Study population

Groups and cohorts

• mild to moderate keratoconus cases

  keratoconus with a central corneal thickness (CCT) over 400µm, poor corrected visual acuity (≤0.4 at Snellen visual acuity charts), contact lens intolerance, no apical scarring, no ocular or systemic problem other than keratoconus

  Procedure: radial keratotomy

Interventions

• Procedureradial keratotomy

Primary outcomes

1. outcome measures: uncorrected and best spectacle corrected visual acuity, keratometer readings

   Preoperative and postoperative uncorrected visual acuity, best spectacle corrected visual acuity, and keratometer readings will be reviewed retrospectively. As reviewed follow up time range is 12 to 52 months, time frame is assessed as " 12 to 52 months"

   Time frame: after surgery - 12 to 52 months
