Results of hypermetropic keratomileusis, 1980-1981

The series of cases discussed in this chapter consisted of 135 consecutive cases performed in 120 patients over a two-year period. The first group consisted of 10 cases of hypermetropia with a mean spherical equivalent of +7.75 diopters, a mean uncorrected acuity of 0.14 (20/150) and a mean best corrected acuity of 0.42 (20/50). The mean postoperative spherical equivalent was +1.00, the uncorrected acuity was 0.41 (20/50), and the best corrected acuity was 0.63 (20/30). A second group of 14 cases of monocular aphakia had mean preoperative spherical equivalents of +14.25 and best corrected acuity of 0.62 (20/30). Postoperatively the uncorrected acuity was approximately 0.19 (20/100-), the mean spherical equivalent was +2.85, and the best corrected acuity improved to 0.64 (20/30). The third and largest group consisted of 111 eyes that underwent simultaneous cataract extraction and hypermetropic keratomileusis. Since many of these patients had cataracts, the mean preoperative acuities and refractive errors cannot be adequately analyzed. In the 1980 group, which consisted of 67 cases, postoperatively the average acuity without correction was 0.21 (20/100+) with spherical equivalents of approximately +2.70 diopters. The acuity with the best correction was approximately 0.60 (20/30). In the second group of 40 cases, operated on in 1981, that underwent simultaneous cataract extraction and hypermetropic keratomileusis with a follow-up time half that of the 1980 group, the results were approximately the same.
