Objective: To study evolution of cataract surgery (from ECCE to manual small incision cataract surgery to phaco-emulsification) in relation to ease of surgery and visual outcome in eye camps in northern India. Design: Cross-sectional study Materials and Methods: The study included 780 patients who underwent cataract surgery following screening of 4763 patients at community screening camps. Patients underwent ECCE (Extra-capsular cataract extraction), SICS (small‐incision cataract surgery) and phaco-emulsification with intraocular lens implantation under local anaesthesia at the base hospital. Patients were followed up on 1st day, 1st week, 6th week, 3rd month, and 6th month postoperatively. Postoperative complications and visual outcome were recorded. Main Outcome Measures: Visual outcome and complications in patients undergoing surgery Results: Among the 4763 patients seen in OPD, almost two-third of patients were between 41 to 70 years of age and approximately half (52.82%) of patients were females. Cataract (53.52%), refractive error (16.75%) and corneal scarring (8.34%) were among leading causes of ocular morbidity.Out off 780 patients selected for cataract surgery, most were between 40-60 years of age(82%) and 52.5% were females.82% of patients were from lower socio-economic class. Complication rate was more in ECCE with PCIOL group and less in Phaco-emulsification with PCIOL group. Best corrected visual acuity at 6 weeks follow up was better in SICS and phaco-emulsification group while average numbers of follow up visits were less in these two groups as compared to other two groups. Conclusion: Our study reflects the efficacy of the base hospital approach and also adopting newer surgical approaches at base camps gives easily visual rehabilitation, better visual outcomes and compliance, and lesser complications compared to older methods. Phacoemulsification and small incision cataract surgery are safer than conventional ECCE surgery.
