A 3-step treatment for keratoconusApril 1st 2014
The arrival of advanced therapeutic modalities for keratoconus has provided ophthalmologists with a growing menu of treatment options. The author discusses the challenge of determining which treatment is the best to use and highlights his experience with a triple procedure and a four-stage approach.
Predicting the position of pIOLsMarch 1st 2014
Predicting the position of an iris-fixated pIOL is important to ensure intraocular structure health is maintained. In this article, Dr Soltani Moghadam describes his recent study that found AS-OCT imaging technique to be particularly useful as a preoperative simulation technique.
Corneal anterior segment imaging has emerged as a screening tool for refractive surgery, cataract and glaucoma. In this article, the authors discuss their recent study that identified a set of normative data to correct for sources of bias in pre-surgery screening.
In this article, Dr Cervino discusses how his recent study examining the quality of anterior segment images obtained with posterior segment OCT devices is good enough to obtain repeatable measures of anterior segment parameters manually using external analysis software.
Measuring ocular biomechanics with a new Scheimpflug-based deviceMarch 1st 2014
The CorVis ST, a new Scheimpflug-based device, has the potential to analyze ocular biomechanical properties for further research. Here, Dr Nemeth discusses his recent study analyzing the repeatability of data obtained with this new device.
AS-OCT, IVCM find and track epithelial downgrowth after penetrating keratoplastyNovember 1st 2013
Non-invasive imaging modalities, such as high-resolution anterior-segment optical coherence tomography (AS-OCT) and in-vivo confocal microscopy (IVCM) imaging, may be more sensitive to identifying and monitoring epithelial downgrowth, compared with routine light biomicroscopy in patients undergoing penetrating keratoplasty, and will perhaps replace more invasive diagnostics in these patients.
Flat corneas produce unpredictable visual outcomes after PRKJuly 2nd 2013
Flat, steep corneas with keratometry values of less than 35 D do not have a predictive effect on the risk of visual acuity loss after myopic photorefractive keratectomy (PRK), claims a paper in the Journal of Refractive Surgery.
