Detailed Answer:
Hello
Welcome to Health care magic

I am Dr. DADAPEER K, an Ophthalmologist and I will be answering your question.

I reviewed your history.

The redness and discomfort in the eye following cataract surgery can be because of subconjunctival hemorrhage. This will resolve over time slowly and no need to be worried about this as told by your doctor. No treatment other than routine eye drops is required.

If you are having redness, discomfort and blurred vision then it indicates inflammation of the eye and requires treatment by the use of steroid drugs.
Hence provide me more details like
Whether you have pain, blurred vision?
If possible send a photo of the affected eye so that I can confirm the diagnosis and advice you accordingly.

Hope I have answered your question and the information is helpful to you.
Do write back to me for further questions.

Thank you
