Summary

Long-term observation has shown that patients with visual impairment often develop cognitive impairments. Due to the fact that patients who are planning to undergo corneal transplantation may have initial cognitive deficits, assessing cognitive function is an important aspect of work for both the anesthesiologist and the operating surgeon. Given the high significance of assessing cognitive function after anesthesia in ophthalmic surgery patients, it is relevant to adapt and validate the Russian version of the MoCA Blind test for subsequent use in clinical practice.
