Let’s learn more about quality testing for eye drops.

Quality testing for user experience is essential for evaluating a medication’s effectiveness. Besides determining the correct dosage, medication developers must decide whether or not its packaging will break or leak under normal usage and if the patient or caregiver needs too much finger strength. Difficulty administering eye drops can lead to poor compliance and inadequate treatment results or disease progression. Let’s learn more about quality testing for eye drops.

Challenge of Quality Testing for Eye Drops

When quality testing for eye drops, consider the factors for the plastic bottles. Examples include the plastic’s rigidity, the nib’s length, the medication’s viscosity, and the dimensions of the bottle. Also, they are all influencers on the force necessary to administer the medication properly. Moreover, an Indian manufacturer of ophthalmic bottles wanted to determine the essential force to deliver the first drop from single-dose plastic bottles and the force to deliver subsequent drops.

Solution for Quality Testing for Eye Drops

To enhance customer experience with consumer products, a leading Indian supplier of Chatillon force gauges and material test machines, Hemetek Techno Instruments Pvt Ltd., created a squeeze force tester, mainly for testing plastic ophthalmic bottles. Using the Chatillon squeeze force tester, the manufacturer determined the finger strength necessary to squeeze various bottle designs made from different plastic materials.

To further complete quality testing for eye drops, the manufacturer performed the tests at 90 degrees to simulate the administration of the drop and at 45 degrees to affect self-administration by the patient. Additionally, the Chatillon squeeze force tester added a proprietary force test, which provides pre- and post-test analysis of test results shown as easy-to-read graphs in a Windows-based environment. As a result, results are viewed in a spreadsheet format for research. Fortunately, Bluetooth connectivity allows the wireless transfer of test results directly to the laptop, personal, or handheld computer.
