Correcting Higher Order Aberrations In The Human Eye
The human cornea accounts for approximately two-thirds of the total refractive power of the human eye. Disorders that distort its shape and smoothness induce irregular astigmatism and higher order aberrations that are uncorrectable with spectacles. Because the refractive index of tear and cornea are similar, a rigid contact lens masks most (9/10) of the refractive power of the corneal surface, including irregular astigmatism. Yet, significant residual HOAs that degrade visual performance remain a significant issue in eyes with certain common corneal disease. The 501(3) nonprofit Boston Foundation for Sight fits these eyes with a unique hard contact lens that is rotationally stable and immobile on blinking. These features make it an excellent vehicle for correcting eye-specific residual higher order aberrations. The Foundation in collaboration with Geunyoung Yoon, Associate Professor at the Institute of Optics and Center for Visual Science at the Center for Visual Science, University of Rochester, is working to customize the optics of the BOS-P to correct eye-specific residual higher order aberrations based on mapping Zernike polynomials and generating correcting front surface optics perturbations.
Speakers:
Perry Rosenthal, M.D.
Born and raised in Montreal, Canada, Dr. Rosenthal received his undergraduate and medical degrees from McGill University and completed a residency in ophthalmology at Harvard’s Massachusetts Eye and Ear Infirmary. During his training he founded the contact lens service at the Infirmary in order to exploit the unique optical benefits of rigid contact lenses in masking irregular astigmatism of eyes suffering from diseased corneas. He then founded Polymer Technology Corp. and led his team in developing rigid, gas-permeable contact lens polymers know as the Boston Lens polymers. This opened the door to his developing The Boston Ocular Surface Prosthesis (BOS-P), an over-sized rigid contact lens which has materially advanced the treatment of many corneal diseases. In 1994 Dr. Rosenthal founded the 501(C)3 nonprofit Boston Foundation for Sight to further his mission of providing this device to all whom it can benefit regardless of their ability to pay. Because of its positional stability, this device serves as an ideal platform for correcting eye-specific residual higher order aberrations. Dr. Rosenthal is Assistant Clinical Professor at Harvard Medical School and a Lauriat of the Tech Museum of Innovation for “Innovation benefiting humanity”
Christopher Ducharme
Chris Ducharme has partnered with Dr. Rosenthal for 40 years as his in-house mathematician. Chris developed the patented DTF CAD-CAM system based on spline functions that serves as the fundamental architecture of the BOS-P and enables its design to be customized for each eye. More recently, he has developed the software that translates the Zernike aberrometry data into the corrective tool path of our single point diamond turning Nanaform lathes
Lynette Johns, OD
Lynette Johns, a graduate of the New England School of Optometry and its contact lens fellowship program is Senior Clinical Associate of the Boston Foundation for Sight and clinical project leader for the integrated aberration-free program which has recently passed its proof of principal milestone.

Cancellations and No-shows:
If the meeting must be canceled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.
We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.
Membership Rates:
| Regular members | $15.00 |
| Student members | free |
NOTE: The extra $5.00 of the non-member dinner fee can be used toward membership dues if the nonmember joins and pays dues for the current year at the meeting.
