20100060728 | METHOD FOR PRODUCING HIGH-QUALITY REPRODUCTIONS OF THE FRONT AND/OR REAR SECTIONS OF THE EYE - The present invention makes it possible to make high-quality recordings of the anterior and/or posterior segments of the eye as an individual image or also as a sequence of images without increasing the radiation load on the eye to be examined. In the method according to the invention, at least one pre-flash is used in order to determine an optimal exposure time for the main flash based on the recording of the pre-flash which is reflected by the object to be recorded. Both the pre-flash and the main flash are controllable and the recordings of the pre-flash and main flash are recorded with the same sensor of the electronic camera and are evaluated electronically by a control unit, and the recording of the main flash and, as the case may be, of the pre-flash is analyzed and/or corrected and displayed to the user. | 03-11-2010 |
20110058715 | METHOD FOR THE CREATION OF PANORAMIC IMAGES OF THE EYE FUNDUS - A method for creating or calculating panoramic images of the eye fundus particularly from images of a fundus camera. In the method a pre-positioning process is carried out in which a first variable is determined for geometrically associating the images with each other. An anchor image is determined as a reference for the first variables for the geometric association; areas that are associated with each other are determined in the anchor image and the other images by a block-matching algorithm; transformation parameters for a geometric transformation between the anchor image and the other images are determined from the mutual position of the associated areas; and the other images are transformed onto the anchor image by transformation parameters and are superimposed onto the anchor image and among each other. | 03-10-2011 |
20140125955 | METHOD FOR OPTIMIZED PREDICTION OF THE POSTOPERATIVE ANATOMICAL POSITION OF AN INTRAOCULAR LENS IMPLANTED IN A PSEUDOPAKIC EYE - 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. | 05-08-2014 |
20140192317 | METHOD FOR THE PRE-OPERATIVE SELECTION OF AN INTRAOCULAR LENS TO BE IMPLANTED IN AN EYE - A method for the preoperative selection of an intraocular lens to optimise the results of refractive surgery on the eye. On the basis of an eye model comprising the individual biometric parameters of the eye, potentially suitable IOLs are selected on the basis of their optical parameters such as optical power, asphericity and toricity, and the residual refraction of potentially suitable IOLs is calculated using ray tracing. Various metrics, preferably retinal image metrics, are used to calculate the residual refraction and in order to improve the selection, at least one additional parameter is taken into consideration for the calculation, said calculation taking the postoperative effects of the selected IOL and/or of the surgical technique used into account. | 07-10-2014 |

At least the corneal topography, the length of the eye and the depth of the anterior chamber are determined pre-operatively, the values of the IOL to be implanted are calculated by means of ray-tracing, and at least the corneal topography, the length of the eye, the depth of the anterior chamber and the objective, wavefront-based residual refraction are determined post-operatively. The measurement values determined pre-operatively and post-operatively are used to optimize the surgically-induced astigmatism and the post-operative anatomical lens position for calculating the values of IOLs to be implanted in the future. | 11-06-2014 |
