As technology continues to advance, so do the options available for correcting vision problems. One of the most exciting developments in recent years has been the introduction of the excimer laser, which is used in a procedure known as LASIK (laser-assisted in situ keratomileusis) to reshape the cornea and improve vision. Another option that has gained popularity in recent years is called photorefractive keratectomy (PRK), also known as “surface ablation.”

But there is another option that is gaining attention in the world of refractive surgery: the excimer laser platform known as “wavefront-guided” or “custom” LASIK. This procedure, also known as “advanced surface ablation” or “trans-PRK,” uses a special device called a wavefront analyzer to create a detailed map of the patient’s eye, which is then used to guide the laser during the procedure.

This technology is often referred to as “custom” because it allows the surgeon to tailor the procedure to the unique characteristics of each patient’s eye. This is different from traditional LASIK, which uses a “one-size-fits-all” approach.

The excimer laser used in wavefront-guided LASIK is the same as the one used in traditional LASIK and PRK. However, the difference lies in the way the laser is guided during the procedure. With wavefront-guided LASIK, the surgeon uses a wavefront analyzer to measure the unique imperfections in the patient’s eye, including higher-order aberrations that cannot be detected with traditional diagnostic tools.

The wavefront analyzer creates a detailed map of the patient’s eye, which is then used to guide the laser during the procedure. This allows the surgeon to correct not only the patient’s refractive error (nearsightedness, farsightedness, or astigmatism), but also any higher-order aberrations that may be contributing to the patient’s vision problems.

The result is a more precise and customized procedure that can improve the patient’s vision beyond what is possible with traditional LASIK or PRK. In fact, studies have shown that wavefront-guided LASIK can improve visual acuity, contrast sensitivity, and reduce the risk of glare and halos at night.

However, it is important to note that not all patients are good candidates for wavefront-guided LASIK. Patients with severe refractive errors or corneal irregularities may not be eligible for this procedure. Additionally, wavefront-guided LASIK may not be covered by insurance, as it is considered a “premium” procedure.

Overall, wavefront-guided LASIK is an exciting development in the world of refractive surgery. It offers a more precise and customized approach to correcting vision problems, and has the potential to provide patients with better visual outcomes than traditional LASIK or PRK.
