Simple technique for sealing clear corneal wound leaks using a dynamic anterior chamber air bubble.

摘要

Wound leak has been demonstrated in 31% of clear corneal incisions (CCIs) at the conclusion of phaco-emulsification surgery. We describe a technique for effectively sealing a clear corneal wound with subsequent confirmation of a watertight seal. Clear corneal phacoemulsification is performed under topical anesthesia, and surgical ports are hydrated. If the wound is leaky, an air bubble is injected into the anterior chamber through the side port so the bubble's diameter is one third to one half the corneal diameter. The side port is rehydrated.
