Time to Toss Those Reading Glasses?
April 6, 2001 -- After 48-year-old Cheryl Goodman had laser eye surgery two years ago, she was able to see without prescription glasses for the first time since the fifth grade.
But for Goodman and most others undergoing the procedure, successful laser surgery did not free her from corrective lenses. Instead, the Dallas-based airline employee traded in her bifocals for reading glasses.
"I really didn't realize how much I would come to depend on reading glasses after laser surgery," she tells WebMD. "I had a pair at work and two pairs at home -- one upstairs and one downstairs. I knew laser surgery wouldn't take care of the reading problem, but I was desperately hoping that something would come along that would."
Last May, Goodman became one of the first Americans to have a two-hour surgical procedure designed to free her once and for all from reading glasses -- although she had to travel to Mexico to do it. The technique is still in early-stage testing in the U.S., and it will be several years before the FDA decides whether to allow it to be performed routinely here.
If the procedure does win FDA approval, the market for it would be huge. That's because virtually everyone develops the condition known as presbyopia, characterized by a reduction in the eye's focusing power, sometime during their 40s. This leads to the need for reading glasses. There currently is no way to reverse the condition, and most people rely more and more on reading glasses as they age.
The presbyopia corrective surgery was developed by ophthalmologist Ron Schacher, MD, head of Presby Corp of Dallas. It is being performed on an experimental basis at a handful of centers in the U.S., under strict FDA guidelines.
Backers say preliminary results suggest the surgery also may be effective in treating two other eye conditions affecting people as they age: primary open angle glaucoma -- a condition in which the pressure inside the eye is too high, causing damage to the optic nerve, which leads to vision loss; and ocular hypertension, in which the eye pressure may be too high but no damage is being caused. This is sometimes a forerunner to glaucoma.
