Preoperative assessment of corneal and refractive stability in soft contact lens wearing photorefractive candidates.

Purpose: This pilot study compared traditional methodologies; manifest refraction and keratometry, with that of newer technologies; corneal topography, and optical pachymetry, in assessing corneal and refractive stabilization after soft contact lens wear in photorefractive candidates. The timeline differences among these various technologies in determining refractive and corneal stability were investigated.

Methods: This was a masked prospective observational clinical study of full-time soft contact lens subjects on various wear schedules, all eligible candidates for photorefractive surgery.

Validity of fluorexon disodium versus sodium fluorescein for use in Goldmann tonometry.

Purpose: To evaluate the safety, validity, and comfort of 0.35% fluorexon disodium and 0.4% benoxinate (Flura-Safe) compared with the gold standard of 0.
