Should I find out the kind of lens that the Dr. will be putting in? I know it won't be a Crystalens but are there different brands etc. and is that something I should know? My Dr. also said, once the lens is in it's in, no replacing it, like say if Chrystalens comes out with a lens to correct or help astigmatism. I feel as if I haven't been given much info but I know this is a reputable Dr. I went in three weeks ago and was told to stop wearing my contacts for three weeks so my eyes could return to normal, and then I went in today and they did two tests and surgery is now scheduled. That's it? They have all the info they need? I do have a brain tumor, meningioma, under 3cm. I had SRS for it, one of my main symptoms besides headache were visual disturbances, they were called, ocular migraines, or migraine with aura, but to me they relate directly to my tumor which is on the sagittal sinus in the posterior third in the parietal lobe, I think the ocular events have everything to do with blood flow, any thoughts on this? I am very excited to see better than I ever have, I will be able to still wear contacts too right? Thanks for any info.
