Answer 10

Philip De La Hire - 1685

Question 11

• 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

Answer 11

Rene Descartes - 1637

Question 12

he used water-filled tube used to demonstrate the principle of the telescope by enlarging the retinal image

Answer 12

Rene Descartes

Question 13

• Father of Contact Lenses
• an English astronomer, was interested in the correction of corneal astigmatism by a spectacle lens

Answer 13

John Herschel

Question 14

He postulated the fitting of a spherical glass or jelly over the corneal surface, made from an impression of the cornea

Answer 14

John Herschel

Question 15

was probably the first person to describe the concept of cosmetic lenses

Answer 15

John Herschel

Question 16

•Recommended the insertion of a ‘glass mask’ filling the fornices, in order to prevent formation of symblepharon following lime burns of the eye

Answer 16

William White Cooper - 1859

Question 17

•Possibly the first to suggest use of a therapeutic contact appliance

Answer 17

William White Cooper

Question 18

•First person to apply a therapeutic contact device

Answer 18

Xavier Galexowski - 1886

Question 19

• 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

Answer 19

Xavier Galexowski - 1886

Question 20

• 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

Answer 20

Adolf E Fick - 1888

Question 21

• He devised the first contact lens for keratoconus
• wanted to remodel the corneal curvature by using glass contact shells as splints

Answer 21

Eugene Kalt - 1888

Question 22

• 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

Answer 22

August Muller - 1889

Question 23

• Experienced and described subjective and objective signs of corneal edema
• Observed that tears had a metabolic function

Answer 23

August Muller

Question 24

• 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.

Answer 24

De Sulzer - 1892

Thomas Lohnstein - 1896

Question 27

he developed water spectacles

his contact device was also called a Hydrodiascope
