Cataracts refer to that the crystalline lenses become muddy and are not transparent, which impede the lights from entering the eyes, thus hindering the vision, and sometimes can lead to blindness. It is usually by the means of taking a surgey to help patients with cataracts recover their vision. There used to be a mistake that only when the cataracts become mature is the best tome to take a surgery. This is really wrong. Nowadays, as long as the cataracts have affected your normal life making it hard to see clearly, then a surgery is available. On the other hand, there are still some cases in which the time for a surgery is some kind of limited. For example, if the eyesight is lower than 0.1, and the eyes cannot be seen, then the patient should take a surgery as soon as possible. Secondly, if the patient was born with cataracts with the eyesight lower than 0.3, then the surgery should be done at the age of two to three years old. And if the eyesight is more than 0.3, then the surgery can be put off to four or five years old, but not later than six years old, otherwise it will cause irreversible weak sight. You had better go to the hospital to take overall examination so as to make sure whether it is the best time for you to take a surgery to treat your cataracts.
