When I consider how far we’ve come in cataract surgery today, in all candor, I think more important than foldable IOLs—perhaps even more important than phaco—is the advent of the OVD. When I started implanting lenses, we did not have OVDs at all. We could not implant successfully in a number of patients without actually extracting vitreous. We would take a 22-gauge needle, pierce it through the pars plana, and aspirate vitreous in order to make room to implant a lens. As a result, the complication rates were a concern, and very few surgeons could accomplish lens implantation in a significant percentage of their patients. ... Read More
Originally, vibration used to remove cataracts was not based on ultrasound energy. Charles Kelman at one time removed lenses via small incisions, a collapsible “butterfly net” made of thin latex, and manual head vibration, according to the book Phacoemulsification Surgery by Rasik B. Vajpayee, M.D.
Using that technique, the pupil was dilated, a special enzyme loosened the zonules, and the patient was turned over on his face. His head was vibrated manually until the lens fell into the anterior chamber. Eventually the latex net was introduced to trap the cataract, which was mashed with a needle. The net and crumbled cataract were then pulled through the small incision, Dr. Vajpayee noted.
