At I CARE, if you meet certain essential conditions, Dr. Yeh inserts an artificial ICL implant beneath your iris (= the round diaphragm that gives your eye its color), which corrects your vision without altering the shape of the cornea (the dome-shaped transparent layer that covers the front part of the eye).
As a result, when you reach the age of presbyopia (loss of accommodation, difficulty reading) years later, it will simply be necessary to remove the ICL implant and replace your lens with an artificial one that corrects your vision at all distances. Moreover, since most activities nowadays are done on screens, intermediate and near vision are very important. The surgeon must consider these factors when operating on a patient.
