Cataracts represent one of the most prevalent age-related eye diseases, significantly impacting vision among older adults worldwide. This condition is characterized by the clouding of the lens within the eye, which leads to a progressive decline in visual acuity. As individuals age, biochemical changes in the lens occur, such as protein aggregation and oxidative stress, contributing to the opacification of the lens (Sharma et al., 2020). The rise in oxidative damage and the accumulation of metabolic waste products exacerbate the clouding, ultimately impairing light transmission to the retina. Several risk factors heighten the susceptibility to cataracts, including prolonged exposure to ultraviolet light, smoking, diabetes mellitus, and genetic predispositions. The aging process itself induces alterations in lens elasticity and transparency, making the elderly more prone to developing cataracts (Li et al., 2021). The disease usually progresses gradually, beginning with minor visual disturbances like glare and blurred vision, which can severely impede daily activities if untreated. Early detection and intervention are crucial in managing cataracts effectively, especially as they age and worsen over time.
The pathophysiology of cataracts involves the disruption of lens fiber cell homeostasis and protein structure. As aging lenses experience oxidative stress, structural proteins such as crystallins denature and aggregate, forming opacities (Chen et al., 2019). This process is exacerbated by environmental factors and systemic health issues, which accelerate lens deterioration. The biomechanical changes also reduce the eye's ability to accommodate, further impairing vision. Treatments for age-related cataracts primarily involve surgical removal of the opacified lens, replaced with an intraocular lens implant (Femtosecond laser cataract surgery), which is highly effective and safe (Kumar et al., 2022). Non-surgical options are limited to visual aids for early or mild cataracts. Surgery's success hinges on early diagnosis before significant visual impairment occurs. Advances in surgical techniques have improved outcomes, reduced recovery times, and minimized complications, making cataract surgery a routine and highly successful procedure for age-related cataracts (Choi et al., 2021). Regular eye examinations are essential for early detection and timely intervention, which can dramatically improve quality of life in aging populations.
