Glauco-Claw: A novice implant for chronic angle-closure glaucoma

This article describes 1-year outcomes of a new intra-ocular implant, "Glauco-Claw," in refractory chronic angle-closure glaucoma (ACG). Glauco-Claw is a novice polymethylmethacrylate implant with a central ring and five claws placed circumferentially. It was placed in the anterior chamber and the peripheral iris was tucked into the claws, thus causing goniosynechialysis and preventing the reformation of goniosynechiae. It was implanted in five eyes of five patients, and they were followed up for 1 year. Target intra-ocular pressure was achieved and maintained in all the patients till the last follow-up. Two patients did not require any anti-glaucoma medication. No significant complications were observed in any patient. Glauco-Claw could be another armamentarium in the management of refractory chronic ACG.
