摘要

目的:评估双侧植入新型 Clareon® 人工晶体的患者术后迷你单视的视觉效果:研究在印度潘维尔的三级眼科医疗机构拉克斯米眼科研究所进行:设计:这是一项由研究者发起的前瞻性单中心纵向研究,共45名患者参加,目的是评估双侧植入Clareon ®人工晶体的患者的视觉效果:方法:研究对象包括角膜散光≤0.75 D、接受双侧白内障手术、假性角膜小单视并植入新型 Clareon® 人工晶体的患者。不包括术后显性屈光度大于±0.25 D,非显性屈光度为-0.75 D的患者。主要研究结果在 1 个月和 3 个月时进行评估,包括未矫正视力评估、散焦曲线和患者报告的眼镜使用情况:结果:3个月时的平均(标清)双眼距离矫正中间视力为0.22(0.09)LogMAR。3 个月时,54% 的患者享有 0.4 LogMAR 或更高的 BUCNVA。散焦曲线显示出良好的远中视力,从+0.50 D到-1.50 D的视力均大于0.2 LogMAR。我们发现术后3个月时主视眼的Q值与BCIVA呈正相关,但在统计学上并不显著。当中间视力接近 0 LogMAR 时,Q 值呈负值。术后 3 个月时,95% 的患者不需要戴眼镜看远和看中距离,73% 的患者在不戴眼镜的情况下看中距离视力也很舒适:结论:植入 Clareon® 单焦点人工晶体的迷你单眼手术可提供令人满意的整体中远距离视力,且近距离视力对眼镜的需求极低。

Evaluation of Intermediate Visual Outcomes in Eyes Implanted with Bilateral Advanced Monofocal Intraocular Lens Targeting for Mini-Monovision and Its Association with Age and Corneal Asphericity.

Purpose: To assess the visual outcomes in patients bilaterally implanted with novel Clareon® intraocular lens when targeting mini monovision post-operatively.

Setting: The study was conducted at Laxmi Eye Institute; it is a tertiary care eye institution in Panvel, India.

Design: This is an investigator initiated, prospective, single-centre longitudinal study of 45 patients to assess the visual outcomes in patients who were implanted with Clareon ® IOL bilaterally.

Methods: Patients with corneal astigmatism of ≤0.75 D who underwent bilateral cataract surgery with pseudophakic mini-monovision and implanted with novel Clareon® intraocular lens were included. Patients having post op manifest refraction >±0.25 D in the dominant eye and <-0.5 D or >-0.75 D in the non-dominant eye were excluded. The main study outcomes were assessed at 1 and 3 months; it included uncorrected visual acuities assessment, defocus curve, and patient reported spectacle use.

Results: The mean (SD) binocular distance corrected intermediate visual acuity at 3 months was 0.22 (0.09) LogMAR. At 3 months, 54% of patients enjoyed 0.4 LogMAR or better BUCNVA. The defocus curve showed good distance and intermediate visual acuity with >0.2 LogMAR vision from +0.50 D to -1.50 D. We found a positive correlation between the Q value of the dominant eye and the BCIVA at 3 months postoperatively, however it was not statistically significant. The Q value was more negative when the intermediate vision was closer to 0 LogMAR. Post operatively, at 3 months, 95% patients did not need glasses for distance and intermediate vision and 73% of patients were comfortable for intermediate vision without glasses all the time.

Conclusion: Mini-monovision with Clareon® monofocal IOL implantation can offer overall satisfactory vision for far and intermediate distances with minimal need for use of spectacles for near vision.
