Abstract
Penetrating keratoplasty (PK) may be required for visual rehabilitation or tectonic purposes in patients with severe keratopathy due to atopic keratoconjunctivitis (AKC). The outcome of PK is often poor in such patients because of adnexal and ocular surface abnormalities. We studied nine AKC patients requiring PK and evaluated the visual outcome and prognostic factors in 11 eyes. The mean follow-up was 87.2 months (range, 30–180 months). Pre-operatively all patients had visual acuity of hand motion to 20/200. Eighteen grafts were performed. Final visual acuity was 20/40 or better in 46% of the eyes. Ten eyes retained clear grafts and improved an average of 4.5 Snellen acuity lines.
