Cataract services
Cataract is caused by the degeneration and opacification of the lens fibers already formed, the formation of aberrant lens fibers or deposition of other material in their place. The loss of transparency occurs because of abnormalities of the lens proteins and consequent disorganization of the lens fibers. The reasons for the degeneration of the lens fibers and consequent loss of transparency are not yet clear and probably vary in different cases. Any factor, physical or chemical, which disturbs the critical intra-and extracellular equilibrium of water and electrolytes or deranges the colloid system within the fibers tends to bring about opacification. Epithelial cell necrosis leads to focal opacification of the lens epithelium as ‘glaucomaflecken’ in acute angle closure glaucoma. Abnormal products of metabolism , drugs or metals can be deposited in storage diseases (Fabry), metabolic diseases (Wilsons) and toxic reactions (siderosis).
Risk factors for cataract:
- Increasing age
- Sunlight (especially the UV-A, UV-B components)
- Severe diarrhoeal dehydration
- Vitamins A, C, E deficiency
- Diabetes
- Smoking
- Corticosteroids
- Genetic
Doctors at Supriya Eye Hospital will identify the type of cataract, grade of cataract and perform all types of cataract surgeries including Phacoemulsification and implants all types of IOLs including Multifocal and Toric IOLs too.
