The aim of this study was to find out the difference in intraocular pressure value over silicone hydrogel contact lenses by non-contact and rebound tonometry. This study included 60 eyes of 30 patients who did not have any ocular or systemic diseases or contraindications to contact lens use. We measured and recorded the IOP values of each patient without and with Silicon hydrogel contact lenses using Non Contact Tonometer and Rebound Tonometer. We compared the mean values and standard deviation of the measurements in each case using the independent t-test. The mean IOP value found with Non Contact Tonometry was 15.90 ± 2.57 mmHg without contact lens and with Contact lens was 15.73 ± 2.50 mmHg. It is found that the p-value 0.8354 which is > 0.05, thus the difference found is statistically insignificant when measuring IOP without and with contact lenses by Non Contact Tonometry. The mean IOP value found with Rebound Tonometry was 16.00 ± 3.05 mmHg without contact lens wear and with Contact lens was 16.02 ± 2.89 mmHg. It is found that the p-value 0.6858 which is > 0.05, thus the difference found is statistically insignificant when measuring IOP without and with contact lenses by Rebound Tonometry. Silicone hydrogel soft contact lens does not significantly affect IOP values measured with NCT and Rebound tonometry, and thus Rebound tonometry and non-contact tonometry can be reliably performed over silicone hydrogel CLs.
