Scleral contact lens treatment for corneal contact lens intolerance after keratoplasty

Purpose. The aim of this case report is to describe the treatment of a 47-year-old man with scleral lenses due to intolerance of corneal contact lenses after keratoplasty as a result of keratoconus.

Material and Methods. The initial examinations included visual acuity tests, slit lamp examination and detailed corneal topography using Keratograph 5M and Pentacam AXL Wave. Based on these measurements, scleral lenses were fitted to improve visual acuity and wearing comfort of the contact lenses.

Results. The fitted scleral lenses were subjectively and objectively tolerated without complications the whole day. The visual acuity improved from 0.05 to 1.0 in the right eye and from 0.80p to 1.00 in the left eye.

Conclusion. The fitting of scleral lenses offers many advantages over corneal lenses in cases of corneal ectasia or dry eyes. In this case, scleral lenses provided significantly improved visual results and comfort. Regular follow-up examinations were scheduled to ensure safe and complication-free vision with the contact lenses.
