We describe a surgical technique combining penetrating keratoplasty and cataract surgery with a secure anterior chamber to manage coexisting corneal opacity and cataract. Lamellar corneal dissection is performed to 80% of the corneal depth to provide sufficient visibility for cataract surgery. Manual small-incision cataract extraction and intraocular lens implantation is performed through a frown-shaped scleral tunnel. Subsequently, 4 small penetrating incisions are made along the edge of the trephination mark at the 3, 6, 9, and 12 o'clock positions. A graft is placed on the ophthalmic viscosurgical device-coated stromal bed, and the 4 penetration sites are sutured. The stromal bed is cut along the trephination groove, the graft is sutured quadrant by quadrant, and the stromal bed is drawn out of the anterior chamber. The surgery is completed with 16 sutures.
我们描述了一种将穿透性角膜移植术与白内障手术相结合并维持安全前房的手术技术,用于处理并存的角膜混浊和白内障。进行板层角膜剖切至角膜深度的80%,以提供足够的视野用于白内障手术。通过皱眉形巩膜隧道进行手法小切口白内障摘除及人工晶状体植入。随后,在3点、6点、9点和12点位置沿环钻标记边缘做4个小的穿透切口。将植片置于涂有眼科粘弹剂的基质床上,并缝合4个穿刺部位。沿环钻凹槽切开基质床,逐象限缝合植片,然后将基质床从前房中取出。手术以16针缝线完成。
