Intrastromal corneal ring segments (ICRs) to treat myopia were introduced about 20 years ago but there were limitations and as such alternative methods were preferred. However, interest in ICR treatment of myopia peaked once more about a decade ago as a result of several authors' work.

According to Prof. Baikoff, "With the constant evolution of technological improvements, the femtosecond laser will replace manual surgery, with only a few exceptions, such as deep lamellar grafts or the use of the 'big bubble' technique. At the moment, the femtosecond lasers are not routinely associated with more or less complex preoperative imaging techniques, which could provide assistance during surgery. Certain teams are working on this problem."
