Some issues Dr. Douglas Ryan Matsunaga, MD can help you with:

Scleral Buckle

Due to age or a genetic predisposition, the retina, or sensitive area at the back of the eyeball, can sometimes develop holes or tears. When this happens, fluid from inside the eye can get behind the retina, pushing it away from the wall of the eye. This can affect vision and potentially cause blindness. A scleral buckle is a surgical procedure performed to treat retinal detachment.

During a scleral buckle procedure, the retina is first fused back into place, often using a kind of very cold needle. Then a tiny, flat piece or band of silicone is stitched to the white area on the outside of the eyeball. This creates a small indentation (or buckle) which pushes the wall of the eye securely against the retina. It helps the retina adhere to its proper location and heal correctly.

Scleral buckle surgery may be performed along with other procedures to treat a retinal detachment, for instance removing a small amount of the liquid inside the eye. After surgery, patients may experience redness or swelling. Patients may be given eye drops or a patch to wear to protect their eye while it heals. At first, there is often an uncomfortable gritty feeling like something is in the eye. Although the buckle is permanent, this sensation soon disappears. In most cases the retina reattaches, and within a few weeks vision and eye will be back to normal.

Vitrectomy (Vitreous Surgery)

Vitrectomy is a surgical procedure to remove the clear gel (the vitreous) that fills the eyeball. This procedure is usually done in order for the surgeon to reach through the eye to the retina, which is located on the inside back of the eyeball. A vitrectomy may also be performed to remove vitreous that is contaminated with blood, infection, or debris.

Like all eye surgeries, a vitrectomy is performed using very tiny instruments that can handle delicate and exact procedures within the eye, and the surgeon often uses a microscope to see them. The idea of removing the inside of the eyeball can be unnerving, but the vitreous is replaced with a saline or silicone solution and vision is not usually affected. A vitrectomy may be performed as part of treatment for:

Retinopathy
Retinal detachment
A macular hole
Cataracts
Infection or severe injury within the eye

During surgery, patients will be given adequate anesthesia so they won't be aware of what is happening. After surgery, patients may feel some discomfort as their eyes heal Patients may have to temporarily wear an eye patch to protect their eyes, or use eye drops to help them heal. Depending on what kind of surgery patients have had, their vision may be blurry for a few days. Patients should feel better within a few days, but it may take more than a month for their vision to completely recover.
