We studied 75 epikeratoplasty procedures using nonlyophilized tissue performed by eight ophthalmic surgeons in 70 eyes (47 patients) to correct for aphakia in children less than 8 years of age (mean age, 3.4 +/- 2.1 years). Of the 47 patients in the study, 24 were girls and 23 were boys; 23 patients had bilateral surgery. Seven of the epigrafts required removal; two were not replaced, and five underwent successful repeat epikeratoplasty. Overall, the success rate (that is, the percentage of epigrafts that remained optically and functionally clear throughout the course of this study) for the epikeratoplasty procedure was 89% (62 of 70 eyes) for initial surgery and 96% (67 of 70 eyes) for repeat surgery. The average spherical equivalent was +14.4 +/- 3.7 diopters preoperatively and +0.3 +/- 2.9 diopters one year after the operation. One year after the final surgical procedure, 42 of 56 eyes (75%) were within 3 diopters of emmetropia. In the 29 verbal patients, best-corrected visual acuity was 20/100 or better in 25 (86.2%) one year after the operation.
我们研究了8位眼科医生为70只眼(47例患者)实施的75例使用非冻干组织的角膜表层镜片移植手术,以矫正8岁以下儿童(平均年龄3.4±2.1岁)的无晶状体状态。在该研究的47例患者中,24例为女孩,23例为男孩;23例患者接受了双侧手术。7片角膜表层镜片需要移除;2片未更换,5片成功接受了重复角膜表层镜片移植手术。总体而言,角膜表层镜片移植手术的成功率(即,在本研究过程中保持光学和功能清晰的角膜表层镜片的百分比),初次手术为89%(70只眼中的62只),重复手术为96%(70只眼中的67只)。术前平均球镜当量为+14.4±3.7屈光度,术后一年为+0.3±2.9屈光度。在最后一次手术后一年,56只眼中的42只(75%)屈光不正度数在正视眼的3屈光度范围内。在29例能言语交流的患者中,术后一年25例(86.2%)的最佳矫正视力为20/100或更好。
