Purpose:
To assess temperature on the eye surface after local anesthesia due to phacoemulsyfication.
Material And Methods:
15 patients treated with local anesthesia: peribulbar - 5, retrobulbar - 5 and sub Tenon anesthesia. Mean temperature on both eye surface was assessed with termovision camera (Inframetrics 760) before surgery, 20 minutes and 1 hour after anesthesia.
Results:
In all examined groups changes in temperature values in anesthetized and contralateral eye were observed. Significant decrease of temperature was observed after sub Tenon anesthesia.
Conclusions:
Eye surface temperature and its changes can be considered as indirect indicator of blood supply and blood supply disturbances after local anesthesia.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
