Tunnel of Vision

Tunnel of Vision
 
www.dishler.com -- The Neuroptics pupillometer is a state of the art device used to measure the size of the pupil in real life conditions. We acquired this technology in relation to a new FDA study that is beginning soon at Dishler Laser Institute. In learning about this device we are so impressed that we have decided to use it for all of our LASIK evaluations to measure the pupil of the eye prior to surgery. This device uses infrared light to measure the pupil 39 times per second for two seconds and then averages these readings to give an average pupil size which is accurate to 0.1 mm with a digital readout. The human pupil is never stationary and constantly is changing in size depending on lighting conditions. Even when the light level is constant, there are pupil fluctuations known as hippus. We are not so concerned with pupil size in bright light, but in dim light a large pupil can potentially cause issues if not considered prior to LASIK surgery. We measure the pupil in a controlled dimly lit room with the patient focused on a distant object. This is because near vision targets can also make the pupil contract, similar to the effects of bright light, and thus give an artificially small reading of pupil size.Dishler LASIK
