1. "I use my eye chart as a crutch."
Managed care continues to put a dent in all doctors' profits, but eye doctors have become especially vulnerable. Falling reimbursements have flattened once-hefty profits on procedures such as cataract surgery, and HMO hassles make it tempting for many patients to blow off that annual eye exam.

As a result, many optometrists (who provide primary eye care) and ophthalmologists (M.D.s who can perform surgery) are adapting shrewder business tactics to keep costs down and patient traffic brisk. For instance: Walk into any eye doctor's office and you're likely to see the trademark pyramid of letters that's at the heart of every eye exam. But some doctors use the eye chart as the main or worse, only component of an eye exam. A full checkup should include a glaucoma test, a check for near vision (in which you look at a target within reading distance) and dilation of the pupil, so that the doctor can look at the back of the eye to detect cataracts or age-related diseases.

2. "Glasses are my cash cow..."
In 2001, Glenn Ferguson visited the eye doctor for the first time in five years. The 33-year-old engineer from Buffalo, N.Y., says he was prepared to buy new glasses but not for the $200-plus price tag he was given at his doctor's office. Ferguson considered going elsewhere for the glasses but didn't want to pay for another exam.

Since optometrists and ophthalmologists rarely hand over eyeglass prescriptions without prompting, most people don't know that federal regulation requires eye doctors to release them so that patients can comparison-shop for glasses. And why would they? In order to offset the high overhead of managing a practice, doctors and optical retailers may jack up the prices of glasses they sell from 50% to 80%, estimates Harold Koller, an ophthalmologist in Meadowbrook, Pa. "Some of my friends say the annual profit of having a dispenser in their office is between $25,000 and $50,000." After learning he was entitled to his prescription, Ferguson took it to Wal-Mart, where he found a pair of glasses similar to those at his doctor's office, but for $100 less.

3. "...and contact-lens discounters are my enemy."
Contact lenses are another area where you can save a lot of money, given the chance. Mail-order distributors, discount chains and online retailers offer discounts of about 20%. And while some doctors will hand over the prescription if you ask, many don't have to: There is no federal law requiring doctors to release contact-lens prescriptions.

But there's some good news for patients. Major contact lens manufacturers including Bausch & Lomb, CIBA Vision and Johnson & Johnson along with the American Optometric Association, are agreeing to settlements in federal court on allegations of conspiring to strong-arm consumers into buying contact lenses from eye doctors. The lawsuit alleged that the manufacturers and the optometric association tried to limit contact lens sales to eye doctors or retail outlets and that the association encouraged optometrists to withhold prescriptions from their patients.

4. "Your kid may not even need glasses."
In school yards across the country, "four eyes" is no longer an insult. Glasses are hot, and eye doctors are ready to cash in on the trend. According to Koller, outgoing chairman of the American Academy of Pediatrics' section on ophthalmology, children are more likely than adults to want glasses they don't need because "the people they idolize often wear glasses." (Blame that Potter kid.) But kids' glasses can run upwards of $300.

How can you tell whether your kids really need glasses? The most common eye problem in children under five is excess farsightedness (indicated by headaches, eye fatigue and crossed eyes); after five, Koller says, nearsightedness is more likely, evidenced by sitting close to the TV or squinting to see things far away. If your child is showing symptoms, see your pediatrician first, Koller advises. Those headaches could be the result of sinus problems, a learning disability or even migraines, a common cause of blurred vision in school-age children. "Glasses don't cure everything," says Koller.

5. "I blur the truth about laser surgery."
Lasik the procedure that uses a laser to correct vision by reshaping the cornea is all the rage with patients and ophthalmologists alike, and it's easy to see why. In the 15 minutes it takes your doctor to zap a laser in both of your eyes, he earns enough to buy a ticket to Honolulu. According to John Pinto, president of an ophthalmic management-consulting firm in San Diego, the typical Lasik practice earns a 30% margin on a procedure that costs the consumer, on average, $1,200 per eye.

