| It's not unusual at all for near vision to be affected after eye surgery, and vice versa. In fact, the doctor should have advised prior to it that it could have that effect, and will offer to do one eye for far sightedness and one for nearsightedness. The dominant eye gets the far vision upgrade, and the weaker of the two gets the near vision upgrade. Often they'll only do one eye and wait to see how the other is affected before proceeding, or you may opt to wear a contact in the reading eye. Also, when you have eye surgery for nearsightedness it tends to accelerate the degradation process of the near vision caused by increasing age. Still, having the eyes corrected to 20/20 or better (mine was 20/16 before sudden diagnosis of diabetes has taken all that good fortune away and gone blurry). Now I'm waiting to see if it returns as they say. I've been under BG control for almost a month, and still no improvement.
My understanding with laser/lasik, and any other eye surgery will not be approved of if you have diabetes because of the effect it has on the vision changing. So whatever corrective surgery you have could have adverse effects. It's possible they would consider the surgery if after a retinopathy scan reveals no damage to the eye has been caused by diabetes.  |
