This systematic review and meta-analysis evaluated visual acuity outcomes and complications following cataract surgery in Nigeria, analyzing data from 16 studies involving 3631 eyes. The study found that only 75% achieved good best-corrected visual acuity at ≥6 weeks postoperatively, significantly below the WHO benchmark of >90%.
Key findings
- 80.0% of operated eyes had a preoperative visual acuity of <3/60.
- Good presenting visual acuity at ≥4 weeks ranged from 8% to 86%.
- 75% achieved good best-corrected visual acuity at ≥6 weeks postoperatively.
- The pooled prevalence of posterior capsular ruptures with vitreous loss was 4.0%.
Why it matters
Understanding the visual outcomes and complication rates of cataract surgery in Nigeria is crucial for identifying areas needing improvement in surgical techniques and postoperative care, ultimately enhancing patient outcomes.
