The assessment of refractive outcome in patients who underwent pars plana vitrectomy and intraocular lens implantation in the same session due to lens or lens fragments drop

PURPOSE: The objective is to reveal the results of patients who underwent pars plana vitrectomy (PPV) in the same session due to lens nucleus drop during cataract extraction and to compare the refractive results according to uncomplicated pha-coemulsification (phaco) surgery.
METHODS: The study included 26 eyes of 26 patients who underwent PPV due to lens or lens fragments drop. Preoperative and postoperative best-corrected visual acuity (BCVA), intraocular pressure, spherical equivalent, and the intraocular lens (IOL) implantation methods applied were recorded. Refractive results were compared with the spherical equivalent of 24 eyes of 19 patients who underwent uncomplicated phaco surgery.
RESULTS: Three-piece IOL was implanted in the ciliary sulcus in 20 (77%) patients, and IOL was implanted in one (4%) patient with sutureless scleral fixation using the Yamane technique. In 5 (19%) cases, the surgeries were terminated as aphakic. Preoperative BCVA was 1.3±0.5 logMAR, and postoperative BCVA was 0.29±0.4 logMAR (P<0.001 for both subgroups). Preop-erative spherical equivalent was −4±2 D, and it was −0.8±1.4 D after the operation (P<0.001). In patients with PPV and IOL implantation, the postoperative spherical equivalent was −0.8±1.4 D, and it was measured as −0.7±0.6 D in the phaco-only group (P=0.37).
CONCLUSION: It is possible to achieve optimal results in uncomplicated phaco surgery using IOL measurements calculated with appropriate biometric formulas and advanced optical biometry devices in patients who have undergone PPV due to lens nucleus drop. IOL implantation can be easily planned in the same session for patients undergoing PPV.
