摘　　要：目的 评价白内障病人植入AcrySof toric 人工晶状体（IOL）对术前存在的角膜散光矫正的疗效.方法 选择伴角膜规则性散光的白内障病人23例（33只眼）,行超声乳化术并植入AcrySof Toric IOL,术前术后检查裸眼视力（UCVA）、最佳矫正视力（BCVA）,术前查角膜散光,术后检查残余散光、Toric IOL散光轴的偏离情况.结果 术后UCVA为0.71±0.21,85%≥0.5,67%≥0.8,BCVA为0.82±0.25,94%≥0.5,82%≥0.8.术前角膜散光（2.57±0.95）D,术后残余散光（0.64±0.32）D（P＜0.01）.术前预计矫正散光（1.98±0.39）D,实际矫正散光（1.89± 0.77）D（P＞0.05）.实际矫正散光度数/预计矫正散光度数≥50% 为91%,≥70%为（79%）,≥90%为52%,≥100%为33%,＞100% 为18%;术后IOL散光轴位偏离为（3.15±1.79）°,100%≤10°.结论 AcrySof toric IOL是一种有效、安全、简便、预测性好的治疗白内障合并角膜规则散光的方法.Objective To evaluate the effect of AcrySof Toric intraocular lens （IOL） implantation to correct preexisting corneal astigmatism in cataract surgery. Methods This study included 33 eyes of 23 patients with Preexisting corneal astigmatism having cataract surgery. The implantation of the AcrySof Toric IOL was performed after phacoemulsification. The uncorrected visual acuity （UCVA）, the best corrected visual acuity （BCVA）, preexisting corneal astigmatism, residual astigmatism and Toric IOL axis were measured. Results The postoperative UCVA was 0.71±0.21, 0.5 or better in 85% of eyes, 0.8 or better in 67%. The postoperative BCVA was 0.82±0.25, 0.5 or better in 94% of the eyes, 0.8 or better in 85%. The mean refractive cylinder decreased significantly after surgery from （2.57±0.95）D to （0.64±0.32）D （P 〈0.01）. The anticipated correction was （1.98±0.39）D. The achieved correction was （1.89± 0.77）D （P 〉0.05）. The achieved correction / The anticipated correction was ≥50% in 91%, ≥70% in 79%, ≥90% in 52%, ≥100% in 33%, 〉100% in 18%, respectively. The mean Toric IOL misalignment was （3.15±1.79） degrees, less than 10° in 100% of the eyes. Conclusions The results indicate that AcrySof Toric IOL implantation is an effective, safe and predictable method to correct corneal astigmatism in cataract surgery.
