Lens and Cataract: Evaluation and Management

Question 0

nuclear

Answer 0

this cataract has no impact on near vision

Question 1

nuclear

Answer 1

this cataract has the greatest effect on distance vision

Question 2

cortical

Answer 2

this cataract has a mild impact on near and distance vision

Question 3

PSC

Answer 3

this cataract has a mild effect on far vision but a marked effect on near vision

Question 4

increased glare

Answer 4

optical risk of dilation therapy for small axial cataracts

Question 5

alpha-1a blockers

Answer 5

medication class associated with IFIS

Question 6

RLS, head tremor

Answer 6

movement problems that should be explored before cataract surgery (may change type of anesthesia)

Question 7

posterior capsule disruption

Answer 7

prior vitrectomy increases the risk of this during cataract surgery

Question 8

posterior polar opacity

Answer 8

this congenital anomaly poses a significantly increased risk of intraoperative posterior capsular disruption

Question 9

+10 D

Answer 9

when using the direct ophthalmoscope at distance (2 ft) for evaluation of cataracts, this lens should be used

Question 10

20/200

Answer 10

PAP is done in eyes with acuity better than this

Question 11

0.3 mm

Answer 11

an unexplained difference in preoperative axial length measurements should be no greater than this

Question 12

applanation, immersion

Answer 12

two types of A-scan ultrasonography

Question 13

1.5

Answer 13

approximate relative transit speed of silicone oil versus vitreous

Question 14

optical biometer

Answer 14

what kind of device is the IOLMaster

Question 15

A constant

Answer 15

manufacturer-specified value that relates lens power and keratometry to axial length

Question 16

0.2 mm

Answer 16

upward limit of variance for A scan values in IOL calculations
