would include a flap being cut too thin, that the flap can tear, or may be it will not cut completely. Once you start using Intralase, such possibilities are almost done away with.
As the level of accuracy increases with the use of Intralase, the cases of re-operation also drop. That way it is a much safer option compared to microkeratome. But it must be understood that Intralase is not completely risk free. Flap related wrinkles and other similar problems are still a possibility eve with Intralase around. But it is also true that Intralase will bring down the actual cases of complications.
There are detractors to Intralase whose man line of argument would be that it is too new a method to jump to conclusions and that there is no substantial evidence that prior risks are negated. Also Intralase increases the length of an operation thereby increasing the opportunity for other complications to be introduced.
