Bullous Keratopathy post-Lasik Treated with GVR Scleral Lens

This patient underwent LASIK surgery in both eyes in 1998. 2 years later when his vision began to fail he underwent a 2nd LASIK operation in 2000. In 2004 his left eye suffered a complete 360 degree retinal detachment which led to complete vision loss in this eye. In 2014 this patient's left eye became extremely painful. He visited a number of eye doctors earlier that year seeking relief from the pain. None of the medications given to him worked to help this patient. In November, 2014, this patient visited our office. We noted at this visit that the patient's left eye was extremely inflamed and that this eye was completely blind and without light perception. When we examined his left eye with a technology known as "optical coherence tomography" or OCT, it was apparent that the LASIK flap in this eye was separating from the underlying cornea. In addition, the outer layer of the cornea was coming "undone" a condition known as bullous keratopathy. In an effort to avoid the necessity of having this patient's left eye removed we fit his left eye with a GVR Scleral lens. The intention was to protect this seriously damaged eye from the environment and the blinking action of the eyelids. In addition, by covering the exposed corneal nerves with this lens we were hoping that this patient would not experience pain any longer. For the past 12 months, this patient has been wearing his scleral lens comfortably on a daily basis without any pain or discomfort. In the photo below left you can see this inflamed, cloudy blood vessel laden cornea. The "OCT" image below right shows a cross-section of the damaged cornea. The 2 curved lines at the top of the image represents the front and back surface of the GVR Scleral lens. The space between the back surface of the lens and the front surface of the cornea is filled with saline solution. The curved convex images on the corneal surface represent the outer layer (the corneal epithelium) of the cornea separating from the underlying cornea much like wall paper coming off of a wall. The horizontal split within the cornea is the LASIK flap separating from the underlying corneal stroma. This patient visited us last week for his semi-annual examination. He has been very happy with his scleral lens as without it he suffers from unbearable pain.

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
