Presbyopia is a natural process that typically occurs in the 40’s and reduces ones ability to read when vision is corrected for distance. This problem is a frustrating one, especially for those who enjoy contact lenses. When contacts are used to correct far away vision in someone who is presbyopic, additional options are needed to allow comfortable reading. Over-the-counter reading glasses and mono vision are two options that offer both advantages and compromise. Multifocal contacts continue to improve in viability but typical “one-size-fits-all” lenses don’t offer options for patients with astigmatism. It is important to remember that, unlike bifocal or progressive glasses where distance and near vision can be put in different parts of the lens, contact lenses are stable on the eye and all powers must be contained in a small pupil-sized region, making the task of crisp vision at all distances much more difficult. Here we will discuss options for patients with astigmatism who need distance and near correction and desire binocular vision free from reading glasses:
Custom soft multifocal toric lenses
Unlike one-size-fits all soft contact lenses, custom soft lenses are made based on a patients corneal parameters including diameter, curvature and eccentricity (rate of flattening). Not only is the fit customized to improve comfort, the optics are also made to specifically match the patients prescription. These lenses are made-to-order and therefore all specifications are customizable, even the material the lens is made from.
