Common KAMRA Inlay FAQs
Q: What is the KAMRA™ corneal inlay?
A: The KAMRA™ inlay is a safe, proven and lasting solution to correct presbyopia and restore your every day near vision. Smaller and thinner than a contact lens, and lighter than a grain of salt, the inlay is an opaque ring with an opening in the center.
Q: How does the KAMRA™ inlay work?
A: It works on the same principle as a small camera aperture by increasing the depth of focus. The opening in the inlay allows only focused light into the eye, allowing you to see near, far and everything in-between.
Q: Who can benefit from the KAMRA™ inlay?
A: The KAMRA™ inlay may be ideal for any individuals over 40 seeking a solution to restore their every day near vision and reduce their dependence on glasses or contact lenses.
Q: What benefits does the KAMRA™ inlay provide?
A: By its definition, the KAMRA™ inlay: “Provides freedom to enjoy everyday activities without glasses. Restores clarity at near and intermediate (computer) vision. Maintains distance vision.”
In our words, it means that you can see the things up close that you couldn’t before – menus, text messages, computers, newspapers – and still see clear at distance.
Q: Will my distance vision change?
A: Unlike monovision with LASIK or contact lenses that can significantly compromise your distance vision, KAMRA™ corneal inlays are a supplement that restores near and intermediate vision, while maintaining distance vision.
Q: If it doesn’t affect my distance vision, then why is it put in only one eye?
A: You naturally have one dominant eye for seeing things far and a non-dominant eye for vision up close. The KAMRA™ inlay is only placed in your eye used for reading vision, allowing you to see up close clearly. Your other eye is either left untouched or is corrected for great distance vision. Working together, the eyes allow you to see near, far and everything in-between.
Q: How long will my KAMRA™ Vision last? Do I need to replace the inlay if my presbyopia worsens?
A: KAMRA™ Vision is the lasting solution to presbyopia. Assuming your eyes don’t change, your vision with the KAMRA™ inlay will go unchanged. However, if you develop cataracts or changes in your underlying prescription, you may need an alternative treatment for those issues. (i.e. laser vision correction or cataract surgery).
The KAMRA™ Corneal Inlay Technology
Q: What material is the KAMRA™ inlay made of?
A: The KAMRA™ inlay is comprised of a proven biocompatible material frequently used in a wide variety of eye and other medical implants, called polyvinylidene fluoride. In addition, the inlay has been tested and implanted safely in thousands of eyes.
Q: How big is the KAMRA™ inlay?
A: It is much smaller and thinner than a normal contact lens. The inlay is 3.8mm in diameter with a 1.6mm opening in the center. It is 5 microns thick (or the thickness of a red blood cell and one-tenth the thickness of a sheet of paper). It weighs less than a grain of salt.
Q: Will I feel the inlay in my eye?
A: The KAMRA™ inlay is placed underneath the eye in the first few layers of the cornea so it is not felt. There have been no documented reports of anyone feeling the inlay in their eye.
Q: Will people be able to see the inlay in my eye?
A: The KAMRA™ inlay is rarely noticeable – how noticeable depends on the size of your pupil, the color of your eye, and the lighting conditions. For people with larger pupils and darker eye color (e.g., brown), the inlay is virtually invisible. For individuals with lighter colored eyes (e.g., blue), the inlay is rarely noticed unless someone knows to look for it and are very close. It may be easier to see from the side in very bright light.
Q: Will the KAMRA™ inlay darken my vision?
A: The inlay is designed to help your eye focus the light so images and text look clear again. Right after the inlay is implanted, you may notice some darkening, but as your eyes adjust and you heal, there will be little to no dimness noticed.
Q: Will the inlay decrease my peripheral vision?
A: The KAMRA™ inlay does not affect your peripheral (side) vision.
Q: Does the inlay move in my eye?
A: The inlay does not move; once it is placed in the eye it instantly adheres to the corneal tissue. Additionally, there are over 8400 laser-etched openings in the inlay, designed for maximum breathability and health to the cornea.
Q: How many people have had the KAMRA™ inlay?
A: KAMRA™ inlays have been around for more than a decade in investigational and commercial use. Thousands of patients, including eye doctors, have chosen the KAMRA™ inlay as their preferred near vision treatment.
Q: Can the inlay be removed?
