The ORAMED (Optimization of RAdiation protection for MEDical staff) project is funded by EU-EURATOM within the 7° Framework Programme. Task 2 of the project is devoted to study the dose to the eye lens. The study was subdivided into various topics, starting from a critical revision of the operational quantity H(p)(3), with the corresponding proposal of a cylindrical phantom simulating as best as possible the head in which the eyes are located, the production of a complete set of air kerma to dose equivalent conversion coefficients for photons from 10 keV to 10 MeV, and finally, the optimisation of the design of a personal dosemeter well suited to respond in terms of H(p)(3). The paper presents some preliminary results.

Purpose: To evaluate the clinical outcomes of a new FDA approved toric aspheric hydrophobic acrylic intraocular lens.
Patients And Methods: This is a single surgeon, single-arm, on-label, non-randomized, prospective observational study. Thirty patients underwent bilateral cataract surgery (60 eyes) with placement of a Clareon™ Toric IOL in each eye.

Metal-organic frameworks (MOFs) combined with polymers as hybrid materials offer numerous advantages such as enhanced performances through synergistic effects at their interface. The primary challenge in developing polymer/MOF hybrid matrix films is ensuring optimal dispersion and strong adhesion of crystalline MOFs to the polymer without aggregation, weak interaction, or phase separation. In this study, hierarchically porous UiO-66_NH/chitosan (ZrCSx-) films were designed by crystallizing UiO-66_NH within a chitosan (CS) skeleton.

In laser safety eyewear, due to the lack of complete blocking of ultraviolet and infrared rays, we proposed a structure based on one-dimensional multilayer composed of several layers of silicon dioxide and zirconium dioxide materials alternately behind polycarbonate lens. It is find out that the acceptance angle range to the photonic crystal is 0 to 39°. This incident angle range corresponds to the band gap of the photonic crystal.

We compared the visual performance and subjective outcomes of mini-monovision, crossed mini-monovision, and bilateral emmetropia using enhanced monofocal intraocular lenses (IOLs). This retrospective study involved 200 eyes of 100 patients who underwent surgery for bilateral age-related cataract using an enhanced monofocal IOL (TECNIS Eyhance). The dominant eye was identified before surgery.

Keratoconus is a multifaceted corneal ectatic disorder characterized by a range of genetic and environmental risk factors. While genetic predisposition significantly influences global disease prevalence rates as well as severity and progression rates, emerging evidence highlights the critical interplay between environmental factors and genetic susceptibility. This article provides a comprehensive overview of environmental risk factors implicated in the onset and progression of keratoconus.
