History of eyes and cataract surgery

-

 The first reported surgical removal of a cataract from the eye occurred in Paris in 1748. The advent of topical anesthesia made this procedure more practical. The early techniques involved removing the entire opaque lens in one piece using an incision that went halfway around the circumference of the cornea.


During cataract surgery, a patient's cloudy natural cataract lens is removed, either by emulsification in place or by cutting it out. An artificial intraocular lens (IOL) is implanted in its place. Cataract surgery is generally performed by an ophthalmologist in an ambulatory setting at a surgical center or hospital rather than an inpatient setting. Either topical, sub-tenon, peribulbar, or retrobulbar local anesthesia is used, usually causing little or no discomfort to the patient.
