FIELD: medicine; medical engineering.
SUBSTANCE: device is manufactured as monolith disk-shaped diaphragm from flexible material. It has optical and haptic part. The haptic one has colored ring having internal diameter of 3.0-4.5 mm and external diameter of 9.0-10.0 mm, and supporting arc-shaped closed members as vertices of a figure symmetrically or asymmetrically arranged relative to pentagonal star rotation axis within a circle of 11.0-13.5 mm large diameter. To make point touch with surrounding tissues, the supporting members have rounded or sharp ends. Method involves applying the supporting members of haptic part for fixing iridolenticular diaphragm depending on whether lens bursa, capsule or iris residues are available or unavailable in the eye. The iridolenticular diaphragm is implanted via small tunnel incision in the cornea or sclera. Capsule bursa residue being available in the eye, supporting members of the iridolenticular diaphragm under implantation are leaned against the residues without additionally fixing them with sutures and thrust into the ciliary sulcus. Iris residues being available in meridians, closed ends of the iridolenticular diaphragm haptic part supporting members are preliminarily cut off and the supporting members are fixed in the meridians immediately to the iris in clips-like manner. No iris residues being available, the members are additionally sutured to sclera in one or two points. Intact capsule bursa being available, iridolenticular diaphragm is implanted after having completely cut-off the supporting members of the haptic part. Complete or partial lack of capsule or iris support being the case, iridolenticular diaphragm is implanted with suture fixation to sclera being used after having in advance built three sclera pockets in meridians corresponding to the supporting members arrangement in the haptic part of the iridolenticular diaphragm.
EFFECT: stable position and reliable diaphragm fixation; reduced risk of pre- and postoperative complications.
