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.
