Surgical planning begins with a detailed diagnostic analysis of your vision, and the structures within the eye. Our technician will conduct the diagnostic scans prior to Dr. Demong's examination. Then, once he has completed his examination and has reviewed all the information gathered to that point, Dr. Demong will make his recommendation for your treatment and answer your questions.
Corneal Topography plays an important role in any Surgical Vision Correction Assessment, even if the procedure does not directly involve the cornea. The topographical map can indicate if there is astigmatism present and the degree attributable to corneal shape. This helps Dr. Demong plan the position of his surgical incision so he can optimally compensate for astigmatism. When Implantable Contact Lens Surgery, or Lens Augmentation Surgery is considered, it helps him to calculate the strength of the artificial lens by indicating the degree of corneal involvement in the focusing problem. It also helps to identify early indicators of corneal disease. Finally, it provides an accurate measurement of the corneal curvature, used to coordinate and calibrate other readings.
When you rest your head on the chin rest and gaze into the cone of the Orbscan, you will note a series of very bright concentric rings. There is no contact with the surface of your eye. A series of images will be taken and analyzed and a computerized image is generated for Dr. Demong’s review.

Dr. Demong will want the most detailed information available regarding the depth of the anterior chamber, the area behind the cornea but in front of the natural crystalline lens. The Visante scans the cornea and the iris area to provide this. By measuring the depth in front of the iris, he can estimate whether there is adequate space for placement of an Implantable Contact Lens. He can also look for inflammatory conditions that may exist.
The image is obtained when you lean forward against the forehead rest and gaze into the lens. There is no contact with the surface of your eye. The laser scan produces a high resolution image of your cornea with measurements at multiple points in the center of your vision. It also produces a cross-sectional view of the anterior chamber of the eye with depth measurements at critical points. The image is then generated for Dr. Demong's review.

All intraocular surgery involves some risk to the inner structures of the eye, especially the retina. During your consultation, Dr. Demong will look for irregularities that indicate greater risk of complications, ultimately affecting his recommendation to proceed or not with surgery. The Stratus OCT enables Dr. Demong to view and analyze the retina, screening out irregularities such as swelling, tears or age related degenerative processes that can affect visual outcome. In some cases, following treatment and stabilization of the irregularity, it may still be possible to perform Lens Surgery.
The image is obtained when you rest your head in the chin rest and gaze into the lens. The scan produces a cross-sectional view of tissue layers with measurements at multiple points. The image is then generated for Dr. Demong's review

Lens surgery involves the placement of an artificial lens implant inside the eye. Artificial lens implants are supplied in a variety of prescription strengths that must be selected according to the depth of certain structures within the eye. The IOL Master uses a beam of light to measure the length of the eye at critical points in the center of vision. Based on the measurements, the lens implant that is best suited for your vision can then be selected.
The image is obtained when you rest your head in the chin rest and gaze into the lens. The scan displays the measurements and automatically selects a variety of recommended lens implant strengths with degrees of + or - variability for Dr. Demong's review.

The final measurement of your cornea involves a photograph of the lining of the cornea. The device shows the shape of corneal cells, the number and whether or not there are irregularities that may indicate early corneal disease not detected by any other device. Using this information, Dr. Demong can determine whether the health of your cornea will support recovery after surgery.
You will rest your head in the chin rest and gaze into the lens. There is no contact with the surface of your eye. The system analyzes the cells, calculates the number at various points and generates a report for Dr. Demong's review.
