Comparison of Visual Outcomes of Extended Depth of Focus Lenses in Patients With and Without Previous Laser Refractive Surgery

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.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.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).The data suggest that extended depth of focus lens implantation can have successful results for patients with prior laser refractive surgery.
