Refined procedure for ophthalmic aberration measurement

A method for improving accuracy of measurements from an auto-refractometer (100) to provide an optimal prescription for a patient's vision, the method comprising:

• a. measuring, by the auto-refractometer (100), a measurement of the patient's vision in an eye;
• b. applying, by an auto-phoropter (200) operatively coupled to the auto-refractometer (100), a correction within a line of sight between the eye and the auto-refractometer;
• wherein the correction comprises an increase in visual acuity based on a correction factor;
• and
• c. repeating steps a-b until the patient's vision has been optimally corrected.

A system for improving accuracy of measurements from an auto-refractometer (100) to provide an optimal prescription for a patient's vision, the system comprising:

• a. the auto-refractometer (100);
• b. an auto-phoropter (200) operatively coupled to the auto-refractometer (100);
• and
• c. a computing device communicatively coupled to the auto-refractometer (100) and the auto-phoropter (200), comprising a processor capable of executing computer-readable instructions, and a memory component comprising a plurality of computer-readable instructions for:
• i. measuring along a line of sight, by the auto-refractometer (100), an initial measurement of the patient's prescription;
• wherein the initial measurement comprises 0 diopter correction by the auto-phoropter;
• ii. applying, by the auto-phoropter (200), an initial correction along the line of sight to generate an initial result;
• iii. determining whether the initial correction has optimally corrected the patient's vision;
• iv. applying, by the auto-phoropter (200), if the initial correction has not optimally corrected the patient's vision, an updated fractional correction along the line of sight to replace the previous correction;
• wherein the updated fractional correction comprises the product of the previous prescription measurement and a correction factor;
• v. measuring, by the auto-refractometer (100), an updated prescription measurement along the line of sight, accounting for the updated fractional correction;
• vi. applying, by the auto-phoropter (200) an updated full correction along the line of sight, wherein the updated full correction corresponds to the updated prescription measurement;
• vii. determining whether the updated full correction has optimally corrected the patient's vision;
• viii. repeating, if the updated full correction has not optimally corrected the patient's vision, steps iv-vii until the patient's vision has been optimally corrected.
