New scleral lens incorporates evidence-based design

CHICAGO – The design of the BostonSight Scleral lens, launched here at the American Academy of Optometry meeting, was based on 6 years’ worth of data from more than 7,000 eyes, according to a company executive.

Karen Carrasquillo, OD, PhD, FAAO, FSLS , director of clinical care at BostonSight, told attendees at an academy-sponsored press conference that BostonSight, a nonprofit organization, is an optometry and ophthalmology referral clinic devoted to scleral lenses, with its own manufacturing lab.

“We looked at what patient outcomes were successful from our own data in scleral lens fitting and built that into the BostonSight Scleral lens design,” she said. “It’s evidence-based, data-driven lens design.”

She said that the BostonSight Scleral uses quadrant-specific toric lens design with built-in scleral shape and right and left eye anatomical designs. The lens provides front-surface eccentricity options for aberration control.

“It has the same starting point regardless of patient condition, provides a dependable fit right from the start due to the scleral shape and is based on research,” Carrasquillo said. “There is no need for calculations or special equipment.

“As the architects of spline technology, every parameter change is independent of one another with our spline curve,” she continued. “Clinicians have access to the software and can modify each quadrant independently in real time and see what those changes look like to drive that fit for more accurate end points and also manipulate the sagittal depth and base curve to control and manipulate clearance.”

The lens is available in three diameter options: 18.0 mm, 18.5 mm and 19 mm, she said. – by Nancy Hemphill, ELS, FAAO
