The refractive results of 43 consecutive triple procedures (transplant, cataract extraction, and lens implant) performed by one surgeon were analyzed. Twenty-one out of 43 eyes achieved refractive errors within 2 diopters (D) of emmetropia. The mean refractive error was -1.79 D, and the mean corneal astigmatic error was 2.75 D. Seventy percent of the eyes achieved 20/40 or better corrected acuity. Forty-four percent had 20/80 or better uncorrected acuity. Using the average postoperative keratometry readings from other recent transplant cases and an updated A constant in the SRK regression formula would have placed 39 of 43 eyes (91%) within 2 D of emmetropia with a mean refractive error of -0.07 D. The use of recent keratometry readings in a multiple regression formula is recommended to improve refractive results with the triple procedure.
分析了由一位外科医生连续进行的43例三联手术（移植、白内障摘除和晶状体植入）的屈光结果。43只眼中有21只眼的屈光不正度数在正视眼的2屈光度（D）范围内。平均屈光不正度数为-1.79 D，平均角膜散光度数为2.75 D。70%的眼睛矫正视力达到20/40或更好。44%的眼睛未矫正视力达到20/80或更好。使用近期其他移植病例的平均术后角膜曲率计读数以及SRK回归公式中更新的A常数，43只眼中有39只眼（91%）的屈光不正度数在正视眼的2 D范围内，平均屈光不正度数为-0.07 D。建议在多元回归公式中使用近期角膜曲率计读数，以改善三联手术的屈光结果。
