Hi, Chemosis is the non-specific specific conjunctivitis, mostly allergic. it can be seen in dry disease also as the ocular surface is already compromised and prone for inflammation. You can use medicine from your cataract surgery itinerary (if they are not old or expired) for the day. but you are required to consult your ophthalmologist for exact diagnosis and treatment. Continue with Restatsis and Refresh Tear eye drops (dose of refresh tears can be increase if eye irritation persists). You can also take oral anti-histamine tablet (like Cetrizine) if its available with you. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Saurabh Mittal, Ophthalmologist
