AAO Congress 2004 New Orleans, Louisiana

The participation of Optikon to the AAO 2004 Congress was particularly successful. The total number of attendees this year was very satisfying surpassing initial expectations.

The Optikon 'micro system' for vitreoretinal surgery

One of the most important challenges the ocular surgeon has faced in recent years has been to minimise the trauma to the structure of the eye. Optikon has designed, with the assistance of Dr. Guido Lesnoni, a new instrument set for vitrectomy with 0.6mm (25 gauge) diameter instruments.

Automated decision tree classification of keratoconus from videokeratography

Classification and prediction are common tasks in the biomedical sciences. Several machine learning classification methods exist including Bayesian classifiers, decision trees, neural networks, statistical regression, and others.

Automated Classification of Keratoconus: A Case Study in Analyzing Clinical Data

Topological spatial data can be useful for the classification and analysis of biomedical data. Neural networks have been used previously to make diagnostic classifications of corneal disease using summary statistics as network inputs.

Ramping Up For Custom Ablation The Schwind Approach

Today's ophthalmology clinics must be ready to meet high patient-satisfaction demands. In refractive surgery, we have to achieve excellent outcomes with respect to visual acuity and night vision. We must also strive to make induced aberrations obsolete and to offer patients with unsatisfactory outcomes after earlier treatments a new perspective.

Corneal topography and Wavefront analysis

The relatively recent introduction of Wavefront Analysis (WA) in ophthalmology has engendered shifting attitudes toward the utility of Corneal Topography Analysis (CTA). At first, CTA seemed to have little utility for refractive surgery design because wavefront data alone appeared to be sufficient to calculate an elation patterns.

Gender Differences in Cone Apex Location in Keratoconus

Cone location has been previously described in a small number of keratoconus subjects. Classically keratoconus is described to have inferior steepening with upwards of 11% of eyes having steepening at locations other than inferiorly. [...] This report describes the location of the steepest region of the cornea in a large cohort of keratoconus subjects by gender.

Clinical applications of the aberrometric functions of the Keratron-Scout

recent innovative development in the Keratron and Keratron Scout topographers, called Corneal Aberrometry, allows the analysis of the optical properties of the cornea due to its shape. With these instruments, thanks to the measurement of corneal height obtained by projection of Placido rings and ''Arc-step'' reconstruction of the corneal surface profile, it is possible to obtain measurements with accuracy on the order of a micron.

The Keratron Scout and Wavefront Analysis

The Keratron Scout is a portable and modular computer-assisted corneal topographer, which can be used hand-held, fitted on a generic slit lamp with a slide adaptor, or intra-operatively with a weight-balanced arm and sterile disposable covers.
