Efficacy of 25G vitrectomy combined with intrascleral intraocular lens implantation

We investigated the clinical efficacy and safety of 25-gauge (G) vitrectomy combined with intrascleral intraocular lens (IOL) implantation. A 25G vitrectomy combined with intrascleral IOL implantation was performed on 39 patients diagnosed with lens dislocation, IOL dislocation, or aphakia. Changes in visual acuity, intraocular pressure (IOP), number of corneal endothelial cells, location of IOL, anatomic success of IOL, recurrence rate of IOL dislocation, and complications were analyzed. One week postoperatively, the IOL was in the centered position in all patients (100%), and 1 month postoperatively, it was centered in 36 patients (92.3%). IOL haptics were exposed under the conjunctiva in one patient (2.6%). Reimplantation of IOL for IOL dislocation was required in two patients (5.1%). Three to six months postoperatively, the IOLs were in the optimum position in 36 patients (92.3%). There were significant differences between the average logarithm of minimal angle of resolution (logMAR) visual acuity at 1 week, 1 month, 3 months, and 6 months postoperatively and that before surgery (P < .05). The average IOP at 1 week, 1 month, 3 months, and 6 months postoperatively was significantly lower than the preoperative IOP (P < .05). A 25G vitrectomy combined with intrascleral IOL implantation is effective and safe for the treatment of eyes without capsular support.
