Intraocular lens scaffold pupilloplasty: A novel technique for pupilloplasty in phakic eyes

open access: yesIndian Journal of Ophthalmology, 2021
Numerous techniques of pupilloplasty have been described to restore iris anatomy. However limitations arise in phakic eyes due to the propensity for crystalline lens damage.

A Rare Case Report of Unilateral Twin Crystalline Lenses

open access: yesDelhi Journal of Ophthalmology, 2020
We report a rare case of congenital twin crystalline lenses in an eye. The longest visible iris diameter was oblique, drawn from temporal to nasal quadrant making cornea horizontally oval. The crystalline lenses were found to be situated obliquely on the

Effect of Tropicamide on crystalline Lens rise in low-to-moderate myopic eyes

open access: yesBMC Ophthalmology, 2020
Background Cycloplegics have been reported to induce changes in the lens thickness. However, the studies of correlation between cycloplegia and the lens position are limited. This study aims to investigate changes in crystalline lens rise (CLR) and other

Assessment of tilt and decentration of crystalline lens and intraocular lens relative to the corneal topographic axis using anterior segment optical coherence tomography. [PDF]

open access: yesPLoS ONE, 2017
To investigate the tilt and decentration of the crystalline lens and the intraocular lens (IOL) relative to the corneal topographic axis using anterior segment ocular coherence tomography (AS-OCT).A sample set of 100 eyes from 49 subjects (41 eyes with ...

Fabrication and transfer print based integration of free-standing GaN membrane micro-lenses onto semiconductor chips [PDF]

open access: yes, 2022
We demonstrate the back-end integration of broadband, high-NA GaN micro-lenses by micro-assembly onto non-native semiconductor substrates. We developed a highly parallel micro-fabrication process flow to suspend micron scale plano-convex lens platelets from 6" Si growth wafers and show their subsequent transfer-printing integration.
