In my opinion it is better to think the other way round, that is how to make the best use of your possibilities.
There is a very successful Russian psychologist who claims that you can achieve and obtain everything you want, if you believe in your inner values and capacities and use them.
In his seminars he seems to reach a rate of nearly 100% in healing all kinds of vision defects within 40 days + between 2 and 6 days per diopter of short- or farsightedness.
His book is not as efficient (maybe because you can't profit as much of his charismatic presentation), but really a pleasure to read and a good course in self-awareness and self-reflection, and may give you some new ideas and impulses for your practice:http://www.norbekov-europe.com/index.php?lang=en
So, if you think, you should first be completely cured before you can continue your 'normal' life plan, maybe it would be worth investing 2 months and try Norbekovs approach and than you can do whatever you like without any obstacle.
