The Scheimpflug videophotographic camera is a modified slit lamp camera that uses a narrow slit beam and Scheimpflug optics to increase apparent depth of field (enabling simultaneous focusing of the entire anterior segment). Area densitometry measurement of scattered light intensity gives a cross sectional image of the anterior segment. In 1995, Lasa et al demonstrated the use of Scheimpflug photography1 to assess posterior capsular opacification (PCO). Subsequent studies have correlated the values obtained with visual acuity.2,3 The system is efficient and reliable for PCO evaluation with good intraobserver and interobserver reproducibility.4,5 This has been verified by comparison with histological findings.6 Delayed opacification of Hydroview (H60M) intraocular implant lenses (Bausch & Lomb, Rochester, New York, USA) has been reported.7 In our patient series we find this to give rise …
