Visual stability of laser vision correction in an astronaut on a Soyuz mission to the International Space Station

“…7 The etiology of the IOP rise has been hypothesized to result from increased episcleral venous pressure, orbital pressure on the globe, choroidal expansion, or a combination of the three. [6][7][8] Although long-duration studies of IOP in microgravity have not been performed, short duration space shuttle and head-down studies suggest that the eye may rapidly undergo adaptive changes to blunt the initial spike in IOP. 6,8 During descent, the Soyuz module falls toward Earth, reaching a deceleration of C4.0 to 4.5 Gx (eyeballs in).…”

“…[6][7][8] Although long-duration studies of IOP in microgravity have not been performed, short duration space shuttle and head-down studies suggest that the eye may rapidly undergo adaptive changes to blunt the initial spike in IOP. 6,8 During descent, the Soyuz module falls toward Earth, reaching a deceleration of C4.0 to 4.5 Gx (eyeballs in). A series of 4 parachutes are then deployed, slowing the rate of descent until 1 second before touchdown, when 2 engines on the bottom of the descent module ignite to further reduce the force of impact.…”
