A:Lasik is acosmetic surgery in which the cornea is thinned out to change the refractive error, before this procedure is performed the doctor will check your corneal thickness, your retina, and check your eye pressure. If your eye is fit than the surgeon will proceed with the surgery. Each laser machine has a software which calculates how much of the cornea is to be cut. zy optix is the software of the laser supplied by baush and loomb company which claims is takes in to account your corneal curvature so that you have less glare and contrast problems. Other companies also have launched similar softwares and call them customised lasik.
