Comparison Of Visual Results Between Classic Monofocal Intraocular Lens (Iol) Zcb00 And Extended Vision Iol Icb00

To compare clinical visual outcomes between the monofocal TECNIS Eyhance IOL (Model ICB00) and a classical monofocal IOL (TECNIS, Model ZCB00) after cataract surgery. 

This double-blind, randomized controlled trial recruited patients diagnosed with bilateral cataracts with corneal astigmatism less than 1.50  diopters (D), axial length between 21 - 27 mm, and corneal power between 40D - 46D. Patients for bilateral phacoemulsification were randomly allocated (1:1) to receive an EDOF ICB00 or the ZCB00 monofocal lens. Near, intermediate, and far distance visual acuity were measured preoperative and 3 months after surgery. Patient satisfaction assessment with CatQuest-9SF and Quality of Vision (QoV) questionnaires were also compared. An appropriate unpaired t-test with 0,05% significance level was used. This trial was approved by an Institutional Ethics Committee and adheres to  Helsinki declaration.

Overall, 40 (80 eyes) finished follow-up so far. Eyhance IOL were implanted in 34 eyes, whereas TECNIS IOL were implanted in 46 eyes. Best corrected intermediate visual acuity at 66 cm was significantly (p < 0,05) improved by 1,2-line logarithm of the minimum angle of resolution in the Eyhance IOL group. Distance corrected vision was not different between groups, neither complication reports, CatQuest-9SF, nor QoV scores.

In patients undergoing cataract surgery, the enhanced monofocal Eyhance ICB00 provided better intermediate vision with identical distance vision and photic phenomena compared with a monofocal IOL.
