A cataract is an eye condition where the lens becomes cloudy, leading to blurred or impaired vision. While most cataracts are age-related, they can also be present from birth (congenital).
The lens is a clear, flexible structure in the eye that helps focus light onto the retina. Its natural elasticity allows us to see objects clearly at both near and far distances—a process known as accommodation.
When a cataract develops, the lens loses its clarity, making images appear foggy or distorted.
Treatment options for cataracts depend on how advanced the condition is. In early stages, medical treatment is often used, and in many parts of the world, stem cell therapy is now being integrated alongside traditional methods.
What are the benefits of stem cell therapy for cataracts?
The lens is primarily made of a protein called crystallin. Stem cells can improve the metabolism of this protein, helping to slow its breakdown (denaturation) and delay the clouding of the lens. They also enhance collagen metabolism, which boosts the elasticity of the lens capsule—improving both accommodation and overall visual quality.
Noticeable results from stem cell therapy usually appear within 2.5 to 3 months, with effects lasting up to one year.
