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.
