Correction of astigmatism with OKVision® FUSION NEW toric soft contact lenses: Fitting algorithm

Abstract

Uncorrected astigmatism is one of the most common causes of reduced visual acuity in the world population. The optical system of the eye, in which the presence of clinically significant astigmatism (more than 1.0 D) is detected, is quite common. In the absence of adequate correction or inadequate diagnosis, astigmatism significantly reduces the uncorrected visual acuity of patients, which affects their quality of life. Eyeglass and contact vision correction are the most common methods of non-surgical correction of ametropia. However, according to the data of foreign and Russian studies of the contact astigmatism correction market, the share of toric lenses fitting is only a small part among all prescriptions.

This article is devoted to detailing of the fitting algorithm of new toric soft contact lenses manufactured by OKVision® Fusion NEW Toric and aims to help optometrists to fit this type of lenses more confidently, which in turn will help users to obtain full- fledged vision correction.
