Eye cataracts are a common defect among many people. This is usually evidenced by the clouding of the lens and thus causing them to get translucent. In as much as many people tend to ignore it, the defect is the most prevalent source of blindness among people who are 40 years old and above. The disorder mostly arises from aging.
Types of Cataracts
It often affects the back-side of the lens. Subcaspular cataracts are most prevalent among people who take substances containing high levels of steroids and also those who are affected by diabetes. The chemical substances in drugs used to treat diabetes and steroids affects the lens, thus making the eyes to have a milky appearance.
This condition forms in the deep-lying and central parts of the lens. It is not caused by chemical agents but rather by the ageing process. This condition causes blindness among many old people.
This type of cataract is often evidenced by cloudy mistiness, which starts forming at the edge of the lens and slowly moves towards the centre. Their movement usually leaves behind a characteristic spoke-like pattern. Corticals rank as the most common type of cataracts.
Signs and Symptoms
This disorder mostly starts on a small scale and gradually develops within the eye. Initially, patients experience marginal hitches in their vision. Most victims attest to the fact that at the beginning, it is akin to looking through a milky piece of glass. It has also been noted that those who are afflicted start getting affected by light of low intensity. Their colour visibility also plummets. In addition, they find it hard to drive at night. It has been discovered that nuclear cataracts may cause a temporal enhancement in the vision of the sufferer. This is however short lived and wanes out after a few days.
The most effective way of keeping the condition at bay is avoiding risk factors, which include continued exposure to intense UVB and smoking. Wearing sunglasses particularly in summer is important because it slows down the development of the disorder. It is also advisable to increase the uptake of antioxidants and foods that contain lutein and zeaxanthuin, which help protect the eyes.
Those who are affected by this disorder need to have a Singapore eye centre contact. Such a specialist is of importance when it comes to offering advice about the most suitable intervention. Nonetheless, surgeries are the most common method used to correct the defect. This is done to remove the cloudy particles, which are the cause of vision impairment. The most common type of surgery conducted is phacoemulsification, which involves the use of ultrasonic energy to clean up the affected lens.
In extreme cases, the entire lens is removed and replaced with a synthetic one. Though expensive, this procedure has a relatively high success rate.
