1
Q
Lens of the eye
A
Responsible for focusing images onto the back of the eye. Normally transparent
2
Q
Cataract
A
As a normal part of aging, the lens begins to cloud and causes a gradual, painless loss in vision
3
Q
Why might cataract removal be performed?
A
To better examine the back of the eye when monitoring for damage from certain diseases such as diabetes or glaucoma and to improve vision
4
Q
Two types of cataract removal
A
- Phacoemulsification
- Extracapsular Technique
5
Q
Phacoemulsification
A
- Majority of cataract surgeries
- Ultrasound probe breaks the cloudy lens into tiny fragments
- Fragments are vacuumed out through a tiny incision
- Intraocular lens implant is then inserted to replace the natrual lens that was removed
- Stitches are often not necessary and visual improvement is usually noted relatively soon after surgery
- Patch over the eye
6
Q
Extracapsular Technique
A
- Cataract is removed as one entire piece
- Larger incision and stitches
- Intraocular lens implant (artificial lens) is inserted to replace the natural lens that was removed
- Recovery is slower, due to larger incision
- Stitches sometimes need to be removed
- Patch over the eye
