Advair HFA and eye disease

I am 35 yrs. old and have been using inhaled steroids(albuterol,asmacort,vanceril, and Avair) for the past 16 years. I had noticed my eye vision deteriorating over the last 11 years. I was diagnost with and eye disease called kerataconis. i suspect a connection to my asthma medication use. I can only see effectivly with aid of special lense glasses, or hard contacts. I have since ceased use of Advair, and all inhalers , hoping to halt further progression, and the need for corneal trans plants. Too bad for me that Advair and the drug companies didnt fully do a better job warning the public 11 years ago when it could have made a difference.
