Objective/Purpose: To describe the demographic and baseline ocular characteristics, prevalence of blindness and visual impairment among patients undergoing extracapsular cataract extraction for age related cataract at the study hospital over a one year period. Materials/Patients: All consecutive patients aged 40 years and above identified with age related cataract in one or both eyes who voluntarily agree to participate were included. Methods: The study adhered to the tenets of the Helsinki declaration. Written informed consent was obtained from all eligible patients. All patients underwent basic eye examination by the ophthalmologist. Visual impairment was determined for each eye according to the standard WHO categorizations. Information obtained also included age, sex and history of previous cataract surgery. Data were recorded in manual tally sheets and on modified computer Cataract Surgery Record forms. Analyses were done using SPSS (version 16, SPSS Inc., Chicago, USA). Results: The participation rate was 91.2%. There were 495 eyes of 487 consecutive patients. This include 212 males and 275 females (M:F, 1:1.3). The age range was 40 to 99 years with a mean age of 62.76 ± 10.49 years (61.35 ± 9.75 years in men and 63.85±10.9 years in females). Most of the patients (n = 451; 92.6%, 95% CI: 89.9-94.6%) were aged 50 years and above. Sixty patients (12.3%, 95% CI: 9.6-15.5%) had cataract in both eyes, 427 (87.7%, 95% CI: 84.5-90.3%) were in one eye. Among these, preoperatively 16 (3.3%, 95% CI: 2.0-5.3%) had aphakia, 21 (4.3%, 95% CI: 2.8-6.5%) had uniocular pseudophakia. About 63.2% (95% CI: 58.9-67.4%) of patients had normal vision in the better eye (presenting VA ≥6/18). Overall 9.5% (95% CI: 7.3-12.7%) were bilaterally blind. About 96.8% of eyes (95% CI: 94.5-98.0%) undergoing cataract surgery were blind (presenting VA<3/60). Conclusion: The study highlights preponderance of females and high incidence of blinding cataract. Education and early disease awareness may play an important role in these patients and could improve cataract surgical services in our hospital..
