It wasn’t that long ago that patients who underwent surgery to remove cataracts were left with partial vision or very thick eyeglasses. Then, about a generation ago, intraocular lens transplants began. Since that time, questions have arisen about the risk of human lens transplants, specifically if the lenses would eventually dislodge. Researchers at Mayo Clinic set out to find the answer.
The team, led by ophthalmologist Jay Erie, M.D., scoured decades worth of medical archives known as the Rochester Epidemiology Project. They identified over 14,000 cases of cataract extraction in more than 9,500 residents of Olmsted County, Minnesota. Of those, only 16 cases involved late posterior chamber dislocation of intraocular lenses. Based on their data, the team calculated the risk of dislocation at 5, 10, 15, 20 and 25 years and found it to be less the one percent in all cases except 25 years, when it rose to 1.7 percent. A risk Dr. Erie characterizes as extremely low.
Coauthors on the study were Sam Pueringer and David Hodge, of Mayo Clinic. Their findings were published recently in the American Journal of Ophthalmology. The study was supported in part by Research to Prevent Blindness, Inc., and a Robert R. Waller Career Development Award from Mayo Clinic.
