It is the most common technique for cataract surgery.
Using ultrasound, the cataract is fragmented. A small 2.2-millimeter incision is made through which the opaque lens material is removed, and an intraocular lens of appropriate power is implanted to correct the associated refractive error. This is an outpatient, painless procedure performed under topical anesthesia.
Patient cooperation is necessary to follow the doctor’s instructions during the surgery. In cases where the patient cannot maintain steady gaze as directed, local anesthesia around the eye is also administered.
