The authors present a case series of patients who underwent this procedure and develop a surgical table to guide management.</p><p><strong>Methods: </strong>Patients with horizontal squints measuring 80 prism diopters (PD) or larger in all age groups who underwent extraocular muscle transplantation surgery between January 2019 and June 2022 in Nigeria were included. Preoperative deviation of the squint, sensory evaluation, surgical dosage, and outcomes were documented.
