Vitrectomy

Various factors threaten our eyesight and eye health. Ophthalmologists usually use different methods to treat visual impairment. The goal is to cure the illness and increase the quality of the individual's vision. One of these methods is vitrectomy.

 

* What is vitrectomy?

It is a type of eye surgery used to treat some retinal and vitreous disorders. The retina is a light-sensitive membrane covering the back of the eyeball. The vitreous body is the clear gel that fills the space between the lens and the retina of the eyeball. In the vitrectomy, the vitreous is removed and the surgeon replaces it with a special solution. this procedure is carried out in Tehran-Iran Noor Eye Hospital by the experienced ophthalmologists, using advanced equipment .

If any of the following symptoms is diagnosed in your eyes by your ophthalmologist, you are a candidate for a vitrectomy:

- Diabetic retinopathy, especially in case of retinal hemorrhage or traction

- Some cases of retinal detachment

- Intraocular infection

- Severe eye injury

- Macular pucker (central retina area)

- Macular hole

- Disorders after cataract surgery

Vitrectomy often improves vision or stabilizes it. Blood or residues of infections or inflammation that may obstruct or fade the image focusing on the retina are removed by this surgery.

Damaged tissue that may cause retinal displacement, wrinkles or detachment is removed by vitrectomy surgery. Vision decreases if the retina is not in its original location.

Vitrectomy can help remove foreign bodies trapped inside the eye after trauma. If these foreign bodies are not removed, they will often impair vision.

- Before vitrectomy

The ophthalmologist will decide on the preferred method of anesthesia, including local or general. You might be hospitalized for one night in Noor Eye Hospital, Tehran, Iran. Prior to surgery, the ophthalmologist might need to clinically examine the patient to assess particular medical conditions. To this end, the patient should be prepared. The staff of Tehran-Iran Noor Eye Hospital,  carefully guide such patients.

- At the time of vitrectomy

The duration of the vitrectomy varies from one to several hours depending on the patient's condition. In some situations, the ophthalmologist may use another surgical procedure simultaneously, including repairing a detached retina or removing the cloudy lens (cataract surgery).

This surgery is performed by a state-of-the-art ophthalmology microscope. Delicate surgical instruments are inserted into the eye by creating a small incision in the sclera or the white part of the eye.

 

In order to achieve the best possible vision for the patient, the ophthalmologist will perform one or more of the following:

1. Removing all the cloudy vitreous

2. Removing the damaged tissue and trying to bring the retina back to its original location

3. Remove foreign bodies that may have remained in the eye

4. Laser therapy to reduce the likelihood of future hemorrhage or to stabilize retinal detachment

5. Placing gas or air in the eye to help keep the retina in place

6. Placing silicone oil in the eye that usually requires subsequent surgery

In some cases, it is possible to use more delicate instruments for surgery. Using such equipment in operating rooms of Noor Eye Hospital, Tehran, Iran, patients will no longer need the stitches to repair the incision site. Furthermore, the operation will be shorter, and the pain and discomfort of the patient after surgery will be minimized.

- After vitrectomy surgery

Pain or discomfort is expected after surgery. It is recommended to use eye shield for a short time after surgery.The ophthalmologists of Tehran-Iran Noor Eye Hospital offer the patients special instructions about using the eye drops and determine the time when the patients can return to their daily activities.

Note: It is important to consider your ophthalmologist's postoperative recommendations. Furthermore, remind after surgery hold your head in the particular position that your physician determines,  because failure to do so can lead to treatment failure.

It is forbidden to fly or travel to high altitudes until the gas bubbles are dissipated because the rapid rise in height can lead to a dangerous increase in the eye pressure.

In cases where silicone oil is used, it is necessary to monitor the patient regularly and periodically, as silicone oil may cause problems over time and there might be a need for oil to be urgently removed.

The medical staff of Tehran-Iran Noor Eye Hospital will offer the patients useful postoperative recommendations.

All surgical procedures have complications, but vitrectomy has much fewer and rarer complications as compared with the benefits, which follow:

1. Infection

2. Bleeding

3. Retinal detachment

4. Reduced visual acuity

5. Increased eye pressure

6. Increased speed of cataract formation

Note: Although in rare cases, cataract progresses shortly after vitrectomy, it often progresses after a few months in older patients.

 

* Full recovery time after vitrectomy surgery

Visual acuity after the vitrectomy depends on several variables, especially in cases where ocular diseases have caused permanent damage to the retina before vitrectomy. The ophthalmologist will explain the likelihood of improving vision based on your conditions.

- What material is replaced in vitrectomy surgery after removing the vitreous?

- What material is replaced in vitrectomy surgery after removing the vitreous?

During this surgery, the vitreous is replaced by a BSS solution .

- My eye is damaged by a severe trauma. Will I be treated by a vitrectomy surgery?

For the best diagnosis and determination, an ophthalmologist of Tehran-Iran Noor Eye Hospital should examine your eyes, but it should be noted that a vitrectomy surgery can be used in case of severe eye injury.

- Is the vitrectomy surgery painful?

During surgery, the patient does not feel pain because of local or general anesthesia, but having pain or discomfort after a surgery is expected, which will be resolved by pain killers and other measures.

- Does gender affect vitrectomy surgery?

Typically, no, but the ophthalmologist may apply some measures based on the gender and the age of the patient for more accurate treatment.

- Can I go mountain climbing a week after the vitrectomy surgery?

It is forbidden to travel to high altitudes until the gas bubbles are dissipated because the rapid rise in height can lead to a dangerous increase in eye pressure.
