PURPOSE
To evaluate reading performance of a trifocal intra-ocular lens (IOL) at near and intermediate distances using the Salzburg Reading Desk.
SETTING
International Vision Correction Research Centre and David J. Apple Laboratory, University Eye Clinic, Heidelberg, Germany.
DESIGN
Prospective, nonrandomized clinical study.
METHODS
Follow-up examinations at a minimum of 3 months postoperatively included uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA)) intermediate as well as uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity. Uncorrected and distance-corrected reading acuity at 40 cm for near, 80 cm for intermediate distance, and at the patient's preferred near and intermediate distances were evaluated with the reading desk.
RESULTS
In this study, 22 eyes of 11 patients having cataract surgery with implantation of the trifocal Finevision IOL were evaluated. Postoperative monocular Snellen median values were 20/21.44 (range 20/52.61 to 20/14.49) for UDVA, 20/20.47 (range 20/38.11 to 20/16.64) for UIVA, and 20/26.39 (range 20/43.76 to 20/18.24) for UNVA. Subjective intermediate distance at the binocular uncorrected examination on the reading desk was 64.2 cm (range 51.9 to 80.0) with a reading acuity of 0.10 logMAR (range 0.32 to 0.00). Subjective near distance at the uncorrected binocular reading desk examination was 36.5 cm (30.8 to 41.2) with a near reading acuity of 0.06 logMAR (range 0.23 to -0.01). The preferred distances differed significantly from the fixed ones of 40 and 80 cm. The preferred intermediate distance was almost consistent, with the intermediate addition of 1.75 D corresponding to 57.1 cm.
CONCLUSION
The visual and reading function of the trifocal IOL was better at the patient's preferred near and intermediate distances.

目的
使用萨尔茨堡阅读桌评估三焦点人工晶状体（IOL）在近距和中距的阅读性能。
设置
国际视力矫正研究中心和德国海德堡大学眼科诊所大卫·J·苹果实验室。
设计
前瞻性、非随机临床研究。
方法
术后至少3个月的随访检查包括未矫正的（UDVA）和矫正的（CDVA）远视力、未矫正的（UIVA）和远矫正的（DCIVA）中视力以及未矫正的（UNVA）和远矫正的（DCNVA）近视力。使用阅读桌评估在40 cm处的近距、80 cm处的中距以及患者偏好的近距和中距下未矫正和远矫正的阅读视力。
结果
在本研究中，对11例接受白内障手术并植入三焦点Finevision IOL的患者的22只眼进行了评估。术后单眼Snellen中位数UDVA为20/21.44（范围20/52.61至20/14.49），UIVA为20/20.47（范围20/38.11至20/16.64），UNVA为20/26.39（范围20/43.76至20/18.24）。在阅读桌上进行双眼未矫正检查时，主观中距为64.2 cm（范围51.9至80.0），阅读视力为0.10 logMAR（范围0.32至0.00）。在未矫正的双眼阅读桌检查中，主观近距为36.5 cm（30.8至41.2），近阅读视力为0.06 logMAR（范围0.23至 -0.01）。偏好距离与40 cm和80 cm的固定距离有显著差异。偏好的中距几乎一致，附加1.75 D的中焦距相当于57.1 cm。
结论
三焦点IOL在患者偏好的近距和中距下视觉和阅读功能更佳。
