It is important to adopt preventive measures for optic neuropathy after LASIK. Vitreoretinal stress is induced at the posterior vitreous base during a posterior vitreous detachment after LASIK. Macular diseases may be a relative contraindication to LASIK in: Patients with high myopia and lacquer cracks Patients with angioid streaks and traumatic choroidal ruptures Macular hole may develop in myopic eyes after LASIK or photorefractive keratectomy. LASIK may be associated with uveitis. LASIK may be a safe and efficient option for treating refractive errors in eyes with previous retinal detachment surgery. Cryopexy, laser retinopexy, pneumatic retinopexy, or vitrectomy without a scleral band tend not to change the shape or length of the globe and should be preferred to repair RRD. Prophylactic treatment of vitreoretinal pathology before LASIK does not guarantee the prevention of post-LASIK vitreoretinal complications. It is very important to inform patients LASIK only corrects the refractive aspect of myopia, and vitreoretinal complications after LASIK although infrequent may occur. Reasons for poor VA after surgery for RRD post-LASIK include delayed referral to a vitreoretinal specialist.
