WHY IS THE PICTURE SO IMPORTANT
Since the color composition of the ArtificialIris is custom designed on the basis of a photo printout utmost care should be taken to achieve the highest quality photograph and printout for each eye.
Since we cannot see the patient´s natural iris ourselves, we need to rely on the pictures we get. The color of every computer screen and printer shows different results of a photo. That is the reason why evaluated hardcopies of the pictures are still necessary.
If the clinic/doctor is not set up for high quality photography and photo printouts we recommend to send the patient to a professional photographer of their choice to provide the patient and doctor with high quality photos and printouts of each eye from which one needs to be approved by the doctor as target color for production. The following information should help to take adequate photos. Please find further information in the presentation "photo directives".
HOW TO TAKE GOOD PICTURES
Independent from the affected eye it is best for production and the clinical discussion to have two pictures: one of the eye giving the target color and one of both eyes together. Ideally these should be standardized pictures of the size 9x13 cm (3½x5'') showing the iris with a diameter of approx. 4 – 6 cm (1.5 – 2.5'').
HOW TO EVALUATE PICTURES
Please check if the color patterns of the natural iris match the printout´s color composition when compared under the same illumination. It is best to hold the printout right next to the patient’s eye. Furthermore please check if the conjunctiva on the printout is white and if the color patterns of the natural iris match the printout’s color composition. After photo evaluation the picture to be used for production should be signed and dated by the surgeon.
Tips for a good Picture
- Illuminate the eye of the patient evenly, in order not to produce shadows on the iris.
- Make a white balance with your camera at the exact place where you want to take the photo of the patient‘s eye (- maybe use a white or grey chart).
- Take care that the iris of the patient is completely visible and in focus.
- Slit lamps, fundus cameras or any video cameras are not suitable for taking good pictures
- Good, even illumination of the eye is essential; try not to use flash, since it can overexpose the photo and cause reflections off the cornea
- Laser printers are usually not as good as ink-jets
- Photo paper shows better results than normal copy paper
