Subjective refraction and prescribing styles used by UK optometrists

Poor subjective refraction and prescribing techniques were identified; limited measurement of VA to full threshold, risk of over-plusing/under-minusing, limited cylinder power and axis techniques and symptoms often not reconciling with changes in prescription and improvements in VA were observed. The objective prescription, particularly as determined by autorefractors, holds an exaggerated influence over some optometrists. These are elements of everyday optometry, yet require greater emphasis in CPD.
