Understanding the structure and function of the human lens is crucial in deciphering the origins and progression of cataracts. This book explores the anatomy, physiology, and transparency maintenance mechanisms of the crystalline lens, particularly in relation to cataract development. It details the biochemical composition, protein interactions, and age-related changes that affect lens clarity. Emphasis is placed on the impact of hydration, ion transport, and enzymatic activity on lens function. The text also reviews surgical considerations and innovations in cataract management. It provides a valuable foundation for eye care professionals seeking to connect basic lens biology with clinical practice.
Thulani Ncube is a clinical anatomist and vision science lecturer specializing in the structure and function of the human lens. He has conducted comparative studies on lens aging, refractive changes, and cataract morphology across populations. Thulani is known for integrating microscopic anatomy with physiological optics to explain changes in lens transparency and elasticity. He contributes to both classroom teaching and continuing education for eye care professionals. His academic contributions highlight the role of the lens in maintaining clear, functional vision throughout life.
