Abstract
Objective To evaluate the effect of ultrasound biomicroscopy (UBM) on diagnosis and treatment of traumatic lens subluxation.Methods 35 patients (35 eyes) suffered with lens subluxation were studied in the past 3 years.All the patients underwent UBM examination.The degree and extent of lens luxation was measured to determine the operation procedure.The operation methods included phacoemulsification and intraocular lens implantation ( Phaco + IOL),phacoemulsification and intraocular lens implantation with tension ring implantation ( Phaco + IOL + TR),trabeculectomy and anterior vitrectomy,which was choosed depending on the traumatic starus.Results UBM examination is valuable for the early diagnosis of lens subluxation.According to lens subluxation and complications,we apply different surgical methods,postoperative visual acuity were improved.Conclusion UBM can help early diagnosis of subluxation of lens; UBM is a powerful means on surgical method and the timing of operation in lens subluxation.
