Visual Performance of Two Designs of Myopia Management Soft Contact Lenses Compared with a Monofocal One in Young Adults.

Purpose: To compare the visual performance of two distinct types of soft contact lenses (CL) aimed at slowing down myopia progression with the performance of a monofocal soft CL.

Methods: In a prospective double-masked, crossover trial, 18 myopic adults (aged 18-30 years old) were fitted in a randomized order with three types of disposable CL: MiSight (dual-focus), Mylo (extended depth of focus -EDOF-), and Clariti (single distance vision). Measurements were taken after wearing the CL for five days with five days off in between at two different optometry centers.

Anterior segment optical coherence tomography angiography to evaluate the peripheral fitting of scleral contact lenses.

Purpose: The aim of this study was to show the potential applicability of optical coherence tomography angiography (OCTA) for the evaluation of the peripheral fitting of fully scleral contact lenses.

Methods: A pilot study was proposed fitting three different scleral contact lenses (Irregular Corneal Design [ICD]) with different sagittal heights (4200, 4800, and 5600 mm) in a healthy volunteer of 27 years old. We evaluated by means of optical coherence tomography (OCT, DRI Triton) the apical clearance achieved with each of the three lenses fitted.
