Summary
Corneal topography revealed unsuspected borderline keratoconus in two patients considered for radial keratotomy. This condition is a contraindication for refractive surgery, highlighting the importance of thorough pre-operative screening.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Imaging
Background:
- Radial keratotomy is a refractive surgical procedure to correct myopia.
- Patient selection is critical for successful refractive surgery outcomes.
- Corneal topography is an advanced diagnostic tool for assessing corneal shape and health.
Observation:
- Two patients evaluated for radial keratotomy presented with previously undiagnosed borderline keratoconus.
- The subclinical keratoconus was identified through detailed corneal topography analysis.
- This finding was unexpected based on initial clinical examination.
Findings:
- Borderline keratoconus was detected in patients undergoing pre-operative assessment for radial keratotomy.
- Corneal topography proved essential in revealing this unsuspected pathology.
- The presence of keratoconus contraindicates radial keratotomy and other refractive surgeries.
Implications:
- Thorough pre-operative screening using corneal topography is crucial for identifying contraindications like keratoconus.
- Undiagnosed keratoconus can lead to adverse outcomes if refractive surgery is performed.
- This case underscores the importance of advanced imaging in patient safety for elective eye surgery.
