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

When Was Keratoconus Discovered?

The discovery of keratoconus may have occurred as early as a 1748 doctoral dissertation. German oculist Burchard Mauchart gave a description of a case that may have been keratoconus. He named the problem as staphyloma diaphanum. By 1854, British physician John Nottingham reported the effects of keratoconus and clearly distinguished it from other ectasias of the cornea. Nottingham reported the cases of “conical cornea” coming to his attention, and described several classic features of the disease, including polyopia, weakness of the cornea, and difficulty matching corrective lenses to the patient’s vision.

Five years later, in 1859 British surgeon William Bowman used an ophthalmoscope to diagnose keratoconus, and described how to angle the instrument’s mirror so as to best see the conical shape of the cornea. Bowman also attempted to restore the vision by pulling on the iris with a fine hook inserted through the cornea and stretching the pupil into a vertical stenopeic slit like that of a cat. He reported that he had had a measure of success with the technique, restoring vision to an 18-year old woman who had previously been unable to count fingers at a distance of 8 inches (20 cm). By 1869, when the pioneering Swiss ophthalmologist Johann Horner wrote a thesis entitled On the treatment of keratoconus, the disorder had acquired its current name. The treatment at that time, endorsed by the leading German ophthalmologist Albrecht von Gräfe, was an attempt to physically reshape the cornea by chemical cauterization with a silver nitrate solution and application of a miosis-causing agent with a pressure dressing. In 1888 the treatment of keratoconus became one of the first practical applications of the then newly-invented contact lens, when the French physician Eugene Kalt manufactured a glass scleral shell which improved vision by compressing the cornea into a more regular shape. Since the start of the twentieth century, research on keratoconus has both improved understanding of the disease and greatly expanded the range of treatment options.

In 1989, it was discovered that there is increased enzyme activity which leads to corneal thinning in keratoconus corneas. Corneal thinning causes cone-shaped corneas and visual distortion that are often associated with keratoconus.

In individual patients, Keratoconus is frequently discovered during adolescence. Generally Keratoconus would be discovered during a complete eye exam from an optometrist or ophthalmologist. Signs within the cornea and progressive loss of vision would be signs that lead to the discovery of Keratoconus. Diagnosis of Keratoconus can be made with slit lamp inspection as well as other test such as pachymetry, keratometry, and corneal topography.
