The Wavefront Scleral Lens

Most patients who have suffered vision loss due to keratoconus, refractive eye surgery (LASIK, Radial Keratotomy, PRK, etc.) and many other corneal conditions and diseases, experience a variety of vision distortions known as “higher order aberrations” or “HOA’s). Higher Order Aberrations are complex vision disorders responsible for the perception of ghosting, double vision, glare, loss of contrast, starbursts and halos. When patients require a scleral lens, it is these usually these conditions that they find most bothersome.

Measurement of higher order aberrations cannot be done simply by scanning the surface of the eye. Moreover, while some patients find a measure of relief from a "classical scleral lens," others continue to report significant problems with their vision. Sometimes the problem lies with the posterior cornea, sometimes with the natural lens of the eye, or with an intraocular lens, or elsewhere in the visual system. Research scientists and eye doctors around the world have been working to address these crippling and life altering vision distortions. The instrument seen in the photo below is an aberrometer. The measurements that it provides are known as “aberrometry”.

In order to identify and measure these aberrations, the Ovitz XWAVE aberrometry system seen below is used to send a light into the eye. This light passes through the cornea and the lens and is reflected back from the retina. Distortions in the reflected light are then identified and measured by the XWAVE aberrometry system. Finally, these aberrations (HOA’s) are displayed in 3D on the aberrometer’s computer screen. How light passes through the eye is known as “wavefront” technology. The resulting aberration profile is uploaded to a special laboratory that embeds this information into the optics of a scleral lens so that these HOA’s can be eliminated and the patient’s vision improved. The ARES HOA correcting scleral lens coupled with the XWAVE aberrometry system is the world's first accessible HOA correcting technology. The great majority of patients who we have used this technology on have experienced significant vision improvement.


To Our Patients,

We hope that this letter finds you and your family well. Our community has been through a lot over the past few months, and all of us are looking forward to resuming our normal habits and routines. While many things have changed, one thing has remained the same: our commitment to your safety and visual welfare. You may see some changes when it is time for your next appointment. We made these changes to help protect our patients and staff. For example:

  • Our office will communicate with you beforehand to ask some screening questions. You will be asked the same questions again when you arrive at our office. We'll also be taking your temperature hands free with an infrared thermometer that scans your forehead.
  • Before being seen in our examining rooms all surfaces that you may contact will be cleaned and disinfected. This will be repeated when your examinations are completed.
  • We have hand sanitizer that we will ask you to use when you enter the office. You will also see some in the reception area and in other places in the office for you to use as needed.
  • You will see that our reception room no longer offers magazines and other reading material since those items are difficult to clean and disinfect. We may ask you to wait in your car if you arrive early in order to avoid unnecessary contact.
  • Our schedules will be modified in order to limit the number of patients in the office at any one point in time and to adhere to the appropriate social distancing guidelines.
  • We will do our best to allow greater time between patients in order to reduce or eliminate waiting time and to allow for social distancing between patients.

We are currently in the process of doing a deep cleaning around the entire office and will be installing high powered medical grade HEPA air purifiers throughout the office. We look forward to seeing you again and will be happy to answer any questions you may have about the steps we are taking to keep you and every patient safe in our practice. Thank you for being our patient. We value your trust and look forward to seeing you again.

Dr. Edward L. Boshnick and Staff

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 cornea, or elsewhere in the visual system. With aberrometry, the defects of the entire optical system can now be corrected by a scleral lens.

Retired FDA Advisor says Lasik should be taken off the Market

QUOTE: "Essentially we ignored the data on vision distortions that persisted for years," said Morris Waxler, a retired FDA adviser who voted to approve LASIK. He now says that vote was a mistake."

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

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

Letter of Thanks from a Future Physician

Dr. Boshnick’s dedication to his practice changed my life; I am no longer the little girl with the oversized glasses and the magnified eyes. I am also no longer the girl with a distorted worldview. The first day I left his office with my newly fit scleral lenses, I stood on the street staring at my newly discovered world finding delight in facial expressions, colors, and a world that conformed to its appropriate place in space.

Young Woman Applies to Med School

Good afternoon Dr. Boshnick, I am in the process of applying for medical schools and was wondering if you would be willing to write me a letter of recommendation? I have chosen to write my personal statement (why I would like to attend medical school) based on my experience as your patient, and have also listed my experience of shadowing you as one of my most impactful experiences on my application, and thus feel that a letter of recommendation would hold strongly from you.

Words of Thanks from Peru

Stargazer enjoying night sky again


My dear Dr. B, wanted to thank you again for your expertise, your amazing gift. These past few nights up north by the ocean we have had the clearest skies we have seen in a while. Michael and I have been stargazing for years, with him I've also seen many planets, our moon, our sun and have lost my breath to countless shooting stars. This time though, I was able to see what seemed to be stars within stars, the clarity with which I could focus the sparkles of tiny little lights in the dark sky left me in awe. While we feel very fortunate to be able to enjoy them, I send you blessings for your contribution to my crystal clear experience, again and again, thank you!


Words of thanks

I love the sclera lenses. I NEVER thought I'd say that! They protect my eyes and allow me to do things I haven't been able to do in years. I love that I can manage the pain and have an explanation. I love that they don't pop out. I read on your facebook page a post from a woman who talked about similar experiences.
