corneal thickness changes after soft contact lens removal
purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...
متن کاملOn-eye performance of custom wavefront-guided soft contact lenses in a habitual soft lens-wearing keratoconic patient.
PURPOSE To assess visual, optical, and fitting characteristics for wavefront-guided soft contact lenses produced for one habitual soft lens-wearing moderate keratoconic eye. METHODS A process for production and evaluation of custom wavefront-guided soft contact lenses was developed. Wavefront aberrations were quantified with the COAS-HD wavefront sensor (Wavefront Sciences); soft contact lens...
متن کاملPredicting visual acuity from wavefront aberrations.
It is now possible to routinely measure the aberrations of the human eye, but there is as yet no established metric that relates aberrations to visual acuity. A number of metrics have been proposed and evaluated, and some perform well on particular sets of evaluation data. But these metrics are not based on a plausible model of the letter acuity task and may not generalize to other sets of aber...
متن کاملPeripheral myopization and visual performance with experimental rigid gas permeable and soft contact lens design.
PURPOSE To evaluate the performance of two experimental contact lenses (CL) designed to induce relative peripheral myopic defocus in myopic eyes. METHODS Ten right eyes of 10 subjects were fitted with three different CL: a soft experimental lens (ExpSCL), a rigid gas permeable experimental lens (ExpRGP) and a standard RGP lens made of the same material (StdRGP). Central and peripheral refract...
متن کاملCorneal Biomechanical Changes Following Toric Soft Contact Lens Wear
PURPOSE To determine the effect of using toric soft contact lenses on corneal biomechanical properties. METHODS We enrolled 33 healthy patients with mean age of 23.18 ± 4.06 and minimal cylinder power of 1 D (-1.98 ± 0.808 SD) and negative history of contact lens use; keratoconic patients were excluded from the study. Toric soft contact lenses (BIOFINITY, Comfilcon A, Coopervision, Southampto...
