What is Cataract?
A cataract is caused when the natural lens of the eye gets clouded. The lens scatters the light as it is clouded, which leads to a blurred vision. It usually develops due to old age, but the condition occurs in infants and young children as well. The symptoms are blurred vision and sensitivity to bright lights. If the disease is not treated on time, it leads to a decrease in vision interfering with day-to-day activities. It may also lead to the inability to drive and read. A healthy lifestyle will help in preventing cataracts, but if it happens, it should be managed by wearing spectacles.
However, as the cataract progresses, it results in deterioration of central vision, which can only be managed by surgery. Cataract Surgery in Ludhiana can be carried out if you are based here. Cataract Surgery involves the emulsification of the natural lens through a process known as phacoemulsification. The lens is sucked out after that. It is followed by the placement of an artificial intraocular lens (called IOL) in the same position by the eye doctor. The new lens is customized according to the patient’s requirements. The new lens helps restore the normal vision. You may opt for Cataract Surgery Punjab if you are suffering from this problem.

What to expect from your cataract surgery
Before Your Surgery
The required strength and type of IOL will be determined by measuring your eyes. Usually, an optical bio meter is used for this purpose. The IOL will be made as per your vision needs.
The Day of Your Surgery
Cataract surgery is usually carried out as an outpatient procedure. You will be fully conscious and there will be minimal discomfort. A local anesthetic will be used before removing the cataract with an ultrasonic probe. The probe breaks up and removes the cloudy lens. It is followed by the implantation of a new IOL.
After Your Surgery
You will be provided with temporary protective glass to cover your eyes. You will have to wear them for some days. The doctor will tell you to use drops to prevent infection and ensure proper healing.
