This case-control study aimed to identify new risk factors associated with Unilateral or Highly Asymmetric Keratoconus (UHAKC). The results showed a significant association between UHAKC and the following factors: eye rubbing, either during the day or in the morning and especially when it was done on the ipsilateral side; an incorrect sleeping position, i.e., […]

Link to the paper   Rainbow glare (RG) is a rare optical side effect of femtosecond laser-assisted LASIK (FS-LASIK) where patients complain of immediate postoperative rainbow-like glares when exposed to a polychromatic light source such as artificial lights. The presumed hypothesis is that they are caused by a diffractive grating pattern of geometrically-aligned, regularly-spaced femtosecond […]

Here we present a synopsis of our study, where machine learning using wavefront data processed with a new polynomial decomposition basis is leading to accurate and precise prediction of spectacle correction.   The paper is available here: https://www.nature.com/articles/s41598-020-65417-y Optical wavefront sensing using aberrometry is an objective method that allows mathematical reconstruction and analysis of lower […]

Ce dossier paru récemment expose les avancées récentes dans la compréhension des mécanismes impliqués dans la genèse et l’évolution du kératocône et les résultats cliniques issus de la mise en pratique de ces concepts par notre équipe à l’Hôpital Fondation Rothschild. Vous y découvrirez comment les frottements oculaires initient et entretiennent un processus physiopathologique dont […]

Cette étude rapporte les complications enregistrées après insertion d’un implant d’iris pour changer la couleur des yeux. Seuls 5% des yeux n’avaient pas présenté de complications sévères au moment de cette enquête, alors que plus de 80% des implants devaient être retirés…   Lien vers le résumé de l’article: https://www.ncbi.nlm.nih.gov/pubmed/32050230 Version prépublication de l’article: Complications […]

  Objective assessments to quantify crystalline lens density are becoming indispensable for modern cataract surgeons, in particular when assessing early to moderate-stage cataracts, in which case clinical assessment might be less reliable, as well as when documenting cataract progression. Objective measurements are especially relevant given the recent focus on early lenticular changes, which can be […]

The optical design of multifocal intraocular lenses uses concepts that are sometimes difficult to grasp, especially when it concerns diffractive technology and chromatic aberration control. We published an article (available here) that is based on the optical bench analysis of several models of multifocal diffractive implants to describe their main optical characteristics and report their […]
