Who needs a cataract surgery?
If a person’s everyday activities are affected due to cataract (such as difficulty in seeing or partial blindness while reading or writing), then it is essential to undergo a cataract surgery.
In many cases, the cataract blocks the lens and prevents from diagnosing other the eye ailments. Hence in order to have observational access, deeper into the eye, the doctors will recommend removing the cataract even if the cataract causes only mild symptoms.
- Changes in the retina (the tissue at the back of the eye) seen with older people.
- Diabetic retinopathy - an eye disease that affects diabetics.
How is the procedure carried out?
The patient will be made to undergo various tests on the eye in order to determine the size, shape and contours of the eye a week or two before the treatment. This will help the doctors to choose the ideal artificial lens that will suit the patient’s eye. The patient will be asked to not eat or drink anything 12 hours before the surgery.
The procedure normally takes an hour or less depending on the severity of the cataract formed in the lens. The patient will be usually awake during the procedure but the eye region will be numbed using local anesthesia.
The surgeon will first make a small incision in the front of the affected eye, over the lens, and a laser might be used to assist the procedure. Then, a little instrument will be inserted to remove the cataract by gently breaking it into pieces and sucking the pieces slowly out of the eyes.
Once this is done, the incision will be sewn back and the new lens, replacing the old one, will be fixed in place at the end of the procedure. This lens will be made up of plastic, acrylic or silicone.
If the patient has cataract in both the eyes, they may be asked to appear again, a few weeks later after the first surgery, to get the other eye operated. This is done in order to allow the first eye to heal before operating upon the second one.
What are the possible risks involved in the Cataract surgery?
In most cases, the cataract surgery doesn’t cause any complications, however, some of the possible side effects seen after the surgery in a few cases are as follows:
- Infection in the eyes
- Swelling
- Vision blurring due to remains of cloudy pieces
- Dryness in the eyes
- Allergy due to anesthesia
- Retinal detachment
- Bleeding
What can you expect during the post operative care of cataract surgery?
The patient will normally be asked to leave the hospital on the same day of the surgery, as this procedure is commonly done in an outpatient setup.
The eyes might feel irritated due to surgery or may feel itchy for some days post-surgery. Due to this feel, the eyes may leak/shed tears frequently and this might result in difficulty seeing bright lights.
The patient will be prescribed eye drops in order to stop any infection from developing. In few cases, the doctor might prescribe some antibiotics to avoid fever. The patient will be asked not to strain the eyes and stare for an elongated period into any light emitting object.
The patient will also be advised to avoid reading or writing or possibly avoid any activity that puts pressure on the eyes.
Wearing eye shields during sleep for a week just after the surgery will help to ease off pressure on the eyes, while also protecting the operated region and promote faster healing.
The patient will be back to normal and can continue with the usual activities after 8 weeks of the surgery as the eyes will be completely healed by then. Most patients can see clearly after the cataract surgery and the accuracy rate of the surgery is found to be close to 90%. However, the patients might still be asked to wear glasses or protection gears until 100% of the vision is regained.
