Tonotopic and Default Frequency Fitting for Music Perception in Cochlear Implant Recipients: A Randomized Clinical Trial.

Importance: Cochlear implants are an effective technique for enhancing speech perception abilities in quiet environments for people with severe to profound deafness. Nevertheless, complex sound signals perception, such as music perception, remains challenging for cochlear implant users.

Objective: To assess the benefit of a tonotopic map on music perception in new cochlear implant users.

Efficacy and safety of intraocular folding sutureless scleral fixating lens versus iris-claw intraocular lens implantation.

Purpose: To compare the refractive outcomes of sutureless scleral-fixated Carlevale® intraocular lenses versus Artisan® iris-claw-fixated lenses in terms of surgically induced astigmatism.

Setting: We included patients from the Quinze-Vingts National Ophthalmology Hospital, Paris, from August 2020 to December 2020.

Design: This was a single-center retrospective study.

Assessing the correlation between swept-source optical coherence tomography lens density pattern analysis and best-corrected visual acuity in patients with cataracts.

Objective: To assess linear correlation between swept-source optical coherence tomography (SS-OCT) lens density variation and patients' best-corrected visual acuity (BCVA).

Methods And Analysis: Linear densitometry was performed on horizontal lens images from 518 eyes, obtained using SS-OCT. All densities from the anterior to the posterior side of the cataract were exported for detailed analysis.

An algorithm in ophthalmic emergencies to evaluate the necessity of physical consultation during COVID-19 lockdown in Paris: Experience of the first 100 patients.

Purpose: This study aimed to evaluate the ability of a freely accessible internet algorithm to correctly identify the need for emergency ophthalmologic consultation for correct diagnosis and management.

Method: This retrospective observational cohort study was based on the first 100 patients who requested recommendations on the necessity of breaking the lockdown for emergency ophthalmology consultation during the period from March to May 2020.

Results: Ninety-one patients completed questionnaires.
