简要总结
The study objective was to compare short-term clinical performance data of two toric contact lenses.
详细描述
The aim of this non-dispensing fitting study was to evaluate the short-term clinical performance of a monthly toric contact lens when compared to a daily disposable toric contact lens after 15 minutes of daily wear each.
