WebGoldmann applanation tonometry, the force is changed until the defined area of flattening is achieved. This is simple in theory but awkward in practice. Difficulties in achieving a proper endpoint are numerous and well documented, and they explain why this instrument is so dependent on the operator. WebGoldmann applanation tonometry (GAT) has long been the gold standard for IOP measurements and its accuracy is such that it is used to determine the validity of other tonometers. The Perkins tonometer uses the same principal as the GAT, but is a hand-held tonometer and does not require a slit-lamp biomicroscope ( Figure 7.25 ).
