How to cure yeast infection in men naturally ? Please reply me?

hi friends, I am 25 years old MALE from Hyderabad, India.

Please tell me something about yeast infection and candida. It will be very much helpful to me.

Whether we can cure the yeast infection permanantly ?

I used heavy dose of antibiotics in feb 2009 as my doctor misdiagnosied my normal fever as malaria and treated me with powerful antibiotics.

From the second day, i had bulged tongue with huge white coating , severe eye problems, breathing problems, severe body pains, joint pains, etc..

I faced all those problems for almost 3 months.

But now the only thing that depresses me is about eyes. Till today i think mine are Eye floaters but today accidentally i read about yeast in eyes. Please see the following image. My vision is almost like this.

I have tons of spots, chains like structures, white and gray dots in my eyes and i cant able to concentrate on anything. If mine is yeast, is it possible to cure it permanently and make my eyes clear ??

And please tell me what is yeast and what is candida infection ?

THOUSANDS OF THANKS FOR YOU ALL IN ADVANCE.
PLEASE REPLY ME AND MAKE ME FREE OUT OF MENTAL TENSIONS. I WILL PRAY FOR YOU.
THANK YOU.
