Both LASIK and PRK Have Been Approved by NASA for Space Flight. A New Study of the Effect of Spaceflight on a NASA Astronaut with PRK Laser Eye Surgery Confirms PRK Was Safe, Effective, and Well Tolerated in Space. In my previous blog, we looked at the effects of very high altitude on LASIK laser […]

Radial Keratotomy (RK) — An Older, Non-Laser Vision Correction Technique — Has Been Associated With Visual Problems at Extreme Altitudes. LASIK and PRK Laser Vision Correction, However, Appear to Perform Well at Extremely High Altitude. Mountaineers and other patients interested in mountain sports such as skiing or backpacking have asked me about the effects of […]

Many researchers have asked what causes nearsightedness. This new study says outdoor activity may lower the risk of developing nearsightedness in children. While LASIK laser eye surgery and PRK laser eye surgery are excellent methods to “cure” nearsightedness (myopia), reasearchers have long wondered what causes nearsightedness to develop in the first place. As with many […]

PRK and LASEK differ from LASIK in that the laser is applied to the surface of the cornea directly. PRK and LASEK use different approaches, yet a hybrid technique works best. PRK laser vision correction was first approved for use in the United States in 1995. While the techniques for performing PRK (photorefractive keratectomy) have […]
