目的:观察Toric人工晶状体(intraocular lens, IOL)植入用于治疗合并角膜散光的白内障患者的临床治疗效果。
方法:对41例47眼合并角膜散光的白内障患者行超声乳化白内障吸出及IOL植入术治疗,进行回顾性分析。其中22眼植入Toric IOL,25眼植入Acrysof IQ IOL。术后随访6mo,分析不同时间点裸眼视力、术后残余散光、并发症等,比较两种IOL的疗效。观察Toric IOL植入后的稳定性。
结果: 术后随访观察6mo,植入Toric IOL的试验组,术后裸眼视力平均0.73±0.37,明显优于植入Acrysof IQ IOL的对照组(平均0.47±0.18),结果有显著性差异。试验组术后裸眼视力0.5以上者占81.8%,优于对照组32.0%。试验组患者术后残余散光0.53±0.40D,明显低于对照组(2.13±0.76D),差异有统计学意义。植入Toric IOL组,随访6mo,术后平均旋转4.22±1.46度。
结论:对于合并角膜散光的白内障患者,行白内障超声乳化吸出联合Toric IOL植入,能够安全、有效的改善患者的散光,提高术后视觉质量,预测性好。

[Abstract]
AIM: To evaluate toric intraocular lens(IOL)implantation as a treatment of regular corneal astigmatism during phacoemulsification.
METHODS: Forty-seven eyes in 41 patients with cataract and corneal astigmatism had toric IOL(22 eyes)or spherical IOL(25 eyes)implantation during phacoemulsification. Outcome measures were uncorrected distance visual acuity(UDVA), best-corrected distance visual acuity(BCDVA), postoperative refractive cylinder, toric IOL axis rotational stability and complications.
RESULTS: Six months postoperatively, the mean UDVA was(0.73±0.37)in toric IOL group and(0.47±0.18)in spherical IOL group; the UDVA was better than 0.50 of 81.8% and 32.0% in two groups, respectively. The residual astigmatism was(0.53±0.40)D in toric IOL group and(2.13±0.76)D in spherical IOL group. The mean toric IOL misalignment was(4.22±1.46)degrees.
CONCLUSION: Implantation of toric IOL during cataract surgery is effective, predictable and safe in correcting corneal astigmatism.
