Transcript of Cataract Surgery

Cataract Surgery
One of the most common surgeries in the United States.
3,000,000 surgeries are performed each year.
A cataract can be compared to a dirty camera lens.
A cataract occurs when the lens of the eye becomes cloudy and causes sight issues.
The operation takes about 15-30 minutes. After the surgery, the patient must stay in the hospital for 3-4 hours and have another person there to transport them home.
An ophthalmologist will perform the surgery in the operating room of a hospital.
Standard ECCE
1. An 8-10 mm incision is made where the cornea and sclera.
2. Another incision is made in the lens capsule.
3. The lens is removed along with any other lens material.
4. An IOL is placed inside the lens capsule.
1. Two small incisions are made where the sclera and the cornea meet.
2. An opening is created on the surface of the lens.
3. A phaco probe is inserted into the eye.
4. Sound waves are used to break the cataract into small piece. The lens and cataract pieces are then sucked out of the eye.
5. Finally an IOL is placed in the lens capsule.

Objectives, Reasons, and Risks
Alyssa Shafor
There are two types of surgeries: phacoemulsification and standard extracapsular cataract extraction (ECCE).
Most surgeries are done using either a topical anesthetic (eye drops) or local anesthetic, which involves a sedative and then an injection around the eye to deaden the nerves and prevent blinking.
General anesthetic would have to used under certain circumstances:
People with uncontrollable anxiety
People who are unable to follow directions during surgery
People with allergies to local anesthetics
People with other medical conditions
Swelling: corneal edema
Retinal detachment: Nerve layer detaches from the back of the eye
Problems with glare
Dislocated intraocular lens
Sagging of upper eyelid
