Term
What are symptoms of a cataract
Definition
Brownish/yellow hue - Monet

Glare/Halos

Overall unclear vision -especially in low light

Cataracts are removed when they limit the patients quality of vision
Term
What is ECCE
Definition
Extraoccular capsular extraction (most common)

Removal of lens without removing the bag for an intra-occular implant (IOL)
Term
What is ICCE
Definition
Intraoccular capsular extraction

Removal of the lens with the bag

Removing the bag removes possibility of having an implant
Term
With ECCE when you remove the crystalline lens what do you also stop
Definition
The patients ability to accommodate
Term
What does IOL stand for
Definition
Intra-occular implant
Term
With ECCE the implants can be
Definition
Single vision or Multi focal

MF is more expensive

Most patients will opt in for single vision
Term
With ECCE their is a how many week gap between surgeries
Definition
2 weeks

One eye done 2 weeks then the other eye
Term
With ICCE means removal of the lens without implant that means the eye will be
Definition
14 diopters weaker
Term
With ICCE the patient will require a strong
Definition
Plus lenses to correct
Term
It is important that with ICCE patients
Definition
They need UV protection
Term
One of the main differences with ICCE patients and ECCE patients is
Definition
ICCE needs UV protection because we removed the lens

BIG CONCERN
Term
Because one eye is done one at a time during surgeries

You may see the doctor prescribe a RX and may offer
Definition
A balanced lens
Term
What is a balanced lens
Definition
It tells us that patient has no or limited vision on that side that still has a cataract in it

The goal is to blur out vision on one side so they can enjoy the side that had the surgery and it's very clear
Term
Frosting lens means
Definition
Covering that one lens that still has the cataracts with something to blur the vision

Nail polish

Scotch tape

Only focus on seeing the one good eye
Term
Post cataract expectations
Definition
Sudden improvement in clarity of vision

Colors are brighter

Less glare (with or without implant)

Pt with IOL may see glare halo but it goes away over time
Term
What does Aphake mean
Definition
Someone without a lens
Term
How do we make up for the loss of the 14 diopter lens
Definition
Glasses more than likely

Vertex distance is correct and the panto is correct based on how the frame fits the patient

11-13 mm just clearing the lashes vertex distance usually
Term
When fitting an Aphake what should come into play when picking frames
Definition
Frame choice

Smaller eye size

Round in shape

Adjustable pads to center eyes in frame and control vertex

Longer temples to support weight

Possible dark frame option to help mitigate oblique light

Term
For an Aphake what are the benefits of a close VX are
Definition
Wider field of view in segment

Less magnification of the eyes

Smaller retinal image size (RIS)
Term
What is a lenticular design
Definition
FRIED EGG

30-40 mm of optics on a plano carrier

Cheap (covered by medicare)

Higher decentration - may allow for free frame selection
Term
What is a full field design
Definition
Wider field of view

More cosmetically pleasing than lenticular

Thinner/lighter (relatively)

Causes less magnification of the pt eyes
Term
Good option for a full field lenses are
Definition
FT22 x 11

ZERO BTS
