ND:YAG Laser Capsulotomy

ND:YAG Laser Capsulotomy is a procedure that uses a laser to treat clouding of the lens capsule, a thin, clear membrane that surrounds the natural lens of the eye. Clouding of the lens capsule, also known as posterior capsule opacification (PCO), is a common complication of cataract surgery, a procedure to remove the natural lens of the eye and replace it with an artificial lens. PCO occurs when cells from the inner lining of the lens capsule grow and multiply, creating a cloudy area that can interfere with vision.

RETINA SURGERY TYPES

Here is a general overview of the steps involved in ND:YAG laser capsulotomy:

• Preparation: Before the procedure, the ophthalmologist will perform a thorough eye exam to assess the degree of clouding and determine the best approach. The ophthalmologist will also discuss the risks and benefits of the procedure with the patient and obtain their informed consent.
• Anaesthesia: Nd:YAG laser capsulotomy is usually performed using local anaesthesia, which numbs the eye and surrounding area. The ophthalmologist may also use a sedative to help the patient relax.
• Laser treatment: The ophthalmologist will use a specialized laser called a Nd-YAG laser to make a small, circular opening in the centre of the cloudy lens capsule. The laser is carefully aimed and controlled to minimize the risk of damage to the surrounding tissue.
• Closure: The procedure is usually completed in a few minutes and does not require any suture closure. The ophthalmologist may place a protective shield over the eye to prevent the patient from rubbing or touching the surgical site.
• Recovery: After the procedure, the patient will be given instructions on how to care for the eye and manage any discomfort or swelling. The ophthalmologist will also schedule follow-up visits to monitor the patient’s progress and address any concerns.

It’s important to note that ND:YAG laser capsulotomy is a relatively quick and straightforward procedure, but it’s important to follow the ophthalmologist’s instructions for care and follow-up to ensure the best possible outcome.

SYMPTOMS

If you have had cataract surgery and are experiencing any of the following symptoms, you may need an ND-YAG laser capsulotomy:

• Blurred vision: If your vision is blurry after cataract surgery, it may be due to posterior capsule opacification (PCO). PCO is a condition in which the capsule surrounding the artificial lens becomes cloudy or opaque, which can cause vision to become blurry or distorted.
• Glare or halos around lights: If you notice glare or halos around lights, it may be a sign that the capsule surrounding your artificial lens is becoming cloudy. This can cause light to scatter as it enters your eye, resulting in glare or halos.
• Decreased contrast sensitivity: If you have trouble distinguishing between similar shades of colour or find it difficult to see objects against a complex background, you may have decreased contrast sensitivity. This can be a symptom of PCO and may indicate a need for Nd:YAG laser capsulotomy.
• Difficulty reading: If you are having trouble reading small print or seeing objects up close, it may be due to PCO. The cloudy capsule can interfere with your ability to focus on nearby objects, making it difficult to read or see details.
• Poor vision at night: If you have trouble seeing at night or in low-light conditions after cataract surgery, it could be a sign of PCO. The cloudy capsule can cause glare and haloes around lights, which can make it difficult to see at night or in dimly lit environments.
