Background:

Despite international efforts to conduct a standardized surgical safety protocol, there are still errors such as operating on the wrong eye. There is a universal protocol that was implemented back in July 2004 by the joint commission that seeks to prevent errors. It includes three basic points: preoperative verification, marking of the surgical site and immediate waiting time before the incision.

Objective:

To propose a marking method that allows us, in addition to knowing which eye to operate on, to have both a horizontal and vertical surgical approach, on the patient's skin to have more certainty the procedure to be performed.

Method:

Description of the marking technique in patients with strabismus based on the type of deviation, and surgery proposed in each muscle and patient.

Results:

Several examples of the surgical plan are presented with photos and diagrams.
