Ultrasonic vibration that shatters and removes a lens clouded by a cataract describes which technique?

• A. Phacoemulsification
• B. Intraocular lens (IOL)
• C. Convex lenses
• D. Concave lenses

Answer: (A)

Phacoemulsification is the cataract surgery method that uses ultrasonic energy to emulsify the clouded lens into tiny fragments, which are then aspirated out and replaced with an artificial intraocular lens. This approach uses a small incision and minimizes tissue disruption, allowing rapid recovery. The implanted intraocular lens is what stays in the eye after the lens material is removed, but the technique for breaking up and removing the cataract is phacoemulsification. The other terms refer to an implanted lens or lens shapes used for vision correction, not the method of removing the cloudy lens.
