“…Several studies compared the reproducibility and reliability of IOP measurements obtained with NCT, DCT, and GAT. [21][22][23][24] In most of these studies, similar reproducibility and reliability were demonstrated with all three devices. In this study, however, the results indicated better reproducibility of measurements for NCT, DCT, and GAT without a contact lens than with one.…”

Purpose To evaluate the influence of silicone hydrogel contact lenses on the intraocular pressure (IOP) measurement using Goldmann applanation tonometry (GAT), non-contact tonometry (NCT), and Pascal dynamic contour tonometry (DCT). Methods We included in the study 40 eyes of 40 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 using NCT without and with contact lenses (groups 1 and 2, respectively), using DCT without and with contact lenses (groups 3 and 4, respectively), and using GAT without contact lenses (group 5). Results The mean IOP value of group 1 was 14.55±2.95 mm Hg and 13.92±2.58 mm Hg in group 2. We detected no statistically significant difference between group 1 and group 2 (P ¼ 0.053). The mean IOP values for group 3 and group 4 were 16.26 ± 2.33 mm Hg and 15.19 ± 2.40 mm Hg, respectively. We detected a statistically significant difference between groups 3 and 4 (P ¼ 0.005).

HTA NIHR Health Technology Assessment programmeThe Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service' . The HTA programme is needs led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects...

The Validity of a New Noncontact Tonometer and Its Comparison with the Goldmann Tonometer

Abstract: The pulse detection feature from this new NCT could capture and monitor pulse waves, thus reducing the variations in the consecutive measurements. The NT-4000 also performed better than the NT-2000 when compared with the Goldmann tonometry.
