Rochester, NY (PRWEB) December 04, 2013

The leading manufacturer of thickness measurement and non-contact measurement solutions, Lumetrics®, Inc. was selected to present at the prominent 2013 OptiFab conference and exhibition. David Compertore, Lumetrics scientist, presented his work on spherical aberration standards of intraocular lenses.

According to the National Eye Institute, by age 80, more than half of Americans have a cataract or have had cataract surgery. A cataract is the clouding of the lens that affects vision. “The majority of modern intraocular lenses are designed with an added correction for the inherent spherical aberration of the human cornea,” explains David Compertore, Lumetrics scientist. “Spherical aberration is a secondary optical property of all lens systems. The spherical aberration correction is designed to sharpen the focus on the patient’s retina and allow them to see added details.”

Compertore and Lumetrics engineers developed a method to provide a measurement standard for spherical aberration using standard lenses, existing tools, and a series of procedures. This process had not been thought of before and solved the problem of lack of calibration standards. Calibration tools are required by all processes in order to standardize in a manufacturing environment.

Compertore explains that this research is important because “manufacturers of intraocular lenses test each lens to confirm the prescribed amount of spherical aberration correction was properly fabricated into the lens.” The test equipment needs to be accurate, and “using our spherical aberration standards, the intraocular lens manufacturers assure the equipment meets the design and will work when inserted into the patient’s eye. Too much or too little spherical aberration may cause blurry vision and this is not easy to correct after the operation is completed.”
