First read this article about cataract surgery and high myopia:

Then read this article about what you should know before surgery:

Your surgeon's plan to leave you about -2.00 is the solution that works best for most people. I can't imagine that any surgeon would ever leave a person needing glasses as strong as you are use to wearing. After the first operation you can decide what you would like on the second eye. If you want better distance vision you could go with a smaller number like -1.00 or if you wanted more reading power on the second eye you could go for -3.00. You would stand a very good chance of adjusting to multifocal glasses either progressive, bifocal or trifocal or single vision for distance, intermediate or near.
To summarize no surgeon likes to ever leave an eye with a post op refraction stronger than about -3.00 and certainly nothing like you're use to wearing.
re: "to being farsighted"
I'll add the minor correction that the doctor won't be leaving you farsighted, merely just slightly myopic rather than very myopic. Since you will still need to use glasses for distance, it shouldn't be a major change other than letting you do some tasks without glasses.
If you merely like wearing glasses all the time, you can always get non-prescription glasses off the shelf to wear when you aren't wearing distance glasses. e.g. there are off the shelf non-prescription computer glasses with 0 power, or use frames you like and have a non-prescription 0D lens put in.
It isn't clear from your post, would you really prefer to be as myopic as you are now for some reason, is there some task you do very near that you don't wear glasses for? Although as the doctor noted, its unlikely they'd wish to leave you as nearsighted as you are now, perhaps they might go a bit more myopic than -2D, e.g. perhaps -3D, if really close vision is important to you.
