To evaluate the outcomes following bilateral ERV intraocular lens implantation with micromonovision.
25 subjects underwent bilateral Tecnis Symfony IOL implantation with micromonovision. The dominant eye was targeted for emmetropia and the nondominant eye for myopia of -0.75 D. Uncorrected and corrected distance (UDVA, CDVA), intermediate (UIVA, CIVA), and near visual acuity (UNVA, DCNVA); reading performance; defocus curve; and contrast sensitivity were studied. Follow-ups were conducted at 1 week and 1 and 6 months postoperatively.
At 6 months postoperatively, the mean binocular UDVA, CDVA, UNVA, and DCNVA were -0.036 ± 0.09, -0.108 ± 0.07, 0.152 ± 0.11, and 0.216 ± 0.10 logMAR, respectively. Binocular UIVA and DCIVA were 0.048 ± 0.09 and 0.104 ± 0.08 logMAR, respectively, at 60 cm and -0.044 ± 0.09 and 0.012 ± 0.09 logMAR, respectively, at 80 cm. All patients had ≥0.2 logMAR UDVA and UNVA. Reading acuity and reading speeds showed improvement over time. Between defocus range of -2.50 and +1.00 D, the visual acuity remained ≥0.2 logMAR. Contrast sensitivity scores were within the normal range. 4 patients used reading glasses for very fine print.
Bilateral ERV IOL implantation leads to excellent outcomes for far and intermediate vision, satisfactory outcomes for near vision, and good tolerance to micromonovision at the end of the 6 months. This trial is registered with CTRI/2015/10/006246.
评估采用微单眼视力的双侧扩展型折射性人工晶状体（ERV）植入术后的效果。
25名受试者接受了双侧Tecnis Symfony人工晶状体植入术并采用微单眼视力。优势眼目标为正视，非优势眼目标为-0.75 D的近视。研究了未矫正和矫正的远视力（UDVA、CDVA）、中视力（UIVA、CIVA）和近视力（UNVA、DCNVA）；阅读表现；散焦曲线；以及对比敏感度。在术后1周、1个月和6个月进行随访。
术后6个月时，双眼平均UDVA、CDVA、UNVA和DCNVA分别为-0.036±0.09、-0.108±0.07、0.152±0.11和0.216±0.10 logMAR。双眼UIVA和DCIVA在60 cm处分别为0.048±0.09和0.104±0.08 logMAR，在80 cm处分别为-0.044±0.09和0.012±0.09 logMAR。所有患者的UDVA和UNVA均≥0.2 logMAR。阅读视力和阅读速度随时间有所改善。在-2.50至+1.00 D的散焦范围内，视力保持≥0.2 logMAR。对比敏感度评分在正常范围内。4名患者使用阅读眼镜来阅读非常小的字体。
双侧ERV人工晶状体植入在6个月末时可实现远视力和中视力的良好效果、近视力的满意效果以及对微单眼视力的良好耐受性。本试验已在CTRI/2015/10/006246注册。
