LASER REFRACTIVE SURGERY
 

LASER REFRACTIVE SURGERY

Refractive surgery is the surgery to correct sight problems like short sight, long sight etc. in the past this was achieved with a knife and the dexterity of the individual surgeon. The procedure used to be called radial keratotomy (RK). The disadvantage with this procedure is that this can only be used for lower powers of myopia (short sight also) and there are permanent scars left on the cornea which could lead to glare etc. this is now replaced by lasers and is now laser refractive surgery. Once again the treatment is in the cornea. The major advantage to the refractive surgery is that it uses computer controlled laser instead of knife and mechanical devices like microkeratome instead of hanks. Therefore, the procedure is highly refined and the results are extraordinarily accurate, without scarring. More important we can have not only myopia but hyperopia and astigmatism.

What is cornea?

Cornea is the transparent structure in the front of the dark part of the eye. Its very much like the watch glass. If you notice the watch the color i.e.., the black or white dial comes from behind. But in reality there is a protective glass in front. Similarly in the dark part of the eye, the color comes from behind and the transparent dome like structure in the front is the cornea. Any kind of refractive surgery is generally done on the cornea. The central thickness of the cornea is normally above 500µ and if it is below this no refractive surgery should be done. Under the work laser refractive surgery we at Maxivision offer 4 different kinds of procedure. PRK, Zyoptix-PRK, Lasik, Zyoptix-Lasik.

What if you are not suitable for laser refractive surgery?

This is when we offer Phakic IOLs and Bioptic procedure.
