摘要：
The present disclosure relates to the use of contact lenses for treating one or more ophthalmologic conditions. In some embodiments, the contact lenses may be used to treat presbyopia, induced myopia, computer vision syndrome (CVS), insufficient accommodation, or a condition associated with insufficient accommodation. The contact lens may include a number of regions having different geometries (e.g., curvature, width, diameter) depending on the flattest keratonomy of the cornea to achieve a suitable fit. For example, the contact lens may include an optic zone surrounded by an inner peripheral region and an outer peripheral region surrounding the inner peripheral region, each exhibiting varying degrees of curvature. The fitted contact lens may be selected based on a measured sagittal depth and/or eccentricity of the cornea. When fitted, an appropriate amount of fluid may accumulate between the cornea of the eye and the contact lens. In addition, the lens may exhibit a sufficient amount of apical clearance such that when the wearer blinks, the lens moves no more than 1 mm on the eye. Further, the lens and the eye may be mutually structured such that bubbles greater than 0.5 mm in diameter are prevented from forming between the contact lens and the eye. The contact lens may be used in combination with a suitable bioactive agent providing for enhanced visual correction.
