To analyze the results of resident-performed laser in situ keratomileusis (LASIK).
Rush University Medical Center, Department of Ophthalmology, Chicago, Illinois, USA.
This retrospective study comprised 44 consecutive eyes of 22 patients who had LASIK performed from August 2000 through February 2002. Based on preoperative spherical equivalent, the eyes were divided into a low myopia group (A) (-1.0 to -6.0 diopter [D]) and a higher myopia group (B) (> -6.01 D). Preoperative and postoperative spherical equivalent (SE), best corrected visual acuity (BCVA), and uncorrected visual acuity (UCVA) were measured and analyzed within each group. Patients had at least 2 follow-up visits, with the second visit occurring between 1 and 9 months postoperatively.
Preoperatively, the mean SE in Group A was -3.93 D +/- 1.53 (SD) and in Group B, -8.49 +/- 1.70 D. At the final visit, the SE in Group A decreased to -0.29 +/- 0.55 D and in Group B, -1.09 +/- 0.87 D. The UCVA in Group A at the final visit was 20/20 or better in 43% of eyes and 20/40 or better in 100% of eyes. In Group B, the UCVA was 20/20 or better in 31% of eyes and 20/40 or better in 75% of eyes. In all eyes, the BCVA improved by 1 line in 16% or remained the same in 84%. No eyes lost any lines of BCVA. The SE taken at the last visit was within +/-0.5 D in 69% of all eyes and within +/-1.0 D in 82% of all eyes. The incidence of patients needing retreatment in resident-performed LASIK surgery was 3 of 44 (6.8%).
Laser in situ keratomileusis performed by residents is a safe and effective procedure for correction of refractive error. Postoperative UCVA, refractive error, retreatment rate, and loss of BCVA were consistent with published results from nonresident surgeons. These results also exceeded the U.S. Food and Drug Administration requirements for LASIK surgery.
分析住院医师实施的准分子原位角膜磨镶术（LASIK）的结果。

这项回顾性研究纳入了2000年8月至2002年2月期间连续接受LASIK手术的22例患者的44只眼。根据术前等效球镜度数，将这些眼分为低度近视组（A组）（-1.0至-6.0屈光度[D]）和高度近视组（B组）（>-6.01 D）。对每组患者术前和术后的等效球镜度数（SE）、最佳矫正视力（BCVA）和未矫正视力（UCVA）进行测量和分析。患者至少接受2次随访，第二次随访在术后1至9个月进行。
术前，A组的平均SE为-3.93 D±1.53（标准差），B组为-8.49±1.70 D。在最后一次随访时，A组的SE降至-0.29±0.55 D，B组降至-1.09±0.87 D。最后一次随访时，A组43%的眼UCVA达到20/20或更好，100%的眼UCVA达到20/40或更好。B组中，31%的眼UCVA达到20/20或更好，75%的眼UCVA达到20/4或者更好。所有眼中，16%的眼BCVA提高了1行，84%的眼BCVA保持不变。没有眼的BCVA下降。最后一次随访时，69%的眼SE在±0.5 D以内，82%的眼SE在±1.0 D以内。住院医师实施的LASIK手术中需要再次治疗的患者发生率为44例中的第3例（6.8%）。
住院医师实施的准分子原位角膜磨镶术是一种安全有效的屈光不正矫正手术。术后UCVA、屈光不正、再次治疗率和BCVA丧失情况与非住院医师外科医生公布的结果一致。这些结果也超过了美国食品药品监督管理局对LASIK手术的要求。
