Abstract

COLLAPSE OF ANTERIOR CHAMBER SPACE DURING SURGERY CAN POTENTIALLY RESULT IN ENDOTHELIAL CELL DAMAGE BY INADVERTENT MECHANICAL TRAUMA BY SURGICAL INSTRUMENTS OR IRIS TISSUE DAMAGE WITH SECONDARY BLEEDING INTO CHAMBER
ACMAINTAINER IS AN INFUSION CANNULA WHICH IS INSERTED VIA THE CORNEA IN ORDER TO CREATE A STRONG INFLOW OF BALANCED SALT SOLUTION. INFUSION PREVENTS ANTERIOR CHAMBER PRESSURE FROM FALLING AND THUS THERE IS MINIMAL OR NO VITREOUS PROLAPSE.
IN A CASE OF ENDOPHTHALMITIS IN THE PRESENCE OF EXUDATES, AC MAINTAINER TIP VISIBILITY IS GOOD IN COMPARISON TO THE POSTERIOR CHAMBER INFUSION PORT. ALSO, THE SUPRACHPROIDAL VIEW IS NOT HAMPERED AS THE AC MAINTAINER TIP IS VIEWED BETTER.
USES- ANTERIOR VITRECTOMY ,IOL-RELATED PROCEDURES,CORNEAL PROCEDURES;IT CAN ALSO REPLACE USE FOR VISCOELASTIC
ALTERNATIVE IS THE USE OF VISCOELASTIC SUBSTANCES BUT DRAWBACK ASSOCIATED WITH IT IS ELEVATED IOP DUE TO DECREASED AQUEOUS OUTFLOW DUE TO BLOCKAGE OF THE TRABECULAR MESHWORK
