The DNA profiling technique was first reported in 1986
In the 1950s, the microkeratome and keratomileusis technique were developed in Bogotá, Colombia, by the Spanish ophthalmologist Jose Barraquer. In his clinic, he would cut thin (one hundredth of a mm thick) flaps in the cornea to alter its shape. Barraquer also investigated how much of the cornea had to be left unaltered in order to provide stable long-term results.[7] This work was followed by that of the Russian scientist, Svyatoslav Fyodorov (1920-2000), who developed the Radial keratotomy (RK) in the 1970s and designed the first posterior chamber implantable contact lenses (phakic intraocular lens) in the 1980s.[8]
