To evaluate the refractive and the quality of vision outcomes of toric IOL implantation in patients with low astigmatism. Prospective study of single-arm. Patients with corneal astigmatism range from 0,75 D to 1,5 D and cataract that underwent cataract surgery with toric IOL. The measurements were performed preoperatively and 6 weeks after the surgery. Patients were evaluated for visual acuity with and without correction, contrast sensitivity, static and dynamic refraction, and quality of life questionnaire. Pre- and postoperative values were compared and their variations were evaluated for linear correlation. 21 eyes of 21 patients. Postoperative mean uncorrected visual acuity was 0.80 ± 0.19, and the best corrected visual acuity was 0.97 ± 0.15. < 0.001 compared to preoperative values. The average postoperative refractive cylinder was -0.34 ± 0.39. The questionnaire's total value before and after surgery was, respectively, 43.20 ± 15.76 and 79.70 ± 10.11 ( < 0.001). The correlation coefficients between the values of the questionnaire variation and the UCVA, BCVA, and CS variation were, respectively, 0.548 ( = 0.005), 0.508 ( = 0.009), and 0.409 ( = 0.033). Patients with low astigmatism who underwent phacoemulsification with toric IOL implantation experienced significant decrease in refractive astigmatism and improvement in their quality of life.
评估低散光患者植入散光型人工晶状体后的屈光状态及视觉质量。单臂前瞻性研究。纳入角膜散光范围为0.75 D至1.5 D且因白内障接受散光型人工晶状体植入白内障手术的患者。术前及术后6周进行测量。对患者进行矫正和未矫正视力、对比敏感度、静态和动态屈光以及生活质量问卷评估。比较术前和术后值,并评估其变化的线性相关性。21例患者的21只眼。术后平均未矫正视力为0.80±0.19,最佳矫正视力为0.97±0.15。与术前值相比,P<0.001。术后平均屈光柱镜为-0.34±0.39。手术前后问卷总分分别为43.20±15.76和79.70±10.11(P<0.001)。问卷变化值与未矫正视力、最佳矫正视力及对比敏感度变化值之间的相关系数分别为0.548(P=0.005)、0.508(P=0.009)和0.409(P=0.033)。接受散光型人工晶状体植入白内障超声乳化术的低散光患者屈光性散光显著降低,生活质量得到改善。
