Presbyopia Correction in Lens Replacement Surgery: A Review

Clinical &Experimental Ophthalmology, Volume 53, Issue 6, Page 668-681, August 2025.
ABSTRACT Presbyopia affects approximately 1.8 billion individuals globally, posing significant challenges as life expectancy and near‐vision demands, particularly with mobile phone use, grow. Addressing presbyopia during lens replacement surgery has become a key focus for cataract surgeons, aiming to reduce dependence on corrective eyewear. This review

The Homburg‐Adelaide toric IOL nomogram: How to predict corneal power vectors from preoperative IOLMaster 700 keratometry and total corneal power in toric IOL implantation

Acta Ophthalmologica, Volume 103, Issue 1, Page e19-e30, February 2025.
Abstract Purpose The purpose of this study is to compare the reconstructed corneal power (RCP) by working backwards from the post‐implantation spectacle refraction and toric intraocular lens power and to develop the models for mapping preoperative keratometry and total corneal power to RCP.

Curved geometric‐phase optical element fabrication using top‐down alignment

Nanophotonics, Volume 14, Issue 4, Page 523-534, February 2025.
Abstract Advanced optical technologies, such as next‐generation displays and holographic systems, demand high efficiency, lightweight designs, compact dimensions, and compatibility with curved and thin substrates. However, current optical devices for virtual and augmented reality displays, such as surface relief and holographic gratings, face ...

Revisiting Trifocal Tensor Estimation Using Lines

, 2014
In this paper, we revisit the problem of estimating the trifocal tensor from image line measurements. With measurements of corresponding lines in three views, a linear method [1] requiring 13 lines was developed to estimate the trifocal tensor from which

Middle‐aged migrants: Expanding an understanding of lifecourses and linked lives

Global Networks, Volume 24, Issue 4, October 2024.
Abstract This paper explores a new perspective on middle‐aged migrant women. Midlife has long been presumed to be the most networked stage of life for sedentary populations, but it has not been examined critically in the context of migration. This is an empty space that warrants research attention, because middle‐aged migrants often have lives that are

The Role of ICT in Maintaining Social Cohesion: Understanding the Potential of Digital Initiatives for Social Networks in Rural Areas☆

Rural Sociology, Volume 89, Issue 3, Page 545-573, September 2024.
Abstract Digital initiatives may have helped to maintain active social networks during restrictive, social distancing measures of the COVID‐19 pandemic. To examine how and under which circumstances digital initiatives can contribute to social cohesion, semistructured interviews with 35 stakeholders of local communities and clubs were conducted.
