Time frame: 20- Minutes Post-Lens Fitting
Visual acuity on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 meters) under high luminance high contrast, high luminance low contrast and low luminance high contrast with distance goggles using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. Letter-by-letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR value of 0.0 is equivalent to 20/20 Snellen vision.
Time frame: 20- Minutes Post-Lens Fitting
Visual acuity on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at near (40 cm) under High luminance low contrast and low luminance high contrast with distance goggles using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. Letter-by-letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR value of 0.0 is equivalent to 20/20 Snellen vision.
Time frame: 20- Minutes Post-Lens Fitting
Quantitative Visual Acuity (qVA) was measured at distance (4 meter) under low room illumination (4 lux), low luminance, high contrast conditions in the right eye only and in both eyes using AST Sentio vision Testing System. During testing 25 triplets of test letters were displayed on a large stationary monitor (118 CM), the operator recorded the patient's responses using the remote (Android Tablet). After a testing session had been completed the software calculated the VA threshold. VA threshold was defined as the logMAR stimulus size at which the expected probability of correct letter identification is 66%. when both eyes are measured. The average median VA threshold was reported for each lens. Lower values indicate better vision.
Time frame: 20- Minutes Post-Lens Fitting
Area under the log Curve was measured at 1.5, 3, 6, 12 and 18 cycles per degree (cpd) in the right eye only and in both eyes using AST Sentio vision Testing System. During testing 25 triplets of test letters were displayed on a large stationary monitor (118 CM), the operator recorded the patient's responses using the remote (Android Tablet). After a testing session had been completed the software calculated the Area under the log contrast sensitivity function from 1.5 cpd to 18 cpd. The average area under the log curve was reported for each lens. Higher values indicate better vision. Number of eyes is 50 when both eyes are measured.
