To analyze 1-week, 1-month, and 12-month postoperative refractive outcomes of eyes that under-went ICL implantation to correct hyperopic astigmatism.
The study enrolled 20 eyes of patients with an average age of 32 years (range: 21 to 40 years). The outcomes of spherical and cylindrical refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), vault, and angle parameters were evaluated 1 week, 1 month, and 12 months postoperatively.
The preoperative mean UDVA was 0.15 ± 0.11 (decimal) (20/133 Snellen) and increased to 0.74 ± 0.25 (20/27 Snellen) postoperatively, with a change of 0.59 (decimal) (20/33.9 Snellen) (P < .0001), which was statistically significant. The preoperative mean CDVA was 0.74 ± 0.25 (decimal) (20/27 Snellen) and increased to 0.78 ± 0.21 (20/25 Snellen), with a change of 0.03 (decimal) (20/666 Snellen) (P < .052), which was not statistically significant. The mean preoperative sphere was 6.86 ± 1.77 diopters (D) and the mean preoperative cylinder was -1.44 ± 0.88 D. The mean 12-month postoperative sphere decreased to 0.46 ± 0.89 D (P < .001) and cylinder decreased to -0.61 ± 0.46 D (P < .001), with a change of 6.40 D, both of which were statistically significant. The mean 1-month postoperative vault was 0.65 ± 0.13 mm and decreased to 0.613 ± 0.10 mm at 1 year postoperatively, with a change of 0.44 mm (P < .003). The preoperative/12-month and 1-month/12-month trabecular-iris angle (TIA), trabecular-iris space area 500 mm from the scleral spur (TISA500), and angle opening distance 500 mm from the scleral spur (AOD500) values were analyzed nasally, temporally, and inferiorly. All differences were statistically significant between preoperative/12-month analysis. The only differences between 1- and 12-month analysis were on TISA500 inferior (P < .002) and AOD500 nasal (0.031) values.
ICL hyperopic toric implantation is a safe method and provides stable refractive outcomes in patients with high hyperopia (up to 10.00 D) and astigmatism (up to 6.00 D). [J Refract Surg. 2017;33(9):604-609.].
分析接受ICL植入术矫正远视散光眼术后1周、1个月和12个月的屈光结果。
该研究纳入了平均年龄32岁（范围：21至40岁）患者的20只眼。分别在术后1周、1个月和12个月评估球镜和柱镜屈光、未矫正远视力（UDVA）、矫正远视力（CDVA）、拱高和房角参数的结果。
术前平均UDVA为0.15±0.11（小数）（20/133 Snellen），术后增至0.74±0.25（20/27 Snellen），变化为0.59（小数）（20/33.9 Snellen）（P <.0001），具有统计学意义。术前平均CDVA为0.74±0.25（小数）（20/27 Snellen），增至0.78±0.21（20/25 Snellen），变化为0.03（小数）（20/666 Snellen）（P <.052），无统计学意义。术前平均球镜为6.86±1.77屈光度（D），术前平均柱镜为-1.44±0.88 D。术后12个月时平均球镜降至0.46±0.89 D（P <.001），柱镜降至-0.61±0.46 D（P <.001），变化分别为6.40 D，均具有统计学意义。术后1个月平均拱高为0.65±0.13 mm，术后1年降至0.613±0.10 mm，变化为0.44 mm（P <.003）。对术前/12个月以及1个月/12个月的小梁-虹膜角（TIA）、距巩膜突500 mm处的小梁-虹膜间隙面积（TISA500）和距巩膜突500 mm处的房角开放距离（AOD500）值进行鼻侧、颞侧和下方分析。术前/12个月分析之间的所有差异均具有统计学意义。1个月和12个月分析之间的唯一差异在于下方的TISA500（P <.002）和鼻侧的AOD500（0.031）值。
ICL远视散光植入术是一种安全的方法，可为高度远视（高达10.00 D）和散光（高达6.00 D）患者提供稳定的屈光结果。[《屈光手术杂志》。2017；33(9)：604 - 609。]
