Is Cataract Surgery Safe? What Are The Complications?

Cataract surgery is generally considered a safe and effective procedure and the likelihood of complications is low. However, since it is an invasive surgery, it carries the risk of partial to total vision loss if it is not successful or if complications arise. Some complications can be treated effectively, leading to a reversal of vision loss, while others may not be reversible. Potential complications associated with cataract surgery include:

 

1. Torn lens covering (posterior capsule rupture).

2. Eye infection (endophthalmitis).

3. Swelling and fluid accumulation in the central nerve layer (cystoid macular edema).

4. Swelling of the transparent eye covering (corneal edema).

5. Bleeding in the front of the eye (hyphema).

6. Detachment of the nerve layer at the back of the eye (retinal detachment).

 

Additionally, complications that might occur after some time following surgery include:

 

1. Glare-related issues.

2. Clouding of the back portion of the lens covering (capsule) that remains after surgery. (This can be easily treated using a laser by your doctor).

3. Glaucoma.

4. Retinal detachment.

5. Astigmatism or strabismus.

6. Sagging of the upper eyelid (ptosis).
