If this happens the person will measure more nearsighted or less farsighted than they actually are. The relaxed muscle allows us to more accurately measure the level of nearsightedness and farsightedness. Just making the pupil big is fine for a regular eye exam, but relaxing the lens gives us important information to give you an accurate correction. This technology was derived from NASA's Star Wars Strategic Defense Initiative. The system actively tracks the position of the eye during surgery at a rate of 4,000 times a second, compensating for eye movement.
Patients report being more relaxed during surgery.
Other laser systems rely on the patient focusing on a point of light to ensure the eye remains still during surgery. Even though infection is rare in refractive surgery, everything possible should be done to prevent this occurrence. It is very important to use completely separate sterilized equipment for each eye. If both eyes are done on the same day, we use a completely different set of sterilized equipment for each eye. Some of the lower-priced laser centers cut their costs by not following a complete sterile procedure and by reusing blades.
