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

Crystalline lens imaging with a slit-scanning system [PDF]

open access: yes, 2011
[Introduction] The human crystalline lens plays a fundamental role on the retinal image quality. The ability of the lens to change its shape and, consequently, the total refractive power of the eye, during accommodation, enables one to focus objects at a
