While most of the time research centers on the latest technology, it is interesting to look back on through history to learn about the development of cataract extraction surgery.
Prior to the discovery of cataract extraction surgery, a procedure called couching was commonly performed. During this procedure, a sharp or blunt instrument would dislocate the cataract lens, pushing it back into the posterior chamber of the eye. The earliest documentation of this procedure dates back to the 6th century B.C. However, with with a much higher incidence of complications and greater risk of subsequent blindness this procedure is now antiquated since the discovery of cataract extraction surgery.
With the new lens in place, patients often remark about how bright, crisp and clear their vision is. Advances in lenses have allowed for patients to select from premium lenses, often furthering vision enhancement. Some patients who select such lenses may even find that they no longer need glasses after cataract surgery.
