Scleral contact lens thickness profiles: The relationship between average and centre lens thickness

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...

Lens thickness in early cataract.

The search for environmental factors associated with cataract has produced conflicting evidence and one possible reason may be that environmental influences are initiating events occurring perhaps for short periods many years before loss of sight from cataract. It is important, therefore, to be able to detect the earliest changes of cataract formation so that epidemiological studies have a bett...

Measurement of post-lens tear thickness.

PURPOSE A method to measure the tear film beneath a soft contact lens, referred to as post-lens tear thickness (PLTT), would have many applications to contact lens research. In this study a noninvasive technique for measuring the PLTT is presented. METHODS The feasibility of measuring the tear layer by optical pachometry was first assessed using a model eye. The baseline corneal thickness (B)...
