Following surgery, all patients received their ultraviolet (UV) light treatments at a separate open-access facility through a co-managed arrangement. Uncorrected distance visual acuity (UDVA), spherical equivalent (SE), and residual cylinder for eyes with an emmetropic refractive target were the primary outcome measures as documented at the patient’s final, stable, refractive postoperative exam.Results: Thirty-three patients (34 eyes) with a history of laser refractive surgery were included in the study and implanted with the second-generation LAL with a postoperative emmetropic refractive target. Twenty-eight (82.4%) saw 20/20 or better and 9 (26.5%) saw 20/15 or better. The mean SE was 0.01 ± 0.31 D and 33 (97.1%) were within ± 0.50 D SE of plano. The mean residual cylinder was − 0.28 ± 0.32 D and 30 (88.2%) were within ± 0.50 D.Conclusion: Use of the second-generation LAL was efficacious in cataract surgical patients with a history of LASIK and/or PRK using a co-managed, open-access methodology.Keywords: ActivShieldTM, light adjustable lens, LAL, cataract surgery, refractive surgery, LASIK, PRK
