A Novel Tip for Cataract Surgery

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 surgeon currently must polish the capsule with a separate tool to remove residual bits of fibrous tissue that remain from the old lens.

Wake Forest’s new multipurpose aspiration-irrigation tip for cataract surgery is a single tool that does not rely on ultrasonic vibration and which simultaneously helps to remove a cataractous lens and to polish the eye capsule.

Invention Summary

The multipurpose aspiration-irrigation tip is a single hand-piece that simultaneously irrigates and removes disintegrated tissue and polishes a posterior capsule. This tool is designed to be used following a femtosecond laser procedure to remove the residual cortical material and to polish the capsule. The device features a texturizing component that allows for detailed capsule polishing capabilities, and its design provides the surgeon with a high level of control and accessibility.

Benefits

  • The multipurpose aspiration-irrigation tip provides the surgeon with a single, multipurpose tool for cataract surgery.
  • The texturized surface of the tool allows for detailed capsule polishing capabilities.
  • The device is designed to be inexpensive and easy to produce.
