PURPOSE We present a prototype of the hand-held dynamic contour tonometer (HH-DCT) and prospectively compare this HH-DCT with the well-established Perkins applanation tonometer (PAT) and the TonoPenXL (TPXL). METHODS In a prospective, single-centre, randomized study, intraocular pressure (IOP) readings were taken in random order using HH-DCT, PAT and TPXL(More)
PURPOSE Corneal collagen cross-linking (CCL) with riboflavin and ultraviolet A irradiation has recently been introduced for treatment of corneal ectasia. Yet a CCL-induced increase in corneal rigidity may interfere with intraocular pressure (IOP) measurements. In an investigation of the effect of CCL on the accuracy of IOP measurements, IOP readings before(More)
Die dynamische Konturtonometrie (DCT) ermöglicht direkte transkorneale Messungen des Augeninnendrucks und der okulären Pulsamplitude (OPA). Ziel dieser Studie war es, herauszufinden, ob die OPA als biometrischer Messwert Aussagen über verschiedene Glaukomformen erlaubt. Es wurden 441 Augen von 222 Patienten in die Studie aufgenommen.
