Hi, I was in the same position. Left side Sphenoid Wing Meningioma, growing over my optical nerve as well. (6.4cm x 3.4cm 7.7cm). I started to have speech problems and in my left eye sometimes sharp pain. So I decided to do my second surgery (first surgery 2012) on 1/7/2020 here in Los Angeles. I was scared about my eye side and so other issue which could create a brain surgery, like you mentioned. When I woke up, after a 7 hour surgery, I couldn't believe I could see everything better, after 2 ½ days in the hospital they released, me due to the fact that I was "top-fit". I am so happy I did it. I am 67 years old myself but I did have problems and therefore had to consider the operation. I do know it is a difficult decision....good luck to you!!!
