Vitreoretinal instrument
View Patent ↗An improved instrument for helping to remove subretinal fluid and helping to perform fluid exchanges in vitreoretinal surgery is disclosed. The instrument includes a handle and a probe coupled to the handle. The probe includes a curved distal portion having a closed tip with a smooth surface capable of safely touching the retina.
1. A method of displacing subretinal fluid from a space between a retinal detachment or a retinal tear and a choroid of an eye, comprising the steps of:
providing an vitreoretinal instrument, comprising:
a handle; and
a probe coupled to said handle comprising a curved distal portion made from a flexible plastic, said curved distal portion having a smooth dorsal surface capable of safely touching the retina;
grasping said handle;
disposing said probe within a vitreous cavity of said eye above said retinal detachment or retinal tear with said dorsal surface proximate an inner surface of said retina; and
moving said handle so that said dorsal surface contacts said inner surface of said retina and displaces subretinal fluid.
2. The method of claim 1 wherein said probe comprises an optical fiber disposed in said handle and said curved portion, and further comprising the step of transmitting light from said optical fiber and said curved portion to an interior of said eye.
