摘要

AIM: To compare the clinical outcomes of combined25-gauge pars plana vitrectomy（PPV） and phacoemulsification/posterior chamber intraocular lens（PC-IOL） implantation with vitrectomy alone surgery in patients with various vitreoretinal diseases.METHODS: A total of 306 eyes（145 with PPV alone and 161 with phaco-vitrectomy） were enrolled in this retrospective analysis. The surgical approach was 25-gauge PPV combined with phacoemulsification and PC-IOL implantation at the same time in eyes in phaco-vitrectomy group and only PPV in eyes in vitrectomy alone surgery group. The main outcome measures were postoperative clinical outcomes included anterior chamber inflammation, changes in intraocular pressure（IOP） and best corrected visual acuity（BCVA）.RESULTS: The most common postoperative complication was anterior chamber reaction which has higher incidence in phaco-vitrectomy group（P <0.001）.The mean postoperative 1st day IOP of vitrectomy alone group was significantly lower than that of phaco-vitrectomy group（16.3 ±5.8 mm Hg vs 17.8 ±8.1 mm Hg,respectively, P =0.02）. Hypotony(IOP（8 mm Hg） was not different between groups in the postoperative 1st day（P >0.05）. The mean preoperative visual acuity was not different between groups（1.6±0.9 log MAR vs 1.8±0.9 log MAR,respectively, P >0.05）. However, the mean visual acuity was decreased in vitrectomy alone group at the final visit compared to phaco-vitrectomy group（1.2 ±0.8 log MAR,0.9±0.7 log MAR, respectively P <0.05）.CONCLUSION: Twenty-five gauge PPV combined with phacoemulsification surgery is a safe and efficient procedure, which can be preferred in phacic patients with a variety of vitreoretinal diseases compared to vitrectomy alone. Despite improved outcomes, this approach is not free of limitations as anterior chamber complications especially with combined surgery.
