My eye doctor and the surgeon had no problem with my getting LASIK with type 1. The only concerns were that my a1c was stable at below 7.5% for at least a year, that I didn't experience wild blood sugar-related variations in my vision, and that I passed all of the other tests required for everyone else. My current ophthalmologist has no problem with my having had LASIK either, and she's an expert retinologist. The retinas, which are typically where diabetes complications show up in the eyes, are completely different and separate from the LASIK procedure which focuses on the lenses and corneas.
I would talk to a LASIK surgeon with at least 50,000 procedures to get a real sense of what the surgery entails. I wouldn't trust my endo, who knows a lot about endo things, to be last word on my eyes. I think it helps if you haven't had diabetes for that long so that healing isn't impacted, but that's just my hunch. No one ever told me that. I was 3 years post-diagnosis.
Everyone agreed that, in my case, LASIK was the safest option between glasses and contacts. I was a lazy contact wearer and slept in them too often, and my prescription was so strong that glasses often distorted my vision because of their thickness. LASIK gave me my best shot at healthy, long term vision correction. Since I was so blind, having to rely on glasses or contacts was more of a risk, especially overnight.
It certainly wasn't a decision I made lightly since someone was going to cut my eyes open and then shoot lasers at them for a minute each. I was actually approved for the surgery a year before I went ahead and scheduled it, so I completely support taking your time, making sure your levels are as stable as possible, and being 100% sure that comfortable with your surgeon and the risk. To me, the benefits far outweighed the risk, and it helped that I could positively influence the risks by keeping tight control on my blood sugar.
All that said, the greatest LASIK in the world won't stop you from eventually going farsighted with old age, so you'll only be free from glasses for so long!
