Analysis of minimally invasive vitrectomy combined with lens replacement for myopic foveoschisis in young and middle-aged / 实用医学杂志

ABSTRACT

Objective To investigate the clinical effects of minimally invasive vitrectomy combined with cataract surgery for myopic foveoschisis in young and middle-aged. Methods Sixty myopic eyes with myopic fo-veoschisis diagnosed from September 2013 to October 2015 in our hospital were included in the study. According to different surgical methods ,patients were divided into two groupscombined operation group(vitrectomy combined with lens replacement surgery,30 eyes)and staged operation group(simple vitrectomy group,30 eyes). Cataract surgery were performed according to the opacity of lens. All the patients were followed up for 6~12 months. Reop-eration rate of staged operation group ,the best corrected visual acuity(BCVA),the distant and near visual acuity and retinal reattachment rate of each group were observed. Every patient was interviewed with a questionnaire about visual quality at 6th month after surgery. Results 27 eyes developed lens opacity after operation(90%)in staged operation group,among them,21 eyes underwent secondary cataract surgery(70%). The BCVA recovery,postop-erative distant vision,and preoperative and postoperative distant vision difference in the combined operation group were significantly higher than those in the staged group(P<0.05). There were no significant differences in macu-lar retinal condition and retinal reattachment rate between the two groups(P > 0.05). Six months after operation, the visual quality of the combined operation group was significantly better than that of the staged group(t=-3.95, P = 0.00). In the combined surgery group,the scores of distant vision,stereopsis and visual fatigue were higher than those of staged operation group. The score of dry eye and night glare in staged operation group was higher than that in combined operation group(all P<0.05). Conclusions Vitrectomy combined with intraocular lens replace-ment for myopic foveoschisis in young and middle-aged people can avoid second operations and improves the visual function,proving to be a feasible operation in clinic.
