N2 - Purpose: To examine the outcomes of resident-performed manual small-incision cataract surgery (SICS) in an urban academic setting. Setting: Parkland Memorial Hospital, Dallas, Texas, USA. Design: Retrospective case series. Methods: Manual SICS was used only in selected cases for which phacoemulsification was expected to be difficult, namely for mature or brunescent cataracts, traumatic cataracts, and pseudoexfoliation syndrome or other causes of zonular weakness. All manual SICS cases performed by resident physicians as the primary surgeon over a 5-year period were reviewed. Postoperative visual acuity, intraoperative complications, and early postoperative complications were the main outcomes measured. Results: For the 52 cases identified, the mean preoperative visual acuity was 2.165 logarithm of the minimum angle of resolution (logMAR) ± 0.141 (SD) (95% confidence interval) (slightly better than had motion acuity), improving to 0.278 ± 0.131 logMAR (Snellen 20/38) corrected visual acuity postoperatively. Of the 52 cases, the most frequent intraoperative complications were iris prolapse (5 cases [9.6%]) and zonular dialysis (4 cases [7.7%]), with vitreous loss occurring in 1 case (1.9%). The most frequent postoperative complications were cystoid macular edema (3 cases [5.8%]), retained ophthalmic viscosurgical device (2 cases [3.8%]), intraocular lens displacement (2 cases [3.8%]), and microhyphema (2 cases [3.8%]). Conclusions: Although the more advanced wound construction in manual SICS might be challenging to surgeons unfamiliar with the technique, it was a safe and efficacious technique in the hands of learning residents. With several advantages over phacoemulsification, such as cost and ability to remove very dense nuclei, manual SICS will play a valuable role in modern cataract surgery.
