1. Get a good lamp with a bright light that sits near a comfortable chair so you can see as well as possible.
2. Be patient with yourself. Make a few small items, potholders, table runners, etc. and use them for practice.
3. I do better without any hoop. I pin, baste, or glue the project so it will not slip and just quilt in my lap, this makes it easier to get up closer to my face or nearer to the light if necessary.
4. Practice, practice. Remember it isn't necessarily the size of the stitch but how even it is that is important. That comes with practice.
5. Post what you make for us and tell us what problems you are having. Perhaps we can be of more help.
6. You can use contrasting thread if that helps you to see your work better.
I just had cataract surgeries and still can't see until I get new glasses so I can relate. I will probably be shocked to see how much cleaning I have missed around my house because I couldn't see! May not like some of my color combinations in quilt tops either when I can really see what I did! HA
