Back 1

Trypan blue (already mixed for capsular staining)

Front 2

What is the most common single vision IOL used today?

Back 2

silicone (slippery when wet, high rebound energy)

Front 3

Which IOL material has the advantages of lack of capsular opacification, biocompatibility, with the ey;e (no inflam rexn from the eye), slow unfolding, high refractive index, thin, less pitting with YAG?d

Back 3

acrylic

Front 4

Can acrylic IOL's be used in patient with retinal pathology?

Back 4

Yes. (Acrylic: Tacky surface,less slippery when wet)

Front 5

Which IOL material requires slightly larger incision size?

Back 5

Hydrogel (Non-sticky surface + slow to unfold)

Front 6

Collamer (star ICL) is a combination of?

Back 6

silicone and collagen

Front 7

WHich IOL style (3 piece vs plate, has the advantage of the smallest possible incision size? What is their disadvantage?

Back 7

single-piece plate IOLs
disadvantage-rare fibrinoid reaction

Front 8

How many months do you have to wait before using a YAG laser on a single-piece plate IOL?

Back 8

3 months (a disadvantage for single-piece plate IOLs)

Front 9

What's the cataract post op visit schedule?

Back 9

1 day, 1 wk, 1 mo, 3 mo

Front 10

at the 24 hr post-op does a monofocal IOL require a BVA?

Back 10

yes

Front 11

at the 24 hr post-op does a multifocal IOL require a BVA?

Back 11

not necessary day 1

Front 12

At the 24 hr post op, you should expect some corneal edema with the scleral tunnel, should you expect corneal edema with CCI? What should you do?

Back 12

yes, there will be edema temporally, if the edema and stria are close to the line of sight, use muro 128

Front 13

What beam should you use to look for an anterior chamber reaction?

Back 13

don't use a conical beam, use a shrunken parallelpiped

Front 14

Grading AC reactions: If you see 10 cells at once what grade would you the AC?

Back 14

10 cells @ once 1+
20 cells @ once 2+
30 cells @ once 3+

Front 15

With what type of cataract are posterior capsule plaques more likely?

Back 15

PSC

Front 16

Should applanation tonometry be performed at the 24 hour post operative cataract visit?

Back 16

Yes, either Goldman or tonopen by the Dr.

Front 17

How high does the IOP have to be at the 24 hr post op cat sx before you bring it down in office and how do you do it?

Back 17

If IOP is >30mmHg bring down with two 250mg diamox

Front 18

Which dosage of diamox is used for chronic care and is a sustained release?

Back 18

500mg Diamox

Front 19

Why do you do BIO on the 24hr post op cat sx visit

Back 19

to ensure the retina and choroid are flat

Front 20

Why do we avoid using additional dilating drops to do bio on the 24 hr post op cat sx visit?

Back 20

a wide increase in dilation risks decentering the lens

Front 21

24 hr cat sx post-op: If the patient presents with severe AC reaction (3+ cells/flare) how should you change their steroid dosing schedule?

Back 21

Increase Pred forte to every 1-2 hours if severe inflammation

Front 22

24 hr cat sx post-op: When would you add a glaucoma medication

Back 22

If central corneal edema is present and IOP>22mmHg

Front 23

24 hr cat sx post-op: What do you do if your patient has a positive Seidel?

Back 23

pressure patch for 20 min while patient is reclined, then recheck. If resolved then recheck in 24 hours, if the patient is still leaking try pressure patch again or try a bandage contact lens

Front 24

When can a cat sx patient resume his blood thinner treatment?

Back 24

the day after the surgery

Front 25

Name two restrictions for the post op cat sx patient during the first 2 weeks after surgery?

Back 25

no eye makeup, and we want something on the eye during the day (either glasses, sunglasses, or the shield)

Front 26

Tell patient to call if RSVP. What does RSVP stand for?

Back 26

Redness, Sensitivity to light, vision decrease, and pain

Front 27

When should you do keratometry if it wasn't done at the 1 day post op visit?

Back 27

1 week post op visit

Front 28

If residual Anterior chamber reaction is present 1 week post op, when should you follow up with the patient again/

Back 28

follow up in 1-2 weeks if residual anterior chamber reaction

Front 29

Why do students need to make the staff doctor has looked at the anterior chamber before instilling fluorescein?

Back 29

Fluoroscein can mimic flare

Front 30

Post op cat sx: When is it ok to update the patients spec Rx?

Back 30

1 month post op

Front 31

Why do we perform DFE at 4-6 weeks post op?

Back 31

looking for CME

Front 32

Is 3 month post op cat sx visit needed if post op was fine?

Back 32

no

Front 33

A peaked pupil (comes to a point) is assumed to be what until proven otherwise? What do you do about it?

Back 33

Vitreal strand (use a YAG laser to lyse the strand) Broken posterior capsule then the vitreous comes forward (tends to go to the wound

What do you add to your treatment when central microcystic edema is present?

Back 34

muro, 5% NaCl solution qid + ung QHS + PF q2hrs

Front 35

Which laser should be used to treat recurrent hyphema?

Back 35

Argon laser of abnormal blood vessel on gonio. Use steroids to decrease inflammation
