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

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.
