目的：探讨白内障手术中植入LENTIS Comfort Toric人工晶状体后的视觉质量。

方法：回顾性对照临床研究，收集数字化导航辅助下白内障超声乳化摘除联合人工晶状体植入术患者40例40眼，植入LENTIS Comfort Toric(MF15T)人工晶状体为A组(24眼)，植入单焦点Toric人工晶状体为B组(16眼)； 观察术后3mo不同距离视力、术后散光质心值、脱镜率、离焦曲线变化以及人工晶状体稳定性等。

结果：两组患者术后均无严重并发症出现，两组术后3mo远视力无差异(P>0.05)； A组中视力、近视力明显优于B组(P<0.01)； A组术后脱镜率为99%，B组为45%(P<0.05)； 两组术后3mo散光质心值均较术前改善，但组间无差异(P>0.05)； 术后3mo A组离焦曲线于+0.50、-1.75D分别出现峰值，形成平台并平缓下降，B组于+0.25、-0.25D出现峰值后呈陡峭趋势下降。术后1d A组出现1眼(4%)人工晶状体轴位旋转大于10°； B组出现6眼(38%)人工晶状体轴位旋转大于10°，2眼(33%)顺时针旋转，4眼(67%)逆时针旋转； 两组均无人工晶状体移位发生。

结论：两种人工晶状体均可矫正散光，其中LENTIS Comfort Toric人工晶状体能为白内障合并散光人群提供个性化的选择，可同时解决散光和获得全程视力，术后光学干扰发生率低，稳定性更好，视觉质量及满意度高。

METHODS: A retrospective controlled clinical study was conducted on 40 patients(40 eyes)who received phacoemulsification combined with intraocular lens implantation assisted by digital navigation, with LENTIS Comfort Toric(MF15T)implanted in group A(24 eyes)and monofocal Toric intraocular lens implanted in group B(16 eyes). The visual acuity at different distances, the postoperative astigmatism center of mass value, the lens loss rate, the change of defocus curve and the stability of intraocular lens were observed at 3mo after surgery.

RESULTS: There were no serious complications in both groups, and there was no significant difference in distance vision between group A and group B at 3mo after surgery(P>0.05); the visual acuity and near vision in group A were significantly better than those in group B(P<0.01); the postoperative lens loss rate in group A was 99%, and it was 45% in group B(P<0.05); the value of astigmatism center of mass in 3mo after surgery was improved compared with that before surgery, and there was no significant difference between groups(P>0.05); the defocus curve of group A peaked at +0.50 and -1.75D at 3mo after surgery, forming plateau and gently declining, while group B showed a steep decline after peaks at +0.25 and -0.25D. One eye(4%)in group A had the axial rotation of intraocular lens greater than 10° at 1d after surgery; In group B, 6 eyes(38%)had axial rotation of intraocular lenses greater than 10°, 2 eyes(33%)rotated clockwise, and 4 eyes(67%)rotated counterclockwise. No intraocular lens displacement occurred in either group.

CONCLUSION: Both kinds of intraocular lenses can correct astigmatism, among which LENTIS Comfort Toric intraocular lens can provide personalized choices for people with cataract and astigmatism, solve astigmatism and obtain full visual acuity at the same time, with low incidence of postoperative optical interference, better stability, high visual quality and satisfaction.
