Brief summary

The closure of corneal wounds during cataract surgery remains reliant upon sutures, self-sealing corneal incisions, or tissue adhesives. Each of these methods have disadvantages, including time-consuming procedures, distortion of the eye’s shape, increased risk of endophthalmitis, wound leaks, lack of mechanical strength and toxicity to the ocular surface. We have developed a thin, laser-activated chitosan adhesive film that can be rapidly applied to the eye for sutureless sealing of corneal wounds. In this study, we propose to demonstrate the safety and efficacy of our adhesive film-based technology, termed ‘Kleer-i’, in sealing corneal wounds for the treatment of corneal wound incisions created during cataract surgery. The film may allow for quicker surgery, rapid healing and prevent the risk of complications such as scarring, infection and wound leakage.

Interventions

Patients will undergo routine cataract surgery performed by Professor Stephanie Watson (Ophthalmologist). The Kleer-i adhesive film will then be applied over the main corneal wound incision by Dr Damien Le (Principal Investigator/Ophthalmology Registrar). The film will be irradiated by a laser for 45 seconds. This will only occur once at the end of the surgery. The procedure will be documented in the operation report.
