STRENGTH OF THE CHORIORETINAL ADHESION AFTER HIGH-FREQUENCY ELECTROWELDING IN COMPARISON WITH DIODE LASER COAGULATION
Umanets N. N.
Odessa, Ukraine
Strength of the chorioretinal adhesion after high-frequency electrowelding and diode laser coagulation were studied in the experiment on 52 rabbits (104 eyes) in different periods after intervention.
As a result of the study it is established that high-frequency welding of the biological tissues with the parameters — voltage 14—16 W, current strength up to 0.1A, exposure — 1—2 sec, frequency — 66 kHz provides the increase of the chorioretinal adhesion immediately after the effect of the electric current more than 2 times compared with the control group — the effort for tearing off the retina was 224 mg while in the control group (after the influence of diode laser coagulation) it was 105 mg.
