|
Trypan blue (already mixed for capsular staining)
|
|
What is the most common single vision IOL used today?
|
silicone (slippery when wet, high rebound energy)
|
|
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
|
acrylic
|
|
Can acrylic IOL's be used in patient with retinal pathology?
|
Yes. (Acrylic: Tacky surface,less slippery when wet)
|
|
Which IOL material requires slightly larger incision size?
|
Hydrogel (Non-sticky surface + slow to unfold)
|
|
Collamer (star ICL) is a combination of?
|
silicone and collagen
|
|
WHich IOL style (3 piece vs plate, has the advantage of the smallest possible incision size? What is their disadvantage?
|
single-piece plate IOLs
disadvantage-rare fibrinoid reaction |
|
How many months do you have to wait before using a YAG laser on a single-piece plate IOL?
|
3 months (a disadvantage for single-piece plate IOLs)
|
|
What's the cataract post op visit schedule?
|
1 day, 1 wk, 1 mo, 3 mo
|
|
at the 24 hr post-op does a monofocal IOL require a BVA?
|
yes
|
|
at the 24 hr post-op does a multifocal IOL require a BVA?
|
not necessary day 1
|
|
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?
|
yes, there will be edema temporally, if the edema and stria are close to the line of sight, use muro 128
|
|
What beam should you use to look for an anterior chamber reaction?
|
don't use a conical beam, use a shrunken parallelpiped
|
|
Grading AC reactions: If you see 10 cells at once what grade would you the AC?
|
10 cells @ once 1+
20 cells @ once 2+ 30 cells @ once 3+ |
|
With what type of cataract are posterior capsule plaques more likely?
|
PSC
|
|
Should applanation tonometry be performed at the 24 hour post operative cataract visit?
|
Yes, either Goldman or tonopen by the Dr.
|
|
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?
|
If IOP is >30mmHg bring down with two 250mg diamox
|
|
Which dosage of diamox is used for chronic care and is a sustained release?
|
500mg Diamox
|
|
Why do you do BIO on the 24hr post op cat sx visit
|
to ensure the retina and choroid are flat
|
|
Why do we avoid using additional dilating drops to do bio on the 24 hr post op cat sx visit?
|
a wide increase in dilation risks decentering the lens
|
|
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?
|
Increase Pred forte to every 1-2 hours if severe inflammation
|
|
24 hr cat sx post-op: When would you add a glaucoma medication
|
If central corneal edema is present and IOP>22mmHg
|
|
24 hr cat sx post-op: What do you do if your patient has a positive Seidel?
|
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
|
|
When can a cat sx patient resume his blood thinner treatment?
|
the day after the surgery
|
|
Name two restrictions for the post op cat sx patient during the first 2 weeks after surgery?
|
no eye makeup, and we want something on the eye during the day (either glasses, sunglasses, or the shield)
|
|
Tell patient to call if RSVP. What does RSVP stand for?
|
Redness, Sensitivity to light, vision decrease, and pain
|
|
When should you do keratometry if it wasn't done at the 1 day post op visit?
|
1 week post op visit
|
|
If residual Anterior chamber reaction is present 1 week post op, when should you follow up with the patient again/
|
follow up in 1-2 weeks if residual anterior chamber reaction
|
|
Why do students need to make the staff doctor has looked at the anterior chamber before instilling fluorescein?
|
Fluoroscein can mimic flare
|
|

|
1 month post op
|
|
Why do we perform DFE at 4-6 weeks post op?
|
looking for CME
|
|

|
no
|
|
A peaked pupil (comes to a point) is assumed to be what until proven otherwise? What do you do about it?
|
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?
|
muro, 5% NaCl solution qid + ung QHS + PF q2hrs
|
|
