PURPOSE To compare visual outcomes of eyes with and without previous laser refractive surgery that received an extended depth of focus intraocular lens during cataract surgery. METHODS This was a retrospective review of all eyes implanted with an extended depth of focus intraocular lens by two surgeons. Preoperative demographic and eye examination information were collected, as well as postoperative refraction, uncorrected distance visual acuity, and Visual Function Index (VF-14) questionnaire responses. Medical records were reviewed postoperatively to collect the number of patients who required a refractive touch-up or lens exchange. RESULTS Most patient eyes (187 of 215, 87%) had no prior refractive surgery, and there was no significant difference in preoperative characteristics between this group and the 28 eyes that did have previous laser refractive surgery. Postoperatively, most patients had a refractive error within ±0.50 diopters (D) (79% without vs 77% with previous laser refractive surgery, P = .40). Although more patients in the group without previous laser refractive surgery achieved 20/20 uncorrected distance visual acuity (UDVA) (56.8% versus 28.6%, P = .01), the majority in both groups achieved 20/25 or better UDVA (79.5% versus 85.7% for without versus with previous laser refractive surgery, P = .42). Postoperative subjective visual function score was also similar between the two groups as measured by the VF-14 questionnaire (86.9 vs 79.4, P = .15). Few patients required refractive surgery enhancement in either group (9 of 187 (4.8%) versus 1 of 28 (3.6%) for without versus with previous laser refractive surgery, P = .77). CONCLUSIONS The data suggest that extended depth of focus lens implantation can have successful results for patients with prior laser refractive surgery. [J Refract Surg. 2020;36(1):28-33.].

有或没有先前激光屈光手术的患者聚焦镜扩大深度的视觉结果比较。

目的比较在白内障手术期间接受和未接受过深度聚焦人工晶状体的激光屈光手术的眼睛的视觉效果。方法这是两名外科医生对植入了深度聚焦人工晶状体的所有眼睛进行的回顾性研究。收集术前人口统计学和眼科检查信息，以及术后屈光度，未矫正的远视力和视觉功能指数（VF-14）问卷。术后检查病历，以收集需要屈光矫正或晶状体更换的患者人数。结果大多数患者的眼睛（215眼中的187眼，占87％）没有进行过屈光手术 该组与之前接受过激光屈光手术的28只眼的术前特征无显着差异。术后，大多数患者的屈光不正在±0.50屈光度（D）以内（无激光屈光手术的有79％，无屈光手术的有77％，P = .40）。尽管该组中没有进行过激光屈光手术的患者中有20/20的未矫正远视力（UDVA）（56.8％比28.6％，P = .01），但两组中的大多数都达到了20/25或更好的UDVA（79.5％）与未进行激光屈光手术的患者相比，无视者为85.7％，P = 0.42）。两组患者的术后主观视觉功能评分也相似（通过VF-14问卷调查得出）（86.9 vs 79.4，P = .15）。两组中很少有患者需要进行屈光手术增强治疗（187个中的9个（4。8％）与未进行激光屈光手术的28人中有1人（3.6％）相比（28％）（P = 0.77）。结论数据表明，对于先前进行过激光屈光手术的患者，扩大聚焦透镜植入深度可以取得成功的结果。[J Refract Surg。2020; 36（1）：28-33。]。
