ABSTRACT
Background. Worldwide, cataract is a major cause of blindness. The paper aims to evaluate factors associated with borderline and poor outcomes of cataract surgery at an Eastern Regional Health Authority (ERHA) hospital in Trinidad and Tobago. Materials and Methods. A hospital-based, retrospective study was done on 401 patients who had undergone cataract surgery (unilateral and bilateral) at an ERHA Hospital between March 2009 and September 2014. Data was collected on variables concerning demographic, medical history, surgical history, ocular findings and visual acuity (VA). The outcome variable of interest was Snellen's post-operative (presenting) VA which was transformed into a dichotomous variable with borderline and poor outcomes as one and good outcomes as the other. Data were analysed using univariate and multivariate logistic regression analyses. Results. Good outcome (presenting VA 6/18 or better) was seen in 350 (67%) eyes. The fitted model consisted of ocular co-morbidity (OR =2.133; 95% CI [1.346-3.380]), hypertension (OR = 0.520; 95% CI [0.381-0.928]), surgical procedure (OR = 1.56; 95% CI [1.004-2.425]), good preoperative VA (OR = 0.388, 95% CI [0.211-0.714]), borderline preoperative VA (OR = 0.485; 95% CI = [0.278-0.843]) and year of first visit to clinic (OR = 2.243; 95% CI [1.215-4.141]). Conclusion. There is a need for community-based outreach to increase awareness of eye health and diseases. It is recommended that the general population is encouraged to take responsibility for personal management. The facilities at the Hospital should also be enhanced.

Mentions: Comparison of visual acuity pre and post cataract surgery for data on 525 eyes of 401 patients is graphically presented in Fig. 1. Upon first visit to the clinic, preoperative VA showed that 114 eyes (22%) had good VA, 140 eyes (27%) had borderline VA and 271 eyes (51%) had poor VA. Post-operative cataract VA resulted in 350 eyes (67%) having good VA, 110 eyes (21%) borderline VA and 65 eyes (12%) poor VA. This shows that visual acuity improved in 326 eyes (62%), but worsened in 33 eyes (6%) with no change in 166 eyes (32%).
