For whom to fit toric contact lenses?
According to statistics, about 45% of future contact lens wearers have astigmatism 0.75 diopters or more. Percentage of toric contact lenses fitting is significantly lower. Astigmatism to 0,5 diopter is considered the most physiological and it is not needs to correct it. Also in this area, the requirements of patients on vision can vary significantly. We all know that sometimes improves visual acuity also cylinder 0.25 diopter in eyeglass correction.
Astigmatism correction with toric contact lenses
Low and medium astigmatism the patient is able to partially correct by increased accommodation effort. However, this may lead ultimately to asthenopic difficulties, particularly where increased accommodation improves vision. In children can then lead uncorrected astigmatism with axes inclined to the torticollis and scoliosis due to inclination of the head.
