Both of those contact lenses are good brands, although I personally am not too fond of gas permeable lenses. There are soft multifocal and bifocal contact lenses available now. I find that patients tolerate soft contact lenses better than gas permeable ones (just my opinion).
Also, there may be a change in your eyes that is precipitating protein deposits (conditions such as meibomitis or giant papillary conjunctivitis or dry eyes). These may all be treatable. Perhaps a change in cleaning solutions (sometimes, companies change the preservatives in their solutions without telling anyone and this can lead to increased irritation in some people).
These are all questions to take back to your physician. Give him/her a chance to work with you to improve the situation before you fire him/her.
Hope this helps.
