Detailed Answer:
Hello
Welcome to Health care magic.

I am Dr. Dadapeer K, an ophthalmologist and I answer health problems related to eye.

It seems from the history that you had a eye infection, with involvement of cornea in the form of keratoconjunctivitis.
This had resulted in filaments in one eye and corneal erosions in another eye. These have healed resulting in development of corneal scars.
Corneal scars involving the superficial layers of cornea will be replaced by clear corneal epithelium in 1-3 months, depending on the number and density of opacity.
The corneal scars involving deeper layers of corneal epithelium may take 3-6 months for complete healing.
The treatment is by use of artificial tears and you can continue them.

Hope I have answered your question and the information is helpful to you.

Thank you
With regards
