Abstract
Purpose
To evaluate patient satisfaction after implantation of the Tecnis Symfony multifocal intraocular lens (MIOL).
Methods
120 eyes of 60 subjects with senile cataract were bilaterally implanted with the Tecnis Symfony IOL. Follow-up examination was performed 6 months postoperatively. Main outcome measures included uncorrected and corrected distance and near visual acuity, manifest refraction, and visual quality metrics. According to their subjective symptoms patient were divided in two groups: satisfied and unsatisfied.
Results
Uncorrected intermediate (0.15 ± 0.11 vs 0.18 ± 0.01, P = 0.04) and near (0.26 ± 0.12 vs 0.31 ± 0.11, P = 0.04) (UIVA, UNVA) log MAR visual acuity was significantly better, cylindrical error less (0.31 ± 0.36 vs 0.67 ± 0.29, P = 0.05), axial length (AL) smaller (23.68 ± 1.3 vs 24.22 ± 1.6, P = 0.05), Strehl ratio higher (0.08 ± 0.08 vs 0.05 ± 0.04, P = 0.03) and mesopic pupil larger (4.3 ± 1.1 vs 3.7 ± 1.05, P = 0.01) among satisfied patients.Residual cylinder, Strehl ratio, halos, mesopic pupil diameter and UNVA were significant predictors of patient satisfaction. Uncorrected distance visual acuity, higher order Strehl ratio and pupil diameter were significant predictors of halos. Near visual acuity significantly correlated (P = 0.018, R = 0.22) with axial length.
Conclusions
Uncorrected cylindrical error, poor reading quality, larger pupil and halos seem to be the most disturbing factors for patients implanted with the Tecnis Symfony IOL.
目的评价Tecnis Symfony多焦人工晶体植入术后患者的满意度。方法对60例老年性白内障患者120眼行双侧人工晶状体植入术。术后6个月随访。主要结果测量包括未矫正和矫正的远近视力、明显屈光和视觉质量指标。根据主观症状将患者分为满意组和不满意组。ResultsUncorrected中间(0.15±0.11 vs 0.18±0.01,P = 0.04)和附近的(0.26±0.12 vs 0.31±0.11,P = 0.04) (UIVA UNVA)日志3月视力明显更好,圆柱形错误更少的(0.31±0.36 vs 0.67±0.29,P = 0.05),轴向长度(AL)小(23.68±1.3 vs 24.22±1.6,P = 0.05), Strehl率较高(0.08±0.08 vs 0.05±0.04,P = 0.03)和黄昏黎明瞳孔较大(4.3±1.1 vs 3.7±1.05,P = 0.01)在满足病人。残柱面、施特雷氏比、光晕、介视瞳孔直径和UNVA是患者满意度的显著预测因子。未校正距离视力、高阶Strehl比和瞳孔直径是光晕发生的显著预测因子。近视力与眼轴长度显著相关(P = 0.018, R = 0.22)。结论未矫正的柱形误差、阅读质量差、瞳孔较大和光晕是影响Tecnis Symfony人工晶状体植入术的主要因素。
