FIELD: medicine.
SUBSTANCE: invention refers to ophthalmology. An intracorneal lens comprises an optical portion having front, back surfaces, an optical axis and a non-optical axis concentric with an optical portion outside the optical portion. The lens is made of a transparent material biocompatible with the corneal tissue. It is demountable. The non-optical portion has a central hole the diameter of which corresponds to the diameter of the optical portion, while an inner portion of the non-optical portion is congruent with an end surface of the optical portion.
EFFECT: using the given invention enables reducing the rate of undesired visual postoperative effects, such as light scattering circles, gating, and enabling recurrent surgical intervention for the correction of presbyopia progression, as well as promotes extending the range of intracorneal lenses.
