To report improved visual outcome after rotation of an asymmetrical multifocal intraocular lens (IOL).
Case report.
A 58-year-old patient underwent bilateral phacoemulsification with asymmetrical multifocal IOL implantation. Postoperative uncorrected distance visual acuity (UDVA) was 0.0 logMAR (20/20 Snellen) and uncorrected near visual acuity was 0.0 logMAR (20/20 Snellen) in both eyes. Quality of vision questionnaire scores for day and night were 5 and 7, respectively. The center of the multifocal IOL in the dominant eye was initially found to be 0.2 mm superotemporally displaced, increasing the percentage area of 'near-add' compared to 'distance-add' within the physiological pupil. Rotation of this IOL 120° clockwise greatly improved the IOL centration within the pupil center and resulted in an immediate improvement in UDVA to -0.1 logMAR (20/16 Snellen) and quality of vision questionnaire scores to 8 and 9, respectively.
Assessment of the centration of an asymmetrical multifocal IOL is important, particularly if there are dysphotoptic or other visual complaints. [J Refract Surg. 2016;32(7):494-496.].
报告非对称多焦点人工晶状体（IOL）旋转后视觉效果改善的情况。
病例报告。
一名58岁患者接受了双眼超声乳化联合非对称多焦点IOL植入术。术后双眼未矫正远视力（UDVA）均为0.0 logMAR（20/20 Snellen），未矫正近视力均为0.0 logMAR（20/20 Snellen）。日间和夜间视力质量问卷评分分别为5分和7分。优势眼的多焦点IOL中心最初被发现向上颞侧移位0.2 mm，与生理瞳孔内“远用附加”相比，“近用附加”的百分比面积增加。将该IOL顺时针旋转120°极大地改善了IOL在瞳孔中心的居中情况，并使UDVA立即提高到-0.1 logMAR（20/16 Snellen），视力质量问卷评分分别提高到8分和9分。
评估非对称多焦点IOL的居中情况很重要，特别是在存在眩光或其他视觉问题时。[《屈光手术杂志》。2016年；32(7):494 - 496。]
