ABSTRACT:
An ophthalmologic instrument for dissecting scar tissue from adjacent tissue surfaces in a tissue wall of an eye of a patient, in which the instrument has a rigid housing of a size to enter a space in the eye of a patient and be placed to face a scar to be dissected by the instrument. An inflatable balloon is supported in the housing and in an uninflated state the balloon is substantially confined within the housing and faces an opening at the front of the housing. A pressure source is connected to the balloon for inflating the balloon to cause the balloon to extend from the housing. The front portion of the instrument has a shape to dispose the housing in a position to face the scar and be between the tissue surfaces joined by the scar such that when the balloon is inflated, the scar will be dissected and the tissue surfaces will be separated.
