Abstract :

Purpose: The purpose of this study was to evaluate the accuracy of the disposable applanation tonometer head as a potential substitute to the standard reusable applanation tonometer head for IOP measurements and to determine the influence of Central Corneal Thickness (CCT) on IOP measurements with these tonometer heads and determine effect of corneal incision on the post-operative CCT. Methodology: The IOP of 30 post cataract surgery patients was measured with disposable and the standard reusable tonometer head after informed consent. Corneal thickness was recorded in operated and un-operated eye. Results: The mean IOP using the reusable tonometer head in both eyes was 13.4�?±3.11 mmHg and with the disposable head was 13.11�?±3.18 mmHg with the mean difference of 0.29�?±0.08 mmHg. Disposable tonometer recorded higher IOP in patients with thicker cornea (0.1�?±0.2 mm Hg) than in patients with thinner cornea (0.4�?±0.3 mmHg) and lower in the normal CCT patients. Conclusion: The disposable tonometer prism provides a reliable, effective and safe alternative to the reusable tonometer prism with the advantages of eliminating the need for chemical disinfection and the risk of cross infection.
