- What is the best way to correct this patient?
- Is a progressive lens suitable?
- If so, should I set the heights with the eyes in their natural position in primary gaze, or when aligned by occluding the alternate eye?
- Is it better to use a progressive design like the Sola Elan HDV or Shamir Freeframe where the corridor length is computed on the pupil height or should I use a progressive design with a set corridor length?
