Phaco Tip 142:
AC Too Deep

Rarely, the anterior chamber can be too deep for adequate visualization during phacoemulsification. This can occur in a myopic eye with thin, elastic sclera.

It can be dangerous to proceed with phaco when visualization is not adequate. The simplest way to overcome this problem is to inject a small amount (approximately .25 cc) of BSS^® Sterile Intraocular Irrigating Solution through the pars plana and into the central vitreous cavity. A disposable 30-gauge needle is best suited for this, and will create a self-sealing tract upon its removal.

N.B. Because the sclera can expand in these unusual eyes, the patient will often experience discomfort when the phaco tip is inserted and the choroid is stretched.
