Background: Dynamic Visual acuity is described as the visual acuity which is evaluated with motion; which required in Ophthalmic and Optometric routine eye evaluation. LogMAR chart is widely used in ophthalmic and Optometric investigation, although it’s an excellent visual acuity chart but its unable to evaluate dynamic visual acuity. Aim: To compare the effectiveness of dynamic Optotype visual acuity chart and logMAR visual acuity chart on cataract patient. Methodology: This was a descriptive study limited to individual aged 50 years & above who were selected for cataract surgery & brought to Sankara eye hospital Ludhiana from different locations of Punjab. Patient excluded from the study were those who had surgery for traumatic cataract, pterygium, corneal pathology & retinal pathology. Data was collected over 3-month period from January 2020 to March 2020. The case sheet of Sankara eye hospital was used to record the following: Demographic data, visual acuity, current prescription & other existing ocular pathology. Result: 75 subjects were included for the study out of which 35 (46.67%) were male and 40 (53.34%) were female. The mean age of the subjects was 63.8 ± 6.12 years. Out of the 92 eyes, 20 were prescribed glasses and 72 were left uncorrected at the baseline. The prescribed group at baseline was considered as Controls and the non-prescribed group at baseline was considered as Cases. Conclusion: The result of dynamic optotype visual acuity and LogMAR are similar in visual acuity measurements. There is hardly any difference between both optotypes. As this study was performed. The visual acuity was almost identical in LogMAR and dynamic visual acuity test. The time taken to perform dynamic optotype chart was less. So, the study concludes that dynamic optotype is faster visual acuity chart which is equivalent to LogMAR and productive with illiterate population.
