Clinical Performance of an Extended Range of Vision Intraocular Lens After LASIK.

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

The wavefront-shaping EDOF IOL evaluated provides efficacious distance, intermediate, and near visual restoration in eyes with previous LASIK, with minimal photic phenomena associated. .
