Frequently asked questions

Frequently asked questions


How does the lens stay in place?

The Lens sits on the Tympanic Membrane, similar to the way a contact lens sits on an eye –– through surface tension. When placed, the ENT physician places a small drop of mineral oil on the Tympanic Membrane to help create this surface tension. Weekly, the user applies mineral oil to the ear to maintain this surface tension.

How long does the lens stay in place?

Studies show that the Tympanic Lens stays in place for long periods of time. We recommend that the ENT Physician evaluate the Lens as part of an annual check-up, and determine if the Lens needs to be replaced.

Is the Lens safe?

Clinical studies show that the Tympanic Lens does not damage the Tympanic Membrane or ear canal. In our Feasibility and Definitive trials, investigators saw no change in hearing thresholds after 120 days of use (p<0.0001). Learn more in our clinical data section.

Is this an implant?

The Tympanic Lens isn’t an implant, as it is simply placed in the ear and can be removed at any time by an Ear, Nose and Throat Physician.

Can patients swim, shower etc?

Yes, users can shower or swim as they normally would with the Tympanic Lens in place. We recommend the patient apply a little mineral oil to the ear after swimming. Strong direct stream of water to the ear should be avoided. If the user regularly has their head immersed in water for long periods of time, we recommend a set of ear plugs to help ensure the Tympanic Lens is properly protected.

Can patients get an MRI with the Lens in place?

Users should have the Lens removed for an MRI and then replaced once the MRI is complete.


Is Anesthesia required?

Neither the impression process or Lens placement/removal require anesthesia.

How long does it take to place or remove the lens?

Placing or removing a Tympanic Lens is a short procedure. It takes about 15 minutes and is performed in the doctor’s office without anesthesia. Most people report mild or no discomfort.

Does the placed Lens cause hearing to be dampened?

Our studies have shown that the Tympanic Lens can be associated with <5 dB of damping (loss) across the spectrum peaking at 1kHz. This “damping” is reported to be perceived some patients when they are not wearing the processor and eartip.

How long does it take to program an Earlens Hearing Aid?

Programming or fitting the Earlens Hearing Aid via our NOAH compatible software is very similar to fitting a traditional hearing aid. We recommend reserving the same amount of time that you would for a Hearing Aid Fitting Appointment.

Can ambient light activate the lens?

The light pattern and frequency used by the Earlens Hearing Aid is very specific. When a microscope light is focused in the ear, patients have reported hearing a light hum. In our clinical studies, no patients reported hearing from outside light sources when using the Earlens Hearing Aid. Learn more in our clinical data section.


What are the benefits of high frequency hearing?

Research suggests that high frequencies are extremely important for enhanced sound quality and hearing in noisy situations. See more in our clinical section. The Earlens Hearing Aid is the first to deliver true high frequency audibility to people with hearing loss, and we anticipate additional studies to come.

How much does the Earlens hearing aid cost?

The price of Earlens is set by the Earlens provider and will depend on your type and level of hearing loss. Make an appointment with your local Earlens provider to learn more.

Is high frequency amplification tolerable?

Some patients may need to ease into their prescribed high frequency gain with the Earlens acclimatization program. Others tolerate their prescribed high frequency gain immediately.
