白内障吸取术目前已公认为治疗先天性白内障及晶体核密度尚不足以引起问題的青年性白内障所选用。为此手术曾设计有多种器械。其中很多涉及到吸出液体的精确置换,避免术中前房消失。随着备有助手观察目镜的手术显微镜的应用,以及适当助手的配合,完全可能用一个空针缓缓往前房注入液体,同时用另一空针吸出液体及晶体皮质,在整个手术中保持前房深度。作者介绍一种改进的双套管,这一对针头平行焊在一起,一个针头比另一个错后一些(如图),较长的针头藉Luer接头和2ml空针相接,较短的管连接15厘米的硅胶软管藉Luer接头与第二空针相连;包好,消毒,备用。术前充分散瞳,不需虹膜切除。颞侧或上方角膜缘内作2毫米切口,重要的是切口不可过大,否则液体自针管周围溢出,难以保持前房。必要时可用Worst氏U字缝线,但稍有些漏 Cataract surgery is now recognized as the treatment of congenital cataracts and the nucleus density is not enough to cause problems of youth cataract selected. For this surgery has designed a variety of instruments. Many of these involve precise replacement of the aspirated fluid to avoid the disappearance of the intraoperative anterior chamber. With the use of a surgical microscope equipped with an assistant to observe the eyepiece and with the help of a suitable assistant, it is entirely possible to slowly pour liquid into the anterior chamber with an empty needle while aspirating the liquid and crystalline cortex with another empty needle, keeping the front Depth of room. The authors describe an improved double bushing that is welded together in parallel with one needle behind the other (pictured), a longer needle connected to a 2 ml needle by a Luer fitting and a shorter tube Connect a 15 cm silicone hose to the second empty needle via a Luer fitting; wrap, disinfect, and back-up. Dilated preoperative full, no iris resection. Temporal or upper limbal margin 2 mm incision, it is important not to incision is too large, or liquid spilled from around the needle, it is difficult to maintain the anterior chamber. Use Worst’s U-shaped suture when necessary, but slightly leaky
