Effect of Phacoemulsification After A Small Number of Central Vitrectomy in Patients with Vitreous Accumulation Cataract
Objective To investigate the efficacy and safety of a small central vitrectomy prior to cataract surgery in eyes without red light reflection due to vitreous hemorrhage.Methods Retrospectively analysis.From January 2022 to April 2024,40 patients(40 eyes)with vitreous cataract admitted to the First Eye Department of the First Affiliated Hospital of Zhengzhou University had unclear red light reflex in the fundus.They were divided into two groups:group A(20 eyes)and group B(20 eyes).Patients in group A underwent phacoemulsification combined with intraocular lens implantation first,and then underwent total vitrectomy.Group B underwent a small amount of central vitrectomy(0.5-1 mL),followed by cataract phacoemulsification combined with intraocular lens implantation,and finally complete vitrectomy.Postoperative follow-up was not less than 6 months.All patients underwent 23G phacoemulsification combined with vitrectomy.The operative time(total time of continuous annular capsulorhexis,total time of cataract operation)and the incidence of surgery-related complications were observed.Results The total time of continuous curvilinear capsulorhexis and cataract operation in group B were shorter than those in group A(P＜0.05).In the complications,the incidence of anterior capsule tear in group A was higher than that in group B(P=0.072).During cataract surgery,Pupil size reduction during cataract surgery in group B was greater than that in group A(P=0.152).No posterior capsule rupture occurred in both groups.The best corrected visual acuity of group A and group B after surgery was significantly higher than that before surgery,and the difference was statistically significant(P＜0.05).Conclusion A small amount of central vitrectomy(0.5-1.0 mL)is performed before phacoemulsification cataract surgery in patients with vitreous hemorrhage,which helps to obtain a good red light reflex and reduces cataract surgery time and complications associated with cataract surgery.
