To analyze the refractive and visual outcomes following cataract surgery and implantation of a trifocal toric intraocular lens (IOL) in eyes with high degrees of corneal astigmatism.
A total of 29 eyes from 21 patients who underwent implantation of a trifocal toric IOL (FineVision PODFT; PhysIOL) were evaluated in this study. Phacoemulsification with femto-second laser and intraoperative aberrometry were performed in all cases. All IOLs used exhibited a cylinder power of 3.75 diopters (D) or greater. The main outcome measures were refractive error and corrected distance visual acuity (CDVA) and uncorrected distance visual acuity (UDVA) values. Eyes were evaluated during a follow-up period of 5 years.
A total of 96.30%, 100%, 95.83%, and 89.47% of eyes were within ±1.00 D at 1, 2, 3, and 5 years postoperatively, respectively. Furthermore, 92.31%, 86.36%, 82.61%, and 84.21% of eyes showed a refractive cylinder value of ±1.00 D at 1, 2, 3, and 5 years postoperatively, respectively. During the entire follow-up period, between 81.48% and 91.30% of eyes showed a CDVA of 20/25 or better. The mean monocular Snellen decimal CDVA values were 0.90 ± 0.12, 0.90 ± 0.11, 0.91 ± 0.11, and 0.90 ± 0.12 at 1, 2, 3, and 5 years postoperatively, respectively. No significant rotation was reported in any eye during follow-up.
The current study suggests that use of this trifocal toric IOL in eyes with high amounts of corneal astigmatism provides accurate refractive outcomes with good distance visual acuity. .
分析高度角膜散光患者白内障手术后植入三焦点散光人工晶状体(IOL)的屈光和视觉结果。
本研究共评估了 21 名患者的 29 只眼,这些患者均接受了三焦点散光 IOL(FineVision PODFT;PhysIOL)植入术。所有病例均行飞秒激光白内障超声乳化术及术中像差测量。所有使用的 IOL 柱镜度数均为 3.75 屈光度(D)或以上。主要观察指标为屈光误差和矫正远视力(CDVA)及未矫正远视力(UDVA)值。在 5 年的随访期间对眼睛进行评估。
术后 1、2、3、5 年,分别有 96.30%、100%、95.83%和 89.47%的眼在±1.00 D 以内;此外,术后 1、2、3、5 年,分别有 92.31%、86.36%、82.61%和 84.21%的眼屈光度柱值在±1.00 D 以内。在整个随访期间,81.48%至 91.30%的眼显示 CDVA 达到 20/25 或更好。单眼 Snellen 十进制 CDVA 平均值分别为术后 1、2、3、5 年的 0.90±0.12、0.90±0.11、0.91±0.11 和 0.90±0.12。随访期间无眼发生显著旋转。
本研究表明,在高度角膜散光眼中使用这种三焦点散光 IOL 可提供准确的屈光结果和良好的远视力。
