Vitrectomy simultaneously combined with phacoemulsification for treating PDR / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To explore the effects of vitrectomy simultaneously combined with phacoemulsification on visual acuity, intraocular pressure(IOP), central macular thickness(CMT)and postoperative complications in patients with proliferative diabetic retinopathy(PDR).<p>METHODS:Totally 90 PDR patients(98 eyes)admitted to the hospital from February 2015 to February 2017 were divided into two groups according to the principle of voluntariness group A(vitectomy simultaneously combined with lensectomy, 45 cases, 50 eyes)and group B(vitrectomy simultaneously combined with phacoemulsification, 45 cases, 48 eyes). The follow-up period was 6mo. The visual acuity improvement, IOP before and after surgery, CMT and incidence of postoperative complications were compared between the two groups.<p>RESULTS: The visual acuity improvement after surgery in group B was significantly better than that in group A, and the improving rate of visual acuity was significantly higher than that in group A(<i>P</i><0.05). There was no significant difference in IOP before and after surgery between the two groups(<i>P</i>>0.05). The CMT after surgery was decreased significantly in both groups. CMT in both groups was not statistically different(<i>P</i>>0.05). The incidence rates of postoperative complication ssuch as INV, capsule turbidity, corneal edema, pupil hijacking and hard exudate in group B were significantly lower than those in group A(<i>P</i><0.05).<p>CONCLUSION:Vitrectomy simultaneously combined with phacoemulsification have obvious efficacy on PDR, which promote recovery of postoperative visual acuity, reduce CMT, and it has low risk of postoperative complications.
