Abstract:
Objective To investigate factors that affect the treatment effect of laser vitrectomy for vit-reous opacity and the related factors that affect patient satisfaction,so as to evaluate its clinical value.Methods A total of 196 patients with vitreous opacity treated using the Ultra Q ReflexTM Nd:YAG laser system at our hospital between October 2019 and February 2024 were enrolled.Patient medical records and satisfaction questionnaires were analyzed.Investigational data underwent machine-coded classification,and a Python-based decision tree prediction model was employed to identify factors affecting treatment outcomes.Stata18.0 OLS linear regression was used to assess correlations between patient satisfaction and variables such as healthcare provider quality,treatment accessibility,and medical environment.Results After laser vitrectomy,95.3%of patients with vitreous opacity showed significant improvement in symptoms,and 90.3%expressed satisfac-tion with the improvement in postoperative visual quality.Patients'gender,age,preoperative vitreous opacity morphology,and refractive error below-6.00D had an impact on the treatment outcome(P<0.05).Python decision tree analysis demonstrated superior efficacy in patients aged>30-45 years with 6-12 months of symptom duration and refractive error<-6.00D.Stata18.0 OLS linear regression analysis showed that all examined variables were positively correlated at the 1%significance level,with patients'expected feelings having the greatest impact on postoperative satisfaction with treatment(r=1.053).Conclusion Ultra Q Nd:YAG laser vitreous ablation demonstrates high safety and patient satisfaction for vitreous opacity treatment.
