A full depth ophthalmic surgical system includes a femtosecond laser source and an optical coherence tomographer. The system is capable of performing surgical procedures along the entire length of the eye from the cornea to the retina. In one embodiment, the system uses a removeable focal point extension assembly to extend the reach of the focal point location of the laser beam to the vitreous humor of the eye. In another embodiment, the optical system of the ophthalmic surgical system is optimized to focus the laser beam and imaging light in the vitreous humor of the eye. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system uses the focal zone of the optical coherence tomographer beam as a proxy for the focal zone of the femtosecond laser source to. The system can be used to perform treatment in the vitreous humor, including treating floaters and liquification of the vitreous humor.

In certain embodiments, apparatus for self-aligning elements of coupled platforms includes a radially repulsive magnetic bearing. The radially repulsive magnetic bearing includes a first axially polarized magnet and a second axially polarized magnet that is concentrically disposed around the first axially polarized magnet and radially repulsive to the first axially polarized magnet. The radially repulsive magnetic bearing is configured to align a first element of a first platform with a second element of a second platform when the first and second platforms are coupled together.

Particular embodiments include, by a computing device, receiving one or more wavefront elevation maps for a patient's eye and identifying one or more attributes of the one or more wavefront elevation maps corresponding to vitreous floaters. The one or more attributes may include localized spatial variation of the one or more wavefront elevation maps; temporal variation among a plurality of wavefront elevation maps; and depth information indicating scattering of light from within the vitreous of the patient's eye. A machine learning model may be trained and utilized to characterize vitreous floaters based on the one or more wavefront elevation maps and other patient data. The wavefront elevation maps may be measured using an aberrometer. The aberrometer may be integrated with a LIDAR system to estimate depth of scattered light. A common laser light source may be used for both the aberrometer and the LIDAR system.

The assembly for laser treatment of ocular opacities consists of: a measurement system for obtaining depth information regarding ocular structures; a laser system; an eye-tracker unit; a display unit; and a control-and-operating unit. According to the invention, the control-and-operating unit is designed to determine, from the depth profiles, the depth of ocular structures relative to the depth of the laser focus, and, in particular for the retina and the capsular bag, to determine a blocked zone for the laser treatment. Furthermore, the control-and-operating unit is designed to generate, at least for the blocked zones of the retina and capsular bag and the laser focus, at least one tag in each case, the characteristic of which corresponds to the particular depth in the eye, in order to display these tags on the display unit and to overlay them with the live image. The invention relates to a partially automated therapy apparatus for laser treatment of ocular opacities in which two-dimensional views of the eye are combined with three-dimensional imaging from the measurement system.

A method and system perform an ophthalmic procedure on an eye having an optical path from the lens to the retina. An image of at least part of the eye is received in a data processing unit. The image includes the optical path. The data processing unit determines keep out zone(s) and identifies undesirable feature(s) based on the image. The keep out zone(s) include the retina. The data processing unit also selects one of the undesirable feature(s) for removal. At least part of the undesirable feature is outside of the keep out zone(s). Confirmation for removal of the undesirable feature is received in the data processing unit. In response to receiving the confirmation, a control unit controls a laser to perform laser removal the at least the portion of the undesirable feature without targeting any portion of the keep out zone(s).

An arrangement for OCT-based laser treatment of vitreous floaters. The arrangement for OCT-based laser vitreolysis includes an OCT system, a laser system having a deflection unit, optical elements that couple the OCT system and the laser system, a display unit and a central control and operating unit.
