One-stage Adjustable Strabismus Surgery Under AIVOC

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to note that one-stage adjustable surgery can be enough to provide satisfactory results for the correction of strabismus in adults thanks to the use of an anesthesia type AIVOC (Target-controlled infusion of Propofol-Remifentanyl)

Detailed Description
-----------------
Adjustable surgery is a surgical treatment technique for strabismus and oculomotor paralysis well known and widely used around the world. The adjustable surgery is done in 2 steps. The first step, performed under general anesthesia, is practically the same as classic strabismus surgery however one or more muscles are fixed by temporary sutures. In a second time once the patient is awake and after a new clinical examination the sutures are adjusted and definitively fixed. The adjustment is sometimes made the same day but more often the day after the first intervention because it requires a state of consciousness close to normal. Anesthesia type Intravenous Intensity Concentration Anesthesia (AIVOC) allows the realization of a surgery under anesthesia general deep (choice of a cerebral or plasma anesthetic target suitable for surgery) but allows a programmed awakening, very fast in full consciousness, condition of an immediate reliable adjustment practically upon stopping the infusion of the anesthetic agent. The goal is to present an adjustable surgery technique simplified from a logistical point of view since performed in a single step thanks to the contribution of Intravenous Anesthesia with Concentration Objective (AIVOC) and to show that its results are equivalent to a second deferred time.
