It is a thick, cloudy area that develops on the lens of your eye. Cataract rises when proteins make a clot in the eye, preventing the lens from transferring a clear picture to the retina. The retina converts light through the retina and converting it into a signal objectively. It sends a sign to the optical nerve and then transmits it to the brain. It grows slowly and ultimately affects your vision.
In the early stages, more powerful illumination and spectacles can help with cataract. You may need to have cataract surgery if your impaired sight gets in the middle of your daily chores. Fortuitously, cataract surgery is usually a safe and effective method.
What are some early signs of cataract?
- Your vision gets dim, blurred or clouded
- You face difficulty with your sight at night
- You develop sensitivity to glare and light
- You see colours as faded
- Seeing halos enveloping lights
- Need to switch to more illuminating light while reading
- Developing double vision in the eye that is affected
- Changing specs or direction for contact lens frequently
What are its causes?
Excessive production of oxidants, that is oxygen particles that undergo biochemical changes due to regular daily life. Smoking, ultraviolet emission, long-term usage of steroids and other drugs, certain medical conditions, such as diabetes and trauma, are the principal causes of cataract.
Most cataracts occur when growing old or trauma alters the lens tissue of the eye. Certain inherited genetic diseases that create other health predicaments develop the risk of the same.
Its different types –
- Nuclear cataract- It is formed in the centre of the lens and causes the core or centre to become yellow or brown.
- Cortical cataract– It is wedge-shaped and grows along the sides of the nucleus.
- Posterior cystic cataract- It forms quicker than the other two kinds of cataracts and affects the rear of the eyepiece.
- Congenital cataract– It occurs at birth or the first year of a child’s life and is less prevalent than growth-related cataract.
Different surgeries for cataract
- Phacoemulsification surgery- It involves the usage of ultrasound to destroy the lens and eliminate debris.
- Extracapsular surgery– It includes excluding the opaque part of the lens by a deep cut in the cornea.
- Intracapsular cataract surgery – In it, the whole lens and the enclosing capsule are removed.
A person with this problem should visit their trusted eye doctors for cataract surgery.
