Changes in Dimensions and Functions of Crystalline Lens in High Myopia Using CASIA2 Optical Coherence Tomography

Ophthalmic Research, 2022
Introduction: Crystalline lens is the major dioptric component and varies with refractive status. In this study, we aim to evaluate the changes of dimensions and functions of crystalline lens in high myopia (HM) and its correlated variables using CASIA2 ...

Estimation of the full shape of the crystalline lens in-vivo from OCT images using eigenlenses.

Biomedical Optics Express, 2022
Quantifying the full 3-D shape of the human crystalline lens is important for improving intraocular lens power or sizing calculations in treatments of cataract and presbyopia.

Distributions of crystalline lens tilt and decentration and associated factors in age-related cataract

Journal of cataract and refractive surgery, 2021
Approximately 10% of cataract patients have a tilt of 7 degrees or greater and decentration of 0.4 mm or greater. Axial length, front curvature radius, lens thickness, and age correlate with tilt and decentration.

Quantitative analysis of internal components of the human crystalline lens during accommodation in adults

Scientific Reports, 2021
To quantitatively analyze changes in the inner components of the human crystalline lens during accommodation in adults. Eyes of 23 subjects were sequentially examined using CASIA2 Optical Coherence Tomography under 0D, − 3D and − 6D accommodation states.

Multimodal quantitative optical elastography of the crystalline lens with optical coherence elastography and Brillouin microscopy.

Biomedical Optics Express, 2020
Assessing the biomechanical properties of the crystalline lens can provide crucial information for diagnosing disease and guiding precision therapeutic interventions. Existing noninvasive methods have been limited to global measurements.

Stiffness gradient in the crystalline lens [PDF]

Graefe's Archive for Clinical and Experimental Ophthalmology, 2007
While the overall stiffness of the lens has been measured in a number of studies, the knowledge about the stiffness distribution within the lens is still limited. The purpose of this study was to determine the stiffness gradient in the human crystalline lens.
