Abstract
PURPOSE: To evaluate the clinical and patient-reported outcomes (PROMs) of cataract surgery with implantation of a wavefront-shaping extended depth of focus (EDOF) intraocular lens (IOL) in eyes with previous laser in situ keratomileusis (LASIK) for myopia correction. METHODS: This prospective observational study enrolled 50 eyes with previous LASIK from 25 patients (age: 46 to 70 years) who underwent cataract surgery with implantation of the AcrySof IQ Vivity IOL (Alcon Laboratories, Inc). Visual and refractive outcomes were evaluated during a 3-month follow-up. PROMs were evaluated with the Intraocular Lens Satisfaction (IOLSAT; Alcon Vision, LLC) (general satisfaction), Catquest-9SF (difficulty in doing vision-related activities), and Questionnaire for Visual Disturbances (QUVID; Alcon Vision, LLC) (photic phenomena) questionnaires. RESULTS: Mean 3-month postoperative binocular uncorrected distance, intermediate, and near visual acuities were 0.02 ± 0.11, -0.02 ± 0.09, and 0.14 ± 0.13 logarithm of the minimum angle of resolution (logMAR), respectively. Mean binocular distance-corrected intermediate and near visual acuities were 0.05 ± 0.11 and 0.32 ± 0.14 logMAR, respectively. All eyes had a postoperative spherical equivalent within ±0.75 diopters (D). The mean defocus curve showed visual acuity values better than 0.20 logMAR for defocus levels from +0.50 to -1.50 D. Most patients (92.0%) confirmed that they had no vision-related difficulties limiting their normal daily life. Perception of starbursts, halos, glare, hazy vision, blurry vision, and double vision was referred by 24%, 24%, 28%, 28%, 8%, and 4% of patients, respectively. Most of symptoms were described as mild and not or a little bothersome. CONCLUSIONS: .
