What is a cataract?

A cataract is the clouding of your eyes natural lens, which leads to a decrease of vision.

What causes a cataract?

Most cataracts occur as part of the aging process, from a change in the chemical composition of the lens. They usually do not become a
problem until you are in your 60s or 70s.

How can I tell if I have a cataract?

You may have noticed a gradual blurring or dimming of vision. Some people see a “halo” or haze around lights, especially at night, or
have hazy or double (or multiple) vision. At first, the symptoms may only occur in dim light or when you face bright oncoming car
headlights; the glare may make night driving especially difficult.

Is it possible to have a cataract and not notice it?

Yes. If the cataract is small, it may not disturb your vision or cause any symptoms at all. Even a dense cataract may not be noticed if the
other eye is providing clear vision. In fact, you might not be aware of the blurred vision unless you happened to cover the normal eye.
Unless it is very dense, a cataract is not visible to the naked eye of an observer.

What is the treatment for cataracts?

The only effective treatment is surgical removal of the cloudy lens. This is performed in the comfort and safety of our state-of-the-art
outpatient surgery center using the latest treatment techniques and technology. Our talented eye surgeons will remove the natural lens
that has become clouded, and replace it with an artificial lens, known as an IOL, or intraocular lens.



What is glaucoma?

Glaucoma is an eye disease in which fluid pressure within the eye rises, causing optic nerve damage – if left untreated the patient may lose
vision, and even become blind.

What are the risk factors for developing glaucoma?

Increasing with age, the risk of glaucoma can affect anyone. There are a few groups who are at a higher risk of contracting glaucoma:

•Family history of glaucoma
•History of hypertension
•History of diabetes

Can glaucoma be prevented?

No, but early detection and treatment can control glaucoma and reduce the chances of damage to the eye and a loss of sight.

How is glaucoma treated?

Glaucoma is usually effectively treated with prescription eye drops and medicines that must be taken regularly. In some cases, laser
therapy or surgery may be required. The goal of the treatment is to prevent loss of vision by lowering the fluid pressure in the eye.

Will my vision be restored after treatment?

Unfortunately, any vision loss as a result of glaucoma is usually permanent and cannot be restored. This is why regular preventive eye
examinations are so important.



What is a corneal transplant? Is it safe?

A corneal transplant involves replacing a diseased or scarred cornea with a new one. When the cornea becomes cloudy, light cannot penetrate the eye to reach the light-sensitive retina. Poor vision or blindness may result.

In corneal transplant surgery, the surgeon removes the central portion of the cloudy cornea and replaces it with a clear cornea, usually donated through an eye bank. A trephine, an instrument like a cookie cutter, is used to remove the cloudy cornea. The surgeon places the new cornea in the opening and sews it with a very fine thread. The thread stays in for months or even years until the eye heals properly (removing the thread is quite simple and can easily be done in an ophthalmologist’s office). Following surgery, eye drops to help promote healing will be needed for several months.

Corneal transplants are very common in the United States; about 40,000 are performed each year. The chances of success of this operation have risen dramatically because of technological advances, such as less irritating sutures, or threads, which are often finer than a human hair; and the surgical microscope. Corneal transplantation has restored sight to many, who a generation ago would have been blinded permanently by corneal injury, infection, or inherited corneal disease or degeneration.

What problems can develop from a corneal transplant?

Even with a fairly high success rate, some problems can develop, such as rejection of the new cornea. Warning signs for rejection are decreased vision, increased redness of the eye, increased pain, and increased sensitivity to light. If any of these last for more than six hours, you should immediately call your ophthalmologist. Rejection can be successfully treated if medication is administered at the first sign of symptoms.

A study supported by the National Eye Institute (NEI) suggests that matching the blood type, but not tissue type, of the recipient with that of the cornea donor may improve the success rate of corneal transplants in people at high risk for graft failure. Approximately 20 percent of corneal transplant patients–between 6000-8000 a year–reject their donor corneas. The NEI-supported study, called the Collaborative Corneal Transplantation Study, found that high-risk patients may reduce the likelihood of corneal rejection if their blood types match those of the cornea donors. The study also concluded that intensive steroid treatment after transplant surgery improves the chances for a successful transplant.

Are there alternatives to a corneal transplant?

Phototherapeutic keratectomy (PTK) is one of the latest advances in eye care for the treatment of corneal dystrophies, corneal scars, and certain corneal infections. Only a short time ago, people with these disorders would most likely have needed a corneal transplant. By combining the precision of the excimer laser with the control of a computer, doctors can vaporize microscopically thin layers of diseased corneal tissue and etch away the surface irregularities associated with many corneal dystrophies and scars. Surrounding areas suffer relatively little trauma. New tissue can then grow over the now-smooth surface. Recovery from the procedure takes a matter of days, rather than months as with a transplant. The return of vision can occur rapidly, especially if the cause of the problem is confined to the top layer of the cornea. Studies have shown close to an 85 percent success rate in corneal repair using PTK for well-selected patients.



What is LASIK?

LASIK is a laser eye surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.

How do I know if I’m a candidate for LASIK?

LASIK can treat a broad range of nearsightedness, farsightedness and astigmatism.

You must be a minimum of 18 years of age, have a stable prescription for at least one year, and have good general and eye health. We recommend you come in for a free consultation with our LASIK Coordinator who will confirm if you are a good candidate.

Are all patients who wear glasses and contacts candidates for LASIK?

Most patients who wear glasses are good candidates for LASIK. Patients with virtually every degree of nearsightedness,farsightedness, and astigmatism are enjoying good outcomes with LASIK.

Is LASIK safe?

LASIK is an extremely safe procedure IF you are a good candidate. Our team of doctors have years of experience and have excellent results. A very small number of individuals may need a re-treatment to achieve their best outcome.

Does insurance cover LASIK surgery?

Most insurance companies consider LASIK surgery an elective surgery and it is not usually a covered benefit. However, it is certainly
worth checking with your insurance company and we encourage you to call them.
