The ETD is used to measure eye and head movements in space with great accuracy and precision.<\/div><div class=\"hds-credits\">Credits: NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Laser surgery to improve eyesight is widespread, and technology developed for use in space is now commonly used on Earth to track the patient\u2019s eye and precisely direct the laser scalpel during the procedure. <\/p>\n\n\n\n<p>The human eye can hold steady so a person can see a fixed point clearly, even while tilting or shaking his or her head. This reflex requires the brain to constantly interpret information from the inner ear to maintain balance and stable vision. An essential feature of this sensory system is the use of gravity as a reference. <\/p>\n\n\n\n<p>The ESA (European Space Agency) <strong><a href=\"https:\/\/www.nasa.gov\/mission_pages\/station\/research\/experiments\/explorer\/Investigation.html?#id=172\" target=\"_blank\" rel=\"noopener\">Eye Tracking Device<\/a><\/strong> experiment researched mechanisms involved in this process and how the brain\u2019s frames of reference are altered in space. The experiment used a specially designed headset fitted with image-processing chips that track the eyes without interfering with the wearer\u2019s normal work. Results showed that balance and the overall control of eye movements are indeed affected by microgravity. These two systems work closely together under typical gravity conditions, but microgravity can cause them to become somewhat disassociated. <\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1334\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"image of astronaut wearing eye testing device\" style=\"transform: scale(1); transform-origin: 28% 0%; object-position: 28% 0%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png 3008w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=300,195 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=768,500 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=1024,667 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=1536,1001 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=2048,1334 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=400,261 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=600,391 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=900,586 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=1200,782 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/06\/ahh_et_improved_eye_surgery.png?resize=2000,1303 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">ESA astronaut Thomas Reiter conducts the Eye Tracking Device experiment on the space station in 2006.<\/div><div class=\"hds-credits\">Credits: ESA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The engineers realized that in parallel with its use on the space station, the device had potential for applications on Earth, including tracking eye position without interfering with the surgeon\u2019s work in laser surgery.
