Extracapsular cataract extraction of imported crystals

Modern extracapsular cataract extraction is the inevitable result of the development of modern ophthalmic microsurgery technology and the development of posterior chamber intraocular lens implantation technology. Compared with traditional extracapsular cataract extraction, the outstanding feature of modern extracapsular cataract extraction is the application of microsurgery and closed injection-suction system, which is less blind and traumatic, which makes the cataract surgery both surgically and surgically effective. In the past, they have entered a new stage that no previous method can match. Modern extracapsular cataract extraction combined with intraocular lens implantation has quickly gained popularity due to its advantages such as simple operation, safety, few complications, and one-stage correction for non-phakic eyes. In the early 1980s, modern extracapsular cataract extraction techniques were introduced to China. Since then, with the joint efforts of fellow ophthalmologists, it has been rapidly popularized and improved. By the mid-to-late 1980s, the development of domestic microsurgery had formed a considerable scale. Almost at the same time, a new concept of modern surgery-phacoemulsification cataract extraction has gradually become popular in clinical practice. The 1990s was the fastest developing period of phacoemulsification cataract extraction technology. Almost 95% of cataract doctors in developed countries are proficient in this technology. Although the development of modern cataract surgery technology in China is not very balanced, after unremitting efforts, the overall level has basically remained the same as that of developed countries. Many domestic scholars continue to explore modern extracapsular cataract extraction techniques. The most prominent feature is the non-phacoemulsification cataract extraction with a small incision using phacoemulsification based on the basic characteristics of extracapsular surgery. This operation not only requires the surgeon to have proficient extracapsular cataract surgery techniques, but also requires mastering phacoemulsification techniques such as tunnel incision, capsulorhexis, water separation, and nuclear splitting, which has advanced modern extracapsular cataract surgery techniques Stride.
