A Retrospective Study: Comparative Visual Performance of Two Non-Diffractive Extended Depth-of-Focus Intraocular Lenses: TECNIS PureSee versus Clareon Vivity

Purpose: To compare postoperative visual performance between two non-diffractive, extended depth-of-focus (EDoF) intraocular lenses (IOLs) — TECNIS PureSee and Clareon Vivity — by evaluating visual acuity, contrast sensitivity, and patient-reported outcomes. Methods: In this retrospective comparative study, 102 eyes (51 per group) received either the PureSee or Vivity IOL. Visual acuity at various distances, defocus curves, and contrast sensitivity under photopic and mesopic conditions were assessed at 2 months postoperatively. Patient satisfaction and visual disturbances were also evaluated. Results: Both the PureSee and Vivity IOL demonstrated comparable visual acuity at far and near distances, while the Vivity showing significantly better visual acuity at intermediate distances ( P = 0.045). Contrast sensitivity was significantly higher in the PureSee group at higher spatial frequencies ( P = 0.038). Patient satisfaction and spectacle independence were high and comparable in both groups. The Vivity group showed a trend toward fewer reports of glare and halo. Conclusion: The Vivity IOL performed better at intermediate distances with fewer photic phenomena when compared with the PureSee IOL. The differences between these two EDoF IOLs may help in lens selection based on patient’s visual demands and lifestyle.
