Vitrectomy after Lasik due to Floaters

One of the complications associated with LASIK surgery are vitreous floaters , more commonly called floaters. The images below were taken with a technology known as "optical coherence tomography" or simply OCT. These images are all of the same eye. The first 2 images are cross sectional images of the macular area of the retina, where clear sharp vision begins to take place. The 3rd image is a direct "head on" view of this same section of this retina. Many years after LASIK surgery was done on this eye, numerous floaters began appearing in the eye in a very short amount of time. This patient referred to what he was seeing as "huge sheets of floaters". Rather than live with these floaters, he elected to undergo a vitrectomy, which is a surgery done to remove the bulk of the ocular interior (the vitreous) and replacing this gel-like substance with saline solution. One of the complications associated with a vitrectomy is that cataract surgery will need to be done about a year later. This eye underwent cataract surgery one year later. Due to complications of the cataract surgery, an additional surgical procedure needed to be done which included yet another vitrectomy. I saw this patient 2 days after the 2nd vitrectomy and took the 2nd and 3rd OCT images. To better explain, the first OCT image was taken about one year prior to the 2nd vitrectomy but after the 1st vitrectomy. Note that the layers of the retina are distinct and smooth when compared to the 2nd OCT image. After undergoing the 2nd vitrectomy, the intraocular pressure in this eye dropped dangerously low to 4 mm. A normal intraocular pressure is about 16mm. This low eye pressure condition is known as "hypotony" and can lead to permanent vision loss or even to loss of an eye. In the 2nd image, note how jagged and wrinkled this retina appears. The 3rd OCT image is a direct view of this same part of this patient's retina. Note the wrinkles along the retinal surface. After the 2nd vitrectomy, this patient noted a great deal of visual distortions. We caught this condition in time to allow the proper medical treatment which increased the intraocular pressure to a normal level. This patient is now seeing much clearer with this eye but still is noticing some distortions in the visual field with this eye.

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
