In this paper, the results, discussions and conclusions concerning selected variables relative to orthokeratological effects and procedures are presented. The data, clinical observations and subsequent analyses suggest that corneal modification with contact lenses is not clearly understood. Hypothesis are offered to explain certain results obtained, to(More)

In this paper, the rationale, statistical methods and results of this study are given. Specifically, it is shown that contact lenses produce clinical effects on the eye which are statistically significant. Moreover, the orthokeratology procedure was found to produce more corneal and refractive change than conventional contact lens wear. Variability and(More)

In this paper, the recovery profiles of changes produced by a defined orthokeratological technique are presented and discussed. The manner and degree in which the eye responds after the removal of contact lenses was shown to be highly individualistic in nature. Even so, certain trends were evident. It was found that the alterations produced by(More)

Changes in unaided visual acuity, corneal integrity and lens position are differentially affected by contact lens fitting procedures. The effects on these parameters, from contact lenses fitted by defined conventional and orthokeratological techniques, are given and compared to each other and to a group of non-contact lens wearers. General trends and(More)

Since contact lenses are responsible for producing corneal change it is essential to rigorously examine for variables involved. The need to control corneal change further dictates that fitting procedures or techniques should also be critically evaluated. Given in this first of a two part series is a background discussion of contact lens prescribing(More)

The effects of contact lenses, fitted by defined conventional and orthokeratological techniques, are given and compared to a group of non-contact lens wearers. Data presented include changes in corneal curvature, topography, refraction and astigmatism. General trends and variability of data are discussed in conjunction with pertinent clinical observations(More)
Recent software and hardware advances in the field of electron backscatter diffraction have led to an increase in the rate of data acquisition. Combining automated stage movements with conventional beam control have allowed researchers to collect data from significantly larger areas of samples than was previously possible. This paper describes a LabVIEW™(More)

Historically, clinicians have observed or gained the clinical impression that contact lenses had some effect on myopia and/or its progression. However, a review of the literature on the effects of contact lenses upon myopia control reveals conflicting opinions and conclusions. This paper presents a collage of research endeavors, clinical observations, and(More)
