Near Vision Inlays
Enjoy Life without Depending on Reading Glasses
Corneal inlays restore near vision and free you from the constant frustrations of reading glasses. Inlays are ideal for active people looking to reduce dependence on reading glasses or contact lenses for their everyday activities. The KAMRA® and RAINDROP® inlays:
- 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 clear near vision over time
How the KAMRA® Inlay Works
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. Using the pinhole effect, the inlay focuses light coming into your eye to restore your near vision. 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. 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 changes as you age.
What vision problems can Near Vision Inlays improve?
How Our Eyes Work
The eye is a tiny organ that measures about an inch long and weighs about 1/4 of an ounce. It is part of a complex system that translates light into images. Light enters our eye through the cornea and into the pupil. The pupil is the black hole in the middle of the iris, the colored part of the eye. Behind the iris is the natural lens. It focuses the light onto the retina, the inside layer of the eye. The retina contains cells that are sensitive to light. The image is then converted into electrical impulses that are sent through the optic nerve at the back of the eye to the brain.
All of this happens continuously and instantly to give us clear vision from near to far distances. But, our eyes don’t always work perfectly. Their exact size and shape affect how well they focus light. These differences can cause some of us to have refractive errors such as myopia, hyperopia or astigmatism. In addition, over time, we all lose our ability to focus on near objects. This is a refractive condition known as presbyopia.
- Presbyopia is the clinical term for near vision loss that starts affecting us in our 40s and 50s
- Over time, the eye’s natural lens becomes too stiff to focus up close
- Print and other nearby objects become blurry
- Ability to clearly see near objects, but distant objects are blurry
- Occurs when the cornea is too rounded or steep, or the eyeball is too long
- The eye’s refractive power is too strong
- Ability to clearly see distant objects, but nearby objects can be blurry
- Occurs when the cornea is too flat or the eye is too short
- The eye’s refractive power is too weak
- Light coming into the eye is focused inconsistently
- All objects are stretched or distorted
- Occurs when the cornea has an irregular oval shape
- Can occur simultaneously with nearsightedness or farsightedness
What to expect from the inlay procedure?
From start to finish, the KAMRA® inlay procedure will typically take less than 20 minutes. Numbing drops are used to ensure you are comfortable throughout the procedure. You may feel slight pressure while the doctor uses a laser to create a small opening in the first few layers of your eye, known as the cornea. However, it only lasts a few seconds. The inlay is then placed within the opening. Once the numbing drops wear off, your eyes may feel irritated or scratchy and you may also experience excessive tearing or light sensitivity. This is normal.
You will not be able to drive home following the procedure so make arrangements beforehand for a ride. You should not drive until your doctor tells you that this is okay.
How Long is the Recovery from KAMRA® Inlay Procedure?
As with any eye surgery, 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 way 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:
- Avoid using your reading glasses
- Take your medications as prescribed by your doctor, including artificial tears
- Keep your follow-up appointments with your doctor
It is typical to experience some fluctuations in your vision in the first three to six months after surgery. This is often a sign of dry eye or your brain adapting to the new vision. These will likely stabilize. The key to success are to be patient with the recovery process and diligent in following your doctor’s instructions.
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 inlay is not centered properly or if the effects are not ideal, your doctor can safely remove the KAMRA®<inlay.
