Significant Preoperative Anxiety Associated with Perceived Risk and Gender in Cataract Surgery

Abstract

Background/Objectives: Cataract surgery is an often-sought solution to the universal problem of lens opacification. Studies of perioperative anxiety have yielded conflicting results, reporting a high prevalence but low clinical significance. The objective of this study was to ascertain anxiety levels immediately after the scheduling of surgery, controlling for trait anxiety and other related factors. Methods: This is an observational comparative study of two patient populations assessed for receiving cataract surgery, with one group of seventy patients scheduled for operation and receiving an assessment of the potential perioperative risk and the other group of seventy patients deemed ineligible for operation since their opacification was not advanced. The patients were assessed for state and trait anxiety while controlling for cognitive status. Results: The findings indicate a clinically significant burden of state anxiety in the group of patients scheduled for operation, with 34 out of 70 meeting the threshold for clinically significant levels of state anxiety compared to 9 out of the 70 patients who were not assigned for surgery (p < 0.001). Those patients who were assigned for surgery were assessed for perioperative risk factors, and state anxiety differed statistically significantly between the preoperative risk factor groups, (p = 0.003) with those assessed as having at least low perioperative risk presenting with more anxiety than those without any risk factors. Male patients exhibited lower state anxiety compared to female patients in the group assigned to surgery (p = 0.028). Cognitive status did not affect the results. Conclusions: These findings point to the importance of prevention against perioperative anxiety early on, especially in patients with a higher perioperative risk and female gender.
