Comparison of Fentanyl and Propofol versus Alfentanil and Propofol to limit Patient ́s EYEMovements during Cataract Surgery under

Eye movements during opht-halmic surgery cause irreparable complic-ations. So the aim of this study was to com-pare the combined use of fentanyl and pr-opofol versus alfentanil and propofol to limit patient´s eye movement during cataract surgery under topical anesthesia. In this double-blind clinical trial study, patients were randomly divided into two groups. The first Group received Fentanyl 1 µg/kg, and the second one received Alfentanyl 10 µg/kg. Then local anesthesia was done with Tetracaine drops, and cataract surgery was performed by the Phacoemulsification technique. Blood pres-sure and heart rate were measured at the time of injection of anesthesia, and minutes 10 and 30. The rate of eye movement was recorded by an observer surgeon who didn´t know anything about grouping. 246 patients were evaluated. There was no significant difference between blood pressure and heart rate at minutes 10 and 30. Movement of patients´s eye at minutes 10 (Chi-square=0.000001) and 30 (Chi-squ-are=0.000118) was significantly lower in Alfentanyl group than the other one. Discussion & The results of our study showed that Alfentanyl, in comparison with Fentanyl, causes more analgesia, less movments of the patient´s eye, and higher amount of surgeon´s satisfaction.
