cataract extraction
Surgical removal of the natural lens of the eye that has become clouded by cataract formation. The procedure creates space for intraocular lens implantation.
Full Definition
A foundational ophthalmic surgical procedure involving the removal of the eye's natural crystalline lens when it becomes opaque due to cataract formation. The surgery is typically performed using ultrasonic energy to fragment the lens, followed by aspiration of the lens material. This procedure is almost always combined with intraocular lens implantation to restore vision. Modern techniques emphasize small-incision surgery to promote faster healing and reduced complications.
Usage
Usage note: Often used interchangeably with 'cataract surgery' but technically refers specifically to the lens removal component.
