Abstract: Disclosed is a method of quantitatively assessing whether the progress of an operation that enlarges a patient's clear vision region is satisfactory. A chromatic vision measurement is carried out on a patient who has received an operation that enlarges the patient's clear vision region, such as an operation that inserts a multi-focal lens into an eye to treat cataracts.
