Recent epidemiological studies suggested to lower the threshold dose for radiation induced cataract in the eye lens. Therefore, eye lens radiation protection became to play a more important role in personal dosimetry. The main objective of this work is to propose a new methodology for prototyping and benchmarking of an eye lens dosimter based on the equivalent dose to the sensitive part of the eye lens, using CAD Software and Geant4 Monte Carlo simulations with mesh modelling and 3D printing. A 3D printed dosemeter was type tested based on IEC 62387:2012, in terms of energy and angular dependence for the measurements of Hp(3). The results show that the methodology employed is suitable for the development of new eye lens dosemeters.

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.

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.

Purpose: Anterior chamber air injection (ACAI) is a surgical technique used to decrease the occurrence of postoperative intraocular lens (IOL) haptic dislocation following phacovitrectomy with gas/air tamponade. The impact of this technique on IOL stability remains uncertain, prompting the design of this study to investigate further.
Methods: This study included 51 eyes of 51 patients who underwent phacovitrectomy with gas/air tamponade.
