Lazy Eye / Amblyopia

RevitalVision is the only FDA approved therapy with specific efficacy claim for vision improvement in adult amblyopia (9+) with no upper age limit. When patching is no longer effective!

Lazy Eye / Amblyopia

The program is indicated for amblyopic age 9 and up, with best corrected vision between 20/30 and 20/200, there is no limitation on refraction. Eye deviation should not exceed 8° prism diopter. The goal of the amblyopia program is to improve best corrected vision.

  • Improves VA (2+ VA lines on average)
  • Improves CS (100% on FACT sine wave on average)
  • Improves Stereo Acuity & Binocular functions


Contra Indication:
  • Eye deviation exceeding 8° prism diopter
  • Diplopia
  • Epilepsy
  • Unstable vision/ vision fluctuations
  • Severe untreated attention disorder
Treatment Criteria:
  • BCVA up to 20/100 (6/30) – Unilateral amblyopia
  • BCVA up to 20/200 (6/60) – Bilateral amblyopia
  • Any amblyogenic background
  • Cognitive intact
  • Motivated to complete 40 training sessions in a 3-month period
Treatment Protocol:
  • Patient has to be best corrected, adapt prior to training, and wear the correction all day through the training period
  • If anisometropia is higher than 3.5 diopters, patient should be prescribed with contact lenses only. (to overcome the Aniseikonia which supports suppression)
  • Training is done while the dominant eye is blurred with a semi-transparent white cover
  • Patient should keep the blurred eye open underneath the cover
  • Bilateral amblyopia – starts with 2 eyes open. After 40 sessions, once the dominant eye gains stable improvement, reset the program and ask the patient to start monocular training to maximize vision in the weaker eye.
  • 40 training sessions
  • Follow up exam is recommended after 20 and 40 sessions


Remark: this is a stand-alone therapy, there is no need to combine it with patching therapy.


Clinical Follow up:
  • BCVA distance
  • Stereo acuity (Randot or Titmus fly)
  • Binocular functions (Worth 4 dot)
  • Contrast Sensitivity (FACT sine wave test) – recommended


Example of patients with a high need for the program includes:
  • Patient missing 1-2 VA lines to qualify for driving license
  • Bilateral amblyopia
  • Loss of vision in the dominant eye due to disease or trauma
  • Late diagnosis of children age 9+
  • Patient missing 1-2 VA lines to qualify for specific work criteria (Pilot/Army/ Police/ Air Traffic Control etc.) 
  • Professional athletes
