In my practice, I wait 3 months after nearsighted LASIK to let the eyes heal and settle down before considering an enhancement. Depending on the total residual prescription at that time (i.e., plano-0.25 or -0.50-0.25), as well your satisfaction and other test results I would make a recommendation for or against enhancement. We wait because we see improvement in many over that time. I recommend patience, keeping your appointments, and not getting too hung up on numbers. For example, the 0.25 in and of itself is a trivial amount of astigmatism. The fact that you don't think your vision is very sharp is NOT trivial and the most important measure of success.
The good news is that if you don't improve enhancements are safe if you do need one.

Your correction is too large for LASIK or PRK. Your best option is likely an ICL, which can correct considerably more myopia than LASIK

According to your limited records, you had LASEK (basically the same as PRK) with can take longer to completely heal. I recommend aggressively treating the dry eye with the drops you're using, Omega 3 oral supplementation (I prefer high dose i.e., 4 grams/day), and avoidance of drying activities such as fans over beds, long computer use without breaks and the like. Restasis or punctal plugs may also help. The best healer in the situations if often time.

I'd need to see the results of your left eye measurements to know for sure, but you may benefit from an enhancement. I perform these not before 3 months and when the vision has completely stabilized.
Your left preop prescription was fairly large, and this does increase the chance of needing enhancement by a small margin. Slight devistions from intended results are generally caused by slight variability in tissue response to the laser rather than measurement errors.

I don't recommend LASIK for you. Your best procedure would be an ICL (implantable contact lens) or a refractive lens exchange, depending on your age.
