Question
Susan, a 28-year-old woman, was experiencing a ringing in her ears, hearing loss, and an occasional feeling that the room was spinning. She went to a specialist and, after ruling out otitis media and Meniere's disease, was told that she had otosclerosis. The specialist said that she would need a hearing aid and likely surgery. After leaving this physician, she went to an optometrist who told her that she needed new glasses for her myopia, or alternatively she could go in for LASIK surgery. Susan laughed ruefully and agreed to seek that procedure.
Some of the new terms and concepts you will encounter include:
Middle-ear and inner-ear structures involved in hearing and equilibrium
Eye structure and function in focusing and vision

Explanation / Answer
Medical terms first of all for middle ear are the ear ossicles ( Malleus ,Incus and Stapes)
Inner ear - Vestibule , Semicircular canals , Cochlea , Utricle and Saccule
Vision - Cornea and lens
Focus and image formation - Retina
Ringing in ears - Tinnitus
Inner ear is mainly affected in otosclerosis .
It is defined as primary disease of bony labyrinth in which one or more foci of irregularly laid spongy bone replace part of normally dense endochondral bone.
It impairs hearing by Stapes fixation resulting in loss of transmission of sound to the oval window .
Hearing loss is bilateral conductive hearing loss .
Hearing aid or prosthesis like Teflon piston can be used to between oval window and Incus .
For myopia we need concave glasses or divergent lenses.
LASIK - Laser assisted in situ keratomileusis
It helps in correction of refractive error by altering the curvature of cornea .
