先天性白内障中常见的有绕核性白内障、核性白内障,多为双眼、静止性,也有出生后继续发展,在儿童或少年期始对视力有影响。混浊明显、范围超过瞳孔区,视力障碍较重时,多主张鼻下方光学虹膜切除术。尽管手术很成功,术后均无明显增视,所以先天障中心固视的术式有必要讨论一下。夏氏首次应用角膜映光法检查先天性白内障,提出中心固视先天障,采用晶体摘除术或吸出术者为合理。采用鼻下方(定点)虹膜切除术者为不合理。这是新的论点,经临床验证,具有重要的临床使用价值。
Common in congenital cataract around nuclear cataracts, nuclear cataracts, mostly binocular, rest, but also continue to develop after birth, in the beginning of childhood or young have an impact on vision. Obvious opacity, the scope of over the pupil area, severe visual impairment, and more advocate the lower nasal optical iridectomy. Although the operation is very successful, no significant increase after surgery, so the center of congenital fixation technique is necessary to discuss. The first application of corneal keratometry map examination of congenital cataracts, proposed center fixation of congenital defects, the use of crystal removal or aspiration surgery is reasonable. Under the nose (fixed-point) iris excision is unreasonable. This is a new argument, clinically proven, with important clinical value.
