Cataract surgery is a surgical procedure to treat cataract where the change in the lens of the eye cause cloudy and blurry vision. In this condition, the natural lens of the eye has developed an opacification. This opacification is known as a cataract. It affects many people all over India and becomes prominent as we age. Diagnosis of this cataract is done with the help of specialized viewing instruments.
The decision to go ahead with the surgery is taken based on the amount of difficulty that is suffered in performing daily routine activities. There are different varieties of a lens that can restore vision in different ways. The main reason why cataract is preferred by everyone is that it is a safe procedure with minimal complications.
A cataract is an eye disease in which the normally clear lens of the eye becomes opaque which causes a decrease in vision. It is a gradual process but occasionally it can develop very rapidly too. It can affect one or both the eyes. The precise cause of cataract is not known. Some of the factors that are related to this condition are ultraviolet light exposure, diabetes, smoking, steroids etc. It is identified with the help of the following signs –
It is the most common method of cataract surgery which gets over in 30 minutes. Numbing eye drops or an injection around the eye is used and no stitches are required. It is not performed with the help of laser but a femtosecond laser is used immediately prior to the emulsification of the lens.
Extracapsular cataract surgery
It is done for advanced cataract in which lens is too dense to dissolve into fragments or when phacoemulsification is not possible. A large incision is required so that the cataract can be removed in one piece. To close the wound, various sutures are required.
Intracapsular cataract surgery
In this surgery, the surgeon removes the entire lens together with the surrounding capsule and requires an even larger wound than extracapsular surgery. It is rarely used but useful in certain conditions.
