ABSTRACT
Purpose: To demonstrate the results of ray tracing aberrometric measurements and optical function of recently introduced enhanced depth of focus intraocular lenses.
Methods: Lower and higher-order aberrations, refraction, distance and near visual acuity, and tear break-up time were measured at scotopic pupil size in 121 eyes of patients who received either the Vivity lens (Alcon AcrySof IQ Vivity) or the LuxSmart lens (Bausch + Lomb LuxSmartTM). Measurements were obtained using ray tracing aberrometry, with corneal placido topographic subtraction to delineate internal aberrations.
Results: The application of the Krefft algorithm to the empirical material for both types of extended depth of focus lenses allowed to determine the quality symbol by obtaining estimators of individual features of aberrations induced by each lens. The results of the comparison of the mean quality level coefficient showed no statistically significant difference between the lenses in terms of lens induced aberrations p=0.127 and total ocular aberrations without defocus p=0.288 and following defocus correction.
Conclusion: Both extended depth of focus intraocular lens models effectively achieved refractive targets for distance and near vision, with similar highorder aberrations.
