ABSTRACT:
A surge-flow regulator (36) for use with an ophthalmic surgical instrument (12) having an infusion line (20) adapted to irrigate a surgical site with fluid and an aspiration line (24) adapted to carry the fluid and particles of lenticular debris away from the surgical site. The surge-flow regulator (36) includes a flow limiting device (40) that is placed in fluid communication with the aspiration line (24) to control surge-flow of the aspirated fluid and lenticular debris through the aspiration line (24). The lenticular debris carried in the aspiration line (24) is processed into smaller particles before the fluid and debris are introduced to the flow limiting device (40).
