Hi MYETH , I am Dr Bilal and I am an Ophthalmologist
Welcome to Health Care Magic
I would like to answer your question and your satisfaction is my goal .
usually doesn't require treatment if symptoms are mild , but as u are giving history of pain and irritation in eyes on exposure to sun light and you are working in a dusty place , I would suggest you to use the following medications . Use these for 02 weeks .
1. Lubricating eye drops or ointments
, such as Blink or Refresh drops ( Put 1 or 2 drops in eye(s) 06 Hourly )
2. Occasional use of vasoconstrictor eyedrops, such as Naphcon
A ( Put 1 or 2 drops in eye(s) 08 hourly )
3. Short course of steroid
eyedrops, such as FML or Lotemax
The definitive treatment in your case is surgery, as the reddish membrane has grown very close to the cornea and in later stages it may interfere with vision .
If you have any other questions , i am here to answer you .
Best regards .
