A U.S. patent was granted to Gholam A. Peyman, MD, in June 1989 for a method of modifying the corneal curvature of the eye. The surgical procedure involved cutting a flap in the cornea, pulling the flap back to expose the corneal bed, ablating the exposed surface and then replacing the flap. The current procedure of laser assisted in-situ keratomileusis (LASIK) was not FDA approved until 1999.
The femtosecond laser has brought many significant advances to eye surgery. For more than a decade, it has been used to create lamellar corneal flaps for laser in situ keratomileusis (LASIK), and more recently this laser is used to precisely perform several steps in cataract surgery.
After much anticipation and a long wait for both clinicians and patients in need, the U.S. Food and Drug Administration (FDA) approved corneal cross-linking (CXL) in mid April. This procedure is globally considered the only method of halting the progressive family of diseases called corneal ectasias, including keratoconus.
One of the most common questions I hear every day from patients is, “What is new in refractive surgery?” I have asked Jim Owen, OD, an expert in refractive surgery technology, to discuss the latest version of LASIK—topography-guided LASIK—with David Geffen, OD, FAAO, who participated in Alcon’s Contoura Vision clinical trials.
A referral of your patient to a cataract surgeon seems straightforward. You refer when the vision is subjectively affected by lens opacification. But thinking out of the box will enable you to help your patients in ways you may not consider.
