Summary
Immediate sequential bilateral cataract surgery (ISBCS) showed no worse visual outcomes or increased complications compared to delayed sequential (DSBCS). Both methods achieved similar refractive error results, with no significant difference in vision quality between first and second eyes.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Comparative Effectiveness
Background:
- Bilateral cataract surgery can be performed immediately sequential (ISBCS) or delayed sequential (DSBCS).
- Understanding the comparative effectiveness of these approaches is crucial for patient outcomes and surgical planning.
- Previous studies have explored visual acuity and refractive error differences, but comprehensive comparative analyses are ongoing.
Purpose of the Study:
- To compare best-corrected visual acuity (BCVA) and refractive error (RE) between ISBCS and DSBCS.
- To determine if second-eye outcomes in DSBCS differ from first-eye outcomes.
- To assess if ISBCS is associated with increased risks compared to DSBCS.
Main Methods:
- Retrospective comparative-effectiveness study.
- Intention-to-treat analysis of 13,711 DSBCS and 3,561 ISBCS patients.
- Conditional logistic regression accounting for patient and surgeon factors.
Main Results:
- Postoperative BCVA was similar between first and second eyes in DSBCS patients.
- Emmetropia rates were comparable across both groups (61-63%).
- No statistically significant difference in BCVA or RE was found between ISBCS and DSBCS, with similar complication rates.
Conclusions:
- ISBCS is not associated with worse visual outcomes or increased complications compared to DSBCS.
- The choice between ISBCS and DSBCS may not significantly impact refractive error outcomes.
- Both surgical timing strategies appear safe and effective for bilateral cataract surgery.
