What is involved in retinal surgery?

When you get this surgery, your doctor will: Put numbing medicine in your eye. Insert a tiny needle into your eye and remove a small amount of fluid. Inject a small amount of air into your eye. Use laser or freeze treatment to repair any holes or tears in your retina.

What is deep Sclerotomy?

Deep sclerectomy is one type of glaucoma operation. The operation may be performed on its own or can be combined with surgery to remove a cataract. In deep sclerectomy a filtering membrane is created for fluid to move out of the front chamber of the eye to underneath the superficial tissues around it (conjunctiva).

What type of anesthesia is used for vitrectomy?

Pars plana vitrectomy is usually performed under general anesthesia including endotracheal intubation and muscle relaxation. However, for short procedures anesthesia using a laryngeal mask without muscle relaxation is also common in practice.

What is the gas bubble in retina surgery?

Gas Bubbles. When your surgeon performs a vitrectomy, the eye is sometimes filled with gas — most commonly for retinal detachments or macular holes. The purpose of the gas is to cover a defect in the retina so it can heal. In the case of a macular hole, the gas enables the hole to close.

Do they put you to sleep for retinal surgery?

Retinal surgery is usually painless and performed while you remain awake and comfortable. Advances in technology have decreased the length of surgery making outpatient eye surgery possible. Before the procedure begins, you will be given anesthetic eye drops that numb the eyes.

Is retinal surgery painful?

Retina surgery is major eye surgery. Expect the eye to hurt after surgery after the local anesthesia wears off. Much of this can be relieved with pain medicine. We strongly encourage the use of pain medicine every 4-6 hours after surgery unless there is a contraindication.

Are you put to sleep for a vitrectomy?

You may be awake during the surgery. You will receive a medicine to help you relax. In this case, your eye doctor may use anesthetic eye drops and injections to make sure you don’t feel anything. In other cases, you may have anesthesia to put you to sleep.

How do you sleep after eye surgery?

In general, you will want to do as little as possible to avoid irritating your eye. This includes rubbing and contacting your eye – even with your pillow. By sleeping on your back or the opposite side, you may be able to decrease your risk of infection after surgery.

Where is the sclerotomy placed in the retina?

Sclerotomies are placed with an MVR blade (19- or 20-gauge) at the 10 and 2 o’clock positions, 3.5 mm posterior to the limbus (3 mm if the patient is aphakic or pseudophakic). From:Retina and Vitreous Surgery, 2009

What should the intraocular pressure be during a sclerotomy?

During closure of the superior sclerotomies, the infusion maintains a stable intraocular pressure; if self-sealing incisions were used, the intraocular pressure should be slightly lowered before removal of the cannulas. In 20-gauge vitrectomy, sclerotomies are sutured carefully with partial-thickness 7.0 or 8.0 Vicryl sutures.

What kind of sutures are used for a sclerotomy?

In 20-gauge vitrectomy, sclerotomies are sutured carefully with partial-thickness 7.0 or 8.0 Vicryl sutures. In 25- or 23-gauge transconjunctival small incision vitrectomy, wounds can remain unsutured. Here, the trocar cannulas will be removed and the eye may be pressurized with a gas bubble.

How big is a 25 gauge sclerotomy wound?

Sutureless 25-gauge vitrectomy utilizes a non-tunneled roughly 0.5-mm sclerotomy, and tunneled 23-gauge vitrectomy employs a 0.72-mm sclerotomy.17If the scleral thickness 3.5 mm posterior to the limbus is 0.6 mm, then a 25° tunneled wound would be roughly 1.4 mm long (thickness/sine [angle]).
