Summary
Predictors of visual outcomes after cataract surgery were identified. Phacoemulsification yielded better visual acuity and function than extracapsular cataract extraction (ECCE), especially for patients with poorer baseline vision.
Area of Science:
- Ophthalmology
- Clinical Research
- Surgical Outcomes
Background:
- Cataract surgery is a common procedure to restore vision.
- Understanding predictors of visual outcomes is crucial for patient management.
- Comparing different surgical techniques informs best practices.
Purpose of the Study:
- To identify predictors of visual acuity and function post-cataract surgery in Singapore.
- To compare visual outcomes between phacoemulsification and extracapsular cataract extraction (ECCE).
Main Methods:
- 460 cataract surgery patients in Singapore were assessed preoperatively and 3 months post-surgery.
- Visual acuity and visual function (VF-14) were measured.
- Patient and surgery-related factors were analyzed as predictors.
Main Results:
- 85.1% improved visual acuity and 77.6% improved visual function.
- Poorer baseline vision predicted greater improvement.
- Phacoemulsification resulted in superior visual acuity and function compared to ECCE.
Conclusions:
- No pre-existing eye disease and better baseline vision predict better outcomes.
- Phacoemulsification is associated with better final visual acuity and function.
- Factors like age, education, and absence of complications also influence outcomes.
