Abstract

The present invention is a method of operating an ophthalmic hand piece. A connection between a tip segment and a limited reuse assembly is recognized. A type of tip segment connected to the limited reuse assembly is determined. Dosage information is received. A first input is received. In response to the first input, a heater is activated to heat a substance contained in a dispensing chamber. After the substance has reached a desired temperature range, the dosage information is used to control a distance a plunger travels. A second input is received. In response to the second input a motor is activated, and the drug is delivered into the eye.

Description

technical field [0001] The present invention relates to devices for injecting drugs into the eye, and more particularly to a two-piece ophthalmic drug delivery device with a disposable tip. Background technique [0002] Several diseases and conditions of the back segment of the eye endanger vision. Age-related macular degeneration (ARMD), choroidal neovascularization (CNV), retinopathy (eg, diabetic retinopathy, vitreoretinal disease), retinitis (eg, cytomegalovirus (CMV) retinitis), uveitis, macular edema , glaucoma and neuropathy are a few examples. [0003] These and other conditions can be treated by injecting drugs into the eye. Such injections are typically performed manually using conventional syringes and needles. Fig. 1 is a perspective view of a prior art syringe for injecting a drug into an eye. In FIG. 1 , the syringe includes a needle 105 , a luer hub 110 , a chamber 115 , a plunger 120 , a plunger rod 125 , and a thumb rest 130 . The drug to be injected is...
