摘要:
Die Kenntnis der anatomischen, postoperativen Position und Lage beeinflusst nicht nur die Auswahl der zu implantierenden IOL sondern auch das Ergebnis des refraktiven Eingriffs am Auge. Bei dem Verfahren zur Auswahl einer in ein Auge zu transplantierenden IOL, basierend auf der Vorhersage deren anatomischer, postoperativer Position (ALP) und Lage auf der Basis präoperativer Messwerte, wie beispielsweise Vorderkammertiefe (VKT), Linsendicke (LD) und Augenlänge (AL) werden erfindungsgemäß zusätzlich oder ausschließlich die Krümmung(en) der Augenlinse oder daraus abgeleiteter Messwerte verwendet. Das vorgeschlagene Verfahren dient der Vorhersage der anatomischen, postoperativen Position (ALP) und Lage einer in ein Auge zu transplantierenden Intraokularlinse (IOL). Im Gegensatz zu Verfahren, die nur eine virtuelle Position der IOL ermitteln, wird mit dem erfindungsgemäßen Verfahren die tatsächliche postoperative Position und Lage einer IOL beschrieben, die beispielsweise für weitere Verfahren, wie das Raytracing zwingend erforderlich sind.

摘要:
Artificial lenses and methods for optimizing vision in an eye of a patient comprising the steps of determining a target optical configuration including the optimum defocus and aberrations that the patients' eye should have in order to match or approximate the original optical configuration of the patient; determining the refractive change of the patient's eye required to achieve the optical configuration best corresponding to target optical configuration for the patient; and implementing the selected refractive change to achieve the target optical configuration.
摘要:
A method of generating a patient-specific prosthetic includes receiving anatomic imaging data representative of a portion of a patients anatomy. A first digital representation of the anatomic imaging data is defined. The first digital representation of the anatomic imaging data is modified. A second digital representation of the portion of the patients anatomy is defined based on the modifying of the first digital representation of the anatomic imaging data. A patient-specific prosthetic template of the portion of the patients anatomy is generated based at least in part on the second digital representation of the anatomic imaging data.
摘要:
This disclosure features elongated prosthetic devices that can be used to repair, e.g., resurface or occlude, a defect of a semicircular canal, e.g., a superior semicircular canal dehiscence, as well as methods of making and using these devices. For example, the devices can be made using three-dimensional (3D) printing.
摘要:
A delivery system for forming a stent in-situ may comprise an elongate shaft having a proximal end and a distal end and a lumen extending from the proximal end towards the distal end of the elongate shaft. A plurality of apertures may be positioned adjacent to a distal end region of the elongate shaft. The plurality of apertures may extend from an outer surface to an inner surface of the elongate shaft and be in fluid communication with the lumen. A port may be affixed to the proximal end of the elongate shaft and in fluid communication with the lumen.
摘要:
An assembly including a deployment device for deploying a stent device into an aorta of a patient is provided. The deployment device includes a rod translatable within an aorta of a patient and a first release wire configured for releasing one or more radially constraining members, wherein the radially constraining members are configured to constrain a diameter of the stent device. The stent device is at least partially permeable and engaged with the deployment device in an initial configuration, wherein a diameter and a length of the stent device in a deployed configuration can be altered by axial translation of the rod and releasing one or more of the radially constraining members by translation of the first release wire.
