Efficacy of ultrasound phacoemulsification cataract extraction in combination with IZHV on malignant glaucoma
Objective To evaluate the efficacy and safety of ultrasound phacoemulsification cataract extraction+intraocular lens implantation+irido-zonulo-hyaloid-vitrectomy(IZHV)procedure via corneal incisional approach in treating malignant glaucoma.Methods Ten patients(10 eyes)were diagnosed with malignant glaucoma in Henan Provincial People's Hospital from August 2022 to August 2023.After routine ultrasound phacoemulsification cataract extraction and intraocular lens implantation,IZHV was performed via corneal incisional approach.One week after surgery,the naked visual acuity,intraocular pressure,and anterior chamber depth were measured for efficacy evaluation.The occurrences of complications such as intraocular lens displacement,choroidal detachment,intraocular pressure elevation and shallow anterior chamber were recorded.Results One week after surgery,the visual acuity was improved in 10 patients(≥0.3 in 6 patients and＜0.3 in 4).The intraocular pressure ranged from 8.2 to 16.5 mmHg,and the anterior chamber returned to normal.All patients achieved recovery without complications such as intraocular lens displacement,choroidal detachment,intraocular pressure elevation,or shallow anterior chamber.Conclusion The surgery of ultrasound phacoemulsification cataract extraction+intraocular lens implantation+IZHV via corneal incisional approach is safe and effective for patients with malignant glaucoma.
