白内障的手术经过一千多年的发展,现在已趋向用手术显微镜作囊外摘除而反对囊内摘除。为了适应人工晶体的植入,这种由白内障囊内摘除改为囊外摘除的转变是必不可少的,因此我们提出晶状体前囊开窗囊外摘除白内障的设计,经反复讨论与实践,认为本方案既确实可靠又便于推广,经临床应用后认为有提请眼科界同道审议的价值。一、手术方式沿用一般局部麻醉后,在角膜缘作上方结膜瓣,将已切开的结膜推向上穹隆在结膜下固定上直肌。于角巩缘处作半切开,缝好三条予置线,于11点处刺入5×17号三角针,该三角针沿已散大的瞳孔缘划破晶状体前囊,该前囊呈园形破口,其直径为6 mm左右故命名为晶状体前囊开窗术。此时前房仍保持一定深度,用刀片及剪刀扩大角巩膜切口至角膜缘的2/5,作虹膜周边切除,用晶状体匙轻 Cataract surgery after more than a thousand years of development, has now been used for surgical removal of extracapsular cysts and removal of cysts. In order to adapt to the implantation of intraocular lens, this change from extracapsular cataract extraction to extracapsular cataract extraction is essential. Therefore, we propose anterior lens capsule extracapsular cataract extraction design, after repeated discussion and practice, that This program is both reliable and easy to popularize, after clinical application, there is a suggestion that the ophthalmology community should consider the value. First, the use of general anesthesia following surgical approach, the top of the corneal limbal conjunctival flap, will have been cut into the supracondylar conjunctival fixed upper rectus abdominis. Half of the angle at the edge of the margin for the incision, sewn a good three presets, punctured at 11 o’clock triangular needle 5 × 17, the triangular needle along the already scattered pupil edge of the anterior lens capsule was scribed, the anterior capsule was Park-shaped break, the diameter of about 6 mm so named as anterior capsule ophthalmoscopy. At this point anterior chamber still maintain a certain depth, with a scissors and scissors to expand the scleral incision to the limbus 2/5, iris resection, the use of lens spoon light
