Review of Calibration Methods for Scheimpflug Camera [PDF]

Journal of Sensors, 2018
The Scheimpflug camera offers a wide range of applications in the field of typical close-range photogrammetry, particle image velocity, and digital image correlation due to the fact that the depth-of-view of Scheimpflug camera can be greatly extended according to the Scheimpflug condition. Yet, the conventional calibration methods are not applicable in

Postoperative Capsular Bag Distension Syndrome: Case Report of an Early Case Following Athalamia due to Vigorous Eye Rubbing. [PDF]

Case Rep Ophthalmol Med
Introduction Capsular bag distension syndrome (CBDS) is a rare complication of phacoemulsification, characterized by fluid retention in the capsular bag leading to reduced visual acuity, a myopic shift, and a risk of pupillary block. Case Presentation We report the case of a 65‐year‐old male who developed CBDS after rubbing his eye vigorously ...
