Ed, a 45-year-old man, goes to the doctor complaining of severe ear pain and reduced hearing. He has a cold, and remarks that he disembarked from an international flight the day before. The physician prescribes a decongestant and tells Ed to take an audiology test if his hearing is not improved when his cold is better. Ed also states that he can no longer see small print clearly, even though he has never been nearsighted and his distance vision and ability to drive are not impaired. He asks if surgery might correct this. Which condition was responsible for Ed's visual impairment? Would LASIK be able to help Ed? What kind of glasses does Ed need?
