I had strabismus
surgery for a right hyperphoria
four days ago. I had eyestrain, headaches, and intermittent double vision
before the surgery. The surgeon basically resected the right inferior rectus by 4mm. During the post-op checkup, the doctor found 0 PD hyperphoria and 20 PD exophoria
However, I notice that I still get headaches and eyestrain post-surgery. Studying for class is nearly impossible unless I close an eye. I can see two possibilities for why this is so: either it is the exophoria that is causing it, or the surgeon overcorrected.
The reason why I suspect that latter, is that during the past few days, when I wake up in the morning, I notice double vision for the first 10 minutes or so. The double vision is such that the image from the right eye is above that of the left eye (right hypo). After 10 minutes or so of having both eyes open, my vision returns to single.
This leads me to be concerned about the possibility that the surgeon overcorrected the right hyperphoria, and my eyes now have to put extra effort into keeping the image single, negating the effectiveness of the surgery.
Does this transient morning double vision suggest overcorrection? Or is it to be expected after such a surgery?
