Purpose
To determine differences in contrast sensitivity (CS) between Asian and European populations patients binocularly implanted with Asqelio™ Trifocal intraocular lenses.
Setting
Oftalvist, Alicante, Spain, and Chang Gung Memorial Hospital, Taoyuan City, Taiwan
Methods
Contrast sensitivity function (CSF) was determined under photopic and mesopic conditions, with and without induced glare using the Clinical Trial Suite (CTS) (M&S Technologies, Niles, IL, USA) system in two groups of patients, Spanish (n=25) and Taiwanese (n=24). Measurements were obtained 6 months after bilateral implantation of Asqelio™ Trifocal IOLs (AST Products, Inc., Billerica, MS, USA).
Results
CS was either within or above normal range for all frequencies except for 12cpd under mesopic conditions with induced glare for both groups, and without induced glare for the Taiwanese group. Mean CS values were higher for the Spanish group for mesopic measurements, both with and without induced glare (except for 1.5cpd with induced glare). Mean CS was higher for the Taiwanese group for measurements taken under photopic conditions both with and without induced glare. Differences were statistically significant under mesopic without induced glare and with induced glare for 12 and 6 cpd (p<0.001). Differences were significant under photopic conditions without glare for 6, 12 and 18 cpd, and with induced glare for 12cpd (p<0.01).
