An ophthalmological device for the treatment of keratoconus includes a cylindrical reservoir made of a non-conductive material, open at the top and bottom, and formed by two telescopically engaged portions, a lower one open at the bottom and connected to a cylindrical chamber of smaller diameter, also open at the bottom and formed by an external annular chamber that is concentrically arranged around the chamber and is closed at the top, open at the bottom, and adapted to be placed on the eye; a first metallic conductor, housed in the container and connected to a terminal of a DC voltage generator, to the other terminal of which a second metallic conductor is connected; a first conduit provided with a closing device, one end of the first conduit flowing into the annular reservoir, the other end being located externally thereto, whereby vacuum may be applied through the first conduit; and a second conduit provided with a closing device, one end of the second conduit passing through the annular reservoir at its lower edge and flowing into the container, the other end being located externally to the annular reservoir. During irradiation, a hydrating solution is administered from above through the metallic conductor that touches the eye and is released through the conduit to avoid the excessive absorption of incident energy by the hydrating solution while maintaining a minimum thickness and constant hydrating solution on the ocular surface.

An optical interface device having an opening for an optical path that can be non-circular and having engagement members having gradually varying angles of engagement. An embodiment of the interface device can be a one size fits all device, providing a configuration that fits in all typical eye openings, including narrow palpebral fissures and small eyes, while providing optical path access to features and structures of the eye. An embodiment of the interface device engages the limbus, cornea and sclera.

A device comprising: an elongated head having a distal end formed by an elongated edge of a cutting blade positioned in parallel with an elongated edge of a control blade, wherein the elongated edges of the respective control and cutting blades are separated by a uniform gap forming the distal opening to a channel running from an anterior end to a posterior end of the head, wherein the elongated edge of the cutting blade extends distally beyond the elongated edge of the control blade providing a height differential between the edge of the cutting blade and the edge of the control blade, wherein the edge of the cutting blade is sharp and configured to cut a bodily tissue, and wherein the edge of the control blade is dull and forms a barrier that limits the depth of penetration of the edge of the cutting blade into the bodily tissue.

A planning system for generating control data for a treatment apparatus which creates at least one cut surface in the cornea using a laser device, and a treatment apparatus which comprises a planning system of the aforementioned type. The invention also relates to a method of generating control data for a treatment apparatus which creates at least one cut surface in the cornea using a laser device, and to a corresponding method of eye surgery. The planning system comprises a calculation means for defining the cut surfaces of the cornea, wherein the calculation means determines the cornea cuts so that the cut surfaces isolate a lenticule, which is treated according to the planned refraction correction after removal from the cornea, so that the planned refraction correction occurs after the insertion into the cornea of the recipient.

The shaped corneal/other tissue/bioengineered material trephines can create single or combination of shaped cuts and sections in cornea, sclera or any other tissue or bioengineered material of desired shapes, thickness, width, depth, radius, sizes/dimensions, measurements and configurations. It can create certain patterned or shaped cuts in tissue including but not limited to cornea and sclera/bioengineered material without using the femtosecond laser, especially in the case of cornea where at present the femtosecond laser is required for this purpose. A manual or motorized trephine allows creating cuts in different shapes, thicknesses, width, depth, radius, sizes/dimensions, configurations and measurements with single/multiple or combination of cuts. These configurable cuts give the advantage of creating shaped incisions/sections in the body of a subject as well as give the ability to create donor and recipient sections of cornea, sclera or any other tissue or bioengineered material of specific shapes and dimensions. It therefore gives the ability to create these shaped cuts and sections of tissue without the need for a femtosecond laser and also ability to cut through tissue that is not necessarily transparent.

Zero parallax visual axis glasses for corneal pre-marking include a target light, an alignment light, a polarized lens and a short pass filter. In some embodiments the targeting light and/or alignment light are LEDs and/or configured to blink. In some embodiments the target light is red. In certain embodiments the alignment light is white. The polarized lens can be placed on a user's non-dominant eye and block light originating from the target light and/or alignment light. The short pass filter can be configured to allow light from the target light to only pass through in one direction.
