Abstract
In accordance with various embodiments, an intraocular manipulator is disclosed which uses negative pressure to grasp and/or manipulate an intraocular object, for example, an IOL, a crystalline lens, or an intraocular foreign body. The device comprises a tip, a stem, and a suction source. The device may be a handheld device with the negative pressure controlled by a foot pedal. Similarly, the device may be used in conjunction with other intraocular devices.
Claims20
A device for grasping an intraocular object comprising:
- a tip having a proximal end and a distal opening, wherein said distal opening has a surface area of less than about 20.0 mmΛ2;
- a suction source configured to apply negative pressure of at least 40 mN without breaking a seal at said distal opening, and
- a stem comprising a flexible material and having a lumen extending there through configured to couple said proximal end with said suction source.
A method for manipulating an object intraocularly comprising:
- gaining surgical access to an intraocular object;
- contacting said intraocular object with a distal opening of an intraocular manipulator;
- applying a negative pressure to said distal opening;
- manipulating said intraocular object;
- and
- releasing a seal made at said distal opening by said negative pressure.
