Cataract is a medical condition marked by the formation of a cloudy layer on the surface of the eye. It is one of the most common eye problems that usually affects middle-aged or elderly people. The problem proceeds very slowly and ultimately leads to complete loss of vision. Cataract can be easily removed with the help of surgery. The treatment for cataract is available at all the leading eye hospitals. In the earlier stages, the symptoms are not easily visible but gradually as the patient's I side becomes weaker it becomes not evident that he or she is suffering from cataract. Cataract can severely affect your quality of life and make you dependent upon others. Earlier the treatment for cataract was available only at a few hospitals in India but now you can easily avail for the services at all the leading eye hospitals.
Cataract can be of three different types i.e subcapsular cataract, nuclear cataract and cortical cataract. Crotcal cataract as the name suggests originates in the cortex of the lens i.e the part surrounding the central nucleus. It is marked by the formation of white, wedge-shaped structures or opacities that originate in the periphery of the lens and spread towards the centre in a spoke-like manner. Cortical cataract leads to local disruption of the structure of mature fibre cells and triggers the loss of essential metabolites from these. As a result of this daily chronic protein oxidation as well as precipitation. Cortical cataract does not show any symmetry and is mostly bilateral. The pace at which the problem proceed varies greatly. In some cases, the opacities remain unchanged for a very long period of time whereas in some other cases they progress at a very fast pace.

During the initial stages, there is a formation of vacuoles and water clefts in the anterior and posterior cortex. The opacities originate from the peripheral part of the lens with the ends pointed towards the centre. Owing to their shape, these are also known as cortical spokes or cuneiform opacities. These gradually spread towards the centre and when they cover the entire cortex, the cataract is said to be mature and is marked by the whitening of the cortex. When the opacities become mature, the lens absorbs water and swells leading to intumescent cortical cataract.

In some cases, a mature cataract can degenerate and the water may leak leaving behind wrinkled and shrunken capsule. The symptoms of cortical cataract are somewhat different from the other two types of cataracts. It often leads to swelling and disruption of the lens fibres. The patient may find it very difficult to drive in dim light and especially during the night. The patient may experience blurred vision accompanied by the formation of blurry lines. There is a gradual loss of vision over time and sometimes it only affects one eye whereas the other remains intact. The patient finds it difficult to stay in bright light and go out in direct sunlight. It is not necessary that one experiences all of the symptoms. Even if you experience any one of these symptoms it is better to consult a doctor and get your eyes checked. The doctors may conduct several tests and examine your eyes to determine the root cause of the problem and offer the best possible treatment. In some cases, prescription glasses and bifocals can help to solve the problem to some extent by correcting the patient's vision. Sometimes the lenses prescribed are of greater power so as to help you to see clearly. Although these treatment options can help to correct your vision, this is only temporary as the eyesight of the patient keeps on deteriorating with time.

One of the best methods to treat cortical eye cataract is with the help of cataract removal surgery. Cataract surgery has helped a lot of patients to get rid of the problem and has given a new ray of hope to many more. If you are planning to undergo the surgery can easily find some of the best doctors in India. Also, make sure that you follow all the guidelines prescribed by your doctor before as well as after the surgery to avoid any complications.
