摘要:
 目的 对比评价白内障超声乳化摘出联合植入散光型人工晶状体(Toricintraoc-ularlens,ToricIOL)及植入球面IOL治疗合并角膜散光的白内障患者的临床疗效。方法 选取在我院就诊的合并角膜规则散光大于1D的白内障患者98例(137眼),分为两组,均行超声乳化白内障摘出术,Toric组联合植入ToricIOL,对照组联合植入球面IOL,术后对比患者的自觉症状、裸眼视力、总和散光、客观视觉质量、IOL柱镜轴位。结果 平均随访12.8个月,术后Toric组的总和散光(0.62±0.36)D要明显小于对照组(1.50±0.33)D,差异有统计学意义(P<0.05);术后1dToric组视力为0.89±0.20,明显高于对照组(0.50±0.13),差异有统计学意义(P<0.05);Toric组术后白天和夜晚不同空间频率下的对比敏感度、调节传递函数截止频率值、100%对比度下视力、20%对比度下视力及患者主观视觉质量的改善程度均优于对照组,差异均有统计学意义(均为P<0.05),而两组9%对比度下视力差异无统计学意义(P>0.05)。Toric组在末次随访时IOL旋转(6.5±3.2)°。结论 与球面IOL相比,ToricIOL能有效地矫正散光,获得良好的主客观视觉质量,具有良好的稳定性。
Abstract:
 Objective To compare the clinical efficacy after phacoemulsification surgery combined Toric intraocular lens ( IOL) with spherical IOL implantation in the treatment of cataract patients with corneal astigmatism. Methods Ninty-eight age-related cataract patients ( 137 eyes) with more than I D of preexisting corneal astigmatism were divided into two groups :the Toric group received the Toric IOL implantation after phacoemulsification . and the control group implanted the spherical IOL. The postoperative symptoms , uncorrected visual acuity , total astigmatism , objective visual quality indicators,IOL cylinder axis position were examined. Results With an average follow-up of 12. 8 months ,the postoperative total astigmatism of the Toric group (0. 62 + 0. 36) D was significantly lower than that of the control group ( 1. 50 + 0. 33 ) D (P < 0. 05 ) . The visual acuity at postoperative I day in Toric group was 0. 89 + 0. 20 , which was higher than that in the control group ( 0. 50 + 0. 13 ) ( P < 0. 05 ) . The improvement of day and night contrast sensitivity in different spatial frequency , MTF cut off value ,visual acuity at 100% contrast, visual acuity at 20% contrast and subjective visual quality of the Toric group were higher than those of the control group ( all P < 0. 05 ) . There was no difference rn visual acuity at g% contrast between the two groups ( P > 0. 05 ) . The mean rotation of IOL in Toric group was ( 6. 5 + 3. 2) 0. Conclusion Compared with the spherical IOL.Toric IOL can effectively correct astigmatism, acquire good subjective and objective visual quality with good rotational stability in the capsular bag.
