Purpose We assessed the accuracy of lens power calculation in highly myopic patients implanting plus and minus intraocular lenses (IOL). Methods We included 58 consecutive, myopic eyes with an axial length (AL) > 26.0 mm, undergoing phacoemulsification and IOL implantation following biometry using ...
The lower whisker represents the first data point greater than the lower quartile minus 1.5× the interquartile range. Similarly, the upper whisker represents the last data point less than the upper quartile plus 1.5× the interquartile range. Outliers were plotted in small black dots. For the ...

Parents were considered myopic if they required corrective lenses for distance vision. Data for this study was derived from 1979 children (aged 6–12 years), who attended the visit in 2001 (baseline), 2002 (1-year follow up) and 2006 (5-year follow up) visits. Fundus imaging was only ...

World-Class Lenses! We are currently using in Miami, Florida the Christie 1.4-1.8:1 HD with true Intelligent Lens System, an eighteen pounds son-of-a-gun measuring 14" inches long by 5.50" wide at the front glass Each projector is equipped with two input card slots to ensure flexibility ...
Therefore, there is a strong relation between the flowing current and the emitted optical power. There is essentially no output power below a certain threshold current, and above the laser threshold the output power grows roughly in proportion to the current minus the threshold current. Power ...
Featuring advanced BSI pixel technology, the VD16GZ provides high relative illumination (RI) uniformity up to the image corners, which enables users to select lenses with different CRA with limited impact. The following figure presents the CRA tolerance range in lens selection for maintaining a RI...
One drawback of these methods is that the resulting RI of cleared samples does not match the working RI medium generally used for LSFM lenses. This RI mismatch leads to the presence of low-order aberrations and therefore to a significant degradation of image quality. In this paper, we ...
While X-ray computed tomography (XCT) is pushed further into the micro- and nanoscale, the limitations of various tool components and object motion become more apparent. For high-resolution XCT, it is necessary but practically difficult to align these to
