A technology created by University of Rochester physicians and scientists that has helped boost the eyesight of patients to unprecedented levels is now more widely available, thanks to approval by the U.S. Food and Drug Administration.
The technology, called the Rochester Nomogram, marks a leap forward for patients who receive refractive surgery, also broadly known as LASIK. Refractive surgeon Scott MacRae, M.D., helped develop the formula which has helped him achieve nearly unparalleled results in broad groups of patients.
With the aid of the Nomogram, a remarkable 99.3 percent of the eyes that MacRae operates on have vision of 20/20 or better. That's one of the best, if not the best, success rates among refractive surgeons in the world.
This week, a company that has licensed the technology from the University announced that the FDA has approved its use in its refractive surgery system. Technolas Perfect Vision is a cataract and refractive laser company that was formed through a joint venture of Bausch + Lomb and 20/10 Perfect Vision AG. It's currently the only company offering the Nomogram technology in its refractive surgery correction system.
The Nomogram was first created and tested at the University about five years ago by MacRae working together with Manoj Venkiteshwar, Ph.D., who was then a post-doctoral researcher at the University's Center for Visual Science.
MacRae, the director of the Refractive Surgery Center at the Flaum Eye Institute, had long noted that patients undergoing refractive surgery were much more likely to come out of the surgery slightly far-sighted, though their vision was nearly always 20/20 or better. He and Venkiteshwar studied the problem and created a complex formula that helps physicians understand more thoroughly how refractive surgery affects a person's eyesight. The Nomogram adjusts the way a laser interacts with a person's vision, vastly reducing the chances that the patient's e
