“…The Icare (Icare Finland Oy, 02600 Espoo, Finland) is a modern rebound tonometer that does not need topical anaesthesia to obtain a measurement. [3][4][5][6][7] The tonometer is based on a new measuring principle, in which a very lightweight probe makes momentary contact with the cornea. It can be used by assistant medical staff 8 and shows a degree of agreement with Goldmann applanation tonometer (GAT), that is satisfactory for the purposes of identifying cases of significant elevation of intraocular pressure (IOP).…”

“…1,[8][9][10][11] In the current study using IOPen, the median IOP was 3 mm Hg lower than the GAT or ORA IOPs. Other studies of the ICare reported that 63.2% of cases had IOP values that differed from the IOP values obtained with GAT by 3 mm Hg or less, a limit considered clinically relevant.…”

Purpose To compare the intraocular pressures (IOPs) obtained with the IOPen rebound tonometer, Goldmann applanation tonometer (GAT) and the ocular response analyzer (ORA) and investigate the effects of corneal biomechanical properties on IOPen measurements. Methods A total of 198 normal eyes were included in this cross-sectional and randomized study. Three measurements were taken using IOPen. Agreement between tonometers was calculated using the Bland and Altman limits of agreement (LoA) analysis. Results The median IOPen IOP was 3 mm Hg below the GAT (Po0.001), 3 mm Hg below the ORA IOP similar to Goldmann (IOPg), and 3 mm Hg below the ORA IOP corrected using corneal parameters (IOPcc)(Po0.01). The LoA width between the IOPen and GAT IOPs varied between 13.92 (mean IOPen IOP) and 15.99 mm Hg (third IOPen measurement). The central corneal thickness (CCT) was unrelated to IOPen measurements (P40.05). Corneal hysteresis (CH) and corneal rigidity factor (CRF) were correlated with IOPen and GAT. Conclusions IOPen underestimated the IOP compared with GAT and ORA. The effect of measurement quality or measurement order on IOPen was low. CCT did not affect the IOPen, but the CH and CRF did. The LoA width between the IOPen and GAT IOPs was higher than between the ORA IOPg or ORA IOPcc and GAT IOPs.

“…In five studies 145,165,189,190,209 (36%), cases were selected consecutively. In eight studies 106,145,154,165,190,[209][210][211] (57%), individual measures taken within 1 hour were reported and the same clinical data were available for interpretation as would be in clinical practice. Ten studies 106,107,145,154,165,167,184,207,209,211 (71%) reported whether or not the examiner(s) were masked to the results.…”

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...
