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.
Market Need for this New Cataract Surgery Handpiece Tip
Cataracts are the leading cause of blindness in the United States. According to the National Eye Institute, by age 80, more than half of Americans have had a cataract or cataract surgery, resulting in 1.35 million cataract procedures annually. 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 using 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. With the advent of laser cataract surgery, this invention may eliminate the ultrasonic dismantling of the cloudy lens. Wake Forest School of Medicine’s novel handpiece tip allows surgeons to accomplish these tasks with a single, multipurpose tool.
