What is EyePrint prosthetic?

Eyeprint Prosthetic is a custom service that provides contact lenses special designed to fit each unique eye. The lens is similar to that of a scleral contact lens in that it also rests on the white part of the eye (the sclera). This provides similar benefits of a scleral lens, including oxygen permeable material that ensures optimum eye health, clear vision, and high levels of comfort. The service uses scans and impressions of the surface of the eye in order to create a lens that directly matches the shape of each person’s eye.This is a service that is only offered at our office in the entire state of Nevada! Practitioners must be certified to fit and manage the EyePrint Prosthetic. Lucky for you, Dr. Stephanie Woo is one of few practitioners in the United States that is trained to fit patients with this lens. The personalized nature of the service allows for higher quality vision, improved comfort, and greater lens stability on the eye. The Eyeprint Prosthetic provides great quality of life through improved vision for patients who are extremely visually impaired. This utilizes the latest technology to provide an alternative to corneal diseases and irregularities than cannot be improved with the use of traditional lenses.

How does the process work?

The EyePrint process involves first obtaining a mold of the front surface of the eye, similar to getting a dental mold for braces. The entire process is safe and painless. The material used to create the mold is entirely FDA approved. It takes only 80 seconds to get the information we need. The mold is then sent to a laboratory where a scanner carefully evaluates millions of points on the front of the eye to capture all irregularities and curves. This allows a state of the art laboratory to manufacture a prosthetic lens that is unique to the shape of your eye. The mold provides a unique identification of your cornea (front surface of your eye) that is as different from the next person as a finger print! No guesswork is involved and precision is utilized instead. Once the lens is completed, the lens is shipped to the doctor that fits you. Your certified eye doctor will then ensure the lens fits you and is the best option for your eye health and vision!

What is the average cost?

The EyePrint Prosthetic requires advanced training and understanding of the eye surface in order to fit the patient. Fitting a patient in these lenses is a complex process that requires a unique skill set. It also involves custom development of lenses made unique for each eye. Therefore, these lenses tend to cost more than prefabricated lenses. However, due to the many benefits of superior vision, comfort, and fit, many patients find that the benefits far outweigh the costs. The lenses and fitting may be covered by insurance. Check with your insurance and eye doctor in order to determine if this is the right fit for you.

Frequently asked questions about EyePrint Prosthetic

Can any doctor fit the EyePrint Prosthetic? No. To be an EyePrint Practitioner, you must become certified in the technology. Doctors may fly to the lab in Colorado for a day long training or have a lab representative come to the office to train the doctor. During this training, practitioners learn about the EyePrint technology, the design process, the fabrication process, and must practice the impression process several times. It is important to become proficient in taking an impression, because that is the data that is used to design the custom device. The impression must be well centered and usable for the laboratory.

How can I find a doctor who is certified in the EyePrint technology? is a website where you can find all of the practioners certified in this technology.

Why don’t more doctors offer the EyePrint PRO? Unless a doctor is seeing many patients who need specialty contact lenses, it would not make sense financially to include this into their practice. If a doctor only has 1 or 2 patients a year who might need this technology, it is best if they refer that patient to another provider. The EyePrint team also selects the doctors who are eligible for the EyePrint technology. Practitioners are only eligible if they demonstrate proficiency in specialty contact lenses, and treat a large number of patients.

Do I need to do anything special before I arrive for my EyePrint fitting? YES! Please make sure you are out of any contact lenses for at least 48 hours. This ensures that your eye goes back to its original shape so that the impression of your eye is super accurate. Please make sure not to wear any contact lenses at least 48 hours prior to your appointment.

What is the process like? When you arrive to your eye doctor, you will sit in the exam chair, just like any normal eye exam. Then, the doctor will review the process with you and find out if you have any questions. First, the impression material is mixed together in a special tube and then inserted into a small tray. Then, the material sets up in the tray for about 40 seconds. Then, the doctor will insert the tray under your upper and lower lids and let go. The tray will sit on your eye for about 90 seconds and then the doctor removes the tray. The result is a perfect impression of your eye.

Does the impression process hurt? For most patients, the impression process is not painful. Most patients exhibit a “funny gooey feeling.” The eyelids are also stretched a bit when the impression is in the eye, so some people feel like their eyelid is stretch-y.

How many impressions will the doctor take? It depends. The impression has to be near perfect for the laboratory to use the data. If the impression does not look perfect, the doctor will have to repeat the impression.

What happens after the impression? If you are getting an EyePrint for vision correction, the doctor may place a diagnostic scleral lens on your eye to determine what prescription to add into your EyePrint.

What happens when I leave the office? The impressions will be sent to the laboratory by mail. Then, the EyePrint team will use a 3D scanner to scan the impression and design a lens based on your specific eye condition. What’s great about the EyePrint is that we have full customization. We design the lens to be shaped in any way we desire. Once the EyePrint lens is designed, it will go in the queue for fabrication. The information from the scanner is sent to the lathe, which will cut the lens and shape the lens using special software. Then, the device is shipped back to the doctor’s office.

How long will it take to get my EyePrint? Most devices are designed, fabricated, and shipped back to us within 4 weeks.

I want my EyePrint device faster, is that possible? Yes, there is an expedited option to overnight ship the impressions and the lab puts your order ahead of everyone else’s for an additional cost. Most patients will have their lens within 3-5 days.

Why is the EyePrint more expensive than a scleral lens? The time spent designing your unique device and the cost involved to create something so custom is a very time consuming and tedious process. Multiple people are involved when designing your EyePrint, and the technology used is unlike any other lens. This is why the lens costs so much more than a traditional scleral lens.

What happens if my EyePrint breaks? If the device chips or breaks within the first 6 months, there is a warranty that covers a replacement at no charge. If the lens chips or breaks after this time period, you are responsible for paying for a new device. The device cost will be a lot less than the original fitting.

Does insurance cover the EyePrint? Most insurances do not recognize the billing codes used for the EyePrint, however we have had several patients succeed in getting partial or full reimbursement from their insurance companies.
