Abstract
Purpose: To determine the clinical outcomes after exchange of diffractive multifocal intraocular lenses (IOLs) with monofocal IOLs for patients who complained of dysphotopsia after cataract surgery.Methods: We exchanged the IOLs of patients who visited our clinic complaining that dysphotopsia had not improved after they underwent phacoemulsification and diffractive multifocal IOL implants in local eye clinics. We evaluated the corrected distance visual acuity (CDVA) before and after operation, the type of preoperative dysphotopsia, postoperative dysphotopsia status, patient satisfaction, and all complications.Results: We enrolled 35 eyes of 27 patients and observed them for 5.7 ± 3.6 months. After 1 month, the CDVA significantly (p < 0.001) improved from 0.131 ± 0.131 logarithm of the minimal angle resolution (logMAR) preoperatively to 0.0328 ± 0.0900 logMAR postoperatively. Patient satisfaction graded on a scale from 1 (very dissatisfied) to 5 (excellent) significantly (p < 0.001) increased from 1.17 ± 0.382 preoperatively to 4.09 ± 0.818 postoperatively. No vision-threatening complications developed. Postoperative cystoid macular edema developed in one eye but resolved after intravitreal bevacizumab (Avastin®, Genetech, Inc, San Francisco, CA, USA) injections.Conclusions: IOL exchange surgery relatively safely improves the vision of patients suffering from dysphotopsia attributable to the characteristics of diffractive multifocal IOLs.
目的:探讨单焦人工晶状体与衍射多焦人工晶状体置换后的临床效果。方法:对在当地眼科诊所行超声乳化术和衍射多焦人工晶体植入术后视力不良未得到改善的患者进行人工晶体置换。我们评估术前、术后矫正距离视力(CDVA)、术前移位移位类型、术后移位移位情况、患者满意度及所有并发症。结果:纳入27例患者35只眼,观察5.7±3.6个月。1个月后,CDVA显著(<i>p</i>& lt;最小角度分辨率(logMAR)由术前的0.131±0.131对数提高到术后的0.0328±0.0900对数。患者满意度从1(非常不满意)到5(极好)显著(<i>p</i>& lt;0.001),由术前的1.17±0.382增至术后的4.09±0.818。没有出现威胁视力的并发症。术后单眼出现囊样黄斑水肿,但玻璃体内注射贝伐单抗(Avastin<sup>®</sup>, Genetech, Inc, San Francisco, CA, USA)后消退。结论:由于衍射型多焦IOL的特点,人工晶状体置换术可以相对安全地改善患者的视力。
