Etafilcon A daily disposables reduce upper lid, limbal staining in Asian presbyopes

Refitting presbyopic contact lens wearers of Asian descent with etafilcon A multifocal daily disposable contact lenses resulted in minimal overall staining.
The researchers suggested in the study, “that using a low rigidity contact lens on a daily disposable modality could be beneficial when fitting patients with presbyopia, in particular patients with high eyelid tonus including those of Asian descent.”
The 20 subjects were presbyopic and current soft contact lens wearers of Asian descent.
The upper lid margin staining after 1 month of daily wear with the study contact lenses (1-Day Acuvue Moist Multifocal, Johnson & Johnson Vision Care) was statistically different from the staining after wear of the habitual contact lenses, with a decrease in mean staining of 39% and a decrease in maximum staining of 64%.
The minimal overall staining with the study contact lenses led to 39% less upper eyelid margin and 32% less limbal staining and a similar degree of upper corneal staining than occurred after lens wear with the subjects’ own contact lenses, according to researchers.
“Because of the high preponderance of dry eye amongst presbyopes, material selection is of importance, and consideration should be given to the lens-ocular surface interaction,” they concluded. – by Abigail Sutton
