I had an Pterygium removed from my eye around 5 years ago, but it came back within a month. I need advice PL?

I researched the problem I have and it seems to be called "Pteryguim" It's this growth that I had in my eye) It covers one side of the white of the eye. I had it removed. My eye had to go through a lot of healing as it was purple for days because of all the blood circulations post-operation time. After around a month or two the growth comes back in my eye. Started small, and then became one standard size. I've gone to another doctor this time (the best in my city) who said that my operation wasn't done with enough care and that this growth is NOT cancerous and that I could have another operation if I wanted but they can't guarantee it won't re-occur like it did already. I depend on tears drops because that makes the growth go from the colour pinkish/red to a light skin colour and it helps that eye of mine as it is dry. At night it's a must for me to use the drops because my eye gets so dry because of the m that it hurts to open it. I'm a youngster, a pretty one too but the thing is because of this one eye that I am ashamed for people to stare at, I have covered it with a side-fringe and lose so much of my self confidence as I never am able to look someone in the eye. I WANT a successful sugery so I can gain ALL my confidence back :'( Is there any permanent cure for this? I am ready to go all out to get a normal beautiful eye. What about an eye transplant? Someone PLEASE help me. :(
