OCUTAP

Design makes a delicate procedure simpler and safe.

AC paracentesis is a delicate procedure where an ophthalmologist inserts a needle into the eye to withdraw fluid to diagnose infections or relieve dangerous pressure that causes vision loss.

The existing workflow was plagued by a human factors flaw: because the patient is positioned behind a large microscope (slit lamp), the doctor often lacks the hand-space to both steady the needle and pull the syringe plunger. This forced a second clinician to assist, increasing the risk of accidental injury during a high-stakes moment.

By prioritizing the user’s physical constraints, we transformed a risky, two-person task into a streamlined, one-handed procedure. OcuTap demonstrates our ability to simplify complex mechanical workflows into intuitive, market-ready medical devices.

In conjunction with our engineering partner, Enginuity Works, we worked with Visionaire to design this tool from the ground up, focusing on ergonomics and mechanical innovation to allow for single-handed, solo operation. Innovations include:

  • A clever internal mechanism allows the clinician to create the required vacuum before the needle enters the eye.

  • Haptic and visual cues—a clear “click” and a green indicator band—to confirm the device is primed.

  • A light button press opens the vacuum, slowly withdrawing the fluid, and giving the doctor precise control without a second assistant.
