After receiving dilating drops, how long do you recommend that patients wait before driving?

Do not plan on driving for 4-6 hours after receiving dilating drops. For safety, we recommend that you bring a driver as the drops will cause your vision to become blurry and make your eyes sensitive to light.


Would you advise patients to have refraction done after their eyes are dilated?

No: the drops used to dilate eyes cause your vision to become blurry. Refraction and dilation (for scans and internal examinations) should not normally be done on the same day.


Do patients need to have their eyes dilated every time they come to see the doctor for an internal eye examination?

Unless otherwise instructed by the doctor, patients coming in to see the doctor for an internal eye examination need to have their eyes dilated. Dilated eyes enable the doctor to obtain the best possible view inside the eye.


Do patients need to have their eyes dilated when they come to have their vision checked for glasses or contacts?

No. If patients are scheduled for a refraction ONLY (glasses/contacts test), then no dilation is required.


Can patients have multiple scans/photographs done on the same day they are visiting the doctor?

Theoretically, yes. Practically, this can create long “wait times” for patients. We recommend OCT scans on the same day as your visit, and glaucoma screening on a different day. Notes: <ol><li>OCT scans can take 3-5 minutes and are usually done when the patient is already in our clinic.</li><li>We prefer to schedule glaucoma screening for a different day because it takes a long time to set up and complete, and our clinic days, even though we start at 6am, are usually very heavily booked.</li><li>We also have multiple days when we do photographs for Diabetic Retinopathy screening in all of our clinics.</li></ol>


If the TEH works by appointments, why do patients still need to plan on being in the clinic for over an hour?

Some procedures can take as long as 2 hours. Some patients require multiple procedures. If dilation is needed before the procedure is done, this could add another 15-30 minutes to the process.


If I have a referral letter from a family practice doctor (General Practitioner) or optometrist, how long does a first appointment typically take? And, what does it typically entail?

First time appointments usually take at least 2 hours and this is usually discussed with patients before they come to the clinic. First time appointments usually start with specific processes such as data collection via taking patient histories and doing specific scans. Depending on the patient’s needs, expectations regarding timeframes are discussed with patients who have appointments before they come to the clinic.


If I DO NOT make an appointment, will you still see me?

Patients who come to our clinic without appointments are asked to make an appointment and return at the appointed time OR are accommodated AFTER the patients with appointments are seen. Even if these “walk-in” patients come at 5 am, they still need to wait because they did not contact us in advance to make an appointment. To get an appointment, we encourage you to call the clinic location that is most convenient for you.

If the TEH works with an appointment system, why might a patient be seen several hours after the appointment time?

With each patient, we usually begin the process as close to the appointment time as possible. In unusual circumstances, we sometimes need to fit in emergency cases. When this happens, it could cause bottlenecks in our work flow, but we get to rescue someone who might lose their ability to see. While we do our best to work “by appointment,” some cases take longer than anticipated. To give the best possible care, and still be sensitive to time, we are continuously improving our processes to be more efficient and reduce the amount of time patients have to wait.

Is it safe to have an MRI after cataract surgery?

Yes, it's safe because the replacement lens is not made from a magnetic material. However, any magnetic items (such as a pacemaker or inner ear implant) should be discussed with your doctor before an MRI.


Would the TEH still see a patient if they cannot afford to pay on the same day they receive treatment?

Yes, we will have a conversation with the patient and make mutually-acceptable arrangements. Please be sure to let the receptionist know this when you are making your appointment.


What will today's visit cost?

Cost depends upon the services provided. To ensure you have this information, please ask this question when you call to make your appointment. Related: <a href="/services">See Our Services</a>
