Although you may have physiologic cupping (normal variant) you are still considered a glaucoma suspect. I would suggest continued follow up and testing with your ophthalmologist
Your vision should be stable at this point. There is no need to worry and depending on your age your final refraction may work to your advantage. If you are over 40 or approaching it I would not consider further surgery as you numbers would assist you in avoiding reading glasses. You may want to consider a pair of night driving glasses. As always, you should discuss this with your doctor.
