Abstract

Purpose : To compare the outcomes of 20, 23, 25 gauge(G) pars plana vitrectomy (PPV) for lens fragment dropped into vitreous cavity during cataract surgery.

Methods : This was a comparative, retrospective, interventional case series study, the medical chart were reviewed. One-hundred seventeen eyes of 117 patients with dropped lens fragments into the vitreous underwent PPV from March 1, 2010 to July 31, 2017. Thirty-one, 52, and 34 eyes underwent 20G PPV, 23G PPV, 25G PPV, repsectively. The analysis included charaacteristics of the patients, visual acuity, opertion times, and rate of complications.

Results : The mean interval between Preoperative characteristics were similar in the 3 groups. The mean interval between cataract surgery and PPV was 0.58±1.1 days, and all of PPV were performed within 4 days after cataract surgery. The mean best-corrected visual acuity(logMAR) improved from 1.42 ± 0.78 to 0.21±0.15 (p = 0.00), from 1.34 ± 0.87 to 0.43±0.62 (p = 0.013) and from 1.91 ± 0.59 to 0.42 ± 0.51(p = 0.00) with 20, 23, and 25-G systems, respectively. The size of the lens and mean operation time were found to have a positive correlation(R2 = 0.86, P<0.01). Modified PFCL technique(lens fragments floated to the iris plane and was removed using phacoemulsification) was used in twenty eyes(12 cases: 23G group, 8 cases: 25G group). The time of operation was significantly lower in the 23G and 25G group than in the 20G group (P = 0.03). There were no cases of post-operative hypotony or endophthalmitis seen. Retinal detachment developed in 2 patients (6.4%), occurring only in patients of 20G group.

Conclusions : It is considered that 23G and 25G MIVS for lens fragments dropped into the vitreous cavity during cataract surgery can be a safe and effective way for dropped lens fragments of modest size.
