Whether blue, brown or Hazel, the pupil is the entrance to our vision. At Dishler Laser Institute we are continuously upgrading our technology both for research and for patient care. Our most recent acquisition is the Neuroptics pupillometer. This small handheld piece of equipment has an amazing amount of technology packed into a small package. We are all familiar with the concept of the pupil of the eye and it is similar to the aperature of a camera. It is the opening which admits light into the eye that we use for our vision. Any light outside of this entrance pupil is blocked by the iris, or the colored portion of the eye. It is only this tiny pencil of light which is so critical and can make the difference between excellent sight and blurry vision. The size of this pupil becomes important to measure in vision correction surgery and prior to the Neuroptics device we had fewer options. Our prior measurement device which is widely used is the Colvard pupillometer. Although similar in outside appearance to the Neuroptics, it requires the user to guess the pupil size based on a ruler on the screen. This was an improvement from the previous method of holding a ruler up to the eye, but is not nearly as accurate at the Neuroptics device. This is one more example that there is a lot more differences between LASIK centers than one might at first imagine.
