Changes in forward light scatter parameters as a function of refractive error in young adults [PDF]

open access: yes, 2020
Background/aims Some aspects of visual performance worsen with increasing myopia. Whilst the underlying causes are not always clear, reduction in retinal image quality is often attributed to structural changes in the posterior myopic eye.

Air bubble-induced intraocular lens opacification in hydrophobic intraocular lens following posttraumatic cataract surgery: A first-ever case report

open access: yesTNOA Journal of Ophthalmic Science and Research, 2017
A 19 year old male presented with complaints of diminution of vision in right eye. He had undergone cataract surgery in right eye elsewhere 6 years ago for firecracker injury. On examination, eccentric pupil is noticed with intraocular lens (IOL) opacity.

Multifocal versus monofocal intraocular lenses after cataract extraction. [PDF]

open access: yes, 2012
BACKGROUND: Good unaided distance visual acuity is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision, however, still requires additional refractive power, usually in the form of reading glasses ...

Phakic Pattern Pseudoexfoliation Material Accumulation on Intraocular Lens Surface

open access: yesTürk Oftalmoloji Dergisi, 2014
Pseudophakic pseudoexfoliation is the accumulation of pseudoexfoliation material on the intraocular lens. Most of the cases have showed scattered flecks of pseudoexfoliation material on the surface of the intraocular lens.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research

open access: yesAdvanced Healthcare Materials, EarlyView.
Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,
