Adaptation Time

  • Allow patients to adapt to the lenses for 5 to 10 minutes while experiencing real-world vision outside the exam room.
  • If the patient is satisfied with vision at distance and near, dispense the initial diagnostic lenses.

NOTE: If the patient has a visual concern at distance or near, proceed to Distance Over-Refraction.

Distance Over-Refraction

  • Any over-refraction should be done outside of the phoropter with the patient viewing a distant target under binocular conditions. Without occulsion, perform a monocular distance over-refraction for each eye.
  • Begin by placing additional plus in 0.25D steps until the patient reports a decline in the quality of the distance vision. Try to over-refract with minus lenses only after plus lenses are rejected.
  • Verify results binocularly at distance and near, utilizing hand-held lenses and everyday viewing objects instead of acuity charts.
  • Insert the new trial lenses, keeping the ADD the same, and re-evaluate distance and near-vision binocularly.

NOTE: If distance and near vision are functional for the patient after the Distance Over-Refraction, dispense the new lenses for a one- to two-week, real-world experience and adaptation, and schedule a Follow-Up Visit.
