SETTINGS AND DESIGN: This was a prospective observational study carried out in a hospital attached to medical college. WebCataracts types are defined by where the opacities exist within the lens and graded by how severe the opacities are at that location.

WebMar 2, 2024 · The LOCS is the most commonly used system in the clinics. It allows a qualitative staging of cataracts based on a series of images for grading nuclear color (NC), nuclear opalescence (NO), cortical cataract (C), and posterior subcapsular cataract (P). Three versions have been developed (LOCS I, II, III). WebPurpose: To evaluate objectively intraocular scattering in eyes with nuclear, cortical and posterior subcapsular cataracts by means of an objective scatter index (OSI) obtained from double-pass images. To compare the results with those obtained using clinical conventional procedures. Methods: In this prospective, observational, cross-sectional, non …
WebAug 18, 2024 · Nuclear sclerosis is a normal aging process of the lens. The lens is made of transparent proteins called “crystallins.”. These proteins are arranged in layers and allow light to pass through. With age and exposure to UV light, the proteins in the lens begin to clump together. This causes the hardening and yellowing of the lens nucleus.
