Innovative intraocular lens design to manage surgical aphakia in an eye with a filtering bleb

An innovative intraocular lens (IOL), the CM-T Flex IOL, was used to correct surgical aphakia without disturbing a functioning filtering bleb. A 66-year-old man presented with aphakia in the left eye. Cataract extraction and trabeculectomy was performed in the left eye 2 years previously elsewhere. Corrected distance visual acuity (CDVA) in the left eye was 6/18, and, on examination, it showed a filtering bleb that encroached on the limbus and superior cornea. The cornea was clear with a deep anterior chamber. Retinal examination was normal. Disc cupping was noted with a cup-to-disc ratio of 0.8. Refractive correction was performed by implanting the CM-T Flex IOL. This IOL has a unique design that eliminates the need for maneuvering the IOL haptics extraocularly. It entails a simple grasp, exteriorize, and release technique that anchors the IOL firmly to the scleral bed. At 6 months, CDVA in the left eye was 6/9 with a stable, centered IOL.
