Purpose: To compare the performance of Tecnis Eyhance ICB00 with Tecnis PCB00 IOL for far, intermediate, and near vision, in patients after bilateral cataract surgery.
Settings: This study was done at Geneva University Hospitals.
Design: This is a retrospective study of 224 eyes that underwent cataract between May 2019 and June 2020.
Methods: Visual acuity was assessed from month 1 to 12 after surgery for distance, intermediate and near visual acuity, by the same optometrist, which was blind regarding the type of IOL. The patients answered to a quality of life questionnaire. Patients were excluded for: monocular surgery, macular disease, other IOL type, or inability to reach 20/20 visual acuity in both eyes without correction.
Results: One hundred and fifty-two eyes were excluded. Three groups were then analyzed: PCB00 group (38 eyes), ICB00 group (22 eyes), and mismatch group (12 eyes). Monocular visual acuities (CIVA, UNVA and CNVA, in logMAR) were higher in the ICB00 group than the PCB00 group (respectively 0.3 vs 0.4, p = 0.0033; 0.3 vs 0.4, p = 0.0408; 0.3 vs 0.4, p = 0.0039). Binocular visual acuities, CIVA and CNVA were higher in the ICB00 group than the PCB00 group (0.2 vs 0.4, p = 0.0061; 0.15 vs 0.3, p = 0.018). This mirrored the findings of the quality of life questionnaire. There was no significant difference between PCB00 and mismatch groups.
Conclusions: the Tecnis Eyhance was more effective for intermediate and near vision. The central defocus of the lens might help patients achieve spectacle independence and better quality of life.
