This course is designed to teach and reinforce ophthalmic personnel and optician skills that are necessary in performing both retinoscopy and refracting of doctor’s patients. Instructor will identify and explain different starting points for a refraction including when each of these are used. Also discussed are helpful and efficient techniques in retinoscopy refinement which objective as well as subjective refinement of a patient’s prescription in an attempt to give them the most useful eyeglasses or contact lenses.
Upon completion of this course, the participant should be able to: discuss the starting points for a refraction; explain the axis labeling methods of retinoscopy; distinguish between different retinoscopic reflexes; confirm retinoscopy results; explain the steps of the subjective refraction refinement; explain the use of the Jackson Cross Cylinder; discuss uses of balancing tests of refraction values; demonstrate ways to check a patient’s ADD; identify uses of the Maddox Rod and/or Risley Prism.
