白内障显微手术的目的是使手术者看得更清楚,应用更精细的器械,更细的缝线,细致的操作使组织损伤达最少限度,从而为术后恢复良好的视力创造有利条件。但显微手术的器械设备要求较高,手术时间较长,我国目前多数医院病人多,显微镜还未普遍使用,推广显微手术有一定的困难。我们采用3～5倍的双眼放大镜,用9～0或10～0的单股尼龙线作白内障次显微摘除获得良好效果,现报导如下: 器械准备:一个放大3～5倍的放大镜,9～0或10～0的带三角针的单股尼龙线,一把显微手术的持针器,一把较好的角膜镊,其余的器械同白内障囊内摘除。手术要点:病人准备同一般白内障囊内摘除。手术过程包括:1.术前应给病人充分镇静药,以加强麻醉药的作用,如用安定10mg和鲁米那100mg
The purpose of cataract microsurgery is to make the surgeon see more clearly. The application of finer instruments, thinner sutures and careful operation can minimize tissue damage and create favorable conditions for the recovery of good visual acuity after surgery. However, the requirements of microsurgical instruments and equipment are higher, and the operation time is longer. At present, most of the hospital patients in our country have many microscopes that have not been used universally, and the promotion of microsurgery has some difficulties. We use 3 to 5 times the binocular loupe, with 9 to 0 or 10 to 0 single nylon line for cataract subtotal microsurgery to obtain good results, are reported as follows: Equipment preparation: a 3 to 5 magnification magnifying glass, 9 ~ 0 or 10 ~ 0 with a single needle nylon needle line, a microsurgery needle holder, a good corneal tweezers, the remaining instruments with the cataract capsule removal. The main points of surgery: patients with the same general cataract cyst removal. Surgical procedures include: 1. Preoperative patients should be fully sedated drugs to enhance the role of anesthetics, such as the stability of 10mg and luminal 100mg
