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.
