In general, embodiments of the present disclosure relate to pigment containing contact lenses, such as colored contact lenses. In particular, embodiments of the present disclosure relate to a silicon hydrogel (SiHy) contact lens having a layered configuration that completely encapsulates a layer of pigment. In at least some embodiments, a method for forming a contact lens is provided. The method includes applying a clear ink to at least an iris portion of a mold and curing the clear ink with UV light to form a clear ink layer. The clear ink includes about 38 wt % to about 70 wt % of a polymer binder. The method further includes, applying, via pad printing, at least one pigmented layer onto the cured clear ink layer, and curing the at least one pigmented layer with UV light to form a lens assembly.

An ophthalmic surgical system for monitoring incision performance includes a laser device, a camera, and a computer. laser device delivers a laser beam with a laser setting energy towards a target to create optical breakdowns in the target. The camera generates images of the optical breakdowns in the target. The computer instructs the laser device to create the optical breakdowns in the target to yield a test pattern. The test pattern comprises regions of optical breakdowns, where each region was created with a different laser setting energy. From the images, the computer identifies a lowest energy region with substantially continuous optical breakdowns, and designates the laser setting energy used to create the identified region as a threshold energy.

A method for treating near-retina floaters includes dilating a pupil of an eye of a patient to at least 6.6 millimeters (mm). While the pupil is dilated to at least 6.6 mm, the method further includes emitting, by an optical delivery system, a plurality of pulses from a treatment laser into the eye of the patient, each pulse of the plurality of pulses having a diameter upon passing through the pupil that substantially fills the pupil and having a focus within 3 mm of a retina of the eye of the patient. Pulses may pass through adaptive optics that may be adjusted based on light emitted from the eye, such as two-photon fluorescence or second harmonic radiation, in order to reduce spot size at the focus.

Disclosed are accommodating intraocular lenses with a phase shifting lens surface profile, intraocular lenses with a mechanical accommodating structure, and methods of use thereof. For example, an intraocular lens is disclosed comprising an optic portion comprising an anterior lens and a posterior lens and an accommodating mechanical structure coupled to the optic portion. The anterior lens can comprise a phase shifting lens surface profile. The mechanical accommodating structure can comprise a plurality of compressible haptics. Each of the compressible haptics can be shaped as an annulus sector and can comprise a fluted or plicated portion configured to allow the haptics to compress or expand.

Embodiments described herein relate generally to medical implant delivery apparatuses and methods. In some embodiments, an intracameral injector needle has a substantially cylindrical body defining a longitudinal flow path therein. The body has a proximal end, a distal end, an outer peripheral face and a bevel region, with the longitudinal flow path extending from the proximal end to the distal end. A first bevel of the bevel region has a first bevel angle with respect to the outer peripheral face. A second bevel of the bevel region extends from the first bevel to the proximal end. The second bevel includes a tip of the intracameral injector needle, and has a second bevel angle with respect to the outer peripheral face, where the second bevel angle is different from the first bevel angle, the first bevel and the second bevel defining a transition therebetween. The bevel region has a tapered width. The transition is at least one of: (1) longitudinally positioned between the tip of the intracameral injector needle and a location of a maximum width of the bevel region; and (2) vertically disposed at a position below 50% of a maximum height of the bevel region.

Systems, methods, and devices for inserting an intraocular lens (IOL) into an eye may be provided. An example haptic optic management system may comprise a first cam assembly comprising a first cam body portion, an opening in the first cam body portion, and haptic folder arms disposed in the opening. The haptic optic management system may further comprise a second cam assembly positioned on one side of the first cam assembly, wherein the second cam assembly comprises a second cam body portion, an opening in the second cam body portion, and optic folders disposed in the opening. The haptic optic management system may further comprise a central plate for holding an intraocular lens in the opening of the second cam body portion, wherein the central plate is disposed between the first cam assembly and the second cam assembly.

An ophthalmic laser surgical system for treating an eye includes a laser device, one or more cameras, and a computer. The eye has anatomical features, including the cornea with the anterior corneal surface. The laser device directs a laser beam towards the eye. A camera generates images of the anatomical features, including the anterior corneal surface. The computer facilitates docking a patient interface onto the eye by accessing eye information describing the eye. The eye information comprises an eye model describing the anatomical features. The computer determines from the eye model the predicted corneal surface position when the eye is aligned to dock the patient interface onto the eye. The computer detects from the images the actual corneal surface position prior to docking the patient interface onto the eye, and compares the predicted corneal surface position with the actual corneal surface position to detect misalignment.

The present disclosure generally relates to surgical instruments for ophthalmic surgical procedures, and more specifically, surgical instruments that are capable of providing femtosecond laser pulses. In some aspects, a surgical instrument includes a body and a power amplifier disposed within the body. The power amplifier is configured to receive laser pulses from a laser source external to the body, and to deliver amplified laser pulses to an optical fiber extending toward a distal end of the body. The surgical instrument further includes an optical element disposed near the distal end. The optical element is configured to focus the amplified laser pulses.

A surgical instrument includes a tube and a horn. The tube has a distal end and a proximal end. A loop is formed with a cable that is folded between a first end of the cable and a second end of the cable. The cable is at least partially disposed in the tube. The horn is configured to oscillate. The first end of the cable is coupled to the horn. An oscillation of the horn actuates the cable.
