Contact Lenses vs Laser Surgery

Every choice carries benefits and risks. Weighing them can be tricky. But the pros and cons of buying contact lenses versus having laser surgery can be boiled down to a few simple guidelines.

Any decision made between getting contacts or laser surgery on your eyes should be made in consultation with your eye care professional, of course. But getting them to stand still long enough to answer your questions can be a challenge. Here are some guidelines that will help you go in prepared.

Cost is the first consideration for most people, and it's a valid one. While everyone rightly considers his or her health paramount, most people won't look into the health risks until they know whether they can afford the options.

Contact lenses are not cheap. But, they're relatively low cost compared to laser surgery and are more often covered by insurance programs. A pair of contact lenses may run anywhere from $20 to $100, but there are other costs associated with this option, including cleaning solution and doctor visits. Still, the total may be less than $200 per year, not including the value of your time spent in the doctor's office.

Laser surgery, by comparison, can cost anywhere from $2,000 per eye to $5,000 per eye. Include doctor visits and the total is about $4,500 to $11,000. On the upside, it is a one-time cost and some insurance programs will help in part to offset it.

The convenience factor involved is no small matter to most people, either. The thought of having one procedure that is (usually) painless, brief and reliable versus having to wear contacts for a lifetime is very attractive to many. And, rightly so. While contacts have evolved considerably over the years, they still require daily to monthly changing and replacement every two to three years. Disposables are changed from every day to once per month.

Still, the health risks - while low for either option - should not be dismissed.

Laser surgery rarely results in any long-term negative health impact. But some patients do experience dry eye (lowered ability to produce tears, leading to discomfort and reduced vision). While rare, it's possible for surgery to actually reduce vision acuity. More often, though still very uncommon, patients report halos, reduced ability to see clearly in fog or lower light, and other issues that interfere with good vision.

Contact lenses, even today though, are not entirely without risk. All contact lenses reduce the amount of air that gets to the surface of the eye. That increases the odds of corneal infection. Modern RGP (rigid gas permeable) lenses allow five times more oxygen through than contact lenses of the past. But it's still not the same as wearing no contacts at all.

Contact lenses can also lead to corneal or sclera scarring. Sclera is the relatively hard surface tissue of the outer eye that protects the eyeball. That is more likely if a piece of grit gets between the contact and eye. Unlikely, but not unknown.

Still, both options carry very little health risk overall. The overwhelming majority of people come through laser surgery with greatly improved vision. Nearly everyone who wears contact lenses of any type daily, whether extended wear or daily-wear, have no problems at all. They adjust rapidly, keep them clean and sanitary, and don't need to think about them during use.

Look to your budget and consult your eye care professional about the options, making sure to have a frank conversation about risks and likely benefits. You'll then arrive at the choice that's best for you.
