Flanged intraocular lens fixation via 27‐gauge trocars using a double‐needle technique decreases surgical wounds without losing its therapeutic effect

PURPOSE: Intraocular lens (IOL) fixation using a sutureless 27‐gauge needle intrascleral IOL implantation technique requires six surgical wounds. We developed a modified technique using two 27‐gauge trocars for vitrectomy and indwelling flanged IOL haptics to reduce the number of surgical wounds. SETTING: Department of Ophthalmology, Hyogo College of Medicine. DESIGN: This retrospective study enrolled 54 patients who had undergone IOL scleral fixation between January 2016 and April 2019. METHODS: Patients who underwent IOL scleral fixation and were observed for >12 weeks were analysed using medical record data. Before October 2017, patients underwent normal flanged IOL scleral fixation. Between November 2017 and April 2019, patients underwent the modified method (flanged IOL via 27‐gauge trocars with double‐needle technique). Primary end‐point was superiority or non‐inferiority of modified IOL scleral fixation compared with normal IOL scleral fixation for visual acuity (VA). Changes in corneal endothelium cell number, refractivity, astigmatisms and surgery‐related complications, were secondary end‐points. RESULTS: There were no significant differences in baseline characteristics between groups. Raw VA and best collected VA (BCVA) were significantly improved in all eyes (p−). There were no statistical significances in raw VA, BCVA and surgery‐related complications between groups. CONCLUSIONS: Results of the modified technique were not inferior compared with the original technique although it was less invasive. Therefore, flanged IOL fixation via trocars using a double‐needle technique is a useful technique for IOL implantation.
