Cataracts
Types of Surgery
Intracapsular
Remove entire lens
Not used much anymore
Extracapsular
98% done this way
Remove anterior capsule and lens
Leave posterior capsule
Place plastic lens

Hearing Loss
Conductive-decreased or absenttransmission of sound from external
auditory canal to and through the middleear.
Causes
Impacted cerumen
Loss of elasticity of tympanic membrane
Bone rigidity-otosclerosis

Sensorineural-gradual hearing loss inelder. Presbycusis in elder. Damage tothe inner ear, auditory nerve, brainstemand/or cortical-auditory pathways.
Causes
Noise damage
Aging
Drug toxicity (ototoxicity)

Hearing Loss
Management
Prevention in the first place!
Health problems can go untreated due to hearing loss.
Make whatever accommodations are neededSign language
Think about it: You are elderly and ill. You are in a
strange place having strangers do strange things to yourbody. The room is darkened and they are wearingmasks. You cant hear or understand what they are
saying. Would you feel comfortable?
