Claim:
1. A system for removal of vitreous humor and other fluids from an eye and reinjection of filtered vitreous humor into the eye, the system comprising: a hollow removal device including an element configured to cut the vitreous humor, the removal device configured to aspirate the vitreous humor from the eye; a vacuum source configured to power the aspiration of the vitreous humor from the eye into the removal device; an aspiration chamber, wherein the vacuum source is configured to power the aspiration of the vitreous humor from the eye into the aspiration chamber; a first fluid level sensor coupled to the aspiration chamber, wherein the first fluid level sensor is configured to measure a level of fluid within the aspiration chamber; a concentrator fluidly coupled to the aspiration chamber and configured to receive the fluid from the aspiration chamber when the first fluid level sensor detects a predetermined level of fluid in the aspiration chamber, wherein the concentrator is configured to create a concentrated form of the vitreous humor by separating the vitreous humor from the other fluids; a filter fluidly coupled to the concentrator, wherein the filter is configured to receive the concentrated form of the vitreous humor and create a filtered form of the vitreous humor by separating the vitreous humor from undesired components in the vitreous humor; a reservoir fluidly coupled to the filter and configured to receive the filtered form of the vitreous humor from the filter; a second fluid level sensor coupled to the reservoir, wherein the second fluid level sensor is configured to measure a level of fluid within the reservoir; an infusion device fluidly coupled to the reservoir and configured to return the filtered form of the vitreous humor into the eye when the second fluid level sensor measures a predetermined fluid level in the reservoir.
