Contact lens fitting today
RGP materials In choosing appropriate materials, it is important to remember that keratoconic patients (as well as in other primary corneal ectasias) demand high levels of comfort because they wear their lenses for long periods of time. With steep high minus lenses, which are often required, materials with high dimensional stability are recommended in order to minimise lens distortion. Mid to h...
متن کاملKeratoconus: Diagnosis, contact lens fitting and management
Numerous studies have reviewed the prevalence of keratoconus. Estimates lie between 50 and 230 per 100,000 in the general population, approximately one per 2000.2,7,8 When considering the prevalence of keratoconus the differing diagnostic criteria used in different studies need to be taken into account. A much higher prevalence may be found as corneal topography is used more, thanks to its grea...
متن کاملImplants: techniques for fitting and removal.
The two letters 2 describing individuals’ different techniques for implant removal that have appeared in recent issues of this Journal are timely. Routine removal with or without refit is common practice throughout the UK as implants have become widely available and popular. It is not yet clear whether introduction of Nexplanon (MSD, Hoddesdon, UK) will lead to fewer difficult removals. It is e...
متن کاملComputationally and Statistically Efficient Model Fitting Techniques
In large-scale stochastic simulations, analysis with sufficient accuracy is often extremely time consuming. The complexity of the analysis is exacerbated with increasing dimensionality of the parameter space and sudden abruptness in the topology of the input-output response surface. This paper addresses computational issues in fitting and generating error measures of simulation metamodels, demo...
متن کاملContact lens fitting after photorefractive keratectomy.
AIMS/BACKGROUND This study evaluated contact lens fitting and the longer term response of the photorefractive keratectomy (PRK) cornea to lens wear. In PRK for myopia problems such as regression, anterior stromal haze, irregular astigmatism, halo aberration, and anisometropia have been reported. Certain patients therefore require contact lens correction to obtain best corrected visual acuity (B...
