Abstract
An ophthalmic device includes a housing configured to hold an injectant chamber configured to store an injectant, a plunger disposed within the injectant chamber, and a stopper coupled to a distal portion of the plunger. The device also includes a hypodermic needle disposed at a distal end of the housing, and a sample chamber located within the housing adjacent to the distal end. The housing, hypodermic needle, and sample chamber are arranged such that when the stopper is moved to a first depth within the housing, the sample chamber is configured to receive material via the hypodermic needle. The housing, hypodermic needle, and sample chamber are also arranged such that when the stopper is moved to a second depth within the housing exceeding the first depth, the injectant chamber is configured to dispense the injectant through the hypodermic needle.
