Penetrating keratoplasty for keratoconus: visual outcome and success1☆,
Section snippets
Patients and methods
A retrospective review was conducted of patients with keratoconus who received a penetrating keratoplasty by one surgeon (DJC) from January 1988, to May 30, 1995. The sources of information were the Australian Corneal Graft Registry database, hospital records, and, where applicable, the records of optometrists and ophthalmologists who referred these patients. The data collected included patient demographic information, age at which penetrating keratoplasty was performed, surgical variables
Results
Outcome was assessed in terms of graft survival, postoperative complications, and visual rehabilitation as measured by Snellen and logMAR acuity, keratometry, residual cylinder, and method of correction.
Discussion
Penetrating keratoplasty for keratoconus was performed in relatively young patients (mean age, 31.6 years at the time of keratoplasty) with a slight male predominance of 55%. Thirty-two percent of our patients had a history of atopy.
Contact lens intolerance was the main indication for keratoplasty, and this is comparable to other series.11, 12 Forty-five percent of eyes were intolerant of contact lenses, and these patients depended on vision in the other eye before keratoplasty.
