LASIK. The factors damaging surgery

  Cornea typically avaskuljarna, because it should be transparent to function usually. Its cells immerse oxygen from disrupture Membranula. Low water-permeable oxygen contact lenses reduce uptake of a cornea of oxygen which sometimes comes to an end with growth of blood vessels in a cornea, the process known as a corneal neovascularization. It can cause the soft augmentation of an inflammation both healing time and some discomfort during surgery because of the enlarged bleeding. Though some contact lenses, especially up-to-date RGP and the soft lenses of a hydrogel of silicone, become from materials with higher oxygen permeability, that the help reduces hazard of a corneal neovascularization, the patients figuring, that LASIK warn to avoid to outwear their lenses. Usually it is recommended, that contact lens use has been stopped some days or one weeks prior to procedure LASIK.

 2004 Wood University examination of the Trace has found, that effects LASIK cause warmth and humidity, both during procedure and for these two weeks before surgery.
