Corneal Topography

Advanced Technologies

Corneal Topography and Wavefront Aberrometer

Corneal topography is the measurement of corneal curvature assisted by computer analysis. Wavefront Aberrometry is a measure of how accurate light passes through the optical system of our eyes. The eye’s optical system includes the cornea, the internal lens as well as the fluids inside the eye.

Our advanced technologies allow us to measure these items and if an irregularity is detected the doctors can determine the best strategy for vision correction. We are able to view the irregularities in Total or separate out the Corneal and the Internal contributors. This allows us to determine the source of the optical irregularity.

This information helps in diagnosing corneal diseases such as keratoconus as well as in defining areas of corneal distortion seen in cases of ocular injury or past surgeries. Internal distortions in many cases show up well before a clinical cataract is diagnosed. This diagnostic procedure is also essential for patients being considered for refractive surgical procedures (such as LASIK or PRK).

Dear Patients,

Please be advised of some of the changes we have implemented to keep you safe while you visit us during this COVID-19 pandemic.

Safety is priority here at Orangeville Optometric Centre. Here are some of the measures we have included:

• All patients will be fully screened for symptoms / travel history, contact history etc.
• A telephone interview will be conducted the day before your visit to minimize the amount of time spent in the office.
• Separate exits and entrances to ensure no cross contamination.
• Staff will be wearing full Personal Protective Equipment.
• Patients will be required to wear a face mask at all times.
• Increased deep cleaning and sanitizing all surfaces after every patient interaction.
• Physical distancing observed.
• Reduced patient volumes to enhance patient safety.
• Patients are requested to wait in their car and enter only when instructed by our support staff.
• Requesting patients enter the building alone and have their driver or companion wait in their car. Exceptions will be made for those who need assistance.
• All doctors and staff health status will be monitored on a daily basis.

This COVID-19 situation presents an enormous challenge to us all. Working together is the best way to weather this crisis.

Please be advised that the above measures may change as the regional and provincial authorities require us.
