大约二百年前,Thomas Young 发现晶体眼患者戴远用眼镜仍能阅读,故认为无晶体眼仍有调节存在。此后不少学者陆续报道了这一现象,并称之为“显性调节”。1950年,Bettman 结合病例分析并参照各家学说,对这一现象的机理做了综合性推论,而Nagazawa 又于1983年、1984年相继提出不同意见,故目前对此现象的机理尚无定论。近年来,随着人工晶体植入术的迅速发展,有必要对此现象进行深入研究,这对今后研究设计可调节性人工晶体将有所帮助。
About two hundred years ago, Thomas Young found that patients with crystalline eyes wearing glasses can still read, so there is still no regulation of aphakia exist. Since then, many scholars have reported this phenomenon one after another, and call it “dominant adjustment.” In 1950, Bettman made a comprehensive inference on the mechanism of this phenomenon by combining with the case analysis and referring to various theories. However, Nagazawa made different opinions successively in 1983 and 1984, so the mechanism of this phenomenon is inconclusive at present. In recent years, with the rapid development of intraocular lens implantation, it is necessary to study this phenomenon in depth, which will help to study the design of adjustable intraocular lens in the future.
