Penetran Keratoplasti Sonrası Ektazi Nüksü

Corneal ectasia or recurrent keratoconus after penetrating keratoplasty is rare, and few case reports exist in the literature concerning this\udcondition. Computerized corneal topography is quite useful to identify and manage this disorder. Management consists of several methods\udranging from spectacle and contact lens correction to repeated penetrating keratoplasty. Clinical and computerized topography findings of\udtwo patients with keratectasia following penetrating keratoplasty are presented in this article. Two healthy 45-year-old and 25-year-old\udmale patients complained of decreased visual acuity following penetrating keratoplasty. Clinical and topographical data were consistent\udwith recurrence of corneal ectasia. After repeated penetrating keratoplasty, best-corrected distance Snellen visual acuity of 0.7 was obtained\udin the 45-year-old patient. The other patient underwent collagen cross linking, received antiglaucomatous therapy, and his visual acuity\udreached 0.5. During the follow-up period, ectasia progression did not occur.
