Super Vision

Picking off 20/10 letters on the Snellen chart has become commonplace with Biometric lenses.  However, we recently broke the 20/10 barrier with a female student.  Without lenses her aberrations are off the charts: LASIK over extremely large pupils, and a suspected case of DLK with a large amount of irregular astigmatism in one eye.  She originally sought me out because of an inability to correct her more problematic eye to better than 20/30 with any lens.   With Biometric lenses, her vision was measured at 20/7 in the better eye and 20/8 in the more problematic eye.  I asked her what it was like to be a “medical curiosity.”  In her own words:

“. . . I went to my first **** game this week when they were playing against the Spurs. This week I was at the VERY top of the stadium and the contacts were WONDERFUL! I could see far better than my classmates so we started playing games among ourselves to see who could pick out eye colors from people in the crowd. That’s what happens when you get a group of optometry students together :)   The lenses are doing extremely well. I love them and I can’t thank you enough! My life is so much easier with them, especially during school.”

Needless to say, her low light vision problems are completely resolved with her lenses.

The evolution of the lens in 2012

Someone described to me how they once had an actual physical impression made of their eyes as part of a scleral lens fitting process.  Indeed, this was the process taught to me in school way back in the 20th century.  Since 2007, I have worked to perfect another type of molding process, using 21st century scanning technology to develop a digital mold of the eye using sagittal images.  Working from these images permits us to precisely visualize how the actual lens will fit in relationship to the eye before the lens is made, as opposed to trial and error.  In 2011 we were awarded a U.S. patent for this process.  However, this was just the first phase in the process then envisioned.

In 2012, the Biometric scleral lens embodies the following:

  • More OCT scans for a better fit, quicker fit, improved comfort and stability
  • Better optics using wavefront aberrometry and proprietary process (patent pending)
  • Improvement of 1 – 2 snellen lines of acuity — 20/10 or better in some cases — over standard scleral lenses (data on file)
