To determine the visual performance and patient reported outcomes after bilateral implantation of an enhanced monofocal intraocular lens (IOL) (RayOne EMV RAO200E) targeted for emmetropia or modest monovision.
This was a prospective, single-centre, comparative, interventional study. Patients were divided into two groups and targeted for bilateral emmetropia or modest monovision (-1.50 D in the near eye). Manifest refraction, monocular uncorrected and corrected distance visual acuity (UDVA and CDVA), uncorrected and distance-corrected intermediate visual acuity (UIVA and DCIVA), uncorrected and distance-corrected near visual acuity (UNVA and DCNVA), and monocular and binocular defocus curves under photopic and mesopic conditions were measured at 1-month post-surgery. The Catquest 9-SF questionnaire was administered to assess patient reported visual outcomes and quality of life.
60 patients were enrolled. For the emmetropia group (n = 30), the mean logMAR UDVA, UIVA and UNVA were 0.16±0.13, 0.35±0.12 and 0.50±0.15. In the monovision group (n = 30), the values for the distance eyes were 0.13±0.11, 0.40±0.11 and 0.56±0.13; and for the near eyes 0.41±0.21, 0.27±0.16 and 0.34±0.13. Binocular defocus curves showed similar distance visual acuity but better visual acuity in the monovision group from -1.00 D to -4.00 D and -1.00 D to -3.50 D defocus under photopic and mesopic conditions respectively (p < 0.05). The defocus range (logMAR 0.2 or better) was 1.3 D for the bilateral emmetropia group and 2.5 D for the monovision group. 90% (emmetropia group) and 96% (monovision group) of patients were very or fairly satisfied with their vision, with the monovision group reporting better performance for intermediate and near tasks.
Patients targeted for bilateral emmetropia achieved good functional intermediate vision, while those with modest monovision experienced enhanced intermediate and near vision. Overall, patients reported high satisfaction and good visual performance when implanted with the enhanced monofocal IOL.
确定双侧植入针对正视或适度单眼视力的增强型单焦点人工晶状体（IOL）（RayOne EMV RAO200E）后的视觉表现和患者报告的结果。
这是一项前瞻性、单中心、比较性、干预性研究。患者分为两组，目标是双侧正视或适度单眼视力（近眼为-1.50 D）。在术后1个月测量显验光、单眼未矫正和矫正远视力（UDVA和CDVA）、未矫正和远矫正中视力（UIVA和DCIVA）、未矫正和远矫正近视力（UNVA和DCNVA），以及明视和 mesopic 条件下的单眼和双眼散焦曲线。使用Catquest 9-SF问卷评估患者报告的视觉结果和生活质量。
共纳入60例患者。正视组（n = 30）的平均logMAR UDVA、UIVA和UNVA分别为0.16±0.13、0.35±0.12和0.50±0.15。在单眼视力组（n = 30）中，远眼的值分别为0.13±0.11、0.40±0.11和0.56±0.13；近眼的值分别为0.41±0.21、0.27±0.16和0.34±0.13。双眼散焦曲线显示远视力相似，但单眼视力组在明视和 mesopic 条件下分别从-1.00 D到-4.00 D和-1.00 D到-3.50 D散焦时视力更好（p < 0.05）。双侧正视组的散焦范围（logMAR 0.2或更好）为1.3 D，单眼视力组为2.5 D。90%（正视组）和96%（单眼视力组）的患者对其视力非常或相当满意，单眼视力组在中距离和近距离任务中表现更好。
目标为双侧正视的患者获得了良好的功能性中视力，而适度单眼视力者的中视力和近视力得到增强。总体而言，植入增强型单焦点IOL的患者报告了高满意度和良好的视觉表现。
