Appeal from an order of the Supreme Court, Erie County (John M. Curran, J.), entered August 25, 2014. The order denied the motion of defendants for summary judgment.

It is hereby ordered that the order so appealed from is unanimously affirmed without costs.

Memorandum: Plaintiffs commenced this medical malpractice action seeking damages for injuries allegedly sustained by Brenda Reading (plaintiff) when Andrew Fabiano, M.D. (defendant), a resident in neurosurgery at defendant Kaleida Health, doing business as Millard Fillmore Gates Hospital, applied a skin preparation solution to plaintiff during surgery to remove a pituitary tumor located near plaintiff's optic nerve. We reject defendants' contention that Supreme Court erred in denying their motion for summary judgment dismissing the complaint. Defendants failed to meet their initial burden of establishing the absence of any departure from good and accepted medical practice or that plaintiff was not injured by any such departure (see Sawyer v Health, 112 AD3d 1341, 1341 [2013]).

It is well established that a medical "resident who assists a doctor during a medical procedure, and who does not exercise any independent medical judgment, cannot be held liable for malpractice so long as the doctor's directions did not so greatly deviate from normal practice that the resident should be held liable for failing to intervene" (Wulbrecht v Jehle, 92 AD3d 1213, 1214 [2012] [internal quotation marks omitted]). Here, however, the affidavit of defendants' expert provided only conclusory assertions, i.e., assertions unsupported by any specific factual references, that defendant did not exercise any independent judgment (see Wulbrecht v Jehle, 89 AD3d 1470, 1471 [2011]). Furthermore, defendants submitted the deposition testimony of defendant, wherein he testified that he applied the solution based solely on what he believed to be a safe distance from plaintiff's eyes. Thus, defendants' own submissions raise an issue of fact whether defendant exercised independent judgment (see Sawyer, 112 AD3d at 1341). On the issue of proximate cause, defendants' expert improperly relied upon a disputed fact—specifically, that plaintiff's eye injuries were not caused by chemicals—in opining that defendants did not cause plaintiff's injuries (see Reiss v Sayegh, 123 AD3d 787, 789 [2014]). In view of our determination, we do not consider the sufficiency of plaintiffs' submissions in opposition to the motion (see Winegrad v New York Univ. Med. Ctr., 64 NY2d 851, 853 [1985]).
