Can a doctor induce a minor regression 4 months post PRK, non surgically to correct for slight over correction?

At four months post op PRK your result may still change as healing continues. However, there is no "non-surgical" means of correction of your refractive status. If after six months your reading issues persist a prk engagement procedure may be considered. Alternatively you might wait for final FDA approval for a corneal inlay known as Kamra. Using small aperture optics this has been shown to correct reading vision without producing an adverse effect on distance acuity.
