Explanation of Solution

1. Phacoemulsification with IOL; OS - I. Cataracts. It is the clouding of lens in the eye that leads to poor vision. The treatment used to treat cataract us phacoemusldification.

2. Blepharoplasty - B. ptosis of eyelid skin. Blepharitis is the swelling, reddening, and crusting of eyelid. The removal of this eyelid skin is blepharoplasty.

3. Scleral buckle - C. retinal detachment. Deterioration of retinal layer is called retinal detachment. The treatment called scleral buckling is sued to treat and repair retinal detachment.

4. Vitrectomy - D. diabetic retinopathy. Vitrectomy is the surgical removal of vitreous humor that is caused by diabetic retinopathy.

5. Radical mastoidectomy - G. chronic infection of a bone behind the ear. It is the surgical procedure to remove the posterior region of ear canal to create a common cavity for the mastoid and ear canal.

6. Keratoplasty - A. scarred and torn cornea. Keratoplasty is procedure to replace the corneal tissue.

7. Cochlear implant: H. severe deafness. Sensorineural hearing loss can be treated by cochlear implant which is a device that replaces the function of inner damaged ear.

8. Laser photocoagulation of the macula - E. macular degeneration. The macular degeneration causes blurred vision in the visual field. This is mainly due to the abnormal blood vessels that leaks the fluid or blood in the macula. It is treated by laser photocoagulation. It is a surgery which uses light to coagulate that shrink or destroy abnormal blood vessels in the retina.

9. Incision and drainage of hordeolum - F. chronic stye. Hordeolum is the stye that occur due to the bacterial infection of an oil gland in the eyelid. This leads to the red bump at the edge of the eyelid. It may affect both the inner and outside of the eyelid.
