Cataract - Causes, Symptoms and Treatments

What is Cataract?
Cataract is clouding of the lens of the eye causing blurred vision. This clouding can be slight to complete opacity causing obstruction in the passage of light leading to decrease in vision. It can affect one or both the eyes. It is commonly related to the ageing process.

What are the symptoms of cataract?
1. Cloudy vision
2. Double vision
3. Blurred vision
4. The need to change glasses frequently

What are the Causes of Cataract?
One of the most important cause of cataract is increasing age.

Few other causes of cataract are:
1. Diabetes
2. Hypertension
3. Ultraviolet rays
4. Injury to eye
5. Previous eye operation
6. Family history of cataract
7. Smoking

Is cataract specific for any age? Can cataract occur at any age?
Though cataract is usually seen in increasing age; it is no longer the case. Cataract can occur at any age including in children (congenital cataract).

How is cataract treated?
An eye operation for cataract is the only way to treat cataract. Cataract eye operation involves removing the cataract or the clouded lens that has becomes non-functional. Cataracts are treated by a surgery called Phacoemulsification. It is the most advanced techniques to remove cataract through a minimum 2 mm incision. After removing the lens, an artificial lens called as an intraocular lens (IOL) is inserted into the eye to correct vision.

Will anaesthesia be used for cataract operation?
Yes. Numbing eye drops would be added to the eye.

How long will the cataract operation last?
It usually lasts anywhere up to 30 minutes.

What are the choices of the lens after cataract operation?
At AEHI, we believe in providing the best care to your eyes. We believe everyone’s eyes are different and hence the cataract treatment is customised. The cataract team shall discuss with you and understand your vision expectations after cataract surgery and accordingly suggest the best cataract treatment. Here are the following options:

1. Mono-focal lenses:
These lenses come in various strengths just like the glass lenses. Depending on individual preference for close vision or distance vision only the lenses of that specific power are used. So, if you choose to have a close vision then the lens power would only be helpful in reading a newspaper or doing detailed work but one would need glasses for distant vision in carrying activities like driving.

2. Multifocal Lens Implantation:
If you want freedom from glasses after cataract eye operation, these are your best bet.

3. Refractive Lens Exchange (RLE):
This is an option for patients who are in middle age and more prone to develop cataract due to increasing age. In this procedure, the patient’s own lens is removed and replaced with a foldable multi focal lens. The advantage of this operation is that the patient does not need cataract surgery in future. This option is better suited for those with farsightedness along with presbyopia or those where early cataract changes have already started.

4. Monovision:
This is a great option for patients who need close and distant vision. In this the dominant eye is corrected for distance and the other eye is adjusted for reading the correction. Before going ahead with the surgery; a trial of contact lenses is done where one eye’s contact lens is adjusted for distance correction and the other eye for reading. If the patient feels comfortable with the vision, then mono-vision surgery is planned.

5. Toric Lens:
Patients who have high astigmatism and will undergo cataract surgery would be best candidates for the toric lens.

How soon can I go home after the cataract operation?
You would be kept for observation for 30 minutes to 1 hour in the hospital after which you can go home. You would be given post-operative instructions and prescription and then would be discharged from the hospital.
