Abstract: Purpose: To evaluate patient satisfaction and visual outcomes with extended depth of focus (EDOF) intraocular lens (IOL) implantation in post myopic refractive surgery patients with high corneal spherical aberrations. Methods: This was a non-interventional, observational, ambispective, bilateral, single center multi-surgeon study. Patients had history of myopic LASIK or PRK, and relatively high corneal spherical aberrations, and were bilaterally implanted with Vivity or Vivity toric EDOF IOLs targeting emmetropia. Endpoints included monocular and binocular uncorrected and distance corrected visual acuities at distance (UDVA, CDVA), intermediate (UIVA, DCIVA; 66cm), and near (UNVA, DCNVA; 40cm), binocular defocus curve, and patient satisfaction (IOLSAT) and visual disturbance (QUVID) questionnaires. Results: A total of 20 subjects (40 eyes) completed the study. Mean binocular UDVA, UIVA, and UNVA were 0.02 ± 0.16 logMAR, 0.14 ± 0.13 logMAR, and 0.24 ± 0.14 logMAR, respectively. The percentages of eyes with mean residual spherical equivalent and residual astigmatism ≤0.50 D were 95% (38/40) and 98% (39/40), respectively. On the QUVID questionnaire, 0% (0/20), 5% (1/20), and 0% (0/20) of patients reported being "Bothered quite a bit" or "Bothered very much" by halo, starbursts, or glare, respectively. On the IOLSAT, patient reported spectacle use was "Never" or "Rarely" in 90% (18/20), 75% (15/20), and 30% (6/20) of patients at distance, intermediate, and near, respectively. Conclusion: Results suggest good visual outcomes at distance, intermediate and functional near vision and high patient satisfaction with Vivity and Vivity toric IOL implantation in post myopic refractive surgery patients with high corneal spherical aberrations.
