FIELD: medicine. ^ SUBSTANCE: method involves producing two diametrically arranged superficial scleral flaps (SSF) the basis to limb. Middle layer sclera strip (MLSS) is cut under each SSF to 1/3 of sclera thickness, arranging the MLSS symmetrically relative to longitudinal axis of superficial scleral flap with its base turned towards the limb. The anterior chamber is exposed along notch done between each SSF and MLSS. Next to it, lower MLSS is sutured with fixing suture near its free end. Needle with thread attached to it is introduced into the anterior chamber under iris through the lower scleral incision at 18 o'clock position. enter Posterior chamber intraocular lens (PCIOL) is introduced through incision for making implantation into the anterior chamber, placing the lower base member in the lower pupil zone. Needle and thread are brought through the lower base member above frontal PCIOL surface and exit from eye cavity is made through the implantation incision. The free end of the lower MLSS is brought through lower basic member of the PCIOL. The lower PCIOL half is shifted under iris. The needle is turned, introduced again into the anterior chamber, brought in the opposite direction and brought out under the iris from eye cavity through the lower scleral incision under the lower SSF. The lower MLSS is brought out from eye cavity by pulling the thread. Further, fixing suture is applied on the free end of the upper MLSS. Needle and thread are introduced into the eye cavity through the upper scleral incision under SSF, bringing it under the iris towards the upper pupil part. Upper PCIOL base member is brought to the same place, the needle is brought through it and out under the iris through the lower scleral incision from the eye cavity under the lower SSF. The free upper MLSS end is brought through the upper base element of PCIOL by pulling the thread. The needle is turned, introduced again into the eye cavity under the iris above the frontal PCIOL surface, and brought through the upper scleral incision under the upper SSF. The PCIOL is centered. The upper MLSS is brought out through upper scleral incision by pulling up the thread. Both MLSS are placed in corresponding scleral bed, and attached to adjacent sclera with resolving suture. Fixing sutures are removed from free MLSS ends and SSF is sutured to adjacent sclera with interrupted sutures. The implantation incision is tightly sealed. ^ EFFECT: reliable elastic PCIOL fastening; firm adhesion to adjacent sclera; excluded suture eruption risk. |
