摘要： Postoperative lens position is predicted on the basis of known measured values, such as the corneal thickness, the depth of the anterior chamber, the eye length, and the distances of the capsular bag equator and/or of the lens haptic from the anterior surface of the lens. In addition, the calculation also takes into account the attitude of the intraocular lens, for which purpose additional parameters of the pseudophakic eye are used that have not previously been taken into consideration. The proposed method is suitable for a more exact prediction of the strength and nature of an intraocular lens to be implanted in a pseudophakic eye in the context of cataract surgery or of a refractive intervention. The method is based on the use of suitable calculation methods, e.g. geometric optical formulae, or of ray tracing.

摘要： An ophthalmological laser system and operating method wherein laser-supported operative interventions can be achieved with higher accuracy. The cornea is irradiated with an ophthalmological laser and a detection light confocally recorded, the cornea being scanned in three-dimensions by irradiation with an illuminating laser power using a scanner unit along several directions at several points. Using the simultaneously recorded detection light the position and/or shape of a posterior boundary surface of the cornea is determined. A lamella parallel to the posterior boundary surface can then be cut.
