A method implemented in an ophthalmic surgical laser system that employs a resonant scanner, scan line rotator, and XY- and Z-scanners, for forming a corneal flap in a patient's eye with improved bubble management during each step of the flap creation process. A pocket cut is formed first below bed level, followed by the bed connected to the pocket cut, then by a side cut extending from the bed to the anterior corneal surface. The pocket cut includes a pocket region located below the bed level and a ramp region connecting the pocket region to the bed. The bed is formed by a hinge cut and a first ring cut at lower laser energies, followed by a bed cut and then a second ring cut, which ensures that any location in the flap bed is cut twice to minimize tissue adhesion. The side cut is formed by multiple side-cut layers at different depths which are joined together. All cuts are formed by scanning a laser scan line generated by the resonant scanner.

Lasik flap cutting patterns including intrastromal pocket for bubble management

A method implemented in an ophthalmic surgical laser system for forming a corneal flap in a patient's eye with improved bubble management. The flap includes a horizontal bed and a vertical or near vertical side cut around the periphery of the bed except for an uncut hinge area. The side cut has a bubble barrier layer that can prevent bubbles formed by the laser-tissue interaction from escaping into an interface between the corneal and the patient interface lens. In some embodiments, the bubble barrier layer is a thin uncut layer, located in the epithelium of the cornea, that separates the side cut into two portions. In other embodiments, the side cut does not reach the anterior corneal surface, leaving an uncut bubble barrier layer located with the epithelium. In other embodiments, an additional side cut portion is formed through the uncut bubble barrier layer as the last step.

Embodiments generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for lenticular laser incision. In an embodiment, an ophthalmic surgical laser system comprises a laser delivery system for delivering a pulsed laser beam to a target in a subject's eye, an XY-scan device to deflect the pulsed laser beam, a Z-scan device to modify a depth of a focus of the pulsed laser beam, and a controller configured to form a top lenticular incision and a bottom lenticular incision of a lens in a corneal stroma.

Methods for lenticular laser incision

In laser-assisted corneal lenticule extraction procedures, the lenticule incision profile includes anterior and posterior lenticule incisions, with one or more of the following features: plano transition zone outside the optical zone, to improve mating of anterior and posterior incision surfaces after lenticule extraction; shallow arcuate incisions above the anterior incision and near the lenticule edge, to improve surface mating; separate ring cut intersecting the anterior and posterior incisions in the transition zone, to reduce tissue bridges and minimize tear at the lenticule edges and facilitate easy lenticule extraction; larger posterior incision, which includes a pocket zone outside the lenticule edge, for better surface mating and bubble management during cutting; and a separate ring shaped pocket cut intersecting the pocket zone of the posterior incision, for bubble management. An entry cut can intersect either the pocket zone of the posterior incision or an entry extension zone of the anterior incision.

Embodiments generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for lenticular laser incisions to form a top lenticular incision, a bottom lenticular incision of a lens in the subject's eye, an added shape between the top and bottom incisions where the added shape has no corrective power and a transition ring bisecting both the top and bottom lenticular incisions.

An ophthalmic surgical laser system includes: a laser that produces a pulsed laser beam having a pulse energy and pulse repetition rate; a high frequency fast scanner; an XY-scan device; a Z-scan device; and a controller. The controller controls the high frequency scanner to produce a scan line having a scan width; controls the XY-scan device and the Z-scan device to carry out of first sweep of the scan line in a first sweep direction and to carry out a second sweep of the scan line in a second sweep direction that is not parallel to the first sweep direction thereby defining an overlap region. At least one of the pulse energy, repetition rate, XY-scan speed, and the scan width is varied so as to accelerate the cutting speed and reduce the exposure of ophthalmic tissue in the overlap region to multiple exposures of laser pulses configured to modify ophthalmic tissue.

Lenticular laser incision for low myopia and/or hyperopia patients

An ophthalmic laser procedure for forming a lenticule in a cornea and extracting the lenticule from the cornea to accomplish vision correction. An ophthalmic laser system is used to form top and bottom lenticule incisions defining a lenticule in between, and further to form top and/or bottom entry cuts that respectively end unambiguously near the top or bottom lenticule surface. The bottom entry cut intersects both the top and bottom lenticule incisions but ends near the bottom lenticule incision. The entry cuts allow the surgeon to insert a surgical tool which reaches the intended top or bottom lenticule surface without ambiguity. The lenticule has an optical zone in the center that defines the optical power of the lenticule, and a transition zone in the periphery, where the end points of the entry cuts are located in the transition zone.

An easily assembled and disassembled portable golf swing training device includes plural interconnected elongated, linear rods and arms for the development of proper golf club takeaway, backswing and downswing mechanics. The position of the golf club during the swing is compared with generally accepted swing parameters, and club positions not within acceptable limits are evidenced by easily detected golf club contact with one or more of the device's arms which are all adjustable in length and position depending upon individual golfer characteristics, and which are pivotally mounted, padded and flexible to avoid injury as well as damage to the inventive device or to a golf club. The configuration of the various rods and arms is established to provide the golfer an inside-to-out club head path during the downswing to provide for a draw of the ball, or to shape the shot from right to left for a right hand golfer.
