[Theoretical bases of convex tonometry and potentialities of its use].
The authors consider the theoretical foundations of the convex tonometry principle: a universal formula is suggested for the calculation of intraocular pressure measured by a tonometer of any preset curvature. They suggest a new microdeformation convex tonometer with a constant deformation diameter, that makes possible tonometry with a less compression than during standard tonometry according to Goldman. The suggested method has been compared with Goldman's technique, and the results evidence a higher accuracy of convex tonometry. Statistical processing of the data has demonstrated that the new method conforms to the international standards. The design of convex attachment helps widen the sphere of practical applications of the new method.
