Some issues Dr. Alexander C. Walsh, MD can help you with:

Dacryocystorhinostomy (DCR)

Dacryocystorhinostomy, or DCR, is a surgical procedure used to bypass a blocked tear duct.

Normally, the tears that constantly bathe the eyes are drained through two tiny holes in the eyelid, where they run through a duct into the nose. This tear duct can become clogged or blocked, causing tears to back up and leading to watery eyes. Common causes of tear duct blockages include trauma, a facial tumor, and inflammation due to certain medical conditions, but usually the cause is not known. Clogged tear ducts are especially common in young children. If the blockage is permanent and located lower in the duct, near the nose, DCR may be performed to create a bypass and allow tears to drain freely again.

During DCR surgery, a small hole is made in the bone and tissue between the upper part of the tear duct and the nasal passage. Usually, a tiny plastic tube called a stent is placed into the opening to protect it and keep it open during healing. DCR may be performed through an open incision on the upper cheek near the nose, or it may be performed endoscopically using tiny instruments that are passed through the nostril. Open surgery is more common, and has a slightly higher success rate, although endoscopic surgery causes less pain and bleeding during recovery. DCR is able to correct the blockage and watering eyes in nearly 95% of cases.

The surgery itself takes only about half an hour. It is usually done under general anesthesia, which may require a short hospital stay while patients recover. Small amounts of bleeding from the nose are not uncommon for the first 24 hours, and bruising and swelling are expected for the first two weeks. Don't be alarmed if the eye continues to water at first. Swelling in the area due to surgery can cause the eye to water, but this should go away as patients heal.

LASIK

LASIK (laser-assisted in situ keratomileusis) is a surgical procedure that improves vision by permanently correcting refractive vision errors. Refractive vision errors are sight problems (such as nearsightedness, farsightedness, and astigmatism) that typically require patients to wear contact lenses or glasses. Nearsightedness (myopia) causes blurred vision at a distance, while farsightedness (hyperopia) makes objects that are up close appear blurry. Astigmatism results in blurred vision at both near and far distances. Each eye is either nearsighted or farsighted, and can additionally have astigmatism. These refractive vision errors develop from imperfections in the curvature of the eye, which LASIK fixes through the use of a laser. The laser changes the shape of the eye by cutting away tissue from the cornea (clear outer layer of the eye).

LASIK is generally considered an elective procedure (not medically necessary) since patients can wear glasses or contact lenses instead of undergoing LASIK. Nevertheless, many people still elect to undergo LASIK to have better vision without having to wear corrective lenses. Certain professionals, such as pilots, military members, firefighters, and athletes, might particularly benefit from LASIK.

Ophthalmologists (eye doctors) evaluate patients before surgery, measuring the cornea and checking for any eye irregularities that would disqualify patients from LASIK. A special eye scanner is used to create a map of the cornea. This map guides the surgeon in developing an individualized LASIK treatment plan. Once approved for LASIK, contact-wearers are advised to switch to glasses for the three weeks leading up to their surgery.

LASIK is a brief procedure, lasting for about half an hour, depending on the state of a patient's eyes and the corneal reshaping required. Patients lie down on a reclining chair and have numbing eye drops applied to one or both eyes to eliminate pain and discomfort during the procedure. While the eyes are held open by a device, the eye surgeon raises a fixation light where patients direct their eyes. The surgeon uses a femtosecond laser to cut a precise circular incision in the cornea's surface. The surgeon then manually folds back the corneal flap to access the stroma (inner cornea).

An excimer laser is then used to remove certain amounts of corneal tissue. For patients with farsightedness, the laser cuts tissue on the outer regions of the cornea, making the central cornea more prominent. For patients with nearsightedness, the opposite is done; central corneal tissue is removed while the outer tissue is left alone, flattening the eye. In patients with astigmatism, the laser is used to even out the surface of the corneal tissue, making the eye more spherical. When the lasering process is complete, the ophthalmologist folds the corneal flap to its regular position. The flap quickly begins to heal and naturally reattach itself to the eye.

LASIK patients need someone to drive them home from the procedure and cannot drive for the following 24 hours. Recovery from LASIK lasts about five days. Patients typically notice improved vision within a day or two of surgery. Prescription eye drops are given to patients to alleviate discomfort and promote eye healing. During this recovery time, patients must be incredibly careful not to touch or rub their eyes. Ophthalmologists often instruct patients to wear protective glasses during the day and night to prevent potential damage from eye rubbing.

LASIK can improve the experience of certain activities such as swimming or reading, and in some cases, LASIK can be a life-changing procedure for those with severe refractive vision errors. LASIK may also save patients money by eliminating the recurring need for updated corrective lenses.

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.
