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.


The Zernike polynomials.

This chapter is not written for the scientist or researcher whose daily work is laced with references to mathematical concepts and applications. It is written for the health professional whose mathematics education is a distant memory.


AAO Congress 2002 Orlando, Florida

The participation of Optikon to the AAO 2002 Congress, which was held in Orlando from October 20th to 23rd, has been very satisfying even if the total number of attendees this year was lower compared to previous editions.


Sales and Service course held in Rome

In order to keep our distribution network updated about our product range, answer their questions and allow a hands-on training on our new instruments, Optikon regularly organizes courses for all our distributors; the most recent one was held in our premises from September 16th to September 20th, 2002.


Pupil Location under Mesopic, Photopic, and Pharmacologically

PURPOSE: To determine whether there are systematic changes in pupil location with changes in the state of pupil size and with other ocular variables.


Corneal, Ocular and Internal Aberrations Before and After LASIK surgery

To evaluate the correlation between eye wavefront or 'Ocular-OPD', from a Shack-Hartmann wavefront analyser, and 'Corneal-OPD', from a reflective arc-step corneal topographer, on a set of low-aberration normal pre- and post- LASIK eyes. To evaluate the change in aberration pre-post LASIK with both methods. To map the 'Internal OPD' and to verify whether it remains stable before and after surgery.


Evaluation of Donor Tissue With a New Videokeratoscope. The Keratron Scout

To evaluate the percentage of corneas with an epithelial surface quality sufficient for a reliable screening of donor eyes with keratoconus and after photorefractive keratectomy (PRK) or laser in situ keratomileusis (LASIK) treatment for refractive errors.


Software Increased One OD's RGP Fits

Some time ago I wished for a way to fit RGP contact lenses without the need for extensive trial lens sets or empirically fitting lenses from Ks and refraction, which was less than satisfactory.


A New Clinical Instrument For The Early Detection Of Cataract Using Dynamic Light Scattering And Corneal Topography

A growing cataract can be detected at the molecular level using the technique of dynamic light scattering (DLS). However, the success of this method in clinical use depends upon the precise control of the scattering volume inside a patient's eye and especially during patient's repeat visits.


EIKON: Rigid gas permeable contact lenses produced by electronic cast 'Calco' of the cornea.

Calco' lenses are the result of an innovative process developed for the design, realization and fitting of rigid gas permeable contact lenses; the design of the lens traces the morphology of the cornea on which they will be fitted.


The Cornea is Not a Piece of Plastic

The future of laser refractive surgery is exciting with the potential for ever-improved postoperative visual performance. In the past, the operative goal has been 20/20 uncorrected visual acuity with zero residual refractive error.
