Maintenance of the Anterior Chamber Depth During Anterior Segment Surgery

Arch Ophthalmol. 1967;77(3):384-386. doi:10.1001/archopht.1967.00980020386017

MAINTENANCE and control of the anterior chamber depth during surgery of the anterior segment are of importance in certain ophthalmic procedures. New techniques to achieve this goal have been developed but their use has not always prevented loss of the chamber leading to failure or only partial success of the intended surgery. In addition, many of these techniques have proved to be cumbersome, complex, or ineffectual.1-6

Continuous control of the anterior chamber depth can be easily attained by use of a method to be described. The technique can be used in any surgical procedure in which maintenance of the anterior chamber is desired and it has the added advantage of being simple.
