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, our offices are open to provide eye and vision care.

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!

LASIK Glossary

Ablation surgical removal.
Ablation zone area of tissue removed during laser vision correction surgery. The ablation zone can vary in LASIK surgery.
Accommodation the ability of the eye to change its focus from distant objects to near objects. LASIK does not affect accommodation
Acuity clarity or sharpness of vision. LASIK can typically achieve good acuity.
Astigmatism distortion of the image on the retina usually caused by irregularities in the cornea. LASIK can correct astigmatism
Cornea the clear front part of your eye. The cornea is the first part of the eye that bends (or focuses) the light and provides most of the focusing power. During LASIK, a flap is made in the cornea
Diopter is the measurement of refractive error. When used in excimer refractive surgery, diopter is a measurement of the refractive power of the eye. In LASIK and other refractive procedures, a negative diopter value signifies an eye with myopia and positive diopter value signifies an eye with hyperopia.
Dry Eye is a common condition that occurs when the eyes do not produce enough tears to keep the eye wet and comfortable. Common symptoms of dry eye include feelings of stinging, burning, or scratchiness of the eyes.
Endothelium is the inner layer of cells on the inside surface of the cornea.
Epithelium is the outermost layer of cells of the cornea and is the eye’s first defense against infection.
Excimer laser is an ultraviolet laser used in laser vision correction surgery to remove corneal tissue.
Farsightedness is the common term for hyperopia. Farsightedness is now correctable with LASIK.
FDA is the abbreviation for the Food and Drug Administration. The FDA is the United States government agency responsible for the evaluation and approval of medical devices. FDA approved LASIK surgery.
Flap & Zap is a slang term for LASIK.
Ghost Image is a fainter second image of the object you are viewing.
