Bilateral versus unilateral cataract extraction: advantages and complications

Area of Science:

• Ophthalmology
• Surgical Outcomes

Background:

• Cataract is a leading cause of vision impairment globally.
• Surgical extraction remains the primary treatment for cataracts.

Purpose of the Study:

• To evaluate the visual outcomes and complication rates of cataract extraction.
• To compare outcomes between bilateral (simultaneous) and unilateral cataract surgeries.

Main Methods:

• Retrospective analysis of 1182 cataract extractions in 734 patients.
• Follow-up for up to 1 year post-surgery.
• Comparison of visual acuity and complication incidence between bilateral and unilateral procedures.

Main Results:

• Preoperatively, >75% of eyes had only light perception.
• Postoperatively, >85% of eyes achieved visual acuity of 6/30 or better.
• Visual performance and complication rates were similar for bilateral and unilateral surgeries.

Conclusions:

• Cataract extraction significantly restores vision.
• Simultaneous bilateral cataract surgery is as safe and effective as unilateral surgery.
• Low incidence of severe complications, with vision restoration successful in most cases.
