Diluent for perfluorocarbons employed for retinal unfolding (unfolding PFCL) and method of treatment
First Claim
Patent Images
1. A method of treating an eye for retinal detachment, comprising the steps of:
- (a) removing a vitreous body from the eye;
(b) introducing into the eye at least one viscous, nonvolatile perfluorocarbon liquid (unfolding PFCL) which causes the retina to again press back against choroid tissue of the eye;
(c) removing the unfolding PFCL from the eye;
(d) introducing into the eye at least one perfluorocarbon liquid (diluent PFCL), different from the unfolding PFCL introduced in step (b), having a low viscosity and volatile at room temperature, with a boiling point between 38°
C. and 100°
C.;
(e) dissolving during a residence time, residual quantities of the unfolding PFCL into the diluent PFCL; and
(f) aspirating the mixture of the diluent PFCL and the therein previously dissolved unfolding PFCL.

Abstract
A diluent for perfluorocarbons used for retinal unfolding (unfolding PFCL), consisting of a perfluorocarbon (diluent PFCL), which has a low viscosity and is volatile at room temperature, with a boiling point between body temperature (about 38° C.) and 100° C., for removing residual quantities of unfolding PFCL from the eye after performance of a retinal unfolding treatment. A method of treatment consisting of introducing into an eye the above diluent for the above purpose.
