Testimonials

“The Mastel PhD scalpel has taken the accuracy of my relaxing incisions to a new level. When used with the guide, it makes smooth, precise cuts that have eliminated much of the variability in the technique. It is ideal for both the experienced and beginning surgeon.” – Douglas D. Koch, MD, Houston, TX

“The diamond seats nicely into the cornea and with the guide ring you get perfect arcs every time. Pachymetry adjusted diamond depth gives me consistently good results for what I do. I routinely use it for a diopter or less of pre-existing corneal astigmatism. For greater than one diopter or more I go with the Toric IOL. With the multifocal I get great results. The diamond with the Inset Profile footplate is very kind to the epithelium and the design is superior for visualization.” – Kerry Solomon, MD, Charleston, SC

“Ingenious multi-use titanium handles like the PhD II allow surgeons to use a single, multi-step depth based diamond for LRI’s, AK’s, scleral pockets, and paracentesis. One of my nurses assumed that PhD was the name of the instrument because it was ‘so smart.’ When a Mastel diamond blade is treated well it can provide years of perfect performance through thousands of cases. Incisions on soft eyes, lamellar cuts through perforated eyes and layer by layer dissection of sclera on the way to Schlemm’s Canal are made simple with these “works of art”. Perforations during LRI’s just don’t occur with Mastel products.” – James S. Lewis, MD, Philadelphia, PA
