Hydrogel polymer improves cataract surgery results at 24 hours

VIENNA, Austria — A hydrogel polymer applied to clear corneal cataract incisions at the end of surgery lessened corneal edema and resulted in better visual acuity at 24 hours, according to a study presented here.
John A. Hovanesian, MD, FACS, OSN Cornea/External Disease Board Member, presented results from a U.S. Food and Drug Administration phase 3 trial of the ReSure Ocular Bandage (Ocular Therapeutix) at the European Society of Cataract and Refractive Surgeons meeting.
"We've learned from cadaver studies of ReSure that this hydrogel bandage prevents ingress and egress of fluid from corneal wounds, which may have led in this study to a more stable IOP and formed anterior chamber after surgery," Dr. Hovanesian said. "This difference could quite possibly explain why eyes with ReSure had significantly better vision and less corneal edema."
In the prospective, randomized, multicenter study, 316 patients were treated with ReSure and 104 patients were treated with a Soft Shield Collagen Corneal Shield (Oasis Medical). At 24 hours the patients received a slit lamp exam and were evaluated for pain, best corrected visual acuity and IOP. The results showed a clinically significant improvement in best corrected visual acuity, equivalent pain and IOP measurements, and less observed corneal edema, Dr. Hovanesian said.
The ReSure Ocular Bandage has a CE mark and is commercially available in Europe.
