“…Their study demonstrated that total LOA and astigmatism increased 3 days after horizontal rectus muscle surgery in patients with bilateral lateral rectus recession, unilateral lateral rectus recession, and medial rectus resection. [ 15 ] A similar outcome was observed in a study carried out by Preslan et al . [ 7 ]…”

“…The majority of studies concentrated on the refraction and corneal topography after strabismus surgery reported a transient change in stigmatism and corneal curvature. [ 12 13 14 15 ] The present study assessed aberrometry changes following strabismus surgery in patients with horizontal strabismus. Although no decrease was observed in VA, there was a transient increase (1 month postoperative) in aberrometry and irregularity index in corneal tomography.…”

“…HOAs include third-, fourth-, and HOAs, such as coma, trefoil, and spherical aberration, which cannot be corrected by any reliable means of the present technology. [ 15 ] Based on the literature, a significant astigmatic axis shift toward with-the-rule astigmatism has been the most important change after horizontal strabismus surgery. [ 12 , 16 17 18 ] Corneal curvature alteration is the possible cause of increasing horizontal astigmatism.…”

“…Deformity of the cornea on the force line is due to the changes in the pulling force of the extraocular muscles on the sclera, which leads to changes in corneal astigmatism. [ 15 ] These changes are shown to be temporary and they return to the primary status 7–60 days after the surgery. [ 12 , 17 18 19 ]…”

BACKGROUND: The aim is to investigate the change in aberrations following strabismus surgery in patients with horizontal strabismus. MATERIALS AND METHODS: This prospective study included patients who underwent surgery for horizontal strabismus. The patients were assessed preoperatively and 1 month and 3 months after the surgery, in terms of logMAR best-corrected visual acuity, eye deviation, spherical equivalent refractive error, tomographic and aberrometric corneal changes. Corneal tomography was performed using Orbscan II device. Wavefront analyses were performed using Bausch and Lomb Zywave II. RESULTS: A total of 25 patients (48 eyes) with exotropia or esotropia were entered in this study. Mean values of exotropia in the distance and near deviations were reported as 31.42 ± 7.13 and 28.82 ± 6.96 prism diopters (PD), respectively. Mean scores of esotropia in the distance and near deviations were 25.22 ± 5.41 and 30.45 ± 9.4 PD, respectively. Evaluation of irregularity in 5 mm zone, horizontal coma, spherical aberration changes, and root mean square of higher-order aberrations (HOAs) in 6 mm, and HOA w/o Z 400 changes showed that there was a significant difference before the intervention and 1 month after the surgery ( P < 0.05). However, no difference was observed in the aforementioned variables before and 3 months after the intervention ( P > 0.05). CONCLUSIONS: Results of the present study indicated a transient increase in HOAs and corneal irregularity following strabismus surgery on horizontal eye muscles that returned to the baseline after 3 months.

“…A large number of studies have shown that the formation of stereo vision requires not only the coordination of both eyes, but also the fine and complex processing of cerebral cortex, in which visual perception plays an important role [22][23] . In addition, the visual perception function of brain nervous system is plastic [24] .…”

AIM: To explore the effect of visual perception learning software training (VPT) on binocular visual function reconstruction in children with intermittent exotropia after strabismus surgery. METHODS: Ninety children with intermittent exotropia admitted to our hospital from June 2018 to December 2018 were included, and randomly divided into VPT and control groups. Children in the control group received basic binocular vision training, while those in the VPT group received VPT after strabismus surgery. Tertiary visual function, visual perception function, Newcastle Control Score (NCS), and ocular position retraction rate were compared at 3 and 12mo after the surgery. RESULTS: At 3 and 12mo after the surgery, the proportion of simultaneous perception, binocular fusion version and binocular stereo vision in the VPT group was conspicuously higher than that in the control group (P<0.05). After the vision training, the binocular visual perception functions of children in both groups were significantly improved compared with that before training (P<0.05). Interestingly, the grating sharpness, texture perception and texture motion perception in the VPT group were dramatically better than control group (P<0.01). The NCS in the VPT group was significantly lower than that in the control group (P<0.05). The ocular position retraction rate in the VPT group was significantly lower than that in the control group at 12mo (8.89% vs 26.67%, P=0.03). CONCLUSION: VPT effectively promotes binocular visual function reconstruction in intermittent exotropia children after strabismus surgery and reduces the strabismus severity and ocular position retraction rate.
