I have some family history of glaucoma, so I get tested every year. I really dislike the eye puffs and the drops my Dr used. I see an ad for another local Dr who has a new rebound tonometer that measures intraocular pressure without the air puffs or drops. I really like my eye Dr and don't want to switch, but I hate the puffs and drops and felt a little unsafe driving home afterward and felt dizzy and couldn't read for hours. does anyone know if this tonometer is as accurate at measuring IOP?
