Patent number: 8343106Abstract: In various embodiments, a trocar cannula may be configured for insertion into an eye to facilitate insertion and removal of instruments during surgery. The cannula may be affixed to an overcap (to inhibit rotation of the overcap relative to the cannula) that includes a seal. In some embodiments, the seal may be overmolded into the overcap or may include a wafer that is fixed between the cannula and the overcap to inhibit rotation relative to the cannula and the overcap. In some embodiments, the cannula and overcap may snap together through a tab/slot interface in a permanent fashion such that the cannula and overcap may not be separated without damaging the cannula or overcap. In some embodiments, a vent cannula may be receivable in the slit of the seal for allowing fluids to vent from the eye through the cannula (which may include an indentation to frictionally engage the vent).Type: GrantFiled: November 22, 2010Date of Patent: January 1, 2013Assignee: Alcon Research, Ltd.Inventors: Jose Luis Lopez, Michael M.

Patent number: 8323630Abstract: The present invention is directed to the provision of multi-dose, self-preserved ophthalmic compositions. The compositions possess sufficient antimicrobial activity to satisfy USP preservative efficacy requirements, as well as similar preservative standards (e.g., EP and JP), without requiring the presence of conventional anti-microbial preservative agents, such as benzalkonium chloride. The compositions are effectively preserved by a balanced ionic buffer system containing zinc ions at a concentration of 0.04 to 0.9 mM, preferably 0.04 to 0.4 mM. One aspect of the balanced buffer system is limitation of the amount of buffering anions present to a concentration of 15 mM or less, preferably 5 mM or less. In a preferred embodiment, the compositions also contain borate or, most preferably, one or more borate/polyol complexes. The use of propylene glycol as the polyol in such complexes is strongly preferred.Type: GrantFiled: April 14, 2011Date of Patent: December 4, 2012Assignee: Alcon Research, Ltd.Inventors: Bhagwati P.

Patent number: 8308736Abstract: An intraocular lens injection device comprises a tubular housing with a plunger longitudinally disposed within the tubular housing. An electric drive system longitudinally translates the plunger so that its tip engages an insertion cartridge to fold and displace an intraocular lens disposed within and to inject the folded lens into the lens capsule of an eye. A control circuit is configured to start translation of the plunger, responsive to user input, to detect at least one fault condition based on a counter-electromotive force produced by the electric motor, and to stop translation of the plunger assembly responsive to the detected fault condition, which may comprise excessive resistance to forward or rearward translation of the plunger or insufficient resistance to forward translation of the plunger.Type: GrantFiled: October 13, 2008Date of Patent: November 13, 2012Assignee: Alcon Research, Ltd.Inventors: Mikhail Boukhny, Bill Chen, James Chon

Patent number: 8308799Abstract: An intraocular lens (IOL) injection device is modularized to enable cleaning of internal components after surgery. The device includes first and second housing modules. These modules collectively define a passageway along which an injector rod moves between a retracted position and an extended position. The first module is further configured to accommodate a lens cartridge module. The cartridge module has disposed therein an IOL, in alignment with the passageway. Thus as the rod moves from the retracted position to the extended position, a front portion of the rod that is substantially surrounded by the first module in the retracted position moves into the cartridge module and displaces the IOL. This causes the front portion of the rod to accumulate on it viscoelastic substances. The first module, though, is configured to detach from the second module, to thereby expose the front portion of the rod in the retracted position for cleaning.Type: GrantFiled: April 20, 2010Date of Patent: November 13, 2012Assignee: Alcon Research, Ltd.Inventors: Bill Chen, James Y. Chon

Patent number: 8292434Abstract: An ophthalmic endoilluminator is provided. The ophthalmic endoilluminator includes one or more white light emitting diodes (LEDs), an additional light source, a first optical assembly, an optical coupling element, and an optical fiber optically coupled to the optical coupling element. The white LED is capped with a phosphor layer. The additional light source illuminates at least a portion of an exterior surface of the phosphor layer within an absorption band of phosphor material of the phosphor layer in order to excite the phosphor layer and produce additional white light. The first optical assembly receives and substantially collimates the white light. The optical coupling element receives the substantially collimated white light from the first optical assembly and directs the light to an optical fiber. The optical fiber is then used to conduct the white light into an eye.Type: GrantFiled: July 28, 2010Date of Patent: October 23, 2012Assignee: Alcon Research, Ltd.Inventors: Christopher Horvath, Michael J.

Patent number: 8287486Abstract: An infusion pressure monitoring system for a phacoemulsification or vitrectomy machine to be operated by a health care provider includes an irrigation path configured to carry an irrigation solution to a surgical site and a fluid sensor configured to detect a fluid parameter in the irrigation path. An input device receives a variable fluid flow command from the health care provider commanding an irrigation fluid flow through the irrigation path at a flow rate corresponding to the command. A controller communicates with both the fluid sensor and the input device. The controller determines an expected fluid pressure value and a dynamically variable threshold pressure value based upon the variable fluid flow command.Type: GrantFiled: May 25, 2010Date of Patent: October 16, 2012Assignee: Alcon Research, Ltd.Inventor: Valentine P.
