Summary
Endophthalmitis can occur after cataract surgery suture removal, even with antibiotic use. Povidone-iodine 5% is recommended for conjunctival preparation to reduce bacterial counts and prevent infection.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Cataract surgery is a common procedure with potential complications.
- Suture removal is a standard post-operative step.
Observation:
- Three cases of endophthalmitis (intraocular infection) were observed following suture removal after cataract surgery.
- All patients received prophylactic antibiotics prior to suture removal.
Findings:
- Treatment involving vitreous tap and intravitreal antibiotic injection resulted in poor visual outcomes for 2 out of 3 patients.
- Povidone-iodine 5% demonstrated superior efficacy in reducing conjunctival bacterial load compared to topical antibiotics.
Implications:
- Current prophylactic antibiotic protocols may be insufficient to prevent endophthalmitis post-suture removal.
- Povidone-iodine 5% application before suture removal is recommended to enhance ocular surface antisepsis.
- Improved conjunctival preparation protocols are crucial for reducing the risk of post-operative endophthalmitis.
