  • Is there a way to change the distance between my pupils? Little-Known Facts About Orbital Expansion Surgery
  • EFIL Staff | 2020-01-09 14:58 Hit : 844


Advances in technology allow for medical procedures that were not possible in the past. 

Lasers can be used to cut and reshape the eye to improve visual acuity -- Lasik/Lasek. Bone and tissue in the eye socket can be removed or pushed in to make more room for protruded eyeballs to sit more comfortably in the face. These kinds of procedures can even be done with minimal scarring. 


With that said, is there a way to change the distance between the pupils? Our medical expert says, "yes!" Let's take a medical look at what changing the distance would involve. 


The interpupillary distance, or pupillary distance, is the distance measured between the center of the pupils of the eyes. The distance is measured in millimeters, and plays an important role in the general feel of a face. To go about changing the distance, orbital expansion surgery would have to be performed.


In orbital expansion surgery, orbital bone (the bone that makes up the eye socket) can be cut and removed or pushed in. Depending when on what part of the orbital wall is cut determines how the pupillary distance can change. 


The orbital wall is made up of three walls, respectively: the inferior wall, the medial wall, and the lateral wall. When cuts are made to the medial wall, the innermost wall, the eyes move closer together naturally closing the pupillary distance. When cuts are made to the lateral wall, the outermost wall, the distance between the eyes grows farther apart resulting in a widening pupillary distance. 


The distance between the pupils of the eyes might not seem important, but a subtle difference of a few millimeters can make a surprisingly big difference.
