Jason, perhaps you have seen prior posts from me. I also had a meningioma, 2.7 centimeters,
1/16th of an inch from my optic nerve. The neurosurgeon at UCSF was able to remove it all when two other neuro doctors said the location was too risky. Resection (removal of the tumor) is always preferred, so you are "lucky" that you were given that choice. You are young and will do well. I was 71 when my meningioma was removed 8 months ago. The craniotomy was not the nightmare I was worried it would be. I was in the hospital 2 days, not even in the intensive care unit, and except for whatever pain meds they gave me during the surgery I was only on tylenol. I did have double vision for three months after my surgery, not because of damage to my optic nerve, but rather my cranial nerve #4 was compromised in some way. Good luck to you and I am sure you'll get to see your kids graduate and play with a passel of grandchildren some day.
