Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

A patient interface for an ophthalmic laser system includes an interface portion and an attachment portion. The interface portion includes a transmissive portion and an interface wall. The transmissive portion allows a laser beam through to the cornea of an eye to perform an ophthalmic procedure. The interface wall is disposed outwardly from the transmissive portion. The attachment portion couples the interface portion to a region of the cornea to allow the laser beam through to the cornea to perform the ophthalmic procedure. The attachment portion also decreases the temperature of the region during the ophthalmic procedure.

A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

A vacuum device comprises a vacuum generator and a vacuum interface for fluidically coupling the vacuum generator to a vacuum cavity for affixing an ophthalmological patient interface on a patient's eye. The vacuum device comprises a movement detector which is configured to detect movements of the patient's eye and a control unit that is configured to detect a faulty fluidic coupling of the vacuum cavity on the basis of a pressure that is ascertained by a coupled pressure sensor and to produce a control signal for interrupting an ophthalmological treatment that is carried out by an ophthalmological treatment device if an eye movement is detected by the movement detector at the same time as the detected faulty fluidic coupling of the vacuum cavity.

An occular lens, such as a laser lysis lens, is provided that is suitable for use in viewing and lysing sutures in ophthalmic procedures. The occular lens includes a lens body having an the eye contacting surface. The eye contacting surface includes a groove or slot configured to aid in localizing and fixating a ligated drainage tube of a drainage implant during ligation/suture removal.

An ophthalmic system may comprise an imaging device having a field of view oriented toward the eye of the patient; a patient interface housing defining a passage therethrough, having a distal end coupled to one or more seals configured to be directly engaged with one or more surfaces of the eye of the patient, and wherein the proximal end is configured to be coupled to the patient workstation such that at least a portion of the field of view of the imaging device passes through the passage; and two or more registration fiducials coupled to the patient interface housing in a predetermined geometric configuration relative to the patient interface housing within the field of view of the imaging device such that they may be imaged by the imaging device in reference to predetermined geometric markers on the eye of the patient which may also be imaged by the imaging device.
