Mohammad Nooruz Zaman, Sebin C Sebastian

Abstract: Purpose: To manage the complication of post radial keratotomy with corneal scleral lens. Case report: A 55 - year male visited an eye hospital with a complaint of itching in both eyes for one week, he has a history of radial keratotomy done in both eyes 25 years back, his unaided visual acuity for distance RE 6/36 and for LE 6/36p with pinhole the vision in RE 6/12 and in LE 6/9 with corneal irregularities. His best corrected visual acuity was 6/9p in both eyes. We had fitted a corneal scleral lens which has improved the visual acuity and visual comfort. Conclusion: This study suggests that the use of larger diameter lenses will be a good option which will create uniform post lens tears reservoirs that neutralize the optical abnormality of irregular cornea.
