  • "We barely go to optometrists so when we do, we should look for the best! I am super pleased I chose Dr. Pal\'s office. They were helpful from beginning to end, from booking on the phone to my actual visit. Dr. Pal was very detailed and went in-depth about my eye health. She is very patient and made me feel calm. The optician helped me pick a great pair of glasses, they were genuinely friendly which is a huge bonus."

  • "I have been going to Dr. Pal for several years now. My most recent visit on June 6, 2016 was the best experience there that I have ever had. Firstly, the women on the desk were friendly and efficient - a very good prelude to my examination. Dr. Pal, herself, was, as usual, very thorough and encouraging in her examination. And she puts you at ease before we get into the eyes examination by discussing other things in life. That helps to ease any stress I may have. And they now have a man in the office who does that difficult examination (name of which I do not know!). He is so patient and encouraging and made the exam not so difficult for me this time. After all that, I saw Dr. Pal again before I left and she told me my eyes were good! Even had the news been not so good, I believe that I would be able to handle it because I truly believe that Dr. Pal and her staff would have taken good care of me. I will always go back to Dr. Pal and members of her team because I truly believe"

  • " I have been to a few appointments at Dr. Pal\'s office over the last year for dry eye issues and every time it has been a very positive experience. The 3 receptionists at the front desk are warm and friendly. They are attentive and provide a very high level of customer service. I appreciate that they call me by name and remembered conversations we had at previous visits. I find Dr. Pal to be an excellent practitioner who is very thorough with her exams, has a lovely personality and takes the time to answer any and all questions that may arise. I am happy with the computer glasses I purchased and value the honest opinions I received from the staff when selecting frames. It was refreshing to have multiple opinions on styles and I felt they truly wanted me to walk out with a frame that was best suited to me. I highly recommend Dr. Pal \'s office! As a health care practitioner myself, I think all health care experiences should be this personilzed and friendly!"

Corneal Topography


Contents

Introduction

The first surface that light entering the eye encounters is the front of the cornea, the clear, dome-shaped window which covers the iris. Because the cornea provides a major part of the focusing power of the eye, an accurate analysis of its shape and curvature is important in contact lens design or evaluating changes resulting from various disease processes.

Once, the only way to measure any part of the cornea’s shape was the keratometer, which only measured the central 3 millimeters, and in only two directions.

Now, technology has come to the rescue, with a relatively new instrument for measuring shape and curvature called a corneal topographer. In topography, a detailed surface map of the cornea is acquired and recorded by computer, which then analyses thousands of points and generates a shape-map of the surface.

Easy and Helpful

Taking a topographical reading of the cornea takes only seconds and is completely painless. Far from being limited to only 3 mm, the topographer measures the entire cornea, showing changes in curvature from flatter to steeper and any irregularities, similar to a topographical map of a mountain range, with all its hills, valleys, plateaus and cliffs.

The topographer gives the practitioner a printout of the corneal map, with different colours; blue and greenish hues usually describe flatter areas, while steeper curvatures are represented by orange and red.

Absolutely Necessary

A topographical map of the cornea is invaluable in evaluating changes to the corneal curvature that are a hallmark of some conditions like keratoconus, where the cornea begins to become thinner in some areas and tends to bulge outward. Keratoconus is usually treated with rigid contact lenses which help stabilize the corneal curvature and push it back into a more spherical shape; topographical maps are extremely helpful in designing the lenses and evaluating their effectiveness over time.

Refractive surgery is another area where topography is important in planning the type of surgery. In LASIK, corneal tissue is removed by the laser, giving it a flatter profile; topography helps determine how much.

In cataract extraction surgery or clear lens extraction, topography helps determine the power of the implanted lens that replaces the natural lens behind the iris where the cataract is located. In most cases of cataract surgery, the implanted lens allows the patient to see much more clearly than before, even without corrective eyewear. Most people are much less dependent on their eyeglasses than previously.

The Changing Shape of Eyecare

Technology over the past few years has taken giant leaps forward, and provides eyecare practitioners and other health care professionals with options for treatment that were never available before. Better technology from better measurements from better instrumentation equates to better outcomes in just about every area of health care.

Corneal topography is just one aspect of this forward trend, and it is a significant one without doubt. If or when you have it done, take a few minutes to look over your topographical corneal maps, because it is quite interesting.
