Applied Optics, 1995
A gradient-index (GRIN) contact lens (CL) is proposed to decrease spherical aberration and to increase the diopter. A plastic radial GRIN rod was successfully obtained by using the vapor-phase diffusion copolymerization technique. The resulting index distribution of the GRIN rod was almost parabolic against the distance from the center axis, and the Δn

Simplified Contact Lens Localizer
Archives of Ophthalmology, 1986To the Editor. —Ophthalmologists have shown that gas-permeable lenses are useful to correct vision following penetrating keratoplasty. 1 We have achieved greater acceptance among our patients by modifying the marker dots on the contact lenses. A dot of indelible ink has traditionally been used to designate a right contact lens. We have found that four

Specialist contact lens fitting
Contact Lens and Anterior Eye, 2013What is meant by the term ‘specialist contact lens fitting’? Or put another way, what would be considered non-specialist contact lens fitting? Is there such a thing as routine contact lens fitting? Soft or silicone hydrogel fitting for daily wear would probably be considered as routine contact lens fitting, but would extended or flexible wear remain in

Computerized Contact Lens Fitting
Optometry and Vision Science, 1991A keratometer with a standard and a large mire was used to estimate the corneal apical radius and p value. A computer program used this information to determine an optimum fitting contact lens. A fitting set was used independently to determine the optimum contact lens by conventional clinical assessment.
