Optical and visual quality of real IOLs physically projected on the patient’s eye, published in Biomedical Optics Express

Visual simulators aim at evaluating vision with ophthalmic corrections prior to prescription or implantation of intraocular lenses (IOLs) in the patient’s eye. In a new published study, we present the design, implementation, and validation of a new IOL-in-cuvette channel in an Adaptive Optics visual simulator, which provides an alternative channel for pre-operative simulation of vision with IOLs. IOL-in-cuvette is projected to the pupil’s plane of the subject by using a Rassow system. A second lens, the Rassow lens, compensates for an IOL of 20 D while other powers can be corrected with a Badal system in a 5 D range. The new channel was evaluated by through-focus (TF) optical quality on an artificial eye on bench, and by TF visual acuity in patients, with various IOL designs (monofocal, diffractive trifocal, and refractive extended depth of focus).

Guest editorial to celebrate Journal of Cataract and Refractive Surgery 25th Anniversary

Looking back at landmark articles published in the JCRS (Mester et al. 2003) where visual outcomes with the first aspheric IOLs were presented, the author (Susana Marcos) discusses how increased knowledge of the eye’s optics, aberrometry and new imaging technologies are shaping the present and future of IOL designs and cataract and presbyopic surgery.

Review article on Mechanisms and pathways on myopia development, published in Experimental Eye Research

Myopia affects more than 30% of the population in western countries and more than 90% in some Asian populations. Although it is well established that refractive eye development is a tightly coordinated developmental process, we are still unveiling why and how mypia develop. In a review article we present state-of-the art knowledge of the complex cross-tissue signaling in the disruption of emmetropization, the interaction of the crystalline lens with other ocular tissues during eye growth, the role of accommodation, contrast, monochromatic and chromatic aberrations in eye emmetropization. This review article is collaborative work between authors of University of Oklahoma, University of Tuebingen, Institute of Molecular and Clinical Ophthalmology Basel (IOB), Columbia University, and Instituto de Óptica CSIC.
