A new contact lens design for post-keratoplasty patients

We conducted a study of 25 post-penetrating keratoplasty (PK) patients (28 eyes) fit with Quintasphere PK rigid gas permeable contact lenses. Using the Quintasphere PK trial set, 96% of patients were successfully wearing the lens at 6 months; at 1 year 93% were successfully wearing the lens. Eighty-two percent of eyes fit achieved at least 20/40 visual acuity, and 93% achieved at least 20/50. The average number of lenses fit per eye was 1.29. The design basis of the Quintasphere PK lens was predicated on a plateau-shaped corneal graft.
