KAMRA Reading Procedure

New: KAMRA Corneal Inlay for Reading Vision

The KAMRA corneal Inlay is a new procedure to help reduce the need for reading glasses. Dr. Peter Hersh was a principal investigator and the CLEI team participated in the clinical trials leading to the recent FDA approval. You can watch a video interview with one of our Corneal Inlay clincial trial patients here – http://www.vision-institute.com/new-jersey/video.htm.

It is ideal for active people looking to no longer depend on reading glasses for mid-distance and reading tasks, problems which occur in everyone as they enter middle age. The KAMRA inlay:

  • Restores everyday vision so you can see text messages, a computer screen and the time on your wrist watch, without the frustration of reading glasses
  • Provides a natural range of vision – from near to far – without blurry zones
  • Offers a long-term solution that will help you enjoy clearer near vision over time KAMRA Inlay vs. Contact Lens

Smaller than a contact lens, the KAMRA corneal inlay looks like a black ring. There is a tiny aperture or hole in the center of the inlay. The inlay may help to improve vision in two ways

  1. Creates a pinhole effect so near objects are clearer.
  2. Focuses light rays so you can see a wider range of vision near, intermediate (computer) and distance.

Why is My Near Vision Changing?

In our 40s and 50s, we begin to experience the naturally frustrating effects of blurry near vision. Reading the newspaper, seeing the computer screen or sending a text message becomes a stuggle. We end up depending more and more on reading glasses or contact lenses to see up close. This natural loss of reading vision is called presbyopia (prez-bee-OH-pee-ah), and eventually affects all of us, even if we never needed vision correction before.

What Causes Presbyopia?

The eye’s natural lens is normally elastic and flexible. It works like a camera lens to automatically adjust and focus our vision. This lets us automatically switch our gaze from something near to something far away. Over time, the lens in your eye begins to stiffen. It can’t bend into the right shapes to bring close objects into clear focus. To compensate, you end up moving objects further away to help your eye to focus.

Presbyopia continues to progress over time. For example, someone who is 45 may only notice it when trying to read tiny print in low light. However, someone who is 50 will start to need reading glasses throughout the day.

Before KAMRA

BEFORE: When the natural focusing ability of the eye diminishes, near vision becomes blurry


AFTER: With the KAMRA inlay, unfocused light is blocked, making near vision clear

How does the KAMRA Inlay Work?

The KAMRA inlay sits in the first few layers of the eye known as the cornea. Smaller and thinner than a contact lens, the inlay is a mini-ring with an opening – or pinhole – in the center. This pinhole allows only focused light to enter your eye. The KAMRA inlay is placed in only one of your eyes, allowing you to see up close, while maintaining your distance vision in both eyes. Your non-KAMRA eye is left untouched. Working together, the eyes allow you to see near to far. This is unlike monovision laser vision correction, which corrects one eye for near and one eye for distance and does not last over time.

What can I expect during the KAMRA procedure?

During an out-patient procedure performed at The Cornea and Laser Eye Institute, Dr. Hersh, will implant the inlay in one eye. From start to finish, the KAMRA inlay procedure will typically take around 30 minutes. Numbing drops are used to ensure you are comfortable throughout the procedure. You may feel slight pressure while Dr. Hersh uses a laser to create a small opening the first few layers of your eye, known as the cornea. This is the same type of laser that is used to start a LASIK procedure. The inlay is placed within the opening created by the laser. Once the numbing drops wear off, your eyes may feel irritated or scratchy and you may also experience tearing or light sensitivity. Dr. Hersh and staff will provide instructions on post-operative care the day of treatment, including eye drops to use afterwards. You will not be able to drive home after your procedure, so arrangements should be made beforehand for a ride. You should not drive until Dr. Hersh tells you that this is okay.

What is the recovery process?

As with any eye procedure, healing is a process. Adhering to your doctor’s recovery instructions will accelerate your progress. It is important to remember that the amount and pace of near vision improvement varies by individual. While some patients see an improvement within the first week to a month, others may require additional time to heal. Most patients resume normal activities and return to work within 24-48 hours.

To enhance your recovery and near vision improvement, you should:

  1. Avoid using your reading glasses
  2. Take your medication as prescribed by Dr. Hersh, including artificial tears
  3. Keep your follow-up appointments with the office

Keep in mind that some KAMRA patients may still require reading glasses for activities such as reading tiny print or reading in low light. In addition, if the effects of the inlay are not ideal, the KAMRA inlay can be safely removed. For instance, some patients can notice the dimming of night vision in the implanted eye or may not achieve the desired reading vision effect.
