Intraocular Pressure Measurement with the Noncontact Tonometer and Rebound Tonometer through Plano Soft Contact Lenses

Purpose: To investigate the accuracy of intraocular pressure (IOP) measurement through a plano soft contact lens (SCL) in situ by a noncontact tonometer (NCT) and a rebound tonometer (RBT). Methods: The IOP of 66 eyes of 33 subjects with no ocular pathology was measured by NCT (tonometer CT-80, TOPCON, Japan) and RBT (iCare rebound tonometryTM, Tiolat Oy, Finland). IOP measurement was repeated through plano SCL (ACUVUE OASYS?, Johnson & Johnson Vision Care Inc., USA) in situ. Statistical analysis was performed using the paired t-test. Results: Mean IOP measured by NCT was 13.10 ± 2.52 mmHg without SCL and 12.95 ± 2.56 mmHg with SCL. Mean IOP measured by RBT was 14.13 ± 2.94 mmHg without SCL and 13.84 ± 2.75 mmHg with SCL. No significant statistical differences were found between IOP measured with and without SCL (p=0.47, p=0.11 respectively). Conclusions: Reliable measurement of IOP by NCT and RBT can be achieved through plano SCL. J Korean Ophthalmol Soc 2012;53(5):662-667
