The natural lens of the eye is transparent. When a cataract clouds the lens of the eye, it leads to vision loss. This cloudiness prevents light from passing through the eye and due to this the vision of the person turns blurry. It can affect a single eye at a time or even both the eyes. This condition is especially common amongst people over the age of 55.
It is done under anaesthesia, where the patient will feel no pain. Anaesthesia can be in the form of a local injection or could just be performed by instilling anaesthetic eye drops (topical anaesthesia). Patients will be aware of a bright light during the surgery but will not experience pain. Patients return home on the same day, infact within 20-30 minutes post-surgery.
The surgery process involves removing the old cloudy lens with ultrasound energy/Laser and replacing it with an artificial lens. The different types of lens that can be used are:
In most cases, the patient experiences an improvement in vision almost immediately. The cut in the eye heals by itself though it might take a few weeks to heal completely. Patients can follow their daily routine but vigorous activities should be avoided for a while. A new pair of eyeglasses will be needed and the eye test can be done after a few weeks post-surgery. If both the eyes need surgery, the surgeries can be done a week apart.
