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

Orbscan, Keratoconus

Bausch & Lomb’s Orbscan® IIz provides a powerful diagnostic system that allows much greater understanding of the cornea than mere topography. This is particularly important when diagnosing corneal dystrophies such as keratoconus. Most current topography systems scan the surface of the eye at standard points to develop a map that is used to look for corneal problems such as keratoconus. The Orbscan II acquires over 9000 data points in 1.5 seconds to make a very detailed map of the entire corneal surface (11 mm), and analyze elevation and curvature measurements on both the anterior and posterior surfaces of the cornea. These maps are very important in the diagnosis of various forms of keratoconus. Both anterior and posterior maps of the cornea developed by the Orbscan can aid in the diagnosis of keratoconus. Combined with other clinical observations, the Orbscan is an invaluable aid in the diagnosis and treatment of keratoconus.

The Orbscan provides more comprehensive pre-op diagnostics and planning for many types of surgery including surgeries for keratoconus. In addition to this, the Orbscan can give exclusionary criteria so that keratoconus, pre-keratoconus, and corneal thinning can be identified to optimize outcomes. The Orbscan II may help explain reasons for decreased visual acuity post-op, and is designed to allow the surgeon to more accurately prescribe follow-up treatments for LASIK as well as other forms of eye surgery, if necessary. Treatments for keratoconus can be planned for with a greater level of detail.

Advantages of the Orbscan when evaluating a patient with keratoconus include:

  • Acquires over 9000 data points in 1.5 seconds
  • Analyzes elevation and curvature measurements on both anterior and posterior surfaces of the cornea and can offer a possible diagnosis for abnormalities, including keratoconus
  • Capable of detecting and analyzing posterior corneal abnormalities where corneal anomalies (such as keratoconus) can first appear
  • Features dynamic, Windows-based platform designed to integrate continuing advances via upgradeable software
  • Customizable quad maps show any combination of measurements in one convenient format
