This disclosure relates to surgical instruments and methods for incising soft tissue. The instruments may include one or more atraumatic features for reducing a likelihood of trauma to adjacent tissue.

A system (20) includes a radiation source (48) and a controller (44). The controller is configured to define a treatment zone (88) on a capsular bag (86) of an eye (25) of a subject (22), and to form an opening (96) in the capsular bag by irradiating a plurality of target site regions (94) within the treatment zone in an iterative process after the treatment zone is defined, the iterative process including, during each of a plurality of iterations of the process, acquiring an image (98) of at least a portion of the capsular bag, designating one of the target site regions based on the acquired image, and causing the radiation source to irradiate the designated target site region. Other embodiments are also described.

A surgical device and procedure are provided for smoothly and easily accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision in the cornea of the eye. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position on the lens capsule. A cutting element mounted to the suction cup is used to cut a portion of the lens capsule and to remove the portion from the eye. The cutting element may be mounted to a cutting element support structure in a way that prevents heating of the device.

A capsulorhexis device is 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 having elasticity and conductivity; a moving member having one end fixed and coupled to the loop; an insertion guide configured so that, while the incision is being made in the crystalline lens capsule, a front end thereof is inserted into the incision site of the cornea; and a housing having one end coupled to a rear end of the insertion guide, wherein the loop is housed in the housing and, to make the incision in the crystalline lens capsule, slides in the housing together with the moving member to pass through the insertion guide and be deployed into an anterior chamber of the eye.

The utility model discloses a capsulotomy device, which belongs to the technical field of medical supplies and comprises an injection tube, the hollow conical head is in threaded connection with the injection tube, and a capsulotomy ring is placed in the conical head; the two limiting pipes and the two mounting pipes are arranged on the periphery of the injection pipe, and connecting ring plates are fixedly connected between the limiting pipes and the mounting pipes; the multiple movable plates are arranged between the two limiting pipes, the side faces of the movable plates are connected with clamps, the clamps are fixedly provided with lamps used for illumination, and the side faces, away from the clamps, of the movable plates are connected with arc-shaped plates matched with the peripheries of the injection pipes; an elastic arc-shaped rubber pad is bonded to the side face, close to the injection pipe, of the arc-shaped plate, two magnet blocks are bonded to the periphery of the movable plate, the two limiting pipes are made of iron materials capable of being attracted to the magnet blocks, an anti-skid pad is bonded to the inner wall of the mounting pipe, and a plurality of threaded channels are formed in the periphery of the mounting pipe. The capsulotomy device can be adjusted to different degrees, and illumination to different degrees is achieved.

The invention relates to a modular Modular Laser Therapy Device (MLTD) to be used by ophthalmologists for eye surgery that integrates three most frequently used therapeutic devices into a single, compact unit enabling the treatment with capsulotomy, vitreolysis and iridotomy, with selective laser trabeculoplasty and with photocoagulation. While providing such modular laser device a method is provided for optomechanically coupling different ophthalmic modules into the single unit using two laser sources.

Methods and systems for performing laser-assisted surgery on an eye form one or more small anchoring capsulotomies in the lens capsule of the eye. The one or more anchoring capsulotomies are configured to accommodate corresponding anchoring features of an intraocular lens and / or to accommodate one or more drug-eluting members. A method for performing laser-assisted eye surgery on an eye having a lens capsule includes forming an anchoring capsulotomy in the lens capsule and coupling an anchoring feature of the intraocular lens with the anchoring capsulotomy. The anchoring capsulotomy is formed by using a laser to incise the lens capsule. The anchoring feature can protrude transverse to a surface of the intraocular lens that interfaces with the lens capsule adjacent to the anchoring capsulotomy.
