Went back for my 2nd check up on 20th Jan. Saw another optician, who was much more thorough. Said I'm only +25 now in the corrected eye (was +1.50 at last check-up). She also said it can take circa 3/6 months for the vision to be perfect. It's now been circa 2 months since I had one eye corrected and overall I'm very happy with the outcome. I am looking at getting my other eye done in April.
