Abstract

Background: Cataracts is the major global causes of blindness and a vision-affecting disease of the eye. Cataract surgery is a curative and cost-effective intervention. The number of people who undergo cataract surgery has increased rapidly. Hence, this study was aimed to determine predictors and the time of recovery of cataract patients after cataract surgery by using Simi parametric models of survival analysis.

Methods: A retrospective cohort study was conducted from January/01/2015 and January/30/2019. STATA version14.0 statistical software was used for analysis. The Kaplan-Meier survival method and log-rank test curves were applied. Weibull regression was used and adjusted hazard ratio 95% CI with a value of p less than 0.05 was used to identify a significant association.

Results: Two hundred twenty three cataract patients were recovered from cataract, 72.6% (95% CI 69.8%-75.9%). The overall median survival time was 23 weeks (IQR = 16 to 35) with (95% CI, 21%-25%). aged between 16 and 30year (AHR = 1.20 CI; 1.07-2.36), age 31 to 45 (AHR = 1.24 CI; 1.08-1.54), urban dwellers (AHR = 1.59; 95% CI, 1.18-2.14), medium visual acuity (AHR = 4.14 CI; 2.57-6.67), high visual acuity (AHR = 5.23 CI; 3.06-8.93), Secondary cataract (AHR = 2.59 CI; 1.01-3.02), traumatic cataract (AHR = 1.75 CI; 1.01-3.02), extra capsular cataract extraction surgery (AHR = 1.43 CI; 1.07-1.94),and diabetes mellitus (AHR = 0.75, CI; 0.41-0.96) were notably associated with time to recovery.

Conclusion: Time to recovery in the study area was slightly higher as compared with the global cut of time. Cataract patients with comorbidity of DM had lower recovery time.
