Kamra corneal inlays can improve visual acuity in presbyopic patients who have previously undergone refractive surgery, a recent retrospective chart review shows. At the 2018 annual American Society of Cataract and Refractive Surgery meeting, Shamik Bafna, MD, of Cleveland Eye Clinic, presented his research on the topic. After reviewing charts for 108 patients who had undergone refractive surgery and subsequently had the Kamra inlay implanted, Dr. Bafna found that uncorrected near visual acuity (UNVA) had improved by approximately four lines in the first month after surgery, and uncorrected distance visual acuity (UDVA) had improved by approximately one line.
Results also continued to improve over two years. While 95% of patients showed stable UNVA of 20/40 or better after the first month, the 60% with 20/25 or better improved to 70% by the two-year mark. On the distance front, 75% of patients had UDVA of 20/40 or better at one-month post surgery and 90% achieved that acuity at two years. Meanwhile, patients with UDVA of 20/25 improved from 35% at one month to 70% at two years.
The Kamra inlay was recently acquired by SightLife Surgical. The company rebranded itself under the name CorneaGen on April 12.
