Abstract

Purpose: To determine whether the choice of instrumentation affects the quality and precision of corneal cuts during keratomileusis in situ. Setting: Schlosspark-Klinik, Ophthalmology Department, Berlin, Germany. Methods: The study was performed on 54 swine eyes and 3 human corneas using microkeratomes manufactured by Steinway(R), SCMD(R), and Eye Technology(R). The study results are based on micrometric and pachymetric measurements of actual slice thickness. Slice thickness and slice quality were evaluatedusing scanning electron microscopy. Three slices of defined thickness weremade with each keratome. Results: There was no significant difference in the degree of deviation ofslice thickness from the intended value with any keratome. The micrometricmeasurement of the first lamella documented significantly less variation in the actual measurements achieved with the Eye Technology device (P < .01). Ail keratomes tested demonstrated a high degree of congruence between theintended values and those achieved in mean thickness and circularity of the cut. The Eye Technology device demonstrated the best profile and the cleanest margins, followed by the SCMD keratome, which caused minimal distortion of the stroma. The Steinway keratome has a high amplitude and produced 25mu m tears in the margins perpendicular to the plane of the cut. Conclusion: There was no overall difference in cutting precision between the 3 tested keratomes. High-oscillation frequency of the blade resulted in a smooth cut.
