Should I get a LASIK enhancement for left eye to reduce monovision discomfort and address the concern of vision regression?

Question

44 yr old analyst had Lasik monovision 7 months ago. (prior PWR - 7.5, CYL -1 both eyes) Achieved targeted Right eye 0 diopter , Left eye - 1.5 diopters after OP. At 3 month post-OP, Right eye regressed to -0.5 and the Left to - 1.75. I feel some depth perception discomfort and blurriness due to dry eyes. 1. How much more regression would occur? 2. Would the amount of monovision cause eye strain and accelerate regression? 3. Is an enhancement worthwhile to improve left eye by 0.5 or 0.75 now?

1. It impossible to predict how much more regression would occur for you. However most patients do not regress more than 2.50D from the target correction.2. Everyone is different in terms of how much monovision they can tolerate. For some, anything beyond a 1.25D difference can cause strain, discomfort, nausea, and headaches. Generally, the larger the amount of monovision, the more difficult it is to adapt.3. It is worthwhile to get an enhancement, if the vision is stable and you are experiencing blur and discomfort. However, I would definitely trial the targeted difference in contacts to ensure adaptation prior.
