Laser Vision Correction using the Pentacam
. It utilizes a sophisticated Scheipmflug camera system that scans the anterior eye (cornea, anterior chamber, iris, and lens) and takes up to 25,000 measured data points in a scan time of 2 seconds per eye. From all this data a 3D model of the eye is constructed that can be viewed and analyzed by the doctor. The data collected allows doctors to view the eye from 25 different angles with a three dimensional analysis of all the structures mentioned above. Most importantly for potential laser vision correction patients, it allows the doctor to have a precise elevation map of the back surface of the cornea unparalleled by any previous technology. This information helps doctors to make sure the recommendations they make for laser vision correction will be as safe as possible. The 3D capability of the image allows doctors to see if lens implants for very near or farsighted patients might be a better option than laser surgery. The doctors can also grade the level of cataract development in the lens of the eye and follow its progress with subsequent scans. For patients who have undergone previous laser vision correction who are now, or at some time in the future, will be in need of cataract surgery, doctors are able to more accurately calculate the lens implant replacement power with the true corneal curvature measurements (keratometry readings) that are provided by the Pentacam.
