Comparative case series.
The differences in visual acuity and residual refractive outcomes after wavefront-guided PRK and Artiflex foldable pIOL implantation were compared in eyes with low to moderate myopia (spherical error -4.0 to -7.0 diopters [D]; maximum cylinder 2.25 D). One-year follow-up results are presented.
At 1 year postoperatively, the mean decimal Snellen uncorrected distance visual acuity was 1.05 ± 0.21 (SD) in the PRK group (60 eyes) and 1.04 ± 0.21 in the pIOL group (33 eyes) and the mean corrected distance visual acuity (CDVA), 1.21 ± 0.18 and 1.24 ± 0.13, respectively. In the PRK group, 21.7% of eyes lost 1 to 3 lines of CDVA and 11.7% of eyes gained 1 or 2 lines. In the pIOL group, no eye lost lines of CDVA and 42% gained 1 or 2 lines. At 1 year, 80.0% of eyes in the PRK group and 90.9% of eyes in the pIOL group were within ± 0.50 D of the spherical equivalent.
There were no statistically significant differences in safety and efficacy between the pIOL group and the PRK group at 1 year. However, the percentage of eyes that gained lines of CDVA was significantly higher in the pIOL group.

对比病例系列。
比较低中度近视（球镜误差-4.0 至-7.0 屈光度[D]；最大柱镜 2.25 D）患者接受波前引导性 PRK 和 Artiflex 可折叠 pIOL 植入术后的视力和残留屈光结果的差异。报告 1 年随访结果。
术后 1 年，PRK 组（60 只眼）平均十进制 Snellen 未矫正远视力为 1.05 ± 0.21（标准差），pIOL 组（33 只眼）为 1.04 ± 0.21，平均矫正远视力（CDVA）分别为 1.21 ± 0.18 和 1.24 ± 0.13。PRK 组中有 21.7%的眼丧失 1 至 3 行 CDVA，11.7%的眼增加 1 或 2 行。在 pIOL 组中，没有眼丧失 CDVA 行数，有 42%的眼增加 1 或 2 行。术后 1 年，PRK 组 80.0%的眼和 pIOL 组 90.9%的眼屈光度等效球镜误差在±0.50 D 以内。
在 1 年时，pIOL 组和 PRK 组在安全性和疗效方面没有统计学差异。然而，pIOL 组获得 CDVA 行数的眼比例明显更高。
