2.

What is the symptom for cataract?
- Cloudy or blurry vision
- Poor night vision
- Colors seem faded
- All of them
Correct Answer

A. All of them

Explanation

Cataract is a condition characterized by the clouding of the lens in the eye, resulting in vision impairment. The symptoms of cataract include cloudy or blurry vision, poor night vision, and colors appearing faded. Therefore, all of the given options are symptoms of cataract.

3.

Which of these cataracts is really a cataract?
- Secondary cataract
- All of them
- Congenital cataract
- Traumatic cataract
Correct Answer

A. All of them

Explanation

The correct answer is "All of them" because all of the options listed are types of cataracts. A cataract is a clouding of the lens in the eye, which can cause blurry vision and eventually lead to vision loss. Secondary cataract refers to a cataract that develops after surgery for another eye condition. Congenital cataract is a cataract that is present at birth or develops during infancy. Traumatic cataract is a cataract that occurs as a result of an eye injury or trauma. Therefore, all of these options are types of cataracts.

4.

What is usually implanted into the eye after the removal of the cataract?
- Intraocular lens
- New eye lens
- Nothing
- Liquid lens
Correct Answer

A. Intraocular lens

Explanation

After the removal of a cataract, an intraocular lens (IOL) is usually implanted into the eye. This is a synthetic lens that replaces the natural lens of the eye, which has been clouded by the cataract. The IOL helps to restore clear vision by focusing light onto the retina. It is a common procedure in cataract surgery and allows individuals to regain their visual acuity and reduce the need for glasses or contact lenses.

5.

Under what anesthesia are most cataracts operated?
- General Anesthesia
- Local Anesthesia
- Without Anesthesia
- Combined General and Epidural Anesthesia
Correct Answer

A. Local Anesthesia

Explanation

Most cataract surgeries are performed under local anesthesia. This type of anesthesia involves numbing the eye area with eye drops or an injection. It allows the patient to remain awake during the procedure while ensuring that they do not feel any pain. Local anesthesia is preferred for cataract surgeries as it is considered safe and effective, with fewer risks compared to general anesthesia. Additionally, it allows for a faster recovery time and reduces the need for post-operative monitoring.

6.

What is the safest and most common technique for removing cataracts?
- Manual small incision cataract surgery
- Phacoemulsification
- Extracapsular cataract extraction
- Intracapsular cataract extraction
Correct Answer

A. Phacoemulsification

Explanation

Phacoemulsification is the safest and most common technique for removing cataracts. It involves using ultrasound energy to break up the cloudy lens, which is then suctioned out through a small incision. This technique is preferred because it requires a smaller incision, results in faster recovery, and has a lower risk of complications compared to other methods such as extracapsular or intracapsular cataract extraction.

Rate this question:
7.

How long does the procedure (Phacoemulsification) last?
- 4 hours
- 2 hours
- 5 - 10 minutes
- 20 - 30 minutes
Correct Answer

A. 20 - 30 minutes

Explanation

The correct answer is 20 - 30 minutes. Phacoemulsification is a surgical procedure used to remove cataracts from the eye. During the procedure, an ultrasonic device is used to break up the cloudy lens and remove it. The entire process typically takes between 20 to 30 minutes, making it a relatively quick and efficient procedure.

Rate this question:
8.

How long is the typical cataract surgery recovery time?
- 1 month
- 2 month
- 1 week
- 2 weeks
Correct Answer

A. 1 month

Explanation

The typical cataract surgery recovery time is usually around 1 month. This is because after the surgery, it takes time for the eye to heal and for the vision to fully stabilize. During this recovery period, patients may experience blurry vision, sensitivity to light, and mild discomfort. It is important for patients to follow post-operative instructions, use prescribed eye drops, and avoid strenuous activities to ensure a smooth recovery.

9.

What was the favored form of cataract extraction from the late 1960s to the early 1980s?
- Phacoemulsification
- Extracapsular cataract extraction
- Intracapsular cataract extraction
- Cryoextraction
Correct Answer

A. Cryoextraction

Explanation

Cryoextraction was the favored form of cataract extraction from the late 1960s to the early 1980s. This technique involved freezing the lens using a cryoprobe and then extracting it from the eye. It was a popular method during that time period due to its effectiveness and relatively low complication rates. However, with advancements in technology, phacoemulsification became the preferred method of cataract extraction in the following years.

What is "Manual small incision Cataract surgery"?
- Surgery that involves the removal of the lens and the surrounding lens capsule in one piece
- Surgery that involves the removal of almost the entire natural lens while the elastic lens capsule is left intact
- Surgery where the entire lens is expressed out of the eye through a self-sealing scleral tunnel wound
- Surgery that involves the use of a machine with an ultrasonic handpiece equipped with a titanium or steel tip
Correct Answer

A. Surgery where the entire lens is expressed out of the eye through a self-sealing scleral tunnel wound

Explanation

Manual small incision cataract surgery is a surgical procedure where the entire lens is removed from the eye through a self-sealing scleral tunnel wound. This technique involves making a small incision in the eye and manually expressing the lens out of the eye. It is a minimally invasive procedure that allows for a faster recovery and reduced risk of complications compared to other surgical techniques.
