在先天性白内障手术中,能将足够大的晶体前囊完整切除,既可以克服抽吸皮质时所遇到的困难,又可以避免由于对晶体囊膜的牵拉而增加对周边部视网膜的牵引力。对预防术后发生后发性白内障和视网膜脱离有着十分重大的意义。然而,国内目前使用的截囊刀,破囊钩和自制的破囊针头,均由于反复长期使用,其锐利程度差,未能达到上述要求。Nd:YAG 激光的出现,给晶体前襄按预计的大小完整地切除带来了美好的前景,使原来使用器械破囊时感到困难的手术步骤成为轻而易举的操作,缩短了手
In congenital cataract surgery, can be large enough to complete the anterior lens excision, both to overcome the difficulties encountered when aspirating the cortex, but also to avoid due to the stretching of the crystalline capsule on the peripheral retinal traction . It is of great significance to prevent postoperative cataract and retinal detachment. However, the current domestic use of the capsulotomy knife, broken bag hook and homemade broken needles, due to repeated long-term use, the sharp degree of poor, failed to meet the above requirements. The advent of Nd: YAG lasers has given the crystal prospectively the prospect of complete resection to the expected size and offers a promising future that makes surgical procedures that were previously difficult to use when the instrument was ruptured and made it a breeze
