New contact lens enhances pediatric vitreoretinal surgery
NEW ORLEANS — A new large diameter, two-piece contact lens enhances visualization in performing pediatric vitreoretinal surgery, according to researchers here.
According to Gholam A. Peyman, MD, and colleagues with Tulane University, the lens has a 13.6 mm diameter and a 7 mm contact diameter. This smaller size “sacrifices only the more tilt-sensitive parts of the optics and laboratory measurements in a model eye showed a 61· binocular field of view, a 94· static field of view and a maximum 129· field of view,” Dr. Peyman wrote.
No complications were noted with lens use in 10 cases (eight with retinopathy of prematurity, two with traumatic eye injury).
The study was published in the February issue of American Journal of Ophthalmology.
