Considerations of a thick lens formula for intraocular lens power calculation
Zeitschrift für Medizinische PhysikBackground: In recent years, some lens manufacturers have committed to providing lens shape data for some of their lens models. The purpose of this study is to present a strategy for prediction of intraocular lens power and residual refraction based on a

Lens regeneration in situ using hESCs-derived cells —similar to natural lens
iScience, 2023 Summary: Lens itself has limited regeneration functionality, thus we aimed to create regenerated lens with biological function to treat cataracts rather than the intraocular lens used in cataract surgery.

Scleral contact lens thickness profiles: The relationship between average and centre lens thickness [PDF]
Contact Lens and Anterior Eye, 2019 To develop a methodology to reliably determine the thickness profile of scleral contact lenses and examine the relationship between the centre and average lens thickness for a range of lens designs and back vertex powers.High-resolution images of 37 scleral trial lenses (Epicon LC, Rose K2 XL and ICD 16.5) were captured using an optical coherence ...

Optical Design of a Miniaturized 10× Periscope Zoom Lens for Smartphones
Micromachines, 2023 The size of the optical zoom system is important in smartphone camera design, especially as it governs the thickness of the smartphone. We present the optical design of a miniaturized 10× periscope zoom lens for smartphones.

Optimization of Zoom Lens with Discrete State of Liquid Lens Elements by Using Genetic Algorithm
Advances in Materials Science and Engineering, 2015 This paper is to employ liquid lens elements to design a lens with zoom function by using the genetic algorithm (GA) optimization. The liquid lens elements used in the proposal can apply voltage adjustment to generate the electrical field that induces ...
