Post-refraction procedures, such as the ophthalmoscopy and Mallett unit testing, are usually performed after the optimum refractive correction has been determined. Some procedures, such as those assessing oculomotor balance, may be conducted pre- and post-refraction to determine if the new refractive correction has had any effect on the results of those tests. Other procedures may be conducted post-refraction in order not to negatively affect the refraction procedures, such as contact tonometry and fundoscopy through dilated pupils.
