The Efficacy Of Varying Degrees Of Angle Closure By Lensectomy

Objective：To observe the effect of lensectomy on the patients withvarying degrees of angle closure and to provide clinical guidance for glaucomawith cataract surgery.Methods：39cases (45eyes) with varying degrees of angle closure andcataract were chosen and divided into three groups according to different statesof angle closure：A：9cases (12eyes), narrow angle with limited adhesionwithout defect of visual field and angle adhesion closed≤180°. B：19cases (22eyes), angle closure with defect of visual field,180°＜angle adhesion closed≤270°. C：11cases (11eyes), continuing status primary angle closure, unseencontinuing status. Phacoemulsification with PC-IOL implantation andgoniosynechialysis were performed on patients from three groups. All patientswere follow-up for one to three months. The postoperative visual acuity,intraocular pressure, anterior chamber depth, angle and complications wereanalyzed.Results：Group A: the preoperative average intraocular pressure was21.28±6.23mmHg, while average intraocular pressure was19.0±2.83mmHgadhesion of angle was reopened after surgery. Anterior chamber depth was2.46±0.4mm before surgery and changed to3.54±0.43mm after surgery. Group B:the preoperative average intraocular pressure was21.22±7.52mmHg, while average intraocular pressure was16.0±3.80mmHg and adhesion of angle wasangle adhesion closed≤180°after surgery. Anterior chamber depth was2.01±0.44mm before surgery and changed to3.21±0.48mm after surgery. Group C:the preoperative average intraocular pressure was41.27±11.82mmHg, whileaverage intraocular pressure was16.96±5.32mmHg and adhesion of anglewas re-openedafter surgery. Anterior chamber depth was2.46±0.4mm beforesurgeryand chagned to2.46±0.4mm after surgery. All patients had deeperanterior chamber depth and enhanced visual acuity after surgery.Conclusions:1. To the patients with varying degrees of angle closure，adhesion of angle were re-opened after Phacoemulsification with PC-IOLimplantation and goniosynechialysis.2. To the paients with primary closedangle glaucoma with cataract, Phacoemulsification with PC-IOL implantationand goniosynechialysis was one of treatments to be chosen, which was able tocontrol intraocular pressure effeciently, re-open anterior chamber angle anddeepen the anterior chamber after surgery.
