Summary
Cataract blindness is highly prevalent in Timor-Leste, with poor surgical coverage and outcomes. Improving cataract surgery services is crucial for the visually impaired population.
Area of Science:
- Ophthalmology
- Public Health
- Global Health
Background:
- Cataract remains a leading cause of blindness globally.
- Assessing cataract surgical services is vital for effective public health interventions.
Purpose of the Study:
- Determine the prevalence of visually significant and unoperated blinding cataract in Timor-Leste.
- Evaluate the coverage, characteristics, and outcomes of cataract surgery.
Main Methods:
- Population-based cross-sectional survey in 2005 using the WHO Rapid Assessment of Cataract Surgical Services protocol.
- Two-stage cluster random sampling of 1470 individuals aged 40+.
- Examination of eyes for visual acuity and history of cataract surgery.
Main Results:
- 11.5% of eyes examined were blind; cataract caused 66.3% of blindness.
- Cataract surgery coverage was low (16.3% for eyes, 20.2% for persons).
- Surgical outcomes were poor, with astigmatism and posterior capsule opacity as key issues.
Conclusions:
- An estimated 11,500 individuals are blind from cataract in Timor-Leste.
- Significant increase in indigenous cataract surgical service output is needed.
- Improved surgical outcomes and planning for laser capsulotomy are essential.
