在全国范围内的外角膜晶状体研究中，116名眼科医生进行了352例近视矫正手术；256只眼在拆线后随访30天以上。204只眼中，153只（75%）术后近视程度在30%以内。在208只眼中，202只（97%）的术后最佳矫正视力在两条斯伦线以内或优于术前视力。除一名患者外，其余患者的未矫正视力均有所改善。在120例达到或改善术前最佳矫正视力的患者中，116例（97%）在拆线后30至60天内达到术前测量的两条Snellen线范围内。角膜散光从术前平均（±sd） 1.4±0.8屈光度变化到术后平均2.6±2.1屈光度。352个组织晶状体中，36个（10%）被移除，主要是由于不准确的力量、腐烂或上皮再生失败，其中17只眼睛进行了第二次成功的角膜外晶状体手术。
In the nationwide study of epikeratophakia, 116 ophthalmic surgeons performed 352 procedures for the correction of myopia; 256 of the eyes had 30 or more days of follow-up after suture removal. Of 204 eyes, 153 (75%) were within 30% of emmetropia after surgery. Of 208 eyes, 202 (97%) had postoperative best corrected visual acuity within two Snellen lines or better of their preoperative visual acuity. All but one patient improved uncorrected visual acuity. Of the 120 patients who equaled or improved their preoperative best corrected visual acuity, 116 (97%) were within two Snellen lines of their preoperative measurement between 30 and 60 days after suture removal. Corneal astigmatism changed from a preoperative mean (± S.D.) of 1.4 ± 0.8 diopters to a postoperative mean of 2.6 ± 2.1 diopters. Of 352 tissue lenses, 36 (10%) were removed, largely as a result of inaccurate power, decay, or failure to reepithelialize, and 17 of these eyes underwent a second successful epikeratophakia procedure.
