To evaluate the astigmatism tolerance and the visual outcomes after implantation of a premium intraocular lens (IOL) with a continuous transitional focus (Precizon Presbyopic; Ophtec BV) in pseudophakic presbyopia correction.
This prospective study enrolled 20 patients (40 eyes) after bilateral phacoemulsification and IOL implantation. Corrected and uncorrected visual acuities at 4 m and 80, 67, and 40 cm (CDVA, UDVA, DCI80VA, UI80VA, DCI67VA, UI67VA, DCNVA, and UNVA), astigmatic and spheric defocus curve, mean reading speed (MRS), critical print size (CPS), contrast sensitivity, optical aberrations (modulation transfer function [MTF] cut-off, Strehl ratio, and higher order aberration root mean square [HOA RMS]), objective halometry, and National Eye Institute Refractive Error Quality of Life Instrument 42 [NEI RQL-42] questionnaire were evaluated 3 months after surgery.
Astigmatic defocus curves revealed a tolerance up to -1.00 and +0.75 diopters (D) for with-the-rule astigmatism, and up to -1.00 and +1.00 D for against-the-rule astigmatism. Binocular spheric defocus curve showed that the mean visual acuity was greater than 0.15 logMAR from 1.00 to -1.00 D. MRS, CPS, MTF cut-off, Strehl ratio, and HOA RMS were 116.97 ± 21.94 words/min, 0.45 ± 0.06 logRDA, 20.03 ± 4.86 cycles/degree, 0.11 ± 0.07, and 0.28 ± 0.09, respectively. Contrast sensitivity was within the normal range for all tested light conditions. The NEI RQL-42 evidenced high subjective satisfaction for all subscales, especially for far vision, activity limitations, dependence on correction, suboptimal correction, appearance, and satisfaction with correction.
The Precizon Presbyopic IOL allows good astigmatism tolerance and both objective and subjective high quality of vision. .
评估在人工晶状体性老视矫正中植入具有连续过渡焦点的高端人工晶状体（Precizon Presbyopic；Ophtec BV）后的散光耐受性和视觉效果。
这项前瞻性研究纳入了20例（40只眼）接受双侧超声乳化白内障吸除术和人工晶状体植入术的患者。在术后3个月评估4米及80、67和40厘米处的矫正和未矫正视力（CDVA、UDVA、DCI80VA、UI80VA、DCI67VA、UI67VA、DCNVA和UNVA）、散光和球镜离焦曲线、平均阅读速度（MRS）、临界印刷字体大小（CPS）、对比敏感度、光学像差（调制传递函数[MTF]截止值、斯特列尔比和高阶像差均方根[HOA RMS]）、客观眩光测量以及美国国立眼科研究所屈光不正生活质量量表42[NEI RQL - 42]问卷。
散光离焦曲线显示顺规散光的耐受性高达 - 1.00和 + 0.75屈光度（D），逆规散光的耐受性高达 - 1.00和 + 1.00 D。双眼球镜离焦曲线表明，从1.00到 - 1.00 D，平均视力大于0.15 logMAR。MRS、CPS、MTF截止值、斯特列尔比和HOA RMS分别为116.97±21.94字/分钟、0.45±0.06 logRDA、20.03±4.86周期/度、0.11±0.07和0.28±0.09。在所有测试光照条件下，对比敏感度均在正常范围内。NEI RQL - 42表明所有子量表的主观满意度都很高，尤其是在远视力、活动受限、对矫正的依赖、矫正不足、外观以及对矫正的满意度方面。
Precizon Presbyopic人工晶状体具有良好的散光耐受性，能实现客观和主观的高质量视觉效果。
