Clinical Results of Epikeratoplasty for Myopia, Keratoconus and Aphakia

ABSTRACT

We have performed epikeratoplasty to correct the visual acuity in high myopia who are more than -8.0D and intolerant to the wearing of contract lens, and for the aphakic eyes. It has been also applied to supress the progression of keratoconus. Of 118 eyes performed from january 1989 to july 1992, a total of 90 eyes which could be followed up were subject to the review, including 66 high myopic eyes, 18 keratoconus, and 6 aphakic eyes. In myopic patients, uncorrected visual acuity was stable from a proeperative mean of 0.04 to 0.58 at 4 months. Spherical equivalent was stable from a preoperative mean of -13.99 to -2.01 at 4 months. In keratoconus patients with mean 10.1 months follow-tp, uncorrected visual acuity was changed from 0.05 to 0.33 Corrected viaual acuity was changed from 0.15 to 0.60, keratometry reading was changed from 55.87D to 45.92D. Of 6 aphakic eyes, spherical equivalent of 3 pediatric aphakic eyes under the age of 3 was changed from +15.0D to +3.41, for the other 3 adult aphakic eyes, spherical equivalent was changed from +9.5D to +1.83D and uncorrected visual acuity was changed from 0.03 to 0.32. Epikeratoplasty is effective surgery applicable to the correction of myopia more than -8.0D, keratoconus, and aphakia.
