What is cataract surgery? Why would you need it?
Cataract surgery is a procedure to remove your eye lens and replace it with an artificial lens to support a clear vision. Every year thousands of cataract surgeries are performed to correct the vision of people with such a vision defect.
People in their old age might start experiencing haziness in their vision, due to the development of a cloudy layer in front of the eye lens, which usually cannot be corrected with eyeglasses, contact lenses, or LASIK surgery procedures.
Facing problems with vision and still delaying appointments might lead to the seriousness of this disease.
People with advanced cataract conditions might experience other problems related to the eye like glare, light sensitivity, dullness of colours, a halo around lights, haziness, and shadow around objects while looking at distant or near objects.
These all might lead to you facing difficulty performing basic tasks like driving at night or working on your laptop & mobile screens.
In such a case going for cataract surgery might be the only safer option.
Cataract surgery: the procedure
Before the surgery :
A week or two before the surgery your cataract eye surgeon might perform a painless ultrasound test to analyze the shape & size of your eye, this process helps determine the right type of lens implant.
You will be provided a choice out of different intraocular lenses (IOL) available, made of plastic, silicon, or acrylic. Choose the comfortable & right fit for your eyes in discussion with your eye surgeon.
During the surgery :
Cataract surgery is usually performed by an eye doctor(ophthalmologist) on an outpatient basis, which means you are not required to stay in the hospital after the surgery.
For a painless experience, your doctor will apply numbing eye drops to your eyes. Once you are ready for the surgery, the cataract surgeon will make a tiny cut on the side of your cornea(the clear outer layer at the front of your eye).
A laser can also be used to perform this step. Then after a small surgical tool is passed through this incision to emulsify the cataract and gently suction it out. The cloudy impaired lens is removed during the procedure and an artificial lens is implanted in its place.
After the surgery :
After the surgery is done successfully your normal vision begins to restore after a period of a few days, as your eye heals and adjusts to the newly fitted lens.
You might also face some discomfort initially with your sight, like an increased intensity of colors, or itching in the eyes. You must refrain from unnecessarily rubbing or pushing your eyes.
The discomfort disappears within a few days. In case of a persistent feeling of uneasiness, days after the surgery is performed, you should immediately contact your doctor.
Overall cataract surgery is an easy procedure that might only foster mild discomfort during the whole process. Most patients who undergo cataract surgery recover really well. About 99 percent of the time, it works.
