Abstract

FIELD: medicine, ophthalmology. SUBSTANCE: method of varying focal power of artificial lens involves periodical compression of an artificial lens end-face portion. The artificial lens is characterized in that the lens is provided with a support ring and a circular groove formed on its end-face surface, the support ring being made of shape memory material. EFFECT: enhanced efficiency. 4 cl, 5 dwg

Description

 The invention relates to medicine / ophthalmology and can be used to temporarily increase visual acuity.

 A known method of measuring the optical power of the lens with the introduction of an artificial lens in the eye.

 Known and artificial lens / containing a lens and a support ring / located on the body of the lens.

 A disadvantage of the known technical solutions is that visual acuity cannot be controlled after the introduction of an artificial lens into the eye.

 The aim of the invention is to simplify while providing a temporary change in the optical power of the lens.

 The invention consists in the following. If necessary, increase farsightedness change the focal length of the artificial lens, squeezing the body of the lens with radial forces.

 To return the focal length to its original position / remove radial forces.

 Radial forces occur during compression of the ring / lens placed on the body. The ring is made of a material / having a reversible shape memory / for example NI-TI, Cu-Al-Zn. Before installation on the lens, the ring is subjected to preliminary heat treatment — quenching in a compressed position in the state of the high-temperature phase and deformation in the expanded position in the state of low-temperature martensitic transformation.

 In FIG. 1 shows the lens in the initial position / incision; in FIG. 2 - the lens in a compressed position / incision; in FIG. 3 - ring / top view; in FIG. 4 is a diagram of the lens in the eye; in FIG. 5 - ring <-shaped / section.

 An example of the method.

 To temporarily increase farsightedness, the ring is heated / as a result, the body of the lens is deformed (compressed) and its focal length changes.

The heating rings carry / instance / location before the eyes of a heated body with a temperature above normal human body (36/6 C) / through which the heated ambient air will heat the eye or temporary lifting of the body temperature / eg to 37 ° C. / or fed to the warm mask air. To return the focal length to its original position, remove the heat source, etc.

 The device contains an artificial lens 1 / on the body of which is placed a ring 2 of material with a reversible shape memory / having at least three internal spikes 3 and supporting elements 4.

 The device operates as follows. When heated / the ring 2 contracts and compresses the elastic body of the artificial lens 1 / changing its focal length / hence / increasing farsightedness. The spikes 3 prevent the ring 2 from slipping off the body of the lens 1. The supporting elements 4 hold the lens in the eye.

 To prevent the ring 2 from popping up, an annular groove is made on the lens body or the ring itself is <-shaped / thereby covering the lens body.

Claims (3)

 1. The method of changing the optical power of the lens of an artificial lens by thermal action in the radial direction on the lens body, characterized in that, in order to simplify while simultaneously providing a temporary change in the optical power of the lens, the radial effect is carried out periodically.
 2. An artificial lens containing a lens and a support ring, characterized in that, in order to simplify while simultaneously providing a temporary change in the optical power of the lens, the support ring is made of a material with a reversible shape memory.
 3. The lens according to claim 2, characterized in that the end surface of the lens is provided with an annular groove.
