Used when cataracts, corneal scars or edema, and vitreous haze prevent a patient from reading an acuity chart and prevents the doctor from seeing the macula. Learn macular acuity at the slit lamp in patients with significant cataract, corneal edema, or vitreous haze. Learn macular acuity in 10 seconds pre-operatively, not as a surprise post-operatively. Is not significantly affected by moderate cataracts, severe corneal edema, or vitreous haze. Visual target is the white blood cells in the macula. Seeing these cells equals 20/40 or better potential visual acuity. World's most accurate macular test with 94% accuracy.* This is the missing diagnostic test that will change the way eyes with poor vision are examined and treated. Demonstration to the patient is dramatic. Patients see inside their own eyes and see their white blood cells 'jump' as their heart beats. LASTS A LIFETIME! Inexpensive filters don't work.
