Clinical use of transpalpebral diaton tonometry after keratophotorefractive surgeries T. Dzhafarli MD., A. Illarionova MD. Purpose: The purpose of the study is to evaluate the clinical use of transpalpebral #scleraltonometry, reliability of its application in patients with #refraction anomaly in pre- and postoperational periods. Methods: The following factors were exclusion criteria from the study: cornea, upper eyelid and sclera #pathology. We have analyzed the results of prospective comparative case series clinical study in 98 patients (194 eyes) with #ametropia, from which 39 persons (76 eyes), who had been subjected to #excimerlaser vision correction. All patients were subject to the comlpete refractive examination, including #keratotopography, wavefront-aberrometry, US-biomicroscopy, #pachymetry corneal thickness in central zone, #IOP was measured with #Goldmann applanation #tonometer, #pneumotonometer & transpalpebral scleral Diaton tonometer using traditional methodology. Results: In the patients who had not been subjected to #photorefractivesurgery the mean #applanation IOP was 16.1±2.6 mmHg, the mean IOP evaluated with #Diaton 14.7±2.5 mmHg. At that correlation between values of the #applanationtonometer and Diaton was highly reliable r=0.73. The mean of the real IOP after applanation value conversion was 15.4±2.4 mmHg. #Pearsoncorrelationcoefficient between real IOP & Diaton result was 0.89. In the groups of patients, who underwent #photorefractive vision correction, the mean applanation IOP 12.4±2.91 mmHg, modified taking into account #keratometry IOP rates 13.9±3.0 mmHg, mean diaton-tonometry result 15.1±2.75 mm Hg – increase of correlation coefficient from 0.51 to 0.81. Conclusions: The cornea thickness is an important factor in IOP evaluation and monitoring, and necessitates the inclusion of #cornealpachymetry in the program of examination the patients with suspicion of #glaucoma and hypertension, especially after various #keratorefractive surgeries while using the traditional corneal methods of tonometry. At the same time clinical application of #transpalpebral #scleral diaton tonometer makes it possible to evaluate IOP using only one device.
