AIM:To investigate the effect of GX-Ⅲ-type multi-functional ion therapeutic machine under microscope for the treatment of lacrimal point stenosis or occlusion.METHODS:Twenty-six patients (28 eyes) with puncta stenosis or occlusion underwent puncta plasty,and the treatment effectiveness was evaluated.RESULTS:One day after operation,the drainage of lacrimal ductule was unobstructed in 28 eyes. All patients were followed up for 3 to 6 months,and the recovery rate was 93%.CONCLUSION:Puncta plasty performed by GX-Ⅲ-type multifunctional ion therapeutic machine under microscope is an effective and simple therapy for the treatment of lacrimal point stenosis or occlusion,with less damage and pains.
