Incisional Corneal Procedures
Since the late 1920s ophthalmologists have recognized that non-perforating incisions in the cornea can improve vision by flattening the cornea. This effect was used in RK, the original refractive procedure for myopia. Although RK has been largely abandoned in favor of LASIK, short corneal incisions called astigmatic keratotomies (AKs) are still used to reduce astigmatism during cataract surgery or following corneal transplants. When indicated, AKs can be a cost effective, simple technique to reduce astigmatism and improve vision. Researchers at Bascom Palmer are currently investigating using the IntraLase infrared laser to create precise anti-astigmatism corneal incisions.
