12. A topical anesthetic.






13. Right eye (OD)






14. Inward






15. Provide a bigger field of vision.






16. The instrument that contains lenses and can be used to determine a spectacle correction.






17. 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.






18. Outward






19. Surgical removal of the lens - usually replaced with a plastic intraocular lens.






20. A test that allows a doctor to see inside the back of the eye and other structures using a magnifying instrument and a light source.






21. A test that measures the pressure inside your eye - which is called intraocular pressure.






22. The chart most often used to measure acuity at distance.






23. Dilators






24. The entire area that can be seen when the eye is directed forward including that which is seen with peripheral vision.






25. The creation of a photograph of the interior surface of the eye.






26. 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.






27. As needed






28. When the vision in one of the eyes is reduced because the eye and the brain aren't working together properly. The eye itself may look normal - but it's not being used normally because the brain is favoring the other eye.






29. Involves an imbalance in the positionig of the two eyes. I can cause the eys to cross in or tuyrn out. It's cause by a lack of coordination between the eyes.






30. Every _ Hour






31. This is the pathway between the ye and the brain along which the signals produced by the retina travel to the brain.






32. The result of the refraction depends on the patient's ability to discern changes in clarity. This process relies on the cooperation of the Patient.

34. The distance from the back surface of the lens to the front of the eye.






35. Provides nutrients for the lens and posterior cornea.






36. Which type of lens will have the same power in all areas of the lens?

38. What are plus lenses used to correct?






39. A lens with no power.






40. The portion of the optic nerve that is formed by the meeting of all retinal nerve fibers.






41. Corrects one eye for distance and the other eye for near and can be used to correct presbyopia.






42. Layers in the cornea






43. Upward and diagonally






44. A paralysis of the ciliary muscle - so accommodation can't occur.






45. Increases visual acuity because it reduces internal lens reflections.






46. Controls the focusing power of the eye by changing the shape of the lens.






47. What does a tonometer measure?






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






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






50. Located behind the pupil - and is the secondary mechanism of focus - adjusting the amount of focus the light image requires before it reaches the retina.
