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

In certain embodiments, a system for performing refractive treatment of an eye comprises a laser, a printer, and a computer. The laser emits a laser beam to prepare the eye for the refractive treatment. The printer prints material onto a print area of a target. The printer comprises a printer head and a printer controller. The printer head directs the material onto the print area, and the printer controller moves the printer head to direct the material onto a specific location of the print area. The computer comprises a memory and processors. The memory stores instructions for a pattern for the target. The pattern is designed to provide the refractive treatment for the eye. The processors instruct the printer controller to move the printer head to print the material onto the print area according to the pattern.

A method of sutureless intrascleral haptic-hook lens implantation which improves the fixation process of the lens haptics, allowing the lens haptics to be bent and folded back into the vitreous cavity to generate a better stability, avoiding the complication of intrascleral fixation haptic slippage, meanwhile forming a sclera lamellar groove between two adjacent scleral incisions to bury the lens haptics. The method may be adapted to patients in need of intraocular lens implantation without sufficient capsular support, such as aphakia, intraocular lens, lens dislocation, etc. This method enhances the stability and centrality of the lens, the surgical procedures are simple and easy to master, which reduces the operation time.

Improved corneal lenticule extraction tools which integrate defined angles, tip features, and the use of vacuum into the tool to aid in the removal of the lenticule. The tool has a body and a tip each with an internal air channel. The tip has a straight portion and a curved portion at a distal end, with one or more orifices disposed on the curved portion. The body either has a mechanism for generating a vacuum in the internal air channel, such as a resilient diaphragm, or is connected to an external vacuum source. Use of tip features and angles helps the surgeon find tissue edges during tissue removal. The use of vacuum aids to draw the tissue to the tool and to hold the tissue by the tool. The improved tools improve speed of extraction as well as completeness of extraction so that no tissue is left behind.

Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.

An orthokeratology lens designating system 10 includes a selecting device 20, a database server 30, a lens designating server 50 and a terminal device 70. The selecting device 20 includes a device 22 for acquiring movement data of an orthokeratology lens moving on a cornea with the orthokeratology lens mounted on the cornea, and an assessing device 28 for assessing, on the basis of the lens movement data, that the orthokeratology lens is a registered lens that can be used for a patient. Registered lens correction D data of the registered lens, registered patient data including registered cornea D data of a cornea, and registration stage data that indicates in which stage of a plurality of correction stages, the lens is to be mounted on the cornea, are output to the database server 30. The database server 30 is configured to accept and store these pieces of data to build a database. The terminal device 70 includes a patient data acquiring device 71 and a patient stage data accepting means, and is capable of transmitting patient data and patient stage data to the lens designating server 50. The lens designating server 50 is configured to retrieve from the database a registered lens having registered data that are the same as or close to the received patient data and patient stage data, and to designate the retrieved registered lens as the orthokeratology lens to be used for the patient.

Provided herein is a capsulorhexis device (100) inserted into an incision site of a cornea to make an incision in an anterior capsule surrounding a crystalline lens. The capsulorhexis device includes a loop (110) having elasticity and conductivity, a moving member (120) having one end fixed and coupled to the loop (110), a head part (130) including a housing configured to store the loop (110) therein and an insertion guide (131) coupled to one end portion of the housing to communicate therewith, and a body (140) that is coupled to the other end portion of the housing and has a sliding button (141) provided to slide the loop (110) and the moving member (120) through the head part (130). In order to make the incision in the anterior capsule, a front end of the insertion guide (131) is configured to be inserted through the incision site of the cornea, the head part provides a path along which the loop (110) is moved to the outside through the insertion guide (131), and the loop (110) slides to pass through the insertion guide (131) from the housing, is unfolded into an anterior chamber of the eye that is below the cornea, and is configured to, using high-frequency power supplied thereto, make a circular incision in a site of the anterior capsule that comes in contact with the loop (110).

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.
