The photo below is of an Eye Print Pro Scleral lens on an eye that suffered 2 separate retinal detachments within a 4 month period requiring 2 separate vitrectomy surgeries (surgeries to remove the interior "gel" within the eye known as the vitreous and replacing it with saline). In addition, cataract surgery was done after the first vitrectomy. Several months later, the intra-ocular lens dislodged into the posterior chamber of this eye requiring emergency surgery. For this reason, a 2nd vitrectomy was done along with a retinal surgical repair procedure known as a scleral buckle. Eye Print Pro Scleral lens technology allows us to make a lens from an impression of the front surface of the eye. A very gentle impression material known as Polyvinyl Siloxane is placed on a plastic holder which is then placed on the front surface of the eye and under the eye lids. After a few minutes, the plastic holder with the eye mold is removed and sent to our laboratory where a scleral lens matching the exact contour of the cornea and the white portion of the eye is made. This technology is designed to help patients whose ocular surfaces have been extremely altered due to disease and surgery see clearly once again. In the case of the eye shown in this photo, without the Eye Print Pro, the vision in this eye is less than 20/800. With the Eye Print Pro lens this eye is corrected to 20/20 vision without any distortions. The 2nd photo shows how the impression material appears on the eye. The procedure is fast and painless.
This little girl and her family visited us from Argentina. Last year she suffered a penetrating ocular injury to her left eye which resulted in a torn perforated cornea and significant damage to the internal ocular structures within this eye. She underwent cataract and vitrectomy surgeries in her left eye and in addition retinal surgery for a retinal detachment. Repair of the torn cornea required significant suturing. When she entered our office for the first time the visual acuity in her damaged eye was hand motion at just a few inches from her eye. Because of the irregular cornea and exposed sutures on the corneal surface, we are fitting this little girl with a GVR Scleral lens. It is our hope that this lens will protect the healing cornea and neutralize the visual effect of the distorted cornea. In the near term, we expect this lens to improve her visual acuity to about 20/600 or better and in addition to provide her with some peripheral vision. In the lower left photo you can see the scleral lens over the traumatized cornea. In the lower right photo you can see the scar tissue along with the corneal sutures holding the cornea together. Many months (and possibly years) of exams, office visits and lens changes will need to be done before we can know the final vision her left eye will be capable of.
In 2004, this patient developed in his left eye a relatively rare eye infection known as Pseudomonas Keratitis. This infection is caused by an organism found in lakes, soiled water and unclean swimming pools. This patient feels that got this infection from swimming in a pool. Several weeks after he became infected he developed a red eye along with a corneal ulcer. He visited several eye doctors who eventually were able to subdue the infection. The result, however, was a deep scar in the center of his cornea which needed to be treated with a laser in order reduce it's intensity. 4 months after the laser treatment this patient was referred to our office. The corneal scar left his cornea with a very irregular surface. His best corrected vision in his left eye was less than 20/200. Eyeglasses and contact lenses were unable to correct his vision. In early 2005 we fit this patient's left eye with a GVR Scleral lens which allowed him to see clearly (20/25) and comfortably once again. Over the last 10 years we have seen this patient on a yearly basis. His vision has remained stable and his eye has remained healthy.
About 12 years ago this young man wore his soft lenses for an extended period of time without removal while he was away from home at sleep-away camp. When soft lenses are worn without removal for an extended period of time and without being cleaned and disinfected, the bacteria count within the lens will build and toxins from the bacteria will "eat away" at the cornea. What resulted was a devastating corneal ulcer in his right eye which scarred and severely distorted his cornea. For over 4 years, this young man had very little vision in his right eye, in fact he was legally blind with best corrected vision of 20/400 with eyeglasses. 8 years ago we fit this patient's right eye with a GVR Scleral lens. With this lens he can see 20/30 in his right eye without any distortions and all day wear with excellent comfort. If it were not for this type of lens technology, this young man would have had to have a corneal transplant.
