Summary
The incidence of acute microbial keratitis following intrastromal corneal ring segment implantation is 1.4%. Management involves explantation of the corneal ring segments and intensive antibiotic treatment.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Infectious Diseases
Background:
- Intrastromal corneal ring segments are used to correct refractive errors.
- Assessing the risk of infection after implantation is crucial for patient safety.
Observation:
- This study evaluated 212 eyes undergoing intrastromal corneal ring segment implantation.
- Both Intacs and Ferrara rings were used, with manual and femtosecond laser techniques.
Findings:
- Three cases (1.4%) of acute microbial keratitis were identified.
- Gram-positive cocci, including Streptococcus mitis and Staphylococcus aureus, were isolated.
- No significant difference in keratitis incidence was found between ring types or surgical techniques.
Implications:
- Acute microbial keratitis is a rare but serious complication of corneal ring segment implantation.
- Prompt explantation and aggressive topical antibiotic therapy are essential for successful management.
- Further research may explore preventative strategies to minimize infection risk.
