To observe the performance of clinical fitting of the dynamically stabilized toric soft contact lenses and discuss the relationship of the amount of the rotation and stability with the cylinder amount, axis and the time.
One hundred and ninety one astigmatic volunteers were fit with the dynamically stabilized toric soft contact lenses. The corrected visual acuity of the right eyes, fitting evaluation, the amount of rotation, the stability, the subjects’ feeling and the analysis of safety were recorded.
The centrations of 156 lenses(81.68%)were perfect and the movements of 140 lenses(83.3%)were great. The coverages of all lenses were good. The temporal rotation of 0~5 degree amount was most common, totally 40 lenses(20.94%), and the stabilities of 143 lenses were within 0~5 degrees(74.87%).However the amounts of astigmatism had great effect on the amounts of rotation of the lenses in the 1-minute and 3-minute fitting evaluation (P=0.024 and 0.015 for 1 and 3 min, respectively), but not in the 15-minute evaluation. Different amounts of astigmatism didn’t affect the stability of the lenses. The axis of the cylinder and the evaluation time were not related to the amount of rotation and the stability of the lenses. During the first fitting, 106 subjects reported mild and medium foreign body sensation(55.50%), and 145 subjects took it easy to fit the contact lenses(75.92%). During the 3-month follow-up, none obvious eye abnormalities were found.
Based on the reasonable enrollment, the dynamically stabilized toric soft contact lenses could provide effective, safe and comfortable correction for the astigmatic patients.
