A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10-4 Pa*m3 to about 5×10-4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

The disclosure relates to the use of contact lenses for treating ophthalmologic conditions, such as presbyopia, induced myopia, computer vision syndrome, insufficient accommodation, or a condition associated with insufficient accommodation. The contact lens may be selected based on a measured sagittal depth and/or eccentricity of the cornea. When fitted, fluid may accumulate between the cornea of the eye and the contact lens The lens may exhibit a sufficient amount of apical clearance such that when the wearer blinks, the lens moves no more than 1 mm on the eye. The lens and the eye may be structured such that bubbles greater than 0.5 mm in diameter are prevented from forming between the contact lens and the eye. The contact lens may be used in combination with a suitable bioactive agent providing for enhanced visual correction.

The present disclosure relates generally to dry inks for use in marking the eye prior to surgery and methods of applying the same to eye marking devices. Such inks can include various accepted inks for use on the eye that can be applied to a marking device using relatively fast-evaporating solvents. In this manner, the remaining ink composition can be precisely placed on the eye marking device, and desirably transfer to the marking surface of the eye without dissolving on the journey through the various membranes above the marking surface. Application methods may include use of charged ink particles that may be advantageously manipulated using magnetic fields to even more precisely place the dry ink on a marking device.

The present invention relates to an ophthalmic knife and methods of its use for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. The device is configured for cutting the tissues within the eye, for example, a trabecular meshwork (TM).

A dissection system for corneal transplants includes a housing including a contact side to be positioned against a cornea. The housing includes an interior passageway with an opening at the contact side. The dissection system includes a blade assembly disposed in the interior passageway. The blade assembly includes a first blade and a second blade. The first blade includes a first cutting edge and the second blade includes a second cutting edge. The first blade and the second blade are movable relative to the housing such that the first cutting edge and the second cutting edge extend through the opening of the housing and out of the interior passageway. The first cutting edge produces a first cut in the cornea. The second cutting edge produces a second cut in the cornea. The first cut and the second cut define a volume of tissue for removal from the cornea.

A donor corneal tissue cutting blade provided with integrally formed asymmetrical markers for facilitation identification of the anterior and posterior sections or portions of the donor corneal tissue is disclosed. The blade is a cylindrical body having, in one embodiment, a U-shaped extension which cooperates with the body to define a keyway. Protrusions may be formed on the body and/or extension to provide further markers.

Particular embodiments disclosed herein provide a membrane delamination device for delaminating a membrane from a retina of an eye. The membrane delamination device comprises a blade, a first lever coupled to the blade, and a second lever coupled to the blade. The first lever and the second lever are at least partially housed by a first shaft of a hand-piece. The first lever is fixedly coupled to the first shaft. The second lever is fixedly coupled to the hand-piece. The blade at least partially extends beyond a distal end of the first shaft. The membrane delamination device is configured to be actuated as a result of longitudinal movement of the second lever within and in relation to the first shaft. The second lever moves longitudinally within and in relation to the first shaft due to an application of force to the second lever through the hand-piece.

The present invention relates to an ophthalmic knife and methods of its use for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. The device is configured for cutting the tissues within the eye, for example, a trabecular meshwork (TM).

The present invention provides methods and systems for an eye marker device that includes a handle and an eye marker tip, wherein the eye marker tip includes at least two arms dimensioned for placing at least one mark or indicator on a cornea, sclera or sclera/cornea junction.

A surgical device for cutting a lens within a capsular bag of an eye. Related methods, systems, and devices are also provided.
