Abstract
In various embodiments, an ophthalmic injection device may include a dispensing chamber, a first thermal sensor coupled to the dispensing chamber, a temperature control layer coupled to the dispensing chamber, a second thermal sensor coupled to the dispensing chamber, and a first processing device. The first processing device may be configured to receive temperature information from the first thermal sensor and the second thermal sensor and control the temperature control layer using the received temperature information. In some embodiments, the first processing device may receive temperature information directly from the second thermal sensor (e.g., in analog form) and may compare the temperature information from the first thermal sensor (e.g., received from the second processing device in digital form) and the second thermal sensor to detect temperature offsets between the two sensors.
