Causes of flickering after cataract surgery?

After cataract surgery most patients experience one form or another of light flickering. This is normal and is part of the healing process while the capsule contracts around the new intraocular lens.
After several weeks of adaptation this flickering should stop and go away.

If you are experiencing continuous flickering after cataract surgery it may be caused by one of the following
1. increased light sensitivity due to the newly implanted intraocular lens
2. Increased light sensitivity due to corneal oedema
3. Increased light sensitivity due to raised intraocular pressure
4. A tear or hole in the retina ( retinal detachment or retinal tear)
5. Anterior uveitis due to surgical trauma
6. Shaking of the intra-ocular lens because of instability of the lens
7. Vitritis ( inflammation or infection in the vitreous jelly of the eye)

Proper evaluation of the cause of the flickering should be done and treated accordingly.
In case of a retinal detachment or retinal tear you need emergency treatment.
In case of corneal oedema drops can help get rid of the flickering,
In case of a malpositioned or subluxated lens surgery may be required to fix this issue.

Absolutely love how understanding Dr. Kumud Raut is. The only place where I have not been told about only the process of getting a surgery, but rather they insist on educating about how the eye functions and the importance of having a healthy eye before any surgery.
