PATIENT NAME: Betty FOX
AGE: 72
SEX: Female
DOB: October 2
DATE OF CONSULTATION: August 5
CONSULTING PHYSICIAN: Brian Gates, MD, Ophthalmology

REASON FOR CONSULTATION: Cataracts

HISTORY: I saw Mrs. Fox, a 72-year-old, for her regular ______[Blank 1] examination. She has been wearing reading glasses for several years now but has noticed that she has been having trouble reading and has been seeing ______[Blank 2] around lights while driving at night.

PHYSICAL EXAMINATION: A visual ______[Blank 3] test was performed. I used a slit lamp to view the cornea, ______[Blank 4], lens, and the space between the iris and cornea. I detected tiny abnormalities. I administered drops to ______[Blank 5] the pupils to examine the retina. Using an ________[Blank 6], I was able to examine the lenses for signs of ______[Blank 7]. I was able to determine that Mrs. Fox has posterior _________[Blank 8] cataracts in both eyes.

PLAN: I explained to Mrs. Fox that she required cataract _________[Blank 9]. I explained that her clouded lens would be replaced with an _________[Blank 10] lens – a clear artificial lens. She was in agreeance to having the surgery. I told her we would perform the surgery on her right eye first, then in about eight weeks we would do the left eye. Arrangements for her surgery will be made for next month.
