PURPOSE: Dissatisfaction with the implanted IOL due to undesirable photic phenomena, contrast sensitivity issues, or inadequate visual performance, etc, may necessitate IOL exchange surgery with another IOL. enVista Envy is a full visual range (FVR) IOL designed to enhance the range of vision, maintain good contrast, and induce minimal dysphotopsia. The purpose of this retrospective study was to evaluate visual performance and patient-reported outcomes following IOL exchange surgery with a FVR IOL.

METHODS: Case records of 23 patients (32 eyes) who were dissatisfied with previously implanted IOLs, such as Clearview 3, Tecnis Odyssey, Alcon PanOptix, Light Adjustable Lens (LAL), or other monofocal IOLs, and underwent IOL exchange with the enVista Envy FVR IOL were reviewed. Outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), manifest refraction spherical equivalent (MRSE), and subjective patient experience at 1-month follow-up following the IOL exchange.

RESULTS: Following IOL exchange with the FVR IOL, the mean UDVA was 0.12 ± 0.15 logMAR, with 84.4% of eyes achieving 20/30 or better. The mean CDVA was 0.05 ± 0.12 logMAR, with 93.8% of eyes achieving 20/30 or better. The mean UNVA was -0.05 ± 0.08 logMAR, and all (100%) eyes achieved 20/30 or better. Mean MRSE was -0.08 ± 0.43 D. Patients exchanged from ClearView 3 to Envy reported resolution of halos and haziness, fewer artifacts, and less shadowing, and improvement in overall vision, especially near vision, postoperatively. Patients exchanged from Odyssey experienced fewer halos, better intermediate vision, and improved peripheral vision. Patients exchanged from LAL, or other monofocal IOL reported improvement with reading and computer work. One PanOptix IOL-implanted eye that experienced constant halos also reported improvement in subjective vision following exchange.

CONCLUSIONS: IOL exchange to enVista Envy FVR IOL yielded good distance and near vision outcomes along with high patient satisfaction. Visual disturbances such as halos, starbursts, glare, hazy vision, and peripheral vision blur, reported with previously implanted IOLs, resolved/reduced following IOL exchange to enVista Envy IOL.
