Well, I went to see the eye surgeon.
The upshot of my meeting was that I’m not going to have an operation to correct my doublevision. I decided that it wasn’t worth it because I have what he termed a “complex squint” and any correction to my doublevision to the left would be offset by new problems to the right. The surgeon said he could perform the operation if I wanted it and give me single vision looking straight ahead but he couldn’t cure me.
I decided that I would rather stick with what I’m used to and avoid an unpleasant operation with its uncertain aftermath.
There is, of course, the consideration that my eye movements could be affected again by a future relapse and undo everything the surgeon did.
At least I can stare out the monster with my prism lenses. They’re not perfect, but they iron out my straight-ahead vision when I need them to. They have their drawbacks in that they’re not very good with computer screens as they blur the text and they’re not very good with bright light (direct sun or car headlights) as they tend to splinter any brightness into vertical lines.
The extent of my problems as they stand is as follows: I see double from the centre (I hold my head slightly off kilter to make up for this, apparently) and to the left. This gets worse as I look further to the left and I get a little nystagmus (flickering eyes) to the extreme left.
Rather than screw up one eye, I either turn my head or trust the image from my right eye and mentally switch off my left eye image when I look left, which is odd because my left eye is a little bit sharper than my right one..
I see single, slightly off centre to the right and then it doesn’t take long before I get a textbook case of very noticeable nystagmus (surgeon to student yesterday: “take a look and note that for your finals”) coupled with not so extreme doublevision to the extreme right.
When my eyes look up and down in the single vision field, they’re fine and when I look left and right, my eyes travel at slightly different speeds – there’s a little bit of lag in my left eye.
If the truth be known, I have to say the meeting answered a lot of questions and I’m relieved I don’t have to go through all that.
