The paper presents the clinic's experience regarding the utilization of the Thread operation in strabismus surgery. This surgical technique was done on 27 patients with convergent strabismus for correcting the spastic component of the deviation angle. The post-operation results are promising; the control done one month after the intervention showed in all cases solving of the variable component of the strabismic deviation angle, orthophoria in 17 cases, remaining deviation angle under 5 grades in 8 cases, and above 5 grades in 2 cases.
