Eye Surgeries

Eye Surgery performed at PCVI in Eugene At ClearVision we specialize in the surgical treatment of eyes. We routinely perform a broad range of procedures right here in our state of the art operating rooms.

Whether you need a simple cornea replacement, or the most complex retinal repair, we can do it. Our surgeons are highly trained and experienced in almost any form of surgical eye repair. Contact ClearVision if you have any questions regarding your specific circumstances. Listed below, are several common procedures performed by the specialists at PCVI.

Corneal Transplant

The cornea is the outermost clear covering of the eye that is responsible for 60% of our eye's focusing power. When this tissue becomes distorted or clouded, vision can be severely impaired. Some of the conditions which cause corneal problems are keratoconus (a warping of the cornea), Fuchs's dystrophy (a condition where loss of the inner permanent cell layer causes swelling), and infection leading to scarring of the cornea. Since corneal problems are so visually debilitating and common, corneal transplant surgery can restore sight to affected individuals. Corneal transplant involves the replacement of the diseased corneal tissue with a normal donor cornea from a recently deceased individual. The tissue is extensively tested for clarity, proper cell concentration and made sure to be free of any disease.

Using a special trephine, or surgical instrument to remove the diseased cornea, a "button" of tissue is lifted from the eye. The donor cornea is then surgically trimmed to fit exactly into this space. Using sutures, the donor corneal tissue is microscopically sutured in place. Typically vision remains quite blurry for several weeks or months following surgery. Depending on the amount of astigmatism, nearsightedness or farsightedness, a person's vision may improve even faster. Patients are followed closely and the sutures are adjusted as needed to reduce astigmatism and improve vision. Eventually, most sutures will be removed but many times sutures will remain indefinitely. Patients who undergo corneal transplant surgery typically experience some discomfort but there is usually no pain.

Glaucoma Repair

Typically doctors start with eye drops to lower the eye pressure into a normal range. If eye drops do not work well to lower the pressure, the next consideration is the use of a laser or surgery. Argon lasers are designed to treat the drainage ports inside the eye to allow for faster drainage of fluid. This, in turn, will lower the eye pressure. Most individuals undergoing laser treatment in the eye experience a significant reduction of eye pressure for several years. The effect can wear off but the treatment can be repeated. Certain types of glaucoma respond best to this treatment so your doctor will decide which form of treatment is best for you.

If laser is ineffective or is not the right treatment, a glaucoma surgery called a "trabeculectomy" is the next step in lowering the eye pressure. Often done at the time of cataract surgery, a small window is created inside the eye to allow the fluid to drain under the outer coatings of the eye, thus reducing the pressure. This is successful in over 90% of cases and is typically permanent. However, some individuals may need to continue eye drops to maintain an acceptable pressure. Glaucoma is a disease of the eye that can be managed successfully if it is detected early.

Macular Degeneration Therapy

There are a number of different treatments for macular degeneration. There are several different retinal lasers, which may or may not be used in conjunction with special medication, as well as standard argon laser treatment. The type of laser used to stabilize macular degeneration will depend on the results of a fluorescein Angiogram.

Macular Hole Surgery

The goal of macular hole surgery is to relieve the tension on the surface of the retina. In order to achieve this goal, a vitrectomy is performed to remove the vitreous gel. This procedure is followed by the removal of a delicate tissue on the surface of the retina, which is causing the hole to remain open. Finally, a special medical-grade gas is then inserted into the eye to flatten the retina for at least one week.

Oculoplastic Surgery

The most common surgery done cosmetically is the eyelid lift surgery, or "blepharoplasty". Given time, the upper and lower lids tend to sag and in some cases, even block vision. Should vision blockage be significant, the lid surgery can be considered medically necessary and many times insurance will cover the surgical costs of treating the upper lids. Most commonly the lower lid surgery is considered elective. Other surgery involving the eyelids may be needed in cases of eyelid cancers, trauma to the eyelids, and for removal of moles or lesions on the lids. Treatment of entropion or ectropion, conditions where the lids are not properly situated against the eyeball, is a commonly performed lid surgery.

Brow lifts are done for those where the brow droops over the visual line of sight. Raising the brow involves placing incisions over the eyebrows and lifting the upper brow out of the line of sight surgically. Lasers are currently used extensively in skin surgery around the eyes. Removal of lines, moles and blemishes as well as unwanted hair is made easy using lasers. Tear duct surgery is also performed with the use of lasers.

Retinal Detachment Surgery

Retinal detachment is a condition where the retina comes away from the back wall of the eye and can cause sudden loss of vision. Symptoms include flashes of light and floaters as well as loss of vision such as a curtain being pulled over part of the vision. Should this occur, the surgeon will reattach the retina using a special sponge "buckle" around the eye. Prior to placement of the buckle, the vitreous is removed and the fluid under the detached retina is removed to allow it to lay flat against the back of the eye. This is quite an involved procedure but in many people can restore vision.

Retinal Lasers

A laser is a commonly used medical surgical instrument, which uses light energy to either burn away diseased tissue, seal the retina, or promote healing of the tissues of the back part of the eye (the retina). Laser surgery is used for a number of different retinal diseases, ranging from fluid accumulation (macular edema) to bleeding from diabetes. The treatment is performed typically in the office setting.

Vitrectomy

Vitrectomy surgery describes a variety of different techniques to treat conditions of the retina and the vitreous. These techniques involve the removal of the vitreous gel, which normally fills the eye. After the surgery is completed, the gel is gradually replaced by fluid that the body produces naturally. Vitrectomy surgery is generally more complicated than other types of eye surgeries such as a cataract operation.
