Since May 1993 to February 1995 we have used "DK-LINE" OPSIA in 137 patients in whom were 161 procedures on 141 eyes performed. It was used in 116 retinal detachments, 29 of them were posttraumatic. 28x in the eyes with proliferative diabetic retinopathy, 8x by injuries of the posterior segment of the eye, 5x in dislocated lenses and 3x by the removal of subretinal membranes. At the end of retinal detachment surgery was retina attached in 94.2%. Peroperatively we recorded subretinal migration of PFCL in 16 cases. 13x was removed peroperatively and 3x later by the reoperations. In three aphakic eyes we recorded postoperatively small bubble of PFCL at the bottom of the anterior chamber. From two of them was fully removed by paracenthesis and from the third by the reoperation. Only 1x we used an internal tamponade in duration of 5 day. We recorded serious sero-fibrinous exudation in the anterior chamber and in the vitreous cavity over the level of PFCL.
