Evaluation of visual outcome of cataract surgery in an Indian eye camp.
Aim-To evaluate the results of cataract surgery performed in a rural Indian eye camp.
Method-The pre-and postoperative visual acuities and surgical complications were recorded prospectively in 6383 eyes undergoing cataract extraction for age related cataract in rural eye camps held in northern India in 1993-4.
The best visual acuity and cause of poor outcome were recorded on 3908 eyes seen at 6 weeks'follow up.
Of 6383 operated eyes 94.8% had a visual acuity of less than 3160 preoperatively, and 41% of the procedures were performed on patients who were bilaterally blind (less than 3/60 better eye).
At discharge with standard aphakic spherical spectacles, 11.3% of eyes had an acuity of less than 6160 (poor outcome), and 25.9% had an acuity of 6118 or better.
At 6 weeks'follow up 3908 eyes were examined (61.2%), of which, with best correction, 4.3% had poor outcome (acuity of less than 6/60) and 79.9% obtained 6118 or better.
Pre-existing eye pathology was responsible for poor outcome in 3.0% of eyes and surgical complications in 1.3% of eyes, of which corneal decompensation was the major cause (0.5%). In 237 eyes which received an intraocular lens implantation (IOL) in the camp, the visual acuity at discharge was 6118 or better in 44.5% of eyes improving to 87.9% in the 157 eyes which were seen at 6 weeks'follow up.
Poor outcome (less than 6160) was seen in 5.7% of the eyes with an IOL at discharge improving to 1.9% at follow up. (...)
