Introduction:Post-Operative Cognitive Disorder (POCD)in surgeries under general anesthesia is a relatively
common event and its diagnosis after surgery is particularly important in the elderly. In this study, the
frequency of cognitive disorders after cataract surgery with different anesthetic methods in the elderly was
evaluated to identify the effective factors and identifying the appropriate method with the lowest incidence of
cognitive impairment.
Materials & Methods:In a cross-sectional study, 108 patients over 60 years of age who were referred to
Semnan hospitals for elective cataract surgery were randomly assigned into three groups of anesthetics (local,
inhalation, and intravenous) and the Mini-Mental State Examination (MMSE) was done for cognitive assessment
in three steps: before surgery, three and seven days after the operation.
Results: The groups were matched based onage and gender. Patients had no difference in preoperative
cognitive test. In cognitive test on the third and seventh day after surgery, in order to assess the cognitive
effects of anesthetic drugs, there was a significant difference between different anesthetic methods, which was
higher on the seventh day. Among the three different methods of anesthesia (inhalation, intravenous, local)
that were used in cataract operation, the least cognitive impairment was observed in patients with local and
the most cognitive impairment was in patients with inhalation anesthetics.
Conclusion: The use of local anesthesia for cataract surgery has the lowest postoperative complications
compared to other general anesthetic procedures, and it is recommended to use this method if not
contraindicated.
