Abstract
Recently, small incision cataract extraction by phaco and implantation of a foldable intraocular lense with topical anesthesia has used in an attempt to decrease the complication of general anesthesia and peribulbar injection. To compare effects and complications of topical, local and general anesthesia, 92 patients admitted to Imam Hosein hospital for cataract surgery, were randomly assigned to three groups and surgery was done under different methods of anesthesia. During routine ECCE, lid and globe movements, miosis and viterous bulg were observed more in topical anesthesia than the other techniques, but serious complications such as posterior capsular rupture and viterous loss were not seen. Because of less systemic and local complications and rapid return of vision and possibility of outpatient surgery, topical anesthesia should be considered as an alternative to local and general methods.

Abstract
Background: Phacoemulsification surgery is one of the most common surgeries in the world. Various drugs have been used alone or in combination with each other to provide effective and safe sedation in patients, but so far, a drug method agreed upon by anesthesiologists has not been proposed. The purpose of this research was to evaluate the sedative quality of midazolam or propofol with a low dose of ketamine in phacoemulsification surgery.
Methods: This study was a double-blind randomized clinical trial conducted from November 2017 to August 2019 at Faiz Hospital, Isfahan. In this study, 68 patients were assigned in the groups of midazolam (M) and propofol (P) using randomization software entered the study. The midazolam (M) group received 0.04 mg/kg and the propofol (P) group received 0.5 mg/kg, then in both groups, ketamine 0.3 mg/kg was injected intravenously. The quality of sedation, cardiovascular response and patient and surgeon satisfaction were assessed and recorded. Data were entered into SPSS 23 software and analyzed by using ANOVA and Independent samples t‐test.

Results: In this study, between the two groups in terms of demographic characteristics there was no significant difference (P>0.05). In the KM group, higher percentage of patients achieved the desired quality of sedation, but, between the two groups no statistically significant difference was shown (P=0.75). Surgeon satisfaction was higher in the KP group (P=0.18) and patient satisfaction was higher in the KM group (P=0.18) but there was no significant difference (P>0.05). Recovery time between groups was Similar and no statistically significant difference was shown (P>0.98). In the KM group at 5 minutes, systolic blood pressure (SBP) was notably greater than the other group (P=0.02) and diastolic blood pressure was notably greater than the KP group (P=0.08).
Conclusion: It can be stated that adding a small dose of ketamine to propofol and midazolam is associated with effective sedation and a similar cardiovascular response during phacoemulsification surgery.

Abstract
Background: The risk of anesthesia increases with age, so it is necessary to choose a safe and effective method. In this study, we compared the effectiveness of intranasal fentanyl with intravenous fentanyl in patients undergoing cataract surgery.
Methods: This study was a triple-blind prospective randomized clinical trial (The patient, physician, and data analyzer were unaware of the patient grouping). The study was performed from April 2017 to March 2019 in Feyz Hospital, Isfahan, Iran. 90 patients over 18 years of age who were candidates for cataract surgery were included in the study and were divided in two groups receiving intravenous fentanyl (IVF) or intranasal fentanyl (INF). The dose of fentanyl in both groups was 1.5 μg/kg with a maximum of 100 μg. In the IVF group, 1 ml of normal saline was dripped into each nasal passage 10 minutes before surgery and intravenously fentanyl was injected 2 minutes before surgery. In the INF group, 1 ml of fentanyl was administered into each nostril 10 minutes before surgery and 2 ml of saline was administered intravenously two minutes before surgery.

Results: In this study, there was no significant difference between the two groups in terms of mean heart rate (P=0.762), mean arterial blood oxygen saturation (P=0.262), mean systolic blood pressure (P=0.264), mean arterial blood pressure (0.462), satisfaction rate Patient (P=0.231), duration of surgery (P=0.612) and pain intensity (P=0.87). But in the intravenous fentanyl group (IVF), the level of sedation (P=0.002) and the level of surgeon satisfaction (P<0.001) were higher than intranasal fentanyl group (INF). There was no significant difference between the two groups in terms of side effects (P=0.171) and surgery time (P=0.612). The mean VAS was not significantly different between the two groups.
Conclusion: The study showed that intranasal administration of fentanyl compared with intravenous administration of fentanyl provided similar sedation and cardiovascular response. Intranasal administration of fentanyl is a non-invasive, safe and effective method, that is easy to use and can be a viable alternative to intravenous administration.
