When an individual experiences blurring of the vision, then it is an indication that the patient might require surgery in the near future. The daily activities of the individual might get affected due to impairment of the vision, and that might be the right time to seek medical help. If the patient has a cataract in both eyes, the eye that is having more severity is treated first.
The progression of the cataract depends on the type. A few types of cataract have the tendency to progress rapidly and causes blurring of the vision within a short period of time. Other types of cataracts progress very slowly, and the patient requires treatment only after one or two years.
Cataract surgery is not a painful procedure. The patient will be given anesthesia before the initiation of the surgical procedure. After a few hours, the effect of anesthesia will subside, and the patient will not feel any numbness. The discomfort experienced by the patient will stop after one or two days.
If the cataract develops into a more advanced stage, then the time taken for recovery is also prolonged. So, if the condition is treated early, the complications of visual impairment can be prevented. It is always a better option to treat the condition of cataracts in the initial stages itself.
- After cataract surgery, you are advised not to lift heavy weight. You should also avoid creating pressure on your eyes by watching television and playing video games. Try to avoid sneezing.

Most of the patients require cataract surgery only after the age of 40. The occurrence of cataracts in young patients is very rare.

If younger patients are affected by cataracts, then there are no specific complications for cataract surgery.
The latest treatment for cataracts is intraoperative wavefront aberrometry. After the removal of the cataract, the refractive errors in the eye can be treated in the later stages. The appropriate power of the lens is adjusted so that the individual can correct their vision after the completion of the surgery.
Preventive measures for cataracts are not much difficult to incorporate into a lifestyle.
- Avoid steroid eye drops.
- Live a healthy lifestyle.
- Prolonged exposure to UV light must be avoided.
- Consider cataract surgery.
- Check side effects of the medications provided.
If the cataract is not treated properly, it might result in blindness in some patients. The blurring of the vision will prolong until the patient undergoes proper treatment for it. The pressure in the eyes also keeps increasing. It can also result in infection, bleeding, and inflammation of the eyes.
