To Our Valued Patients,

With the evolving situation of the Coronavirus (COVID-19) pandemic and under the guidelines of the Health Officer of the Alameda and Contra-Costa Counties, we will begin the process of re-opening our offices on Monday May 4th in order to provide needed eye and vision care. Moreover, cataract and all other non-cosmetic surgical procedures will soon resume.

Please keep in mind that in order to maintain social distancing protocols and to limit further transmission of the virus, we will be working with a reduced staff and seeing a fewer number of patients as compared to our “normal” schedule. Priority will be given to the most urgent medical cases. We will be implementing a number of measures (including altered check-in/check-out procedures, limiting the number of patients in the office and waiting room, face covering for all persons, temperature screening, etc) that will change your experience in the office. In addition, we will be ramping up our already strict disinfection policies and we will continue to monitor and abide by all local, state and, federal guidelines. Please bear with us through this new reality as these changes are designed to protect you and our staff.

We hope to see you soon and appreciate your trust in us to continue to meet your eye care needs. Stay safe and stay healthy!

The Turner Eye Institute Team

Emerging technology for keratoconus

The billion dollar Hubble Telescope has been assisting astronomers for nearly two decades now, gathering information about our own Milky Way galaxy and the rest of our universe. The entire project has not been without problems, however. Shortly after its launch in 1990, it was discovered that the mirror contained significant spherical aberration that affected the performance of the telescope. A system was developed called COSTAR, Corrective Optics Space Telescope Axial Replacement, which used two mirrors in the light path to correct for the aberration in the main mirror. With this adaptation, astronomers could achieve the accuracy and clarity that they were hoping for.

Adaptive optics relies upon a secondary set of mirrors that are in place to adjust for errors within the main optical system. While the Hubble is one example of this, our own eyes can benefit from the advances made through adaptive optics. The measured point spread function in our eyes is far from perfect. In people with keratoconus and other corneal diseases, these optical error are even more significant. It is possible, however, to reflect light through a mirror that adapts light to these optical errors and produce a clearer picture on the retina.

Deformable mirrors (DM’s) have become very important for this. Once a person’s point spread function is measured, a deformable mirror can adapt itself to these measurements. In modern LASIK surgery, surgeons are measuring patient’s point spread functions in order to customize the LASIK surgery to improve vision results. In keratoconus treatment, the progress of the disease can be tracked through the measurements of a patients “wavefront” or point spread function. In cataract surgery, newer lenses are using principles of optics to provide clearer vision through adaptive optics. Doctors can also use adaptive optics to view the back of a patient’s eye, the retina. In fact, adaptive optics now allows researchers to view individual photoreceptors in a live human eye.

As research continues, we expect to see greater improvement in the application of adaptive optics. Perhaps LASIK surgery will continue to improve or adjustments can be made to allow LASIK to correct not just myopia, hyperopia, and astigmatism but top also decrease the symptoms of presbyopia. Many companies are looking at multifocal or aspheric corrections with LASIK surgery. Researchers are using adaptive optics to measure the extent of the vision loss in keratoconus that is caused by the cornea and how much is caused by loss of neural information. The field of adaptive optics appears to be able to provide many new and interesting discoveries. Keratoconus is one important disease that stands to benefit from the advances in research of adaptive optics.
