Protocol summary

Summary
Our general objective in this study is assessing intraocular pressure (IOP) changes after intubation with three types of laryngoscope (McCoy, Macintosh and video laryngoscope or Glidescope). This is a double blind and prospective clinical trial on 180 patients subjected to cataract surgery in Shafa Hospital. Inclusion criteria are: patients who are admitted for elective cataract surgery, age: 20-70 year and have ASA classification as 1 or 2. Exclusion criteria are: history of alcohol and drug abuse, antihypertensive and cardiovascular medicines usage, glaucoma eye drop usage, diabetes and open eye injuries. The patients will be divided into three groups. Induction of anesthesia in all patients is similar. Just after induction and before intubation, intraocular pressure (IOP) will be measured by means of Schiotz tonometer. Then intubation will be done by Mccoy laryngoscope in group A, Macintosh laryngoscope in group B and glidescope in group C. After intubation IOP is measured again and anesthesia is maintained on Isoflurane. IOP is measured again five minutes later. Collected data will be analyzed by Repeated Measures ANOVA test.

Other design features
All patients will sign informed consent and they will be divided into three groups by means of random numbers table. Intubation is done by an anesthesiologist and the resident of anesthesiology who is blind to the kind of laryngoscope will obtain IOP, heart rate and blood pressure. Moreover the patients are unaware of the kind of used laryngoscope.
