At cataract operation, the opaque cataractous lens is removed from the eye and is replaced by an artificial intraocular lens. Employing modern technology, development of a bifocal intraocular lens based on diffraction optic has now proved possible. The lens contains correction for distant vision and also for close work so that the patients may be independent of glasses. Sixty-two eyes with bifocal intraocular lenses were followed-up for approximately one year. The results are promising. 84% of the patients could read small print without corrective glasses. The accuracy by which the intraocular lens power can be calculated preoperatively and the surgical control of astigmatism in the eye are of decisive importance for the success of the lens.
在白内障手术中，将不透明的白内障晶状体从眼中取出，并用人工晶状体取而代之。利用现代技术，现已证明开发基于衍射光学的双焦点人工晶状体是可行的。这种晶状体包含了对远视力和近视力的矫正，从而使患者无需佩戴眼镜。对62只植入双焦点人工晶状体的眼睛进行了约一年的随访。结果很有前景。84%的患者无需矫正眼镜就能阅读小字体。术前计算人工晶状体屈光度的准确性以及对眼睛散光的手术控制对晶状体植入手术的成功至关重要。