A: The KAMRA™ inlay has been proven to be a safe and effective solution for reducing the need for reading glasses. However, if for some reason you are unsatisfied with your vision after treatment, it can be removed and your vision restored to its pre-KAMRA state.

The KAMRA™ Procedure
Q: What can I expect during the surgery?
A: From start to finish, the surgery usually takes less than 20 minutes, and is very similar to LASIK. Your eyes are numbed with drops, and we’ll talk you through every second of it. It will be done before you know it!
Q: How is the KAMRA™ inlay placed in the eye?
A: Using a femtosecond laser, a small pocket is made just beneath the surface of your eye in the cornea. Your surgeon will then place the inlay in the pocket, centered with your line-of-sight. The tissue of your cornea is amazingly resilient – it bonds within 24 hours and heals quickly, securing the inlay in place.
Q: What are the potential complications/side effects after the KAMRA™ procedure?
A: Side effects are minimal, but when they do occur, they are much like LASIK – dry eye, glare, haloes…etc. Over time, these conditions are expected to resolve. We will thoroughly discuss potential side effects with you before surgery.
Q: Does the procedure hurt?
A: As with LASIK, you’ll feel slight pressure from the laser during the creation of the flap, but you should experience no pain and little discomfort.
After the KAMRA™ procedure
Q: When can I expect to see improvement in my near vision?
A: Most patients experience improvement within the first 24-48 hours. However, optimal results are usually achieved between one and three months postoperatively. Visual recovery depends on personal healing patterns and compliance with your doctor’s post-operative instructions (follow up visits, medications).
Q: How much will my near vision improve?
A: The amount of near vision improvement varies by individual. On average, patients are able to read fine print such as medicine labels. While your use of reading glasses will decrease, you may find at times you are more comfortable with reading glasses for the extremely small print, in dim lighting conditions or for extended periods of reading.
Q: How soon after the surgery can I resume normal activities?
A: Almost immediately. Most patients resume normal activities and return to work within the first few days.
Q: Will I ever need to wear reading glasses again?
A: The KAMRA inlay is ideal for individuals who want to be able to do everyday activities without reading glasses. If the idea of being able to go shopping, dine out with friends, read a text message or check the time on your watch without glasses is appealing to you, the KAMRA inlay is a good option for your lifestyle.
Q: Can you assure me I will not need reading glasses?
A: While many patients do achieve spectacle independence, that is not the absolute goal. You may need reading glasses if you are working in dim light, performing a near task for a prolonged period of time, or attempting to read the tiny print. Also, when your eyes are tired or “dry”, you may choose to wear reading glasses.
Q: How can I achieve the best results?
A: The most important activity you can do to ensure your result is to adhere to your post-op instructions. Furthermore, you can accelerate your visual recovery by regularly performing reading exercises and not using reading glasses when performing near tasks. For more information, you may download our KAMRA™ patient recovery guide here.
Q: Is it normal to experience blurry vision or fluctuations?
A: Yes, it is common to experience these symptoms on and off during the first few months. This is often a sign of dry eye or your brain adapting to the new vision. Using your eye drops and giving your eyes frequent breaks can improve these conditions.
Q: What if I already had eye surgery?
A: Even if you had prior eye surgery, you may still be a candidate for a KAMRA™ corneal inlay. We can tell you at your complimentary consultation.
Q: What will happen if I develop cataracts?
A: Should you develop a cataract, you can still have it easily removed and replaced with cataract surgery. Your inlay will continue to provide excellent near and intermediate vision. It’s important to note that the inlay shouldn’t increase any risks associated with having cataract surgery.
Q: Will there be better and newer treatment available in the near future?
A: There are always possibilities of advancements in the medical field; however, this is the most promising near vision technology in over a decade. An additional benefit of the KAMRA™ inlay is that it can be used in conjunction with other treatments, or it can be removed, allowing patients the option to take advantage of future technology development.
Q: Am I a suitable candidate for KAMRA™ inlays if I have allergies or dry eye?
A: Yes, you may still be an excellent candidate for KAMRA™ Vision. To determine if you’re eligible, your eyes will need to be assessed during your free consultation, where we will test the dryness of your eyes. If required, we can prescribe and treat any underlying allergy/dry eye issues to prepare you for the KAMRA™ inlay.
Q: I wear bifocals; can I still have the surgery?
A: Yes. In fact, in the case of bifocal wearers, the KAMRA™ inlay procedure can be performed in conjunction with LASIK, reducing your need for glasses at all distances.
