Lasik in 2007, Vision Worse with Retreatments, now 20/20 with GVR Scleral Lens

The patient standing next to me recently visited us from the Canary Islands seeking help in restoring vision to her right eye. In 2007, this patient underwent LASIK surgery in both eyes. When her vision began to fail she underwent another LASIK procedure in each eye in 2009. This 2nd procedure made the vision in her right eye worse. In 2010, this patient underwent photo refractive keratectomy (PRK) in her right eye in an attempt to restore the vision she lost from her previous surgeries. What resulted was additional vision loss and ocular pain. In early 2015, once again, in an attempt to improve the vision in her right eye this patient underwent a 4th surgery known as photo therapeutic keratectomy (PTK). The purpose of this last procedure was to smooth out the corneal irregularities and eliminate the corneal opacities created by her previous surgeries. What resulted from this last surgery was an additional reduction in her vision and a dramatic increase in her ocular pain. This patient visited 2 of the most respected eye institutions in Spain seeking help. The doctors at both University eye clinics told her that her only option was corneal transplant surgery. When this patient first visited us, the visual acuity in her right eye was 20/300 and 20/30 in her left eye. We recently fit both of this patient's eyes with GVR Scleral lenses. She is now seeing clearly (20/20 in each eye) and comfortably once again. The pain she was experiencing in her right eye is gone. The last time this patient had decent vision in her right eye was 8 years ago. In the lower left photo if you look carefully you can see the corneal scars created by her 4 surgeries. In the lower right photo under higher magnification you can see the dense elevated corneal scars. The corneal damage created by these eye surgeries prevented the outer corneal layer (the epithelium) from healing. Because of this the corneal nerve endings in the center of her cornea are exposed to the environment and the blinking action of her eyelids. The purpose of this scleral lens is to not only provide quality vision once again but to protect the cornea from the environment and to promote healing. This eye will never need to undergo corneal transplant surgery. One last point: this patient had suffered from depression and anxiety from her vision loss and the thought of needing a corneal transplant. This is now a thing of the past.

The Wavefront Scleral Lens

The corneal irregularities created by refractive surgeries, such as LASIK and RK, are responsible for ghosting, halos, starbursting, and loss of contrast sensitivity. These "higher order aberrations" may exist on both the anterior and posterior. With aberrometry, the defects of the entire optical system can now be corrected by a scleral lens.

Autologous Serum for Dry Eyes

Dry eye conditions are among the most challenging conditions faced by refractive surgery patients. With autologous serum, blood is spun down to plasma, forming an eye drop that helps rehabilitate the cornea.

Optimum Infinite Gas Permeable Material

I am happy to announce that our Global Vision Rehabilitation Center will be designing and fitting all of our “high need” patients with the Optimum Infinite gas permeable contact lens material. The Optimum Infinite material is the most oxygen permeable material ever to be approved by the FDA. In addition, this newly FDA approved material includes a UV lens blocker. Now for the first time, with certain patients, wearing a scleral lens made with the Infinite material under extended wear conditions can be considered.

SMAP 3D Scleral Lens Design

NEW: Powerpoint presentation on SMAP 3D

Last year we introduced an exciting piece of technology that has allowed us to custom design a scleral lens much more accurately. It is the SMAP 3D, which is a computer attached to a dedicated camera that allows us to obtain a 3 dimensional image of the entire front surface of the eye, including the cornea and the surrounding white portion of the eye (the sclera). Up until now there has not been any technology that would allow us to measure the ocular curvatures outside the cornea. The SMAP allows us to do this. Read More

Blurred Vision, Burning Eyes: This Is a Lasik Success?

EyePrint Pro

EyePrintPro technology creates a scleral lens based on a mold of the cornea. The molding is accurate to 1 or 2 microns and fits perfectly because it exactly mirrors the irregularities of the individual corneal surface. The technology is well suited for post-Lasik, Keratoconus, RK, eye injury, and corneal transplant patients. Read More in this PDF about EyePrintPro Scleral Lens Technology
