Effective treatment of the patients with postoperative corneal edema is one of the actual problems in ophthalmology. In this paper results of complex monitoring of influence of 40%-glucose solution on the state of both normal and edematous cornea after a cataract phacoemulsification on the base of date of confocal microscopy and optical coherence tomography have been presented. It has been shown that the glucose solution induces a short-term swelling of the healthy cornea and dehydration of the edematous one, as well as optical clearing of the tissue in the both cases.
