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

Riboflavin Treatment – Removing the Epithelium

Riboflavin treatment has shown great results in some studies in strengthening the cornea of patients with keratoconus. The treatment acts by increasing cross-linking within the cornea stroma with the application of ultraviolet light to the riboflavin solution. In order for the treatment to be effective both the UV light and the riboflavin must be absorbed by the corneal stroma. Above the stroma rests the epithelium, the upper layer of the cornea that sheds throughout the week. Treating the epithelium with riboflavin and UV light is ineffective as it sheds itself regularly. Additionally, the epithelium acts as a barrier to both the UV light and the riboflavin solution.

Studies show that without removal of the epithelium, both the UV light and the riboflavin are highly reduced and the effect of corneal cross-linking is also significantly reduced.  Additionally, some surgeons have expressed concern that by not removing the epithelium, the treatment is putting the patient at a higher risk for cataracts or macular damage since the riboflavin is less absorbed by the stroma and often a higher level of UV light is required if the epithelium is not removed.

Most ophthalmologists currently providing riboflavin treatment for corneal cross-linking are currently using an epithelium off method for maximum effectiveness.  Removing the epithelium results in a more uncomfortable recovery but maximizes the effectiveness of the treatment.
