Some patients are eligible for, and do choose the option of an enhancement procedure after previous Lasik. You should discuss this with your Ophthalmologist after a detailed clinical examination.
However, you should consider that a small degree of residual myopia is actually useful for a person in your circumstance as it helps you with your near vision. In fact for patients who are presbyopic and considering Lasik, we commonly intentionally leave them under corrected in the non-dominant eye, in order to give them functional near / distance vision in both eyes (a technique called mono-vision).
Again, you should consider your specific situation with your attending Ophthalmologist. Best of luck!
