Management of superior pellucid marginal degeneration with a single intracorneal ring segment using femtosecond laser.

Abstract

PURPOSE:

A 26-year-old man with superior pellucid marginal corneal degeneration associated with poor visual acuity due to irregular astigmatism was treated with single-segment intracorneal ring insertion.

METHODS:

Preoperatively the patient's uncorrected visual acuity (UCVA) was 0.05, best spectacle-corrected visual acuity (BSCVA) was 0.15, and manifest refraction was -4.50 x 85 in the left eye. The flattest meridian (K1) measured was 38.50 x 90 and the steepest meridian (K2) was 51.10 x 30.

RESULTS:

Three months postoperatively, UCVA was 0.15, BSCVA was 0.4, and manifest refraction was -2.50 x 90.

CONCLUSIONS:

The use of single Intacs with femtosecond laser to treat superior pellucid marginal corneal degeneration improved visual acuity.
