Abstract

Purpose: To compare the visual outcome of Soflens Daily Disposables and Soflens Daily Disposable for Astigmatism (Bausch & Lomb, Rochester, NY, USA) when worn by subjects with low astigmatism. Methods: Forty-one subjects (aged 19 to 40years) with myopia between 0.50D to 6.00D and astigmatism not more than -1.25D in at least one eye were recruited and fitted with spherical and toric soft contact lenses in this double-masked, non-dispensing cross-over study. High and low contrast logMAR visual acuities were measured over the lenses. At the end of the study, each subject was asked to complete a questionnaire on vision, initial comfort and ease of handling of the two lens types. Results: Monocular and binocular high and low contrast logMAR visual acuities were significantly better with the toric lenses compared with the spherical lenses (p < 0.01). Results from the questionnaire showed a significantly higher grade for vision with the toric lenses than with the spherical lenses (p = 0.003) but no significant differences in initial comfort and ease of handling between spherical and toric lenses (p > 0.21). Conclusions: The results of the present study show that both subjective and objective vision in myopic subjects with low astigmatism improves significantly when corrected with toric lenses compared with spherical lenses.
