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 […]

 This paper (download: No rub No cone )aims to provide a comprehensive explanation for the physio pathogenesis of keratoconus and demonstrate why it is not corneal dystrophy of genetic origin, but primarily a warpage of the corneal dome of mechanical origin. Keratoconus is not a true ectasia. Rather, it results from the permanent corneal deformation […]

  Can purely axial metrics such as PTA (Percentage of Tissue Altered) predict with reasonable accuracy the ratios of tissue volumes implied in LASIK surgery? To our knowledge, the ratios between the volume of the cornea and that of the tissues involved in LASIK surgery have never been computed. This might allow clinicians to better […]

J’ai l’honneur et le plaisir d’être considéré comme parmi les esprits créatifs (creative minds) du monde de l’ophtalmologie par le mensuel professionel Cataract and Refractive Surgery Today (CRST), esprits auquel un numéro spécial est consacré (Avril 2018). L’interview porte sur des sujets divers comme le métier de chirurgien réfractif, la recherche, les voyages et… la […]

Cet article contient les arguements développés lors d’une communication délivrée au congrès des JIFRO (Journées Interactives de Formation en Ophthalmologie) à Versailles, le jeudi 25 janvier 2018. Un point de controverse, SMILE ou LASIK pour la correction de la myopie, était débattu. Les arguments développés dans cette communication permettent d’étayer la supériorité du LASIK sur […]

The objective diagnosis of cataract is a major public health issue. Early cataract can be ambiguous on a slit lamp. With the Objective Scatter Index (OSI), the HD Analyzer provides an objective measurement of the crystalline lens opacity level by measuring ocular light scattering. However, in some instances, the light scatter can arise from other […]

I have just published a paper about in vivo corneal collagen cross-linking (CXL)  (pdf download :Reevaluating the Effectiveness of Corneal Collagen Crosslinking and Its True Biomechanical Effect in Human Eyes D Gatinel ) and I believe it is certain to trigger some controversy.  It is not my intention to be a heretic, but I truly […]
