11. A mid-index lens material that is thinner than glass or CR-39 - free from distortion and aberration and able to be used as a safety lens.

21. Measurement of the form and curvature of the cornea.






22. Proparacaine - Tetracaine - Cocaine






23. Numerous different surgeries that facilitate the escape of excess aqueous humor from the eye to lower the intraocular pressure and a few that lower IOP by decreasing the production of aqueous humor.






24. Upward and diagonally






25. What lens material is the easiest to break?






26. The Optothalmic examination of the eye by use of a slit lamp and a magnifying lens.






27. The nerve center of the eye where light is converted into an electrical signal that travels along the optic nerve to the brain.

37. The smallest unit of lens measure.






38. The procedure using ultraviolet radiation from a laser to remove tissue.






39. A group of diseases that can damage the eye's optic nerve and result in the vision loss and blindness. It occurs when the normal fluid pressure inside the eyes slowly rises.

48. Refers to imaging by section or sectioning - through the use of any kind of penetrating wave.






49. The ability to maintain visual focus on an object with both eyes creating a single visual image.






50. The gel that fills the eye and allows it to maintain its shape. Also serves as a clear pathway for light when it travels from the lens to the retina.
