Answer:
It is very likely that the condition of Ellis, being applied a phacoemulsification, is due to cataracts.
Step-by-step explanation:
Phacoemulsification is a surgical procedure used in orphthalmology for the corrective treatment of cataracts.
Cataract is a condition —for which Ellis consulted the ophthalmologist— in which the eye's crystalline lens, located in the anterior chamber, becomes opaque and rigid, preventing normal vision by scattering the images and light it receives.
With phacoemulsification the crystalline lens is dissolved and removed, to be replaced by a special solution or a soft and flexible lens. It is an alternative to traditional surgery, where the crystalline lens is replaced by an intraocular lens.
The other options are not correct because:
- Vertigo and tinnitus are disorders more related to the ear, and not to the sight, requiring the attention of an otolaryngologist.
- Conjunctivitis is an inflammatory or infectious disease of the ocular conjunctiva, which does not require phacoemulsification.
