To evaluate the tolerance for refractive errors and visual outcomes of extended depth of focus intraocular lens (EDOF IOLs) in patients with previous corneal refractive surgery for myopia.
Patients from Aier Eye Hospital of Wuhan University with previous myopia excimer laser correction underwent cataract surgery and implantation of an EDOF IOL. The follow-up period was three months. The uncorrected distance, intermediate, and near visual acuities (UDVA, UIVA, UNVA), corrected distance visual acuity (CDVA), spherical equivalent (SE), defocus curve, optical quality, including modulation transfer functions (MTF) and Strehl ratio (SR), National Eye Institute Visual Functioning Questionnaire-14 for Chinese people (VF-14-CN), spectacle independence, and dysphotopsia were assessed.
At the final visit, UDVA, CDVA, UIVA, and UNVA (LogMAR) were 0.06 ± 0.09, 0.01 ± 0.06, 0.11 ± 0.08, 0.20 ± 0.10, respectively. The mean spherical equivalent (SE) was - 0.57 ± 0.58D, sphere and cylinder were - 0.24 ± 0.60D, - 0.70 ± 0.58D respectively. No statistical difference in UDVA between eyes with SE in ± 0.50 D and in ± 1.0 D (p > 0.05). Corneal astigmatism > 1.00D has no significant effect on postoperative visual acuity (p > 0.05). The defocus curve showed that visual acuity could reach 0.2 in the refractive range of + 0.50D ~ - 1.50D. SR and MTF values were all higher than before the surgery. In bilateral implantation patients, the VF-14-CN questionnaire score and visual quality were quite excellent.
The EDOF IOL have a certain tolerance for refractive errors and corneal astigmatism, and it's recommended for patients with prior myopia excimer laser surgery to achieve satisfactory visual performance.
评估对既往近视准分子激光矫正术后患者植入扩展景深人工晶状体（EDOF IOL）的屈光误差和视觉结果的耐受性。
武汉大学爱尔眼科医院既往接受过近视准分子激光矫正的患者接受白内障手术并植入 EDOF IOL。随访时间为 3 个月。评估未矫正远视力（UDVA）、未矫正中间视力（UIVA）、未矫正近视力（UNVA）、矫正远视力（CDVA）、等效球镜（SE）、散光度、离焦曲线、光学质量（包括调制传递函数（MTF）和斯特列尔比（SR））、中国人国家眼科研究所视觉功能问卷-14 （VF-14-CN）、眼镜独立性和光不适。
末次随访时，UDVA、CDVA、UIVA 和 UNVA（LogMAR）分别为 0.06±0.09、0.01±0.06、0.11±0.08、0.20±0.10。平均等效球镜（SE）为−0.57±0.58D，球镜和柱镜分别为−0.24±0.60D、−0.70±0.58D。SE 在±0.50D 和±1.0D 的眼之间的 UDVA 无统计学差异（p>0.05）。角膜散光>1.00D 对术后视力无显著影响（p>0.05）。离焦曲线显示，在+0.50D~−1.50D 的屈光范围内，视力可达到 0.2。SR 和 MTF 值均高于术前。在双侧植入患者中，VF-14-CN 问卷评分和视觉质量均非常优秀。
EDOF IOL 对屈光误差和角膜散光有一定的耐受性，建议既往接受过近视准分子激光手术的患者植入以获得满意的视觉效果。