6. "I learned Lasik in four days."
Is four days enough time to learn how to operate on a patient's eyes? At least one Lasik course director thinks so. The following advertisement was found on EyeWorld.org, an online publication for ophthalmologists: "SUMMER SPECIAL!! Obtain Lasik skills in a four-day, complete training course and avoid the awful 'learning curve.'" Gabriel Child, director of the course in question, The Real Lasik Course, defends his program by saying that he has found no significant difference in complications between the procedures performed by newbies and those done by the teaching ophthalmologists.

But if a Cliff Notes version of surgical training doesn't sit well with you, ask your surgeon how many procedures he or she has performed. Trattler who learned Lasik at a yearlong cornea fellowship at the University of Texas Southwestern Medical Center says a high number doesn't necessarily mean a better surgeon, but the average surgeon will surmount the learning curve after about 100 cases.

7. "Surgery's wrong for you? Don't expect me to stop you."
To Erik Petersen, a 25-year-old artist from Prescott, Ariz., laser surgery seemed like the perfect solution: He had never liked glasses, and his persistent dry eyes made it hard to wear contacts. Surgery, however, did little to fix his vision. As the doctor worked on his left eye, Petersen felt a sharp pain "that freaked me out" so much that the doctor couldn't operate on the other eye. It was a blessing in disguise. With his left eye, he now sees massive halos over objects, and every morning it "feels like it's glued shut." And since his vision in each eye is now so different, contacts are his only option.

Before surgery, Petersen says, the doctor's staff told him that his pupils were abnormally large and, as a result, he might experience halos and other side effects. "But they made it seem like it wasn't a big deal." He also says he was called a "perfect candidate for the surgery." Petersen's Phoenix-based doctor denies calling him a perfect candidate, adding that "we caution and spend time with people who have larger pupils." (Petersen signed a consent form acknowledging that because of large pupil size he might be at a higher risk for complications.) Trattler says that people who want Lasik because they can't wear contacts may indeed have a dry-eye problem after the surgery. Other patients who should think twice about Lasik: anyone who's had a herpes infection, a lazy eye, or severe myopia or astigmatism.

8. "Sterile equipment? Nope. But hey, we washed it."
Peter Brett, a 42-year-old oncologist in California, was horrified back in 2001 when he read an article from the San Francisco Chronicle about the eye center where he and his wife had both had laser surgery; supposedly, instead of sterilizing the surgical microkeratome blades, the clinic rinsed and reused them. Brett was so concerned that he and his wife were tested for Hepatitis B and C, as well as HIV. (All tests were negative.) In a settlement to an investigation brought by the Medical Board of California, the doctors in question admitted that the protocol was to rinse and reuse a blade on up to four eyes; the board concluded that the doctors departed from the standard of care and placed them on probation.

9. "Open your eyes and I'll be gone."
Ever heard of "co-management"? It's a controversial trend in eye care in which an eye surgeon can share postoperative checkups with an optometrist who, in turn, gets a cut of the surgery fee. This arrangement sometimes makes sense for patients, especially those who live in rural areas and have had surgery far from home.

But it can also be disastrous, since the risk of complications bleeding, infection or retinal detachment are much greater in the first 10 days after surgery, says Alan Mendelsohn, president of Florida's Broward County Medical Association. "There's no other specialty in medicine," he says, "where a surgeon doesn't see his patients postoperatively."

10. "You're a guinea pig."
Eye care is one of the most rapidly advancing areas of science, and the benefits to patients can be life-changing. In fact, it's quite easy to find an eye doctor conducting a clinical trial of some new, experimental treatment. Devices that aren't approved by the FDA for any use, however, require informed consent from all patients. Unfortunately, when it comes to fully understanding the risks, patients are often in the dark.

How can you protect yourself? Linda Puetz, an education specialist at the Kansas City, Mo.-based Midwest Bioethics Center, advises patients to ask whether the doctor has any financial incentive (many own stock in the companies that manufacture the devices). And don't assume your doctor understands all the risks.
