Using Psychophysics Methods for Quantitative Assessment of Sensory Binocular Imbalance After Cataract Surgery
Using binocular phase combination paradigms and binocular rivalry paradigms to quantitatively assess the degree of sensory binocular imbalance in patients following cataract surgery, investigating the relationship between unilateral and bilateral cataracts in children and varying severities of cataracts in adults with respect to sensory ocular dominance, and forecasting the postoperative quality of life for patients.
Study Type
OBSERVATIONAL
Enrollment
96
Ophthalmology and Optometry Hospital, Wenzhou

Perceptual Phase
The perceptual phase when the interocular contrast between the two eyes is 1.
Time frame: Each subject undergoes a one-time examination, which lasts for about a year. Each subject's participation in this clinical study will take approximately 0.5 hour.
Ocular Dominance Index (ODI)
The ratio of the total time spent by the observer reporting complete dominance of visual stimuli presented to the dominant or non-dominant eye.
Time frame: Each subject undergoes a one-time examination, which lasts for about a year. Each subject's participation in this clinical study will take approximately 0.5 hour.
