比较单步经上皮屈光性角膜切削术(PRK)和飞秒辅助准分子激光原位角膜磨镶术(LASIK)的术后临床疗效。

回顾性病例系列。
回顾性比较了连续接受过上皮PRK的患者的眼睛与相同数量的经飞秒辅助LASIK治疗的病例匹配眼睛(基于术前屈光成分)。评估的临床结果是可预测性,屈光结果,和视力。采用Studentt检验和卡方检验进行统计分析。
该研究比较了98例(196只眼)经上皮PRK患者与196例匹配的经飞秒辅助LASIK患者的结局。所有患者均完成1年随访。在1年,经上皮PRK组的130只眼(66%)和飞秒辅助LASIK组的91只眼(46%)获得了-0.1logMAR或更好(P<.005)的未矫正视力,经上皮PRK组的4只眼(2%)和飞秒辅助LASIK组的2只眼(1%)失去了2行矫正视力(P=.04),经上皮PRK组的163只眼(83%)和飞秒辅助LASIK组的167只眼(85%)在正视屈光度(D)±0.50内。经上皮PRK的术后平均球面当量为+0.11D±0.56(SD),飞秒辅助LASIK的术后平均球面当量为-0.09±0.46D(P<0.0001)。
术后1年经上皮PRK的结果与飞秒辅助LASIK的结果相当。经上皮PRK是有效和安全的;然而,与飞秒辅助LASIK相比,该手术恢复时间更长.

To compare the postoperative clinical outcomes of single-step transepithelial photorefractive
keratectomy (PRK) and femtosecond-assisted laser in situ keratomileusis (LASIK).
Bergman Clinics, Utrecht, the Netherlands.
Retrospective
case series.
The eyes of consecutive patients who had transepithelial PRK were retrospectively compared with the same number of
case-matched eyes (based on the preoperative refractive components) treated with femtosecond-assisted LASIK. The clinical outcomes evaluated were predictability, refractive outcomes, and visual acuity. The Student t test and chi-square test were used for statistical analysis.
The study compared 98 patients (196 eyes) who had transepithelial PRK with the outcomes in 196
case-matched eyes that had femtosecond-assisted LASIK. All patients completed the 1-year follow-up. At 1 year, 130 eyes (66%) in the transepithelial PRK group and 91 eyes (46%) in the femtosecond-assisted LASIK group achieved an uncorrected distance visual acuity of -0.1 logMAR or better (P < .005), 4 eyes (2%) in the transepithelial PRK and 2 eyes (1%) in the femtosecond-assisted LASIK group lost 2 lines of corrected distance visual acuity (P = .04), and 163 eyes (83%) in the transepithelial PRK and 167 eyes (85%) in the femtosecond-assisted LASIK group were within ±0.50 diopter (D) of emmetropia. The postoperative mean spherical equivalent was +0.11 D ± 0.56 (SD) for transepithelial PRK and -0.09 ± 0.46 D for femtosecond-assisted LASIK (P < .0001).
Transepithelial PRK outcomes 1 year postoperatively were equivalent to those of femtosecond-assisted LASIK. Transepithelial PRK was efficacious and safe; however, the procedure had a longer recovery time than the femtosecond-assisted LASIK.
