Summary
Corneal infection is a risk following radial keratotomy (RK). Prompt diagnosis and treatment are crucial for managing these infections and preserving vision after RK surgery.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Radial keratotomy (RK) is a refractive surgical procedure.
- Corneal infections can be a serious complication following RK.
Purpose of the Study:
- To evaluate nine eyes that developed corneal infection after RK.
- To assess the management of post-RK corneal infections.
Main Methods:
- Reviewed cases of corneal infection post-RK.
- Assessed parameters: interval to ulcer, number of incisions, surgery type, presentation status, and visual acuity.
- Performed microbiological evaluation of corneal scrapings.
- Initiated therapy based on clinical impression and microbiological results.
Main Results:
- Staphylococcus species and Pseudomonas aeruginosa were common isolates.
- Two cases showed fungal growth; one had no growth.
- Most eyes responded to medical therapy within 23-26 days.
- One eye required therapeutic penetrating keratoplasty (PKP).
- Visual acuity improved significantly after treatment.
Conclusions:
- Corneal infection is a potential complication of RK.
- Persistent postoperative irritation warrants careful observation for early diagnosis.
- Prompt therapy is essential for favorable outcomes.
