Routine postoperative nursing management
Postoperative refraction Postoperative refraction and provision of spectacles (if needed) are essential to ensure the best possible visual outcome for a patient. This is important because satisfied patients will encourage others in the community to undergo cataract surgery. During the 4–8-week follow-up appointment, refract both eyes and accurately check the visual acuity. Make sure you underst...
متن کاملCalibration and monitoring of spectrometers and spectrophotometers.
We have delineated some of the factors affecting the performance of spectrometers and spectrophotometers in the clinical laboratory and have presented some of the methods for verifying that these instruments are functioning properly. At a minimum, every laboratory should perform periodic inspections of spectrometric functions to check wavelength calibration, linearity of detector response, and ...

15 صفحه اولAssessment of the Sources for Disagreement between Two Spectrophotometers
Agreement between different models of spectrophotometers is increasingly being recognized as an issue in the industry. Brand owners are requesting color tolerances that are in some cases too tight to be met when using different make and model spectrophotometers along the supply chain. This often means that printers are being required to purchase a different model of spectrophotometer for each p...
متن کاملInvestigation of the wavelength accuracy of brewer spectrophotometers.
The wavelength accuracy of the Brewer spectrophotometer in the 280-360-nm spectral range is improved by a new grating-drive mechanism and a new dispersion function derived from the Brewer geometry. With the new mechanism, the reproducibility of wavelength settings for spectral emission lines is better than 0.3 pm (0.0003 nm) and, with a thermally compensated version, the effect of temperature i...
