History of Contact lens Flashcards
first describe the concept of a lens that comes into contact with the eye
Leonardo Da Vinci - 1508
described a glass contact lens designed to match the shape of the eye
John Herschel - 1827
Fitted a blown glass lens to the eye of a patient whose eye had been surgically removed
August Müller - 1887
described the first contact lens intended to correct vision
Adolf Eugen Fick (A.E Fick) - 1888
constructed the first plastic scleral contact lens
Muller & Obrig - 1938
designed and fitted glass corneal contact lenses
Eugène Kalt - 1940’s
first plastic corneal lens made from PMMA
Kevin Touhy - 1947
he developed HEMA
Otto Wichterle
•Describes the mechanism of image formation from the cornea to the optic nerve
Leonardo Da Vinci
•Attempted to show how various optical phenomena in myopes were corrected with spectacle glasses applied to the cornea
Philip De La Hire - 1685
- He understood that better vision could be achieved by enlarging the size of the retinal image, and that this could be achieved by elongating the antero-posterior axis of the eye.
- wrote ‘La Dioptrique’ in 1637
Rene Descartes - 1637
he used water-filled tube used to demonstrate the principle of the telescope by enlarging the retinal image
Rene Descartes
- Father of Contact Lenses
- an English astronomer, was interested in the correction of corneal astigmatism by a spectacle lens
John Herschel
He postulated the fitting of a spherical glass or jelly over the corneal surface, made from an impression of the cornea
John Herschel
was probably the first person to describe the concept of cosmetic lenses
John Herschel
•Recommended the insertion of a ‘glass mask’ filling the fornices, in order to prevent formation of symblepharon following lime burns of the eye
William White Cooper - 1859
•Possibly the first to suggest use of a therapeutic contact appliance
William White Cooper
•First person to apply a therapeutic contact device
Xavier Galexowski - 1886
- he covered corneal wounds with 0.25 - 0.50 mm thick gelatin squares which had been soaked in a solution of 0.25% mercuric chloride and 0.50% cocaine hydrochloride
- These plaquettes significantly reduced the level of infection
Xavier Galexowski - 1886
- he discussed the need for lens disinfection and the concept of adaptation to lens wear
- observed that corneal clouding did not occur as quickly if an air bubble was inserted behind his lens along with a 2% glucose solution
Adolf E Fick - 1888
- He devised the first contact lens for keratoconus
- wanted to remodel the corneal curvature by using glass contact shells as splints
Eugene Kalt - 1888
- used the term “Hornhautlinsen” or corneal lens
- noted that a steeper corneal radius needed a larger dioptric correction which he attributed to the lacrimal meniscus
August Muller - 1889
- Experienced and described subjective and objective signs of corneal edema
- Observed that tears had a metabolic function
August Muller
- He observed that corneal irregularity could be masked by filling the space between a scleral shell and the cornea with liquid having the same refractive index as the cornea and aqueous humor.
- This ‘fluid lens’ acted as an artificial refracting medium.
De Sulzer - 1892
First to replace the glucose solution used by Fick with normal saline
Henry H Dor
In an attempt to correct his bilateral keratoconic condition, He developed “water spectacles”
Thomas Lohnstein - 1896
he developed water spectacles
his contact device was also called a Hydrodiascope
Thomas Lohnstein
