ABSTRACT
We reviewed soft toric contact lens fitting success in 100 eyes that required greater astigmatic correction than spherical power correction. We found a significantly greater rate of success with lenses having back surface cylinder correction than lenses with front surface cylinder. When back surface optics are used to correct astigmatism with soft toric lenses, the success rate approaches that obtained in random studies of soft lens fitting success.
