Abstract:
AIM: To investigate the effect of wearing an orthokeratology lens on postoperative binocular vision rebuilding in patients with intermittent exotropia combined with myopic refractive error.METHODS: Prospective control study. A total of 60 patients(120 eyes)with intermittent exotropia and myopia who underwent surgical treatment in our hospital from June 2019 to December 2020 were selected. Patients who wore orthokeratology lenses or monofocal frame glasses after surgery were divided into a treatment group(group A)and a control group(group B)according to the wishes of patients and their families, with 30 cases(60 eyes)in each group, and they were followed-up for 6mo. The third level visual function and Titmus near stereoscopic visual function of the two groups of patients were observed before and 6mo after surgery.RESULTS: There was no statistical significance in all observation indicators between group A and group B before surgery(P>0.05). After 6mo of surgery, patients with intermittent exotropia achieved significant improvement in binocular visual function and corrected eye position. Group A was superior to group B in terms of fusion range and near stereoscopic visual function(P<0.05). There was no statistical significance between the two groups in terms of simultaneous vision and stereoscopic visual function(P>0.05).CONCLUSION: The binocular visual function of patients with intermittent exotropia after surgery has significantly improved. Wearing orthokeratology lenses can effectively improve binocular visual function in patients with intermittent exotropia combined with myopia after surgery.
