Abstract

Posterior curve measurements were performed on 18 separate lenses by means of the Hydro-Vue Soft Lens Analyzer. 20 measurements were made per lens to determine this instruments ability to provide accurate and reproducible data. Six lens manufacturers were represented with three different powers used from each company. It was found that no significant difference existed between lens manufacturers in their ability to provide reproducible base curve data. Likewise, variance in measurements could not be related to the power of the lens. When our findings were compared to the base curve stated on the vial it was seen that a significant discrepancy occurred in 2 cases, thus demonstrating a need for a tool the clinician can use to moniter his fitting variables.
