Gold standard IOP was measured with a Goldmann applanation tonometer (GAT). Effect of central corneal thickness, anterior chamber depth and refractive errors on IOP measurements were also analysed.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The mean difference of IOP by GAT and both the portable tonometers was \u00b1\u200a2.2\u2003mmHg. The analysis indicates minimal difference between IOP readings of both the portable tonometers. The mean difference between two consecutive readings by I\u2010care was 0.01\u2003mmHg. Using 21\u2003mmHg as a threshold for suspected glaucoma, both the portable digital tonometers reported a sensitivity of 38% and specificity of &gt;95%. In the subjects studied, central corneal thickness had statistically significant influence on IOP measurements while refractive errors and anterior chamber depth had no significant influence on IOP measurements with any tonometry.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> The IOP readings by both portable tonometers are comparable and were within clinically acceptable range from GAT.
