The iTrace, IOLMaster, and Pentacam devices could be used interchangeably for corneal astigmatism measurement. ![]() On comparing iTrace wavefront and simulated keratometry (SimK) astigmatism, significant differences were observed in the astigmatism magnitude and oblique component (both P 0.05). No significant interdevice difference existed in the astigmatism magnitude, cardinal component, and oblique component (all P > 0.05). Interdevice agreement was assessed using Bland-Altman analysis, paired sample t-test, and one-way analysis of variance. ![]() All corneal astigmatism measurements were converted to two perpendicular components by using vector analysis. The main outcome measures were corneal cylinder power and axis of astigmatism. The analysis included 90 eyes of 90 subjects without ocular disease. It is impact-, solvent- and saltwater-resistant for indoor and outdoor applications. Trace Vertical and Horizontal LED strips are UL certified and IP67-rated for water resistance. The flexible LED will perform in temperatures of -13° to 140☏ and comes with a three-year limited warranty.To investigate interdevice agreement among corneal topography/ray-tracing aberrometry (iTrace), partial coherence interferometry (IOLMaster), and Scheimpflug imaging (Pentacam) for the measurement of corneal astigmatism. The flexible LED strips operate on low voltage 24-volt DC power, while dimming is controlled by TRIAC, ELV, MVL, DMX and 0 – 10 volts.įor customized lighting applications with a maximum 58-foot run, the flexible LED strip can be cut to 2-inch increments with a 2-inch bending diameter, thus enabling precise field installation. Tivoli Lighting also offers a variety of recessed and surfacing mount locking channels to cleanly and discretely install Trace strip in a variety of applications involving indirect and direct view.įor long lasting performance, Trace Vertical and Horizontal LED strips have a UV-stabilized silicone housing that will not yellow or crack. It has a 124.4 beam angle.īoth Trace Vertical and Horizontal LED strips can accept a power feed for all sides: front, side and bottom. It has a 115.8° beam angle. The Trace Horizontal LED strip offers 48, 96 and 144 lumens per watt for low, standard and high output intensities, while consuming only 4.5 watts per foot. The high output Trace Vertical LED strip delivers 87, 174 and 261 lumens per foot for low, standard and high output intensities, while consuming only 4.5 watts per foot. Trace Vertical and Horizontal LED strips are available in low, standard and high output lumen intensities in 2400K, 2700K, 3000K, 3500K, 4000K, 5000K, green, blue, red and amber with a CRI greater than 80. The flexible SMD LEDs provide superior reliability and uniformity of light, making them ideal for outlining structures and replacing traditional glass neon. This versatile LED strip creates direct or indirect continuous illumination with three different fixture styles in horizontal tunable white, vertical tunable white and vertical RGB+W. ![]() With more than 50 years of innovation and linear lighting leadership, Tivoli Lighting introduces Trace Vertical and Horizontal flexible (SMD) LED strips with zero voltage drop for precise color consistency in straight and curved interior or exterior applications. ![]()
