Purpose: To evaluate cataract surgery visual outcomes and associated risk
factors in rural secondary level eye care centers of L V Prasad Eye
Institute (LVPEI), India. Methods: The Eye Health pyramid of LVPEI has a
network of rural secondary care centres (SCs) and attached vision centres
(VCs) that provide high quality comprehensive eye care with permanent
infrastructure to the most disadvantaged sections of society. The most
common procedure performed at SCs is cataract surgery. We audited the
outcome of a random sample of 2,049 cataract surgeries done from October
2009-March 2010 at eight rural SCs. All patients received a comprehensive
ophthalmic examination, both before and after surgery. The World Health
Organization recommended cataract surgical record was used for data entry.
Visual outcomes were measured at discharge, 1–3 weeks and 4–11 weeks
follow up visits. Poor outcome was defined as best corrected visual acuity
<6/18. Results: Mean age was 61.8 years (SD: 8.9 years) and 1,133
(55.3%) surgeries were performed on female patients. Pre-existing ocular
co-morbidity was present in 165 patients (8.1%). The most common procedure
was small incision cataract surgery (SICS) with intraocular lens (IOL)
implantation (91.8%). Intraoperative complications were seen in 29 eyes
(1.4%). At the 4–11 weeks follow-up visit, based on presenting visual
acuity (PVA), 61.8% had a good outcome and based on best-corrected visual
acuity (BCVA), 91.7% had a good outcome. Based on PVA and BCVA, those with
less than 6/60 were only 2.9% and 1.6% respectively. Using multivariable
analysis, poor visual outcomes were significantly higher in patients aged
≥70 (OR 4.63; 95% CI 1.61, 13.30), in females (OR 1.58; 95% CI 1.04,
2.41), those with preoperative comorbidities (odds ratio 4.68; 95% CI
2.90, 7.57), with intraoperative complications (OR 8.01; 95% CI 2.91,
22.04), eyes that underwent no IOL or anterior chamber-IOL (OR 12.63; 95%
CI 2.65, 60.25) and those undergoing extracapsular cataract extraction (OR
9.39; 95% CI 1.18, 74.78). Conclusions: This study demonstrates that
quality cataract surgeries can be achieved at rural SCs. The concept of
the LVPEI SCs can be applied to other developing countries, allowing rural
patients to attain better vision through cataract surgery. Despite
improvements in quality of cataract surgery, gender discrimination in
terms of outcome continues to be an issue and needs further investigation.
