Kahook双刃刀内路小梁切除术的应用进展

Progress in application of KDB ab-interno trabeculectomy on glaucoma treatment

Kahook双刃刀(Kahook dual blade,KDB)内路小梁切除术作为微创青光眼手术中的一种,可在较大范围内对小梁网进行切除,且不破坏临近组织,降低房水排出阻力,进而降低眼压,对多种类型青光眼有一定的治疗效果。与滤过泡依赖手术比较,其操作简便,手术并发症少,安全性高,不破坏结膜,不影响后续手术。本文对KDB内路小梁切除术治疗青光眼的原理、手术步骤、有效性、安全性、联合手术等进行综述。

As one of the minimally invasive glaucoma surgeries,KDB Abinterno trabeculectomy can remove trabecular meshwork in a wide range without destroying adjacent tissues,reducing the resistance of aqueous outflow,and thus reducing intraocular pressure.It has certain therapeutic effects on a variety of types of glaucoma.Compared with filtration bleb dependent surgery,it is simple,less complications,high safety,does not destroy the conjunctiva,and does not affect the subsequent operation.This article reviews the principle,procedure,efficacy,safety and combined operation of KDB ab-interno trabeculectomy for glaucoma.
