A Comparison of Conventional Intravitreal Injection Method vs InVitria Intravitreal Injection Method.

Area of Science:

• Ophthalmology
• Medical Device Technology
• Patient Safety

Background:

• Intravitreal injections are a common procedure in ophthalmology.
• Traditional intravitreal injection methods can cause patient discomfort and are time-consuming.
• There is a need for improved devices to enhance patient experience and procedural efficiency.

Purpose of the Study:

• To compare patient comfort, injection speed, and cost-effectiveness of the InVitria device versus the conventional intravitreal injection method.
• To evaluate the impact of the InVitria device on patient-reported pain scores.
• To assess the time efficiency and economic benefits of using the InVitria device.

Main Methods:

• A prospective study involving 58 patients undergoing intravitreal injections.
• Patients used visual analogue scales (VAS) to score pain associated with both conventional and InVitria methods.
• Procedure duration was timed, and cost analysis was performed for both techniques.

Main Results:

• The InVitria device demonstrated statistically significant reductions in patient-reported pain scores across most aspects of the intravitreal injection procedure compared to the conventional method.
• The InVitria device was, on average, 1 minute and 32 seconds faster per injection.
• Implementing the InVitria device resulted in an estimated annual cost saving of £24,300 for the healthcare trust.

Conclusions:

• The InVitria intravitreal injection device positively impacts patient comfort, reduces procedure time, and offers significant cost-effectiveness.
• The adoption of the InVitria device at the Newcastle Eye Centre has led to measurable improvements in patient care and operational efficiency.
• The InVitria device represents a valuable advancement in the administration of intravitreal injections.
