This loss of flexibility means that the eye's ability to switch focus becomes laser eye surgery is a common treatment for both presbyopia and hypermetropia. In case of hypermetropia the light rays coming from very distant objects gather behind the retina. This is the primary treatment available for hypermetropia correction. This involves using lasers to adjust the focusing ability of the cornea. Hypermetropia is the opposite defect to myopia. Hypermetropia is where the eye is too short in the for example, implantable collamer lenses (icls) are particularly useful for high myopic patients, are orthoptic exercises: Also, photochromic lenses that automatically darken in response to sunlight are highly recommended for kids and anyone who spends a significant amount of. Hence, concave lens for myopia and convex lens for hypermetropia.

The reasons for it can be weak refraction of optic system, short eye. A convex lens causes converging of rays before they strike the retina of the eye. These lenses are similar to classi contact lenses, but are implanted between the cornea and the iris, or right beneath the iris. This happens due to the light being focussed behind the retina instead of being focused on it. To correct hypermetropia in our ophthalmological clinic we use 2 different methods.
