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. |
