Contact lens overrefraction variability in corneal power estimation after refractive surgery[J] . Charlotte E. Joslin,James Koster,Elmer Y. Tu.Journal of Cataract & Refractive Surgery . 2005 (12)Joslin CE,Koster J,Tu EY.Contact lens over refraction varia-bility in corneal power estimation after ...
Contact lens fitting included refractive correction, over refraction testing, confirmation of the central position and corneal coverage of the lenses. A slit lamp (Topcon DC3-slit lamp) with a digital video camera was used to assess whether the contact lens could completely cover the cornea and ...

We have verified that the Pilkington Diffrax lens behaves optically as a diffractive bifocal contact lens. The longitudinal chromatic aberration of the lens is similar to that predicted by theory, both on and off the eye. The over-refraction with the lens on the eye is similar to the ...
A rigid lens is able to revise the natural shape of the cornea into a new, better refracting surface than a soft lens and thus tends to provide more consistent improvement in refraction for people who have astigmatism or an irregular corneal surface. Older polymethyl methacrylate rigid contact ...

In this manner, the contact lens is capable of gradually releasing into the eye over an extended period of time a suitable and predetermined quantity of a compound which delays the myopia progression. In a second aspect, the invention further relates to a packaging comprising a soft contact lens...
Objective and subjective refraction, and corneal radius were measured at 0, 30, 60 and 90 min after lens removal. The changes in refractive power were evaluated between measurements over time. The other parameters such as types of lenses, fitting and wearing conditions were also assessed. Results...
