Comparative Study of Hyperacuity and Retinometer Tests for the Evaluation of Vision in Patients with Advanced Cataract

摘要

＜正＞ Objective: To investigates the clinical application value of hyperacuity test for evaluating vision through dense cataracts.Methods: Ten normal subjects （20 years） were tested both with Bailey-Lovie type chart and three points vernier acuity test （one of the hyperacuity test） ; and retinometer test were performed preoperatively and postoperatively in 30 patients （31 eyes） with senile cataract. These patients’ lens opacity was classified with LOGS III system.Results: The correlation of vernier acuity and visual acuity of normal subjects is significant. The result of difference compression of pre-surgical and post-surgical vernier acuity of 30 cataract patients is not significant. The correlation of retinometer findings with post-surgical visual acuity shows not statistically significant. Our result shows that there is good correlation between vernier acuity and post-surgical visual acuity.Conclusion: It appears that hyperacuity is a good test for foveal function behind dense cataract and other ocular opa
