Vision gains maintained at 3 years after intracorneal inlay implantation

SAN FRANCISCO — Distance visual acuity and quality of vision results were maintained at 3 years in presbyopic patients who received an intracorneal inlay, according to a presenter here.
The prospective, nonrandomized clinical trial comprised 507 patients at 24 sites throughout U.S., Europe and Asia-Pacific who underwent pocket emmetropic implantation of the Kamra corneal inlay (AcuFocus) in the nondominant eye. Patients ranged in age from 45 to 60 years. All patients were followed for 36 months.
"On average, patients experienced a gain of 3.4 lines of uncorrected near visual acuity at 36 months in the inlay eye," John A. Vukich, MD, said at the American Society of Cataract and Refractive Surgery meeting. "Binocular contrast sensitivity was unaffected."
In the inlay eye, mean uncorrected distance visual acuity was 20/20, mean uncorrected near visual acuity was J2 and mean uncorrected intermediate visual acuity was 20/25. Mean binocular uncorrected distance visual acuity remained unchanged at 20/16.
Long-term data showed maintenance of visual gain, Vukich said, and patients were able to comfortably perform near and distance tasks without glasses in different lighting conditions.
"This is certainly a good substantiation with 3 years of follow-up and careful analysis, suggesting that these inlays do have a place and appear to be efficacious," he said.
