Value Proposition

Cataracts are the leading cause of blindness in the United States. During cataract surgery, the cataractous lens is removed and replaced with an artificial lens. The cataractous lens is disintegrated using ultrasound, and particles must be vacuumed away from the eye with a tool that aspirates and irrigates the eye. In addition to vacuuming the loose lens particles, the physician must polish the capsule to remove residual bits of fibrous tissue that remain from the old lens.

Wake Forest School of Medicine's novel handpiece tip allows surgeons to accomplish these tasks with a single, multipurpose tool. With the advent of laser cataract surgery, this invention has significant potential to eliminate the ultrasonic dismantling of the cloudy lens.

Invention Summary

Wake Forest School of Medicine has created a unique multipurpose aspiration and irrigation handpiece tip for use in cataract surgery. The device features a texturizing area that allows for enhanced capsule polishing capabilities. It also provides the surgeon with an ideal amount of control and accessibility, presenting a convenient option in which polishing of an eye capsule concurrently with the irrigation and removal of disintegrated tissue may be achieved.
