Ferrara intracorneal ring implantation and cataract surgery for the correction of pellucid marginal corneal degeneration

Abstract

We report a case of Ferrara intracorneal ring (Mediphacos) implantation and cataract surgery for the correction of pellucid marginal corneal degeneration. Preoperatively, the patient's uncorrected visual acuity (UCVA) was 0.05 in the right eye and 0.10 in the left eye. The best spectacle-corrected visual acuity (BSCVA) was 0.50 with −2.00 −11.25 × 80 in the right eye and 0.60 with −2.00 −5.50 × 95 in the left eye. One month postoperatively, the UCVA was 0.50 in the right eye and 0.30 in the left eye. The BSCVA was 0.80 with −1.00 in the right eye and 0.60 with −0.75 −1.25 × 160 in the left eye. Ferrara intrastromal rings and cataract surgery resulted in a more regular corneal shape with a reduction in astigmatism for good visual recovery.
