To evaluate the visual outcome and complication rate of manual small incision cataract surgery (MSICS) in hypermature morgagnian cataract (HMC). Aravind Eye Hospital, Pondicherry, India. Retrospective, single center study. Case records of patients diagnosed with HMC and who underwent MSICS from January to December 2019 were retrospectively collected. Data were analyzed for demographic details, preoperative risk factors, intraoperative/postoperative complications, and visual outcome at 1-month follow-up. 105 patients were included in the study. Preoperative risk factors like dense pseudoexfoliation were seen in 6 patients (5.7%), phacolytic glaucoma in 7 patients (6.7%), lens induced uveitis in 5 (4.7%), and phacodonesis in 30 patients (28.5%). Overall intraoperative complication rate was 14.3%, which included posterior capsular rent (n = 4), zonular dialysis (n = 7), and whole bag removal (n = 4). Due to poor posterior capsular bag support, 7 patients (6.6%) did not receive intraocular lens implantation in primary surgery. Both the intraoperative and postoperative complication rate were high in those with risk factors, and this difference was statistically significant ( P < .001 and .0005, respectively). On the first postoperative day, 70 patients (66.7%) had a corrected distance visual acuity (CDVA) better than 20/40, and at 1 month, 98 patients (93.3%) had a CDVA of 20/60 or better of which 89.5% had CDVA of ≥20/40. MSICS for hypermature cataract is relatively safe and yields adequate visual outcome. Preoperative risk factors, in addition to hypermaturity, increase the complication rate.

D007908 Lens, Crystalline A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION. Eye Lens,Lens, Eye,Crystalline Lens

They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery. Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D002386 Cataract Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
