The LOCS III is an improved LOCS system for grading slit-lamp and retroillumination images of age-related cataract.

—To develop the Lens Opacities Classification System III (LOCS III) to overcome the limitations inherent in lens classification using LOCS II. These limitations include unequal intervals between standards, only one standard for color grading, use of …

Developed by the Epidemiologic Study of Cataract Study Group, LOCS III provides standardized photographic standards to systematically evaluate four distinct types of lens opacities: Nuclear color (NC) – Grades the color or brunescence of the nucleus from 1 (normal) to 6 (brunescent).

Nov 3, 2024 · The LOCs III cataract grading scale consists of five grades: 1) No cataract, 2) Incipient cataract, 3) Cortical cataract, 4) Nuclear cataract, and 5) Posterior subcapsular cataract. Why is the LOCs III cataract grading scale important?

Many types of grading systems have been used to describe cataract severity. Commonly used systems in epidemiological studies include the Lens Opacity Classification System (LOCS, LOCS II, and LOCS III), the Oxford Clinical Cataract Classification and Grading System, and the Johns Hopkins system.

The LOCS III system [23] uses six slit-lamp images for grading nuclear colour and nuclear opalescence and five retro illumination images for evaluating cortical cataract and posterior...

Oct 4, 2024 · One key difference between the LOCs and LOCS III systems is their grading scales for nuclear opalescence, cortical cataract, and posterior subcapsular cataract. The scales used by each system may differ in their range and criteria for grading, which can impact the assessment of cataract severity.

The document describes the development of the Lens Opacities Classification System III (LOCS III), which aims to overcome limitations of the previous LOCS II system.

Nov 1, 2008 · For the LOCS III to be beneficial, physicians of all levels of experience should be able to use the system with low inter-observer variability. The LOCS III comes with detailed instructions about its correct use, what photographic artifacts to …

To determine the diagnostic accuracy of Pentacam Cataract Grading Scale (PCGS) versus the Lens Opacities Classification System (LOCS III) in scaling pure age-related cataract. Between April 2016 and May 2017, eyes of 281 patients were evaluated for grading of lens opacity. We used LOCS III and PCGS.
