Abstract
In this paper we present an update on the Mini-Excimer photorefractive keratectomy (PRK) laser system with an emphasis on the scanning device. We also compare the systems of various manufacturers. This paper also presents PMMA ablation profiles and clinical results from China with over 100 cases of myopic corrections ranging from -2.5 D to -12 D. In contrast to the old technology which uses industrial-type high-power excimer lasers, the advanced Mini-Excimer system uses the most recent technology involving a compact, high repetition-rate excimer laser operated at a much smaller beam spot size of (0.8 - 1.2) mm in a scanning mode which requires a beam energy per pulse of only (0.9 - 1.2) mJ on the corneal surface to achieve the same range of fluence (or energy density) (160 - 200) mJ/cm2 as that of the high-power excimer lasers.
