Abstract
Systems, processes, and computer program products may be used to perform retinal surgery. In particular implementations, a system, a process, and a computer program product may include the ability to inject a retina manipulation fluid into an eye through an injection/extraction system and apply negative pressure to the injection/extraction system to facilitate extraction of fluid from the eye. The system, the process, and the computer program product may also include the ability to adjust the applied negative pressure.
Claims19
A system comprising:
- an injection and extraction system adapted to inject a retina manipulation fluid into an eye through a first channel and extract fluid from the eye through a second channel, the first channel extending distally beyond the second channel to form an annular opening between the first channel and the second channel;
- a fluid extraction system adapted to apply negative pressure to the injection and extraction system to facilitate fluid extraction;
- a computer system adapted to adjust the negative pressure applied by the fluid extraction system, and
- an infusion system adapted to inject infusion fluid to maintain the shape of the eye undergoing retinal surgery.
A method, comprising:
- injecting a retina manipulation fluid into an eye through a first channel of an injection and extraction system that extends distally beyond a second channel to form an annular opening between the first channel and the second channel, the retinal manipulation fluid having a higher specific gravity than other fluids within the eye;
- applying negative pressure to the injection and extraction system to facilitate extraction of fluid from the eye through the annular opening;
- adjusting, via a computer system, the applied negative pressure;
- and
- extracting the other fluids from the eye.
