Low-contrast visual acuity measurements in single-vision and bifocal soft lens wearers

Publikováno v: International Contact Lens Clinic. 27:119-123

Background. We sought to consider the low success rate of bifocal soft contact lenses through low-contrast visual acuity measurements using one popular design. Methods. Visual performance was measured in 23 nonpresbyopic patients with a single-vision

Empirical fitting with polycon II lenses

Autor: Ralph E. Gundel, Herman Kwong

Publikováno v: International Contact Lens Clinic. 26:152-156

Historically, rigid gas permeable (RGP) lens parameters have been determined through trial fitting. Nevertheless, practitioners would likely welcome the opportunity to empirically fit RGP lenses if they could be confident of the outcome. This clinica

Autor: Joseph T. Barr, David P. Libassi, Mae O. Gordon, Timothy B. Edrington, Timothy T. McMahon, Karla Zadnik, Ralph E. Gundel, Larry J. Davis

Publikováno v: Optometry and Vision Science. 73:369-375

Keratoconus is typically managed by a variety of rigid contact lens fitting techniques and lens designs. The two most fundamental fitting techniques are apical corneal touch (including divided or three-point touch) and apical clearance. In the course

Parameter Consistency in Disposable Lenses

Autor: Ralph E. Gundel, Jay S. Rosen, Evan N. Kaplan

Publikováno v: Optometry and Vision Science. 70:672-676

An evaluation of parameter consistency and edge defects as they might relate to premature lens fracture was undertaken for 2 disposable lens types, 50 Johnson & Johnson Acuvue lenses and 50 Wesley-Jessen FreshLook lenses. Diameter measurements varied

Quantitative Analysis of Visual Acuity Through Amber Discolored Lenses

Autor: Evan N. Kaplan, Jay S. Rosen, Ralph E. Gundel

Publikováno v: Optometry and Vision Science. 69:948-952

Discoloration of hydrogel contact lenses is frequently encountered in clinical practice and often precipitates lens replacement. This investigation sought to determine if lens discoloration was associated with a compromise in low or high contrast, hi

Use of Acular LS in the pain management of keratoconus: a pilot study

Autor: Ralph E. Gundel, Jessica O. Yu

Publikováno v: Optometry and vision science : official publication of the American Academy of Optometry. 87(2)

Purpose. The purpose of this pilot study was to determine the efficacy of ketorolac tromethamine 0.4% for pain management in conjunction with rigid gas permeable contact lenses in keratoconus. Any potential side effects and complications of this appl
