What adjustments, if any, do UK optometrists make to the subjective refraction result prior to prescribing?

Aim: To determine whether UK optometrists routinely prescribe the subjective refraction result, or whether adjustments are made to aid patient comfort and adaptation.

Method: A questionnaire was distributed by post and via the internet to UK optometrists. It incorporated eight case scenarios that included information regarding a patient's age, symptoms, habitual refractive correction, subjective refraction and any other pertinent clinical information.
