(Cataract Extraction) The preferred procedure, where just the lens is removed, is called what?

extracapsular cataract extraction

What is tonometry?

measurement of pressure in the anterior chamber of the eye

Chronic open angle glaucoma develops over time and is

painless

Medical Treatment Cataracts:

removal of the lens

Signs and Symptoms Cataract include:

-cloudy vision -seeing spots or ghost images and floaters

S/S of Retinal Detachment

-flashes of lights or floaters -vision may be cloudy -if area of detachment is large, vision may be lost completely -*pt may say it feels as if a curtain has come down across the line of vision*

What are the (3)complications of cataract surgery?

-leakage of vitreous humor -hemorrhage into the eye -opening of the incision

Cataracts Pathophysiology

-lens may become opaque(white) quickly or slowly -injuries tend to cause opacity rapidly, whereas age-related progresses slowly -blindness occurs if a cataract is untreated
