Introduction: To explore the clinical efficacy of intrascleral suture fixation of intraocular lens (IOL) combined with vitrectomy and phacoemulsification in the treatment of complete luxation of lens. 

Materials and methods: A total of 45 patients (45 eyes) with complete luxation of lens treated in our hospital from January 2019 to January 2022 were retrospectively included. All patients were treated by intrascleral suture fixation of intraocular lens combined with vitrectomy and phacoemulsification. The uncorrected visual acuity, best corrected visual acuity, corneal endothelial cell count, central corneal thickness and safety indicators before and after surgery were analyzed. 

Results: The uncorrected visual acuity and best corrected visual acuity of patients at 6 months after surgery were significantly higher than those before surgery (P<0.05). There were no significant differences in corneal endothelial cell count and central corneal thickness before and after surgery (P>0.05). No complications were observed during surgery and no IOL decentration, tilt or vitreoretinal complications occurred during the 6-month follow-up. 

Conclusion: Intrascleral suture fixation of intraocular lens combined with vitrectomy and phacoemulsification is safe and effective in the treatment of complete luxation of lens, and of clinical application value.
