What Is Trabeculoplasty?

Glaucoma laser surgery is an advanced technology for glaucoma treatment. It is a powerful beam with a small spot size. Depending on the intensity of the beam, it can cause small burning or penetration of eye tissue. The light beam passes through the layers of the eye and is accurately focused on the treatment position of the eye. Laser can be used for peripheral iris resection, that is, iris drainage port. It is one of the methods to treat angle-closure glaucoma. The laser is also used to open the drainage tube of some eyes, such as the opening of the filter curtain, which is suitable for open-angle glaucoma.

The principle of glaucoma surgery : filtering surgery (commonly used trabeculectomy, subscleral bite, iris-embedded sclera, and scleral burn filtration): the purpose is to establish new extraocular drainage. Suitable for patients with chronic angle-closure glaucoma with extensive adhesions in the atrial angle, and inability to control intraocular pressure with the use of pupil shrinkage agents, C value <0.11; patients with chronic angle-open glaucoma drugs ineffective;

Precautions

In the treatment of glaucoma, surgery is an important treatment method. The basic principle is to establish a new path to open the obstruction, and the purpose is to reduce intraocular pressure and protect visual function. Most glaucoma patients require surgical treatment to achieve the goal of cure. After the operation, care must be strengthened to avoid recurrence and achieve the expected goals. The following 5 points should be taken seriously by patients.

1. Avoid postoperative bleeding.

Bandaged eyes rest in bed for 1-2 days after surgery. During this period, reduce activity, especially to avoid excessive head movement. If there is a cough or sputum, treat it symptomatically to prevent the cough or violent activity from pulling the wound, which will cause wound bleeding and affect healing.

2. Stay optimistic.

During bed rest, you can listen to light music and chat with relatives or patients to prevent depression and depression. After being able to go down to the ground, you can take a walk or play Tai Chi to stretch your emotions. Do not argue with others to prevent emotional excitement and relapse.

3. Reasonably adjust your diet.

Eat foods that are easy to digest, light, and nutritious to ensure nutrient supply and improve tissue repair. Eat more fiber-rich foods such as fruits and vegetables to keep your stools open. Avoid irritating foods, tobacco, alcohol, coffee, etc.

4. Pay attention to lifestyle.

After leaving the wound, we should pay attention to developing a good lifestyle such as regular life, moderate work and rest, and adequate sleep. Pay attention to drinking a small amount of water many times on weekdays, not drinking a large amount of water or drinking strong tea at one time, so as not to affect the normal adjustment of intraocular pressure.

5. Strengthen eye hygiene.

Do not read for a long time or stay in the dark for too long. The indoor light should be appropriate to prevent it from being too strong or too dark. Always stick to massage.

Precautions after glaucoma laser surgery

1. Follow the doctor's orders to take the medicine on time and avoid random addition and subtraction, thereby reducing excessive fluctuations in intraocular pressure and side effects of the surgery.

2. Regular outpatient review, the main inspections include: vision, routine eye examination, intraocular pressure, shape and color of the optic nerve, visual field and angle of the room.

3. Due to the unsatisfactory control of intraocular pressure in some patients after surgery, long-term eye drops and surgical treatment are needed to prevent further damage to visual function.

4. Some patients who underwent iris radical surgery or outpatient laser iris surgery and non-penetrating trabeculotomy, if the intraocular pressure needs to be re-operated, trabeculectomy is often required.

5. For patients who have undergone trabeculectomy, if the intraocular pressure increases and need to be operated again, you can take trabeculectomy again and use mitomycin and other drugs to prevent recurrence during the operation.

6. For patients with multiple surgeries, if the intraocular pressure needs to be re-operated, it is often necessary to take the ciliary body cryosurgery, the ciliary body laser photocoagulation surgery, or the vitrectomy combined with the intraocular ciliary body laser photocoagulation surgery.

7. For glaucoma patients with cataract, if anti-glaucoma surgery is needed, if cataract has severely affected vision, cataract glaucoma artificial lens (triple) surgery can be combined.

8. For the refractory glaucoma that has failed the anti-glaucoma operation and the vision has preservation value, if the combined drug cannot control the ideal intraocular pressure, a glaucoma valve implantation operation can be used.
