To evaluate visual and refractive outcomes, as well as patient satisfaction after bilateral implantation of an enhanced monofocal intraocular lens (IOL) with emmetropia as a target refraction.
San Carlos Hospital, Madrid, Spain.
Prospective, monocentric, noncomparative study.
Adults 21 years or older suitable for cataract surgery and with corneal astigmatism <1.50 diopters (D) were bilaterally implanted with the RayOne EMV IOL and followed up for 3 months. Outcomes measures included refraction, monocular and binocular uncorrected distance visual acuity, corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity, distance-corrected intermediate visual acuity (DCIVA), and defocus curve, aberrometry, and satisfaction. Visual symptoms were assessed using the CatQuest-9SF questionnaire.
50 eyes of 25 patients were included. At month 3, the mean manifest spherical equivalent was -0.39 ± 0.28 D, with all eyes within 1.00 D. Binocularly, uncorrected, at distance, 68% of patients could read ≤0.0 logMAR and 95% ≤0.2 logMAR; at intermediate 59% of patients could read ≤0.1 and 100% ≤0.2 logMAR. Mean monocular CDVA was -0.03 ± 0.06 logMAR and mean monocular DCIVA was 0.28 ± 0.07 logMAR. Binocular defocus curve demonstrated a visual acuity ≤0.2 logMAR over a 2 D range from +1.00 D to -1.25 D. Satisfaction was good in 96% of patients.
Bilateral implantation of an enhanced monofocal IOL with emmetropia as a target provided excellent binocular CDVA and good DCIVA, with a high level of satisfaction.
评估双眼植入具有正视目标屈光度数的增强型单焦点人工晶状体（IOL）后的视力和屈光结果以及患者满意度。
西班牙马德里 San Carlos 医院。
前瞻性、单中心、非对照研究。
适合白内障手术且角膜散光<1.50 屈光度（D）的 21 岁及以上成年人，双眼植入 RayOne EMV IOL 并随访 3 个月。主要评估指标包括屈光度、单眼和双眼未矫正远视力、矫正远视力（CDVA）、未矫正中间视力、距离矫正中间视力（DCIVA）、散光度和患者满意度。使用 CatQuest-9SF 问卷评估视觉症状。
纳入 25 例患者的 50 只眼。术后 3 个月，平均等效球镜为-0.39 ± 0.28 D，所有眼均在 1.00 D 以内。双眼远距时，68%的患者未矫正视力可达到≤0.0 logMAR，95%的患者可达到≤0.2 logMAR；59%的患者中间距离视力可达到≤0.1，100%的患者可达到≤0.2 logMAR。平均单眼 CDVA 为-0.03 ± 0.06 logMAR，平均单眼 DCIVA 为 0.28 ± 0.07 logMAR。双眼散光度曲线显示，+1.00 D 至-1.25 D 范围内有 2 D 视差值时，视力可达到≤0.2 logMAR。96%的患者对结果表示满意。
植入具有正视目标屈光度数的增强型单焦点 IOL 可获得良好的双眼 CDVA 和 DCIVA，满意度高。
