Sight restoration rate (SRR): Useful indicator to measure impact of cataract surgery

Abstract

Untreated cataracts can reduce the productivity of patients and his/her caretaker for quite a long time. Cataract surgery will not only cure the patient’s blindness, but it will also improve the local economy if it is sustainable and on time. With advent of superior technologies cataract surgery performed in urban areas may target patients with vision more than 6/18 vision which in turn may not be sight restoration surgery, though number of surgery is more but sight restoring rate may be less so we need to use this indicator to determine actual impact. Lack of human resources, funds, and medical equipment are the major problems for performing cataract surgery.
