| 摘要 |
The invention relates to a method and a device for preoperatively predicting a postoperative horizontal depth (postope IOLE, postope IOLE*) of an intraocular lens (14, 14') in a patient's eye (1). Parameter values are provided, said parameters including a first parameter as the depth (preopACD) of an anterior chamber (7) of human eyes, a second parameter as a horizontal length (preopAL) of human eyes, and a third parameter as a postoperative position of intraocular lenses in human eyes. Specific triplets of values are selected from said values as main interpolation nodes (18 to 33), each triplet of values comprising a value for each of the three aforementioned parameters, and the main interpolation nodes (18 to 33) are entered into a three-dimensional coordinate system that is spanned by the three parameters. The main interpolation nodes (18 to 33) are connected by edge connecting lines (34 to 57), and a predictive network (58) that is unevenly formed in the three-dimensional coordinate system is generated at least using the positions of the edge connecting lines (34 to 57) in order to predict the postoperative horizontal depth (postopeIOLE, postopeIOLE*) of the intraocular lens (14, 14') in the patient's eye (1). |
