Method and Apparatus for Creating Ocular Surgical and Relaxing Incisions
A system and method of treating target tissue in a patient's eye, which includes generating a light beam, deflecting the light beam using a scanner to form first and second treatment patterns, delivering the first treatment pattern to the target tissue to form an incision that provides access to an eye chamber of the patient's eye, and delivering the second treatment pattern to the target tissue to form a relaxation incision along or near limbus tissue or along corneal tissue anterior to the limbus tissue of the patient's eye to reduce astigmatism thereof.
Systems and methods for reducing spherical aberration using periphery modification
A system for determining a vision treatment for an eye of a patient is provided which includes a memory and a processor, in communication with the memory, configured to receive a first treatment target corresponding to a first target shape of a surface of the eye, obtain a periphery modification function (PMF), determine a second treatment target corresponding to a second target shape of the surface of the eye by multiplying, for each of a plurality of points on the surface of the eye, the PMF by the first treatment target, and scale the second treatment target using a scaling factor such that values of the second treatment target are scaled to be greater at a mid-periphery of the eye and scaled to be lower at a far-periphery of the eye. A treatment parameter of a treatment applied to the surface of the eye is controlled by the scaled second treatment target.
Tissue-Augmented Corneal Inlay Surgery Technique
A tissue-augmented corneal inlay surgery technique is disclosed herein. In one embodiment, the surgery method includes the steps of: (i) implanting a corneal inlay into a recipient cornea of an eye of a patient; (ii) applying laser energy to a central portion of the corneal inlay and a portion of stromal tissue of the recipient cornea underneath the corneal inlay so as to modify the refractive power of the eye; (iii) applying a cross-linking solution that includes a photosensitizer to the recipient cornea of the eye of the patient; and (iv) irradiating the corneal inlay and surrounding corneal tissue so as to activate cross-linkers in the corneal inlay and the surrounding corneal tissue. In this embodiment, the central portion of the corneal inlay remains clear for the patient without being obstructed by swollen tissue so that the patient is able to see immediately after the corneal inlay surgery.
Method and apparatus for creating ocular surgical and relaxing incisions
A system and method of treating target tissue in a patient's eye, which includes generating a light beam, deflecting the light beam using a scanner to form first and second treatment patterns, delivering the first treatment pattern to the target tissue to form an incision that provides access to an eye chamber of the patient's eye, and delivering the second treatment pattern to the target tissue to form a relaxation incision along or near limbus tissue or along corneal tissue anterior to the limbus tissue of the patient's eye to reduce astigmatism thereof.
Corneal implant systems and methods
A system for forming a corneal implant includes a cutting apparatus, which includes a laser source that emits a laser and optical elements that direct the laser. The system includes a controller implemented with at least one processor and at least one data storage device. The controller generates a sculpting plan for modifying a first shape of a lenticule formed from corneal tissue and achieving a second shape for the lenticule to produce a corneal implant with a refractive profile to reshape a recipient eye. The sculpting plan is determined from measurements relating to the lenticule having the first shape and information relating to a refractive profile for a corneal implant. The controller controls the cutting apparatus to direct, via the one or more optical elements, the laser from the laser source to sculpt the lenticule according to the sculpting plan to produce the corneal implant with the refractive profile.

Refractive treatment of an eye by printing material onto a target
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.
Laser eye surgery system
An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.
