I had cataract surgery (monofocus) in one eye in late January. After 6 weeks, I now have new prescription lenses for both eyes, which are 3.25 diopters different. I am a regular and quite good tennis player, and I am having great difficulty playing as well as I was accustomed. The best way to discribe the problem is that I am having trouble focusing on moving objects. I can see very well at a stationary scene, but am getting hit by balls that I used to hit well. Is this a condition that I will get used to over time, or is the imbalance between the focal lengths in my eyes beyond the limit that the brain can adjust to? If I am forced to give up tennis, at my age, I will probably never regain it, and it will limit my options for getting exercise. My insurance will not approve getting the other eye done until my vision is bad enough in that eye.
