What we’re doing to help slow down the spread of COVID

Due to the current COVID-19 situation, our office has implemented several new safety protocols to protect both staff and patients.

Mask requirement!

Temperatures taken upon entrance of the office of all patients and staff

Screening COVID questionnaire.

Digital phoropters instead of manual phoropters to decrease patient/doctor time.

Limited Appointments to decrease the number of patients in our office to allow adequate physical distancing

Sneeze guards at the front desk, slit lamp, and pupilometers.

Pure&Clean disinfection of each room every patient. Pure&Clean is the leading supplier of hypochlorous acid that is nontoxic to human cells yet is EPA proven to use against the novel coronavirus that causes COVID-19.

We are proud to introduce the Herkau H-75 Ultraviolet Disinfection Cabinet at our Deerbrook and Greenway locations. These amazing devices utilize UV-C light to completely sterilize each frame in the office. The ultraviolet sterilization process used in these cabinets is lethal to virtually 100% of all microorganisms, ensuring a safe frame buying experience for every patient.

Q&A | What is Dry Eye Syndrome?

How do I know if I have Dry Eye?

Dry eye can cause quite a few symptoms, anything from the eyes actually feeling dry to the eyes watering often, or having a burning, itchy, or irritated feeling. One of the most common symptoms is the eyes feeling gritty or like something is in your eye. Most people will often experience blurred vision since the tears, which comprise the outermost surface of the eye, are unstable.

Is there anything I can do to prevent DES?

Dry eye is multi-factorial, and each person’s dry eye is unique to them. To help prevent dry eye, make sure to consume 8 to 10 glasses of water per day to avoid dehydration. Some nutritional supplements, such as fish oil and flax seed oil, can contribute to a more stable tear layer.

Remember to blink regularly and take breaks often when on a computer, cell phone or when watching television. During times of the year when there is less humidity, a humidifier might be helpful to provide more moisture in the air.

We are pleased to announce that all three of our Vision Source locations will be reopening for service during the week of May 4th, 2020.

During this difficult time, we have made adjustments to our services to ensure the health and safety of your patients, our staff, and our Doctors.

For the Protection of Our Patients, we have implemented the following procedures in our clinics:

Limited Appointment Scheduling - in order to ensure we are able to properly disinfect and adhere to Social Distancing Guidelines set forth by our local authority.  Certainly, urgent and emergency patients will be prioritized.

Fever Free Environment - Temperatures will be taken upon entering the clinic of all patients, staff, and doctors.  Anyone with 99.5 degrees or higher will be asked to reschedule.  Anyone who is taking a fever-reducing medication such as ibuprofen or acetaminophen will be asked to reschedule once the medication is clear from their system so we can be sure of an accurate temperature reading.

Pre-Screening Questionnaire - We will continue to ask any patient with URI symptoms to reschedule their appointment until they have been asymptomatic for 3 days or have a negative COVID test.

Face Covering - We are requiring everyone entering our clinics to wear some type of facial covering such as a homemade mask, scarf, bandana, or handkerchief.

Wash hands and sanitize - Upon entering the office, everyone will be asked to sanitize their hands.  Additionally, we will request they sanitize their hands before re-entering the business area.

All Vision Source staff with direct patient contact will be required to wear a mask.

Social Distancing - We are limiting the number of patients in our office and are asking, when possible, only the patient enters our clinics for their visit.  Please ask the person with your patient to stay in their car.  We can text them if they need their assistance.

When scheduling patients, we will be:

  1. Asking them if they have been diagnosed with COVID or been in contact with someone who has been diagnosed with COVID.  In those cases, we will postpone seeing the patient unless emergent.
  2. We will ask if they have any current symptoms of COVID.
  3. They will be notified that upon arrival to our office they will have their temperature taken.
  4. We will ask the patients NOT to bring family members with them into the office and we ask patients to wait in the car until they are called inside for their appointment.
  5. We will ask the patient to bring their own mask or face covering.  All of our doctors and any staff who will have direct patient contact will be masked.

Thank you for your support and understanding during these unprecedented times.

Please stay safe and healthy.
