Contoura Vision is a type of LASIK that uses detailed topographic mapping of your cornea to guide the laser treatment, creating a correction pattern unique to each eye. Unlike standard LASIK, which corrects your prescription in a more uniform way, Contoura maps 22,000 individual elevation points on your cornea’s surface to identify tiny peaks and valleys that affect how light enters your eye. The result is a more personalized reshaping that can produce sharper vision and fewer visual side effects like glare at night.
How Contoura Differs From Standard LASIK
All LASIK procedures reshape the cornea with a laser to correct nearsightedness, farsightedness, or astigmatism. The difference is in how the laser decides what to remove. Standard wavefront-optimized LASIK accounts for the general curvature of your cornea and applies a correction based on your glasses prescription. Contoura goes further by incorporating the unique surface irregularities of your individual cornea into the treatment plan.
Think of it this way: your glasses prescription tells the surgeon how much correction you need overall, but your cornea isn’t a perfectly smooth sphere. It has subtle ridges and dips that scatter light in ways a standard prescription can’t address. Contoura’s topographic map captures those imperfections and programs the laser to smooth them out at the same time it corrects your vision. This means the laser removes tissue in a highly customized pattern rather than a uniform one, treating astigmatism, nearsightedness, and corneal irregularities simultaneously.
The Mapping and Planning Process
Before surgery, a diagnostic device called the Topolyzer VARIO captures images of your cornea using a system of concentric rings projected onto its surface. The way those rings reflect back reveals the precise shape of your cornea across thousands of data points. Multiple scans are taken and compared to ensure accuracy. Surgeons typically select the four best-quality maps, confirm they agree with each other within tight tolerances, and then average them into a single composite map.
On the day of surgery, that composite map is loaded into the laser system. The surgeon reviews the proposed treatment profile, cross-references it with your clinical prescription, and fine-tunes the final correction. This step is important because it allows the surgeon to reconcile what the topography shows with what your eye exam measured, adjusting the sphere and astigmatism correction as needed before the laser fires a single pulse.
Visual Outcomes Compared to Standard LASIK
Clinical studies show Contoura tends to produce sharper uncorrected vision than wavefront-optimized LASIK. In a comparative study, 88% of eyes treated with Contoura achieved 20/20 vision or better, compared to 75% of eyes treated with standard wavefront-optimized LASIK. The advantage was even more pronounced at the sharpest levels: 36% of Contoura-treated eyes reached 20/16 vision, versus 22% in the standard group.
These differences matter most for people who want the crispest possible vision without glasses. Getting to 20/20 is the baseline goal of any LASIK procedure, but Contoura’s ability to push a larger percentage of patients beyond 20/20 reflects the benefit of addressing those subtle corneal irregularities that a standard treatment leaves untouched.
Night Vision, Glare, and Halos
One of the most common complaints after any LASIK procedure is visual disturbances at night: halos around lights, starburst patterns, and increased glare that makes driving uncomfortable. These symptoms happen because the reshaped cornea can scatter light in ways the brain isn’t used to processing, especially when the pupil dilates in low light.
Because Contoura smooths out microscopic corneal irregularities, it tends to reduce the optical imperfections that cause these problems. Some mild visual disturbances are still normal in the first few weeks after surgery as the cornea heals, but most patients see significant improvement over time. The risk of permanent glare or halos is very low.
Who Is a Candidate
Contoura is FDA-approved to correct up to 9 diopters of nearsightedness on its own, or up to 8 diopters of nearsightedness combined with up to 3 diopters of astigmatism. If your prescription falls within those ranges, you may be a candidate. The same general LASIK requirements apply: you need adequate corneal thickness, stable vision, and healthy eyes without conditions like keratoconus or uncontrolled dry eye.
People with significant corneal irregularities may actually benefit the most from Contoura, since the topographic approach is specifically designed to address surface imperfections that standard treatments overlook. On the other hand, if your corneas are already very smooth and regular, the practical difference between Contoura and standard LASIK may be smaller.
Dry Eye After Surgery
Dry eye is the most common side effect of any LASIK procedure. Roughly half of all LASIK patients experience dry eye symptoms at one week, about 40% at one month, and between 20% and 40% still notice some dryness at six months. These numbers apply broadly across LASIK types.
Interestingly, one study tracking Contoura patients found that dry eye scores actually improved after surgery. Patients reported an average dry eye severity score of 27 before the procedure, which dropped to 7.5 at three months. This likely reflects the fact that many people wearing contact lenses already have significant dry eye, and removing the need for contacts can improve surface comfort over time. No adverse events were reported in that study, though individual experiences vary.
Recovery Timeline
The procedure itself takes only minutes per eye. Recovery follows the same general timeline as standard LASIK. Most people can drive within 24 hours and return to work within one to three days. You can shower after the first day, but eye makeup should wait a full week.
Physical activity follows a graduated return. Light exercise like walking or stretching is fine within the first week. Jogging and light weights can resume after about a week, with intense workouts and heavy lifting at one to two weeks. Contact sports require two to four weeks. Swimming with goggles is usually cleared at one to two weeks, but hot tubs and open water should wait at least two weeks. Flying is fine within a day or two.
Your vision will likely feel noticeably better within the first day, but complete healing and visual stabilization takes three to six months. During that time, minor fluctuations in sharpness or mild dryness are normal and expected.
Cost and Availability
Contoura Vision is typically more expensive than standard LASIK because of the additional diagnostic imaging and customized treatment planning involved. The exact price varies by surgeon and region, but you can generally expect to pay a premium of a few hundred dollars per eye over standard wavefront-optimized LASIK. Since LASIK is considered elective, insurance rarely covers any portion of the cost regardless of the technique used.
Not every LASIK center offers Contoura. The procedure requires the specific Alcon WaveLight laser platform and the Topolyzer diagnostic system, so availability depends on your surgeon’s equipment. If Contoura is important to you, confirm that the practice uses this specific system before scheduling a consultation.
