    摘要： Featured are new methods for performing intra-ocular surgery that allow surgical personnel to access the intra-ocular volume to perform a surgical procedure or technique but which does not require the use of sutures to seal the sclera and/or conjunctiva following the procedure. The methods of the present invention generally include providing an entry alignment device and inserting the entry alignment device into an eye through both the conjunctiva and sclera so as to form an entry aperture that extends between the exterior of the eye and the intra-ocular volume within the eye. The provided alignment device is configured so as to form or provide an aperture or opening in each of the conjunctiva and sclera of the eye and to maintain these apertures or openings in each of the conjunctiva and sclera aligned during the surgical procedure so these apertures or openings form the entry aperture. In more particular aspects, the provided entry alignment device is sized such that when the entry alignment device is removed from the eye following the completion of the surgical procedure, the aperture or opening formed in the sclera seals without the use of sutures. In a more specific aspect of the present invention, the provided entry alignment device is sized such that the apertures or openings and thus the entry aperture are self sealing. In other embodiments, a plurality of entry alignment devices are provided so a plurality of entry apertures can be formed in the eye. The invention also features a high speed vitreous cutting and aspirating device particularly configured for use in such methods and surgical procedures and techniques as well as the related entry alignment devices and other surgical instruments.

    摘要： In preferred aspects, the present invention features a non-traumatic cannula for use in connection with eye surgery, such as retinal tear and/or detachment surgery. The non-traumatic cannula of the present invention is particularly configured so as to minimize or avoid the potential for damage to the retina when infusing air or a gas therein. Related methods are also disclosed for infusing air during eye surgical procedures e.g. for treating a retinal tear or detachment and macular hole surgery. The method for infusing a fluid, such as a gas, into a patient's eye during eye surgery includes flowing the fluid from a fluid source to the patient's eye and diffusing the flowing fluid as it enters into the patient eye. Such a method further includes providing a non-traumatic cannula that is fluidly coupled to the fluid source, and which diffuses fluid exiting an end thereof. Thus, the fluid flowing out of the cannula is thereby diffusively infused.

    摘要： Featured is a device that provides a mechanism for imaging structure and/or tissue of a surgical site during and after performing a microsurgical procedure such as ophthalmic surgical procedures. Also featured are methods and systems related thereto. In the imaging method of the present invention using such a device includes positioning a high frequency ultrasonic signal transmitting and receiving apparatus imaging mechanism in close proximity to the area to be scanned/imaged (e.g., surgical site), so that the high frequency ultrasonic signal penetrates the tissue/structure of the surgical site being scanned. The reflected ultrasonic signals, are processed so as to yield high quality/high resolution images of the scanned tissue/structure. Further, the high resolution images are evaluated by the surgeon during the procedure to determine if the surgical approach should be adjusted. If such a determination is made, then the planned surgical approach is adjusted to accommodate for any conditions not accounted for in the initial planning.
