<s>[INST] Hello doctor, I had a consultation with a local doctor, and she told me that I have corneal dystrophy. It is genetic here as my mother also have that. I can see bubbles moving around when I concentrate at any point, it is like tiny white color dots on cornea. I am using spectacles since last few years (cylindrical power, -2(L), -1.5(R)). This dystrophy is not a big problem for now, but it creates a problem when I study or read something. It creates a headache, which distracts me while studying. Can you please suggest me a treatment either prevention through surgery or medication (any eye drop)? Please let me know if you need further details. Thank you. [/INST] Hello. Dystrophies of the cornea are divided based on the layer of cornea involved. If the dystrophy is the cause of your headache, then your dystrophy must involve the outer layers of cornea. More than frank pain, these conditions cause irritation which increases on blinking, more during early morning hours. If this is the case, then the best over-the-counter medication is Lacrigel (2% Hydroxypropyl methylcellulose acetate). This medication is essentially a gel formulation of the drops your doctor has recommended and just like the drops, it will cause no side effects except for mild blurring soon after installation. The exact diagnosis of such dystrophies can be done by a cornea specialist. In case you need any further information, please send a very clear and magnified photo of your cornea. I will do my best to help you. </s>
