Intraocular tamponade use in pars plana vitrectomy combined with sutureless intrascleral lens implantation

Purpose: To evaluate the effect of intraocular tamponade use on anatomic and functional results and complications in pars plana vitrectomy (PPV) performed simultaneously with sutureless intrascleral lens implantation. Methods: Patients were divided into two groups according to the type of tamponade used in surgery. Group-1 included patients who underwent 23G PPV with simultaneous 27G needle-assisted sutureless three-piece intrascleral lens implantation and intraocular silicone tamponade. Group-2 included patients who underwent 23G PPV with simultaneous 27G needle-assisted sutureless three-piece intrascleral lens implantation and intraocular C3F8 tamponade. Best corrected visual acuities (BCVA), centralization and stabilization of the intraocular lens, and complications were compared between the two groups. Results: 15 eyes of 15 patients were included in Group-1, and 14 eyes of 14 patients in Group-2. Preoperative BCVA of Group-1 was 1.82 logMAR, and signifi cantly increased to 0.71 logMAR at the 6th month (p = 0.022). Preoperative BCVA of Group-2 was 1.92 logMAR, and signifi cantly increased to 0.67 logMAR at the 6th month (p = 0.029). There was no signifi cant difference between the visual acuities of both groups at 6 months (p = 0.09). At sixth month, intraocular lens in both groups was centralized and stabilized in biomicroscopic examination and cycloplegic refraction. The most common early complication was increased intraocular pressure, and developed in 4 (26.6%) patients in Group-1 and 3 (21.4%) patients in Group-2. Conclusion: 23G PPV with silicone or C3F8 tamponade can be performed simultaneously with 27G needle-assisted sutureless intrascleral lens implantation.
