Achroma intraocular lens7/21/2023 ![]() To improve the postoperative visual quality, IOLs with lower chromatic aberration should be selected for patients with short axial lengths. With higher diopters of IOLs, the central thickness increased accordingly, which could have created increased chromatic aberration and decreased the retinal image quality. The MTF values were also found to be increased with the increase in IOL diopter. The MTF values of each IOL eye model were significantly lower than the MTF values of the Liou-Brennan eye models when measured at 555 nm of monochromatic light and at 470 to 650 nm of polychromatic light. The influences of chromatic aberration on MTF values decreased with the increase in IOL diopter when the spatial frequency was ≤12 c/d, while increased effects were observed when the spatial frequency was ≥15 c/d. MTF values, measured at 555 nm of monochromatic light under each spatial frequency, were significantly higher than the values measured at 470 to 650 nm of polychromatic light. Spherical IOLs with different diopters (AR40e, AMO Company, USA) were implanted modulation transfer function (MTF) values at 3 mm of pupil diameter and from 0 to out-of-focus blur were collected and graphed. Call (561) 747-7777 to book an appointment.In this study, the effects of intraocular lenses (IOLs) with different diopters (D) on chromatic aberration were investigated in human eye models, and the influences of the central thickness of IOLs on chromatic aberration were compared.Ī Liou-Brennan-based IOL eye model was constructed using ZEMAX optical design software. Benaim helps cataract patients find the right lens for their vision needs. Not sure which type of intraocular lens to choose? Dr. Modeled after the human eye, Crystalens® is the first FDA-approved accommodating intraocular lens. ![]() This also provides significant advantages in addressing intermediate vision. By allowing the eye to focus on objects across a broad range of distances, accommodating intraocular lenses reduce or eliminate dependence on glasses or contacts.
