To evaluate the refractive and visual outcomes following cataract surgery and implantation of a new monofocal non-constant aberration aspheric intraocular lens (IOL).
Ninety eyes of 86 patients who underwent implantation the CT LUCIA 621P IOL (Carl Zeiss Meditec AG) were retrospectively analyzed in this study. Main outcome measures were refractive error and monocular corrected distance visual acuity (CDVA) and monocular uncorrected distance visual acuity (UDVA) values. Patients were evaluated at 1-month post-surgery and intra- and post-operative complications were recorded.
Eighty percent of the eyes showed a CDVA of 20/25 or better before surgery. The postoperative mean values of monocular distance Snellen decimal UDVA and CDVA were 0.64±0.22 and 0.89±0.13, respectively. All eyes showed the same or better difference between UDVA and CDVA. In relation to the postoperative spherical equivalent, the highest percentage of eyes, 31.11%, was for the range between -0.50 and -0.14D followed by 22.22% for the ±0.13D range. Ninety percent of the eyes were within ±1.00 D and 73.33% of eyes within ±0.50 D. The mean postoperative spherical equivalent was -0.18±0.55D. 37.78% and 76.67% of the eyes showed a value ≤0.50 D and ≤1.00D, respectively, being the mean postoperative refractive cylinder -0.81±0.50D. No adverse events were reported in whole sample intra and postoperatively.
The present study shows that cataract surgery with an monofocal non-constant aberration aspheric IOL implantation resulted in good visual performance and refractive outcomes. This lens may be considered as a valid choice for patients in a standard-routine cataract surgery practice.
评估白内障手术后植入新型单焦点非恒定像差非球面人工晶状体（IOL）后的屈光和视觉效果。
本研究回顾性分析了86例患者的90只接受CT LUCIA 621P IOL（卡尔蔡司医疗技术股份公司）植入的眼睛。主要观察指标为屈光不正、单眼矫正远视力（CDVA）和单眼未矫正远视力（UDVA）值。在术后1个月对患者进行评估，并记录术中及术后并发症。
80%的眼睛术前CDVA为20/25或更好。单眼远视力Snellen小数记法的术后平均UDVA和CDVA值分别为0.64±0.22和0.89±0.13。所有眼睛的UDVA和CDVA差异相同或更好。关于术后等效球镜度，最高比例的眼睛（31.11%）处于-0.50至-0.14D范围，其次是±0.13D范围的22.22%。90%的眼睛在±1.00D范围内，73.33%的眼睛在±0.50D范围内。术后平均等效球镜度为-0.18±0.55D。分别有37.78%和76.67%的眼睛等效球镜度≤0.50D和≤1.00D，术后平均屈光柱镜度为-0.81±0.50D。整个样本在术中及术后均未报告不良事件。
本研究表明，植入单焦点非恒定像差非球面IOL的白内障手术具有良好的视觉性能和屈光效果。在标准常规白内障手术中，这种人工晶状体可被视为患者的有效选择。
