To analyze the visual and refractive outcomes of laser in situ keratomileusis (LASIK) after deep anterior lamellar keratoplasty (DALK) for keratoconus.

Cohort study.
Patients with compound myopic astigmatism after DALK and a spherical equivalent (SE) between -2.50 diopters (D) and -8.00 D had LASIK as a single-step procedure, correcting the manifest refraction error. The visual and refractive results at 1 month, 3 months, and the last follow-up were compared with preoperative values.
The mean follow-up was 11.17 months ± 3.61 (SD). The mean manifest refraction SE (MRSE) and autorefractometer measurements and the autokeratorefractometer and corneal topography keratometry readings decreased significantly from preoperatively to 1 month postoperatively (P<.01) but did not change significantly thereafter (P>.05). Preoperatively, the mean uncorrected (UDVA) and corrected (CDVA) distance visual acuities were 0.21 ± 0.08 and 0.73 ± 0.08, respectively; postoperatively, the means were 0.73 ± 0.10 and 0.98 ± 0.05, respectively. All eyes achieved a postoperative UDVA better than 0.5. No eye lost CDVA lines. The safety index was 1.34. The mean MRSE was -5.18 ± 1.74 D preoperatively and -1.05 ± 0.64 D postoperatively (P<.01). Postoperatively, 11 eyes (91.67%) were within ± 2.00 D of the SE, 8 (6.67%) were within ± 1.00 D, and 5 (41.67%) were within ± 0.50 D. No complications were encountered.
Treatment of post-DALK keratoconus patients with LASIK to correct manifest refraction error seems to be a viable option.
分析 LASIK 治疗深层板层角膜移植术后圆锥角膜的视力和屈光结果。

队列研究。
对接受深层板层角膜移植术后存在复合性近视散光且等效球镜（SE）在-2.50 屈光度（D）和-8.00 D 之间的患者进行 LASIK 单步手术，以矫正视力。将术后 1 个月、3 个月和最后一次随访的视力和屈光结果与术前值进行比较。
平均随访时间为 11.17 个月±3.61（SD）。从术前到术后 1 个月，平均 SE（MRSE）和自动折射计测量值以及自动角膜折射计和角膜地形图角膜曲率读数显著降低（P<.01），但此后无显著变化（P>.05）。术前，未矫正（UDVA）和矫正（CDVA）距离视力分别为 0.21±0.08 和 0.73±0.08；术后，平均值分别为 0.73±0.10 和 0.98±0.05。所有眼术后 UDVA 均优于 0.5。无眼丢失 CDVA 线。安全性指数为 1.34。术前平均 MRSE 为-5.18±1.74 D，术后为-1.05±0.64 D（P<.01）。术后，11 只眼（91.67%）在 SE 的±2.00 D 以内，8 只眼（6.67%）在±1.00 D 以内，5 只眼（41.67%）在±0.50 D 以内。未发生并发症。
LASIK 治疗深层板层角膜移植术后圆锥角膜以矫正视力的方法似乎是可行的。
