Association between Increased Cataract Surgery Duration and Postoperative Outcomes

Area of Science:

• Ophthalmology
• Surgical Outcomes
• Patient Recovery

Background:

• Cataract surgery is a common procedure with generally excellent outcomes.
• Understanding factors influencing post-operative recovery is crucial for patient management.
• Surgical duration is a potential, yet understudied, variable in cataract surgery outcomes.

Purpose of the Study:

• To investigate the association between prolonged surgical duration and post-operative outcomes in patients undergoing uncomplicated cataract surgery.
• To identify specific outcomes affected by longer phacoemulsification times.

Main Methods:

• Retrospective cohort study utilizing data from a large ophthalmology database.
• Analysis of uncomplicated cataract extractions performed between 2014 and 2018.
• Comparison of outcomes between 'long' ( > 1 SD above mean) and 'non-long' surgery groups using univariate and multivariate analyses.

Main Results:

• Longer surgeries (13.2% of cases) did not correlate with increased postoperative inflammation.
• Prolonged surgery duration was associated with a higher incidence of Nd:YAG capsulotomy (OR 1.42).
• Poorer uncorrected and best-corrected visual acuity was observed in the long surgery group at early post-operative intervals.

Conclusions:

• Patients with longer cataract surgery durations may experience a slower visual recovery and increased risk of posterior capsular opacification.
• Despite some differences, most outcomes for uncomplicated cataract surgeries are comparable regardless of duration.
• Counseling patients on potential slower recovery after longer procedures is advisable.
