Yung jie (F/68) came for eye examination, she had cataract surgery in left eye 3months ago. . right eye was done 2years ago. She reported feeling something poking at the top of her right eyelid.. and sometimes feeling tired eyes. She sees perfectly fine far, and she does not see phone that much.

Vision without glasses
R: 6/6-
L: 6/9-

Subjective Refraction
R: +0.25 (6/6) (+1.00 blur test: 6/9)
L: -0.25 (6/6) (+1.00 blur test: 6/9)
Add: +2.25

Other assessments show:

Cover Test
Distance: NMD
Near: NMD

Howell Card
Distance: 0 – 1 EP
Near: 4 – 6 XP
-1.00 Near: 2 – 4 XP

NRA
+0.50

PRA
-0.75

NPC

Fusional Reserves
Near, PFV: x/30/20
Near, NFV: x/8/6
Distance, NFV: x/6/4
Distance, PFV: x/14/12

Vergence Facility
Near: 11 cpm
Distance: 4 cpm (slow BO & BI)

Interpupillary distance, IPD = 5.9cm

Fluorescein
R: -ve staining
L: -ve staining

Slit Lamp
R: normal
L: nasal pterygium

TBUT
R: 3s
L: 3s

Pterygium = whitish growth that grows onto cornea(front part of our eye)
We everted her right eyelid.. very mild concretion(yellowish dots)

Yung jie sometimes sees her phone without wearing glasses. We remind her to wear her reading glasses to see near so that her eyes will feel more comfortable.
