A device for mechanically assisting with scleral depression is disclosed. A top ring and a bottom ring are rotationally engaged where the bottom ring is capable of attachment to an eyelid speculum, and is thus fixed while in use. A variable vertical displacement apparatus is attached to the top ring. A rod and depressing member are engaged with the variable vertical displacement apparatus such that the depressing member is capable of both vertical and horizontal travel around the periphery of a patient's eye, allowing a surgeon to depress the sclera of a patient's eye while at the same time performing a surgical procedure.

Mechanical optics for mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A mechanical optical element, such as a rotating prism or a mirror membrane, may impart motion to an incident beam entering the optical fiber to generate a homogeneous illumination field from a coherent light source.

Apparatus for performing an ocular surgery, the apparatus comprising: a support housing having a bottom configured to be positioned on the sclera of an eye during performance of an ocular surgery; a muscle hook holder connected to the support housing and configured to hold an ocular muscle hook so that the ocular muscle hook is translatable to elevate an ocular muscle away from the eye during performance of the surgery; and a set of graduation markings on the support housing useable to determine a distance that the ocular muscle hook is translated to elevate the ocular muscle.

A contact lens assembly for non-sliding, non-sutured, hands-free ophthalmic procedures utilizes a magnetically actuated anchoring mechanism operatively coupled between the contact lens assembly and a modified eye speculum applied to eyelids during ophthalmic procedure. The anchoring mechanism is configured with magnetically cooperating anchoring members, one coupled to the contact lens assembly, and another secured to a wire loop member of the modified eye speculum. After the eye speculum is applied to the eyelids to displace and stabilize the eyelids and secure the anchoring member in place, and the contact lens assembly is placed on the cornea of the eye and centered, he magnetically cooperating anchoring members are brought in contact, and thus secure the contact lens assembly at the surgical site.

The present disclosure generally relates to illumination systems for surgical procedures, and more particularly, non-invasive trans-scleral illumination systems for ophthalmic surgical procedures. In one embodiment, an illumination system includes a speculum having two arms coupled to blades at distal ends thereof and a biasing member at proximal ends thereof. One or more optical fibers are disposed through at least one of the arms and have one or more termination points located within at least one of the blades. The optical fibers are configured to deliver light to an interior space of an eye when the eye is coupled to the speculum. In some embodiments, the illumination system further includes a temple support pad.

Apparatuses, systems, and methods are provided herein to control movement of a patient's eyelid during a diagnostic procedure such as scanning the patient's eye with an ultrasound or optical imaging device. Strips having a non-adhesive portion and an adhesive portion are attached to each eyelid. The patient can then pull on distal ends of the strip to open the patient's eye and press the strips into an eyepiece to hold the patient's eyelids and keep the patient's eye open.

A pupil expander is formed from a frame of shape-memory material with a covering made of elastomer. The frame is in the form of two arc-shaped sections connected together at one end to form a broken circle having free distal ends. Each arc-shaped section has an upper frame portion and a lower frame portion connected to each other at the distal ends thereof. The covering is disposed over each arc-shaped section and has a C-shaped cross section so as to form an outwardly facing groove between the upper frame portion and the lower frame portion. The pupil expander is configured to be folded in half with the grooves facing each other and straightened so as to form a cylindrical body for insertion into a tubular applicator and upon release from the applicator, the pupil expander resumes the shape of the broken circle to push the margins of the pupil wider.

This invention pertains to the field of medical diagnostics which is used to take a sample of blood vessel, called BLOOD VESSEL SAMPLE, for investigation purposes. The blood vessel sample kit composed of flexible clips attached with the stand, having tooth on the lower surface on either side of the clips. The blood vessel sample kit also having a triple scissors with a spring handle and three sets of upper and lower blades, purposed to cut off a small portion of the blood vessel, to make the vascular endothelium exposed, easy for culturing. The blood vessel sample is taken from the VISIBLE VASCULAR WEB of the SUPRA TENON VASCULAR WEB. The purpose of the blood vessel sample taking is to study the VASCULAR ENDOTHELIAL RESPONSE TO DIABETESVERD, which is a part of conjunctival vasculopathy.

An orbital tissue retractor 10 for use in a surgical operation in the region of an eye socket, comprises an orbital tissue retractor body 12 and a handle 14 extending therefrom for manipulation of the tissue retractor body by a surgeon. The tissue retractor body comprises a channel formation 16 defining a channel 17. The channel formation 16 has a pair of spaced side wall sections 24 which define concave curved ocular abutment formations 26 which conform to an anatomical curvature of the ocular globe for abutment with the ocular globe N. The tissue retractor body has open proximal end 22 and an open distal end 20. The tissue retractor body tapers from the proximal end to the distal end, with a portion of the channel formation at the distal end being curved so as to accommodate and cradle the optic nerve therein. The retractor body has a curved base wall section 28 conforming to an anatomical curvature of the orbit.
