Eye doctors focus on new system to spur laser surgery

After surging in 1990s, demand for corrected vision has cooled a bit

More than 5 million Americans have had their eyesight fixed using laser surgery, but millions more still think their glasses and contact lenses will do just fine.

Demand for the laser procedures, which soared in the 1990s, has been sliding ever since the peak year in 2000. Vanity has been trampled by consumers' thriftiness in the face of the lousy economy, along with lingering fears about the surgery's safety.

That has caused big problems for the medical chains doing the procedures, and the laser manufacturers building the equipment. Their profits and stock prices have tumbled. Some have been forced to merge.

But now they have their eyes on a new prize - one they hope will convince more consumers to take another look at laser surgery.

Called wavefront-guided surgery, the new system is just being rolled out. It's expected to allow doctors to treat eye disorders that previously couldn't be detected, make eyesight even better and reduce many of the side effects of laser operations such as poor night vision. It also will cost more than conventional laser surgery.

"It's the biggest breakthrough in laser vision correction since the invention of the laser technique," said Dr. Thomas Tooma, California medical director for TLC Vision Corp., whose TLC Laser Eye Centers is the largest chain performing the procedures.

Wary consumers

Consumers' anticipation about the new system is another reason they're delaying laser surgery, leaving the companies to muddle through until the wavefront system is more widespread.

Visx Inc. of Santa Clara, Calif., the dominant maker of laser-vision machines, reported last week another decline in profit, saying its fourth-quarter earnings fell 7 percent, to $3.9 million from $4.2 million a year earlier.

Visx makes money two ways: selling its machines and charging doctors a $100 fee for each procedure using Visx's equipment. The fees represent the majority of Visx's revenue and are the key to its long-term success. But in the fourth quarter, those licensing royalties and service fees were flat compared with a year earlier.

"They fairly well represent what's happening in the whole industry," said David Harmon, president of Market Scope of Manchester, Mo., which tracks the laser-vision business.

Visx is starting to sell its new wavefront system to international customers and to American surgeons with the expectation that the Food and Drug Administration will approve the new procedure this spring.

As a result, Visx's fourth-quarter sales of equipment increased to $15.7 million from $7.8 million a year earlier.

TLC Vision began using the new method this month with equipment from the Swiss company Alcon Inc., which already has FDA approval.

Even though Visx is the largest maker of laser-vision machines with nearly 60 percent of the U.S. market, Alcon and several other rivals have entered the business in recent years and contributed to the slowdown in Visx's growth.

Peaked in 2000

The number of U.S. procedures peaked at 1.42 million in 2000, then dropped to 1.31 million the next year and 1.15 million in 2002, according to Market Scope.

The most popular form of the surgery is dubbed lasik, short for laser-assisted in-situ keratomileusis, which takes only a few minutes. It's used to correct nearsightedness, farsightedness and other maladies.

Harmon estimates the number of operations will bounce back to 1.3 million this year, but he acknowledged that his prediction carries optimistic assumptions, such as the economy picking up steam in the latter half of the year.

Industry executives and doctors blame the laser-vision slowdown in large part on the poor economy. The surgery generally is an elective procedure that's often not covered by insurance and typically costs $1,500 to $2,000 for each eye.

When the economy falters and households cut spending, "this is a very easy decision to delay," said Theodore J. Huber, an analyst at Banc of America Securities. "You just keep wearing your contacts and glasses."

Consumer fear is another factor. Although studies show that more than 98 percent of patients are satisfied, negative publicity about the minority who complain of side effects or damaged eyes leaves many prospective patients skittish, said Tooma of TLC Vision. "If I was to rate" the industry's troubles, he said, "fear is No. 1."

But he added that the fear factor likely "will be addressed" by the new wavefront technology, which is often referred to as "custom lasik" because it effectively takes a "fingerprint" of each patient's eyes.

After Visx gets FDA approval and launches its new wavefront method, it plans a "substantial" increase of its $100-per-procedure fee, according to Visx CEO Elizabeth H. Davila.

"As these custom procedures are blended into our mix," she said, Visx's income should grow even if the number of users remains flat.
