Abstract
Aims: The study aimed to assess the post-operative presenting visual acuity (PVA) and best-corrected visual acuity (BCVA) from six weeks and above post-surgery, of patients operated for age-related cataract with biometry-calculated IOL power and available IOL power implantation, in two hospitals in Jos, Nigeria.Study Design: Retrospective cross-sectional survey.Place and Duration of Study: Eye units of two mission Hospitals in Jos namely; Bingham University Teaching Hospital and the Faith Alive foundation Hospital, between June and August 2021.Methodology: Patients aged 40 years and above, who had undergone surgery for age-related cataract in the preceding 18 months in two hospitals in Jos and were six weeks or more post-surgery were consecutively enrolled into the study, after obtaining informed consent. Socio-demographic data and surgical history were obtained from patients and their surgical records. The PVA and BCVA were assessed and categorized based on World Health Organization guidelines. Results: A total of 87 patients were examined within the study period. Post-operative PVA was good (?6/18) in 32 (36.8%), borderline (<6/18-6/60) in 41 (47.1%) and poor (<6/60) in 14 (16.1%) participants. After refraction, the proportion of good outcomes increased to 78.2% with only 8.1% of outcomes remaining poor. Biometry-calculated IOL power and available IOL power use did not significantly influence visual outcome (P=.645 and P=.146 for PVA and BCVA respectively).Conclusion: Majority of participants had post-operative PVA in the borderline category with residual uncorrected refractive error as the principal cause. Regardless of the IOL power implanted, surgery for age-related cataract enhanced patients’ vision. This study has shown that the presence of biometry is a guarantee of refractive success. Hence, refractive outcome audits are essential.
