Frequently Asked Questions

LASIK surgery, or laser-assisted in situ keratomileusis, is a procedure used to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (impaired vision due to a misshapen cornea). After making a small flap in the corneal surface layer, eye surgeons use an excimer laser to reshape the cornea’s underlying layers. This improves the cornea’s ability to focus light on the back of the eye, which results in better vision. LASIK is common in the United States, with over 700,000 patients undergoing the procedure every year.

The ideal candidate for LASIK surgery:

• is over 21 with a stable corrective prescription;
• has sufficient corneal thickness;
• is not suffering from untreated dry eyes;
• does not have too high a refractive error (i.e., prescription);
• is free of conditions that affect healing or recovery;
• has no scarring of the cornea;
• is not pregnant or nursing.

 

There may be other factors that affect your eligibility for LASIK. An Evergreen Eye Center doctor can help you determine whether or not you are a candidate for this procedure.

LASIK is an outpatient surgery, which means that patients can go home following the procedure. Though you should have someone drive you home afterward, most people are able to resume normal activities and return to work within 24 to 48 hours. Most patients see significant results from their surgery within a few hours, with vision stabilizing over a few days or weeks.

LASIK surgery is performed while the patient is awake and requires only a topical anesthetic, administered in the form of eye drops. During the procedure, patients may experience a sensation of pressure on their eye because of the suction device used to hold the eye still; however, discomfort is usually limited to a dry, scratchy feeling that can be treated with eye drops and usually resolves a few hours after surgery.

IntraLase technology uses a blade-free laser instead of a hand-held blade (microkeratome) for the initial step in LASIK. The computer-guided laser creates the flap using nothing but painless laser energy, gently sculpting the underlayers of the cornea and allowing one of our experienced LASIK eye surgeons to lift it from the eye without ever having to use a blade. In recent studies by IntraLase, this technology may now make it possible to treat those who were previously dismissed as non-candidates due to thin corneas. Studies have shown that the incidence of dry eye symptoms may be reduced with IntraLase. Bladeless LASIK has been used in more than one million LASIK procedures worldwide.

Symptoms of cataracts include:

• Clouded or blurred vision;
• The appearance of glare or halos;
• Needing increased light to read;
• Reduced night vision;
• Double or multiple images.

 

Though cataracts usually manifest the symptoms above, some do not cause any symptoms until they are in their advanced stages. Because of this, the doctors at Evergreen Eye Center recommend regular vision checkups.

Cataracts in their early stages can be treated with corrective eyeglasses. More advanced cataracts can be treated with cataract surgery, in which the cataract is removed and replaced with an artificial lens. Cataract surgery is one of the safest and most commonly performed surgeries in the United States and most patients see a significant improvement in their vision as a result of the procedure.

 

Intraocular lenses (IOLs) are surgically implanted artificial lenses that replace your natural lens and can be used to correct a range of vision problems including cataracts, astigmatism, and presbyopia.

Recent advancements have allowed the development of premium IOLs, which can allow patients to see at multiple focal points, reducing or eliminating the need for bifocals. Evergreen Eye Center offers many different types of premium IOLs; contact us today to find out which is the appropriate alternative for you.

Macular degeneration is the degeneration of light-sensitive tissue in the back of the eye (the macula) needed for clear central vision. Macular degeneration is one of the leading causes of blindness in the United States and is usually age-related, though some cases can be linked to hereditary factors.

• Dry macular degeneration is the more common of the two types and results when fatty deposits appear on the macula.
• Wet macular degeneration is caused by leakage into the retina from newly forming blood vessels in the surrounding tissue, resulting in damage to the macula.

Your eye physician may recommend special vitamins to decrease your chance of losing vision from dry macular degeneration. There are also new treatments for wet macular degeneration that have reduced long-term vision loss for many patients. Your Evergreen Eye Center expert can discuss different options with you and help you select the best course of treatment for you.

In corneal transplant surgery, a damaged or diseased cornea is replaced with a healthy donor cornea, usually acquired from an eye bank. It is an outpatient surgery, which means that patients can go home following the procedure.

Corneal transplant surgery is very common in the United States and has a high rate of success. Recent advances have further improved both the success rate and the safety of this procedure.

Glaucoma is damage to the optic nerve from a variety of risk factors such as too-high pressure in the eye. It results in loss of peripheral vision and, in some cases, blindness. It is the second leading cause of blindness worldwide, so common that we screen for it at each visit.

Although glaucoma starts with loss of vision in the periphery, working its way inward with time, the initial symptoms are so slow that it often goes undetected until it is too late to treat.

Anyone can be at risk for glaucoma, but particularly high-risk groups include:

• People over 60 years of age;
• African-Americans over 40 years of age;
• Hispanics
• People with a family history of glaucoma;
• People with diabetes;
• People with a history of trauma to the eye;
• Anyone who has used oral or inhaled steroids for other medical conditions.

Early detection is an important factor in the treatment of glaucoma, which means that regular vision checkups are key to reducing the risk of the disease.

Once identified, glaucoma can be treated using eye drops or a surgical procedure called selective laser trabeculoplasty (SLT). An Evergreen Eye Center professional can discuss our numerous advanced options for the detection and treatment of glaucoma to determine which course of action is best for you.

Diabetic retinopathy describes the effect that diabetes – a condition caused by the pancreas’ inability to regulate blood sugar – can have on your eyes.

There are two main types of diabetic retinopathy:

• Non-proliferative: In non-proliferative diabetic retinopathy, weakened blood vessels can leak or bleed causing floaters, blurred or double vision and even vision loss.
• Proliferative: In proliferative diabetic retinopathy, a network of blood vessels actually grows over the retina, impairing the patient’s vision.

Treatment options for diabetic retinopathy include laser surgery, injection of medication into the eye, and, in some cases, surgical repair of the retina.

Diabetic retinopathy is a serious medical condition that requires comprehensive, specialized treatment by a trained eye care professional. An Evergreen Eye Center expert can discuss different options with you for keeping your eyes healthy and safe.

The Visian Implantable Collamer Lens (ICL) surgery is an FDA-approved alternative to LASIK for treating moderate to severe nearsightedness. It is an option for people who cannot have LASIK and an alternative for many who are eligible for LASIK but demand superior vision or are uncomfortable with laser surgery. The procedure does not contribute to dry eye and is reversible. The Implantable Collamer Lens (ICL) is placed in the eye to improve focusing without disturbing or replacing a patient’s natural crystalline lens.

Dry eyes are a medical condition with health and lifestyle consequences if left untreated. There are two primary forms of dry eye – evaporative (which is associated with a deficiency in the oily layer of your tears) and aqueous deficient (which is associated with a deficiency in the watery layer of tears). As part of our dry eye evaluation, the doctor will use several tests to assess and identify the root cause of your dry eye symptoms and recommend the best treatment for you.

Meibomian glands are the oil-producing glands of your eyelids. If these glands do not produce enough oil or become blocked, it may contribute to your symptoms of dry eye.
