Abstract

BACKGROUND:

Epikeratoplasty for keratoconus, in the absence of apical scarring, aims at reducing high irregular myopic astigmatism and provides an ectatic cornea with mechanical support.

METHODS:

We performed epikeratoplasty on 11 keratoconic corneas using fresh or McCarey-Kaufman preserved, manually dissected donor lenticules. A disparity of 0.5 mm was maintained between the host and the donor. Patients with keratoconus having a preoperative spectacle-corrected visual acuity of less than 6/60 and intolerance to contact lens wear were included in this prospective study. Spectacle-corrected visual acuity, keratometry, and refraction were analyzed over a 4-year follow-up period.

RESULTS:

Four year follow-up was completed on 10 eyes. Of these, 80% achieved a postoperative spectacle-corrected visual acuity of 6/12 or better. Average postoperative keratometry was 45.79 +/- 2.07 D and a decrease of 4.60 +/- 0.09 D was observed in refractive cylinder. Spherical equivalent showed a significant decrease in myopia of -4.35 +/- 0.26 D. Mean time to stabilization was 8 +/- 2.3 weeks. Epithelial defects occurred in three eyes; two were successfully treated by patching. One lenticule was removed due to graft infection following a persistent epithelial defect.

CONCLUSION:

Epikeratoplasty for keratoconus is a useful procedure with good long-term visual acuity results and an early stabilizing period.
