Cataract surgery cost is influenced by various factors, including the development of cataracts in one or both eyes due to the natural aging process. This clouding occurs in the natural lens of the eye. Apart from age, other factors contributing to this condition are genetic disorders, past eye surgery, diabetes, uveitis, eye trauma, etc. Basically, cataract occurs due to protein denaturation which prevents light from passing through the natural lens of the eye and thereby causing hazy vision.
