Problems solved by technology

Due to the proprietary nature of the IOL, there is a danger that the nurse and / or physician may inadvertently damage the IOL and / or incorrectly load the IOL into the syringe, resulting in implant failure
Therefore, direct manipulation and / or loading of IOLs into syringes by nurses and / or physicians is undesirable

Embodiment

[0059] Example: Testing of Syringe Devices with Surfactants

[0060] In this test, Bausch & Lomb's Akreos Adapt lens was used with a syringe of the type shown in Figures 1 and 2 . Syringe parts are made of PFA. The process is described below. The lens 30 (with optical powers ranging from +10.0d to +23.5d) is immersed in the surfactant for a few seconds and then loaded into the holder 16 which is then positioned at the distal portion within 14. The distal portion 14 with the loader 16 and the lens 30 seated therein are placed in the surfactant solution for several minutes. The proximal part 12, in which the plunger 20 is inserted, is connected to the distal part 14, and the expulsion of the lens 30 is detected. Focus on qualitatively judging the ease of expulsion by the force required. All reported surfactant concentrations are expressed as percent by weight.

Abstract

Apparatus and method for preloading an intraocular lens ( 30, 30 ') in a component of an injector device ( 10 ) and for reducing the force used to eject the intraocular lens ( 30, 30 ') therefrom are disclosed. The intraocular lens ( 30, 30 ') is positioned in a shuttle ( 16, 16 ') which is positioned inside a distal section ( 14, 14 ') of the device ( 10 ). The shuttle ( 16, 16 '), IOL ( 30, 30 '), and distal section ( 14, 14 ') are positioned and sealed in a vial ( 11 ) of solution that comprises a surfactant. At the time of use, a user opens the vial ( 11 ) and attaches a proximal section ( 12 ) having a plunger ( 20 ) to the distal section ( 14, 14 ') located in the vial ( 11 ). The proximal section ( 12 ) is then lifted away from the vial ( 11 ) together with the distal section ( 14, 14 '), and the shuttle ( 16, 16 ') and IOL ( 30, 30 ') located in the distal section ( 14, 14 '). The plunger ( 20 ) is advanced to express the IOL ( 30, 30 ') from the distal tip ( 14 c, 14 c') of the distal section ( 14, 14 ').

Description

technical field [0001] The present invention relates to ophthalmic surgical devices and methods. In particular, the present invention relates to devices and methods for inserting an intraocular lens (IOL) into an eye, wherein the IOL may be conveniently preloaded in and packaged with the syringe. Background technique [0002] An IOL is an artificial lens used to replace the natural lens of the eye when it has cataracts or other diseases. An IOL is also sometimes implanted in the eye to correct a refractive error of the eye, in which case the natural lens remains in the eye along with the implanted IOL. The IOL can be placed in either the posterior or anterior chamber of the eye. IOLs are formed in a wide variety of shapes and materials. Some common IOL styles include so-called open-loop haptic IOLs, which are tri-piece, which include an optic and two haptics connected to and extending from the optic, and monolithic, where the optic and haptic are integral and closed-loop...
