An ocular surface prosthetic can treat discomfort and improve visual function in patients with irregular corneas who were unresponsive to prior conventional treatments, according to a study.
The retrospective study included 90 eyes of 58 patients with irregular corneas who were fitted with Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) scleral lenses.
Forty-three percent of patients had keratoconus, and 31% had post-PK astigmatism.
Keratoconus patients had an 88% improvement in logMAR visual acuity, whereas patients with post-PK astigmatism had a 79% improvement in Ocular Surface Disease Index scores.
