Maintenance of continuous infusion in the eye is an important consideration in many complicated intraocular surgeries.
Anterior segment surgeons mostly use an anterior chamber maintainer (ACM), and posterior segment surgeons commonly employ a trocar for the same. There are many advantages in employing a trocar cannula as an ACM too. The trocar anterior chamber maintainer (T-ACM) fits snugly into the eye and does not tend to leak or get extruded from the eye as an ACM often does in cases with a large side-port incision. This can lead to constant leakage and expulsion of the ACM from the eye and eventually leads to shallowing of the anterior chamber. The T-ACM overcomes this because the wound is a self-sealing port, and this eventually leads to better intraoperative control of IOP. The idea of employing a T-ACM was originally conceived by Dr. Amar Agarwal.
