Cataract




What is cataract surgery?


Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision. Cataract surgery, usually an outpatient procedure, takes an hour or less to perform.



Cataract Surgery: Lens Extraction and Prosthetic Lens Insertion

The cataract surgery depicted shows the removal of a cloudy lens via phacoemulsification, and the placement of an artificial lens in the eye. The basic anatomy of the eye and its ability to receive light is contrasted with the negative effects of a cataract lens.



There are different techniques for cataract surgery


1. Phacoemulsification:

In this technique, a micro-incesion (around 3 millimeters wide) is made at the edge of the cornea. With an ultrasound-based technique called phacoemulsification, the cloudy lens is then extracted through the incision.

2. Extracapsular surgery:

This technique involves a larger incision (typically 10–12 mm) on the side of the cornea. The cloudy core of the lens is first removed through the opening and the remaining part of the lens is suctioned out. This technique is best for patients who have very hard cataracts or for those unsuited for phacoemulsification option.

3. FemtoPhaco:

Also referred to as ‘laser cataract surgery’, or ‘laser-assisted cataract surgery’, FemtoPhaco involves a combination of Femto laser treatment and phacoemulsification.



Who is a good candidate for Cataract surgery?


Cataract surgery is performed to treat cataracts cause blurry vision and increase the glare from lights makes it difficult for patients to carry out their normal activities.
When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. Otherwise, you can wait for the cataract to be damages completely without making any problem for other organs.


To prepare before cataract surgery


A week or so before your surgery, your doctor performs a painless ultrasound test to measure the size and shape of your eye and determine the right type of lens implant for you.
You may advise to stop taking certain medications.
Your doctor may advise you to use eye drops to reduce infection risk. Antibiotic eyedrops may be prescribed for use one or two days before the surgery.
You may be instructed not to eat or drink anything 12 hours before the procedure.
Before surgery, you and your eye doctor will discuss which type of intraocular lens (IOL) might work best for you and your lifestyle. Some of the types of lenses available include:
• Fixed-focus monofocal.
• Accommodating-focus monofocal.
• Multifocal.
• Astigmatism correction (toric).



Recovery time of cataract surgery


Cataract surgery is very common and is generally a safe procedure, so there is no need to be hospitalized. Normally you can go home on the same day as your surgery, but you are not allowed to do some activities such as driving, bending and lifting, for about a week after your surgery.
• Colours may seem brighter after your surgery because you are looking through a new, clear lens.
• You’ll usually see your eye doctor a day or two after your surgery, the following week, and then again after about a month to monitor healing.
• Your doctor may ask you to wear an eye patch or protective shield the day of surgery or a few days after your surgery during the recovery period.
• Your doctor may prescribe eye drops or other medication to prevent infection.
