Abstract
Visual improvement after cataract surgery in one eye diminishes the incentive for second-eye cataract surgery (SECS). This observational study aimed to determine if patients report for SECS with more advanced cataracts than for the first eye. Further, to explore the time gap between first-eye and SECS and factors influencing it. Adults requiring cataract surgery were included. Demographics, ocular and systemic conditions and peri-operative findings were compared between ‘First-eye cataract surgery’ and ‘SECS’ groups. Time elapsed since first-eye surgery and reasons thereof were analyzed in SECS group. Of 891 eyes operated, 376 (42.2%) were SECS. Frequency of advanced cataracts was comparable between the groups (p = 0.11), while ocular comorbidities was lower in SECS group (p < 0.05). Both groups encountered similar intra-operative (p = 0.72) and post-operative (p = 0.13) complications. Post-operative visual acuity was significantly better in SECS group (p = 0.007). Mean time interval between first-eye and SECS was 2.07 ± 1.8 years. A longer gap was associated with increased incidence of intra-operative complications (p = 0.04). Reasons for the time interval to SECS included “good vision in fellow eye”, “non-availability of caregiver” and “unsatisfactory outcomes with first-eye surgery”. Patients undergoing SECS did not have a higher incidence of advanced cataracts. Almost half the patients reported for SECS within 1 year. Experience of first-eye surgery influenced the decision to undergo SECS.
