Laser vision correction has changed the landscape of ophthalmology over the past few decades. What started with basic cornea reshaping has evolved into highly sophisticated procedures such as Contoura LASIK. This evolution reflects a commitment to safer outcomes, greater precision, and more personalized care. Here are some of the key milestones in laser vision correction, offering clarity for ophthalmologists interested in the field’s latest advancements:
Early Treatments with Photorefractive Keratectomy
The introduction of photorefractive keratectomy (PRK) marked a turning point in vision correction. PRK was the first procedure to use an excimer laser to reshape the corneal surface. By gently removing the outer layer of the cornea, this method helped improve refractive errors. Healing sometimes required a few days, as the epithelium needed time to regenerate. Though PRK required patience from both the patient and the doctor, it set the standard for what laser vision correction could achieve.
Advancing Recovery with Epi-LASEK
Epi-LASEK arrived next, offering an alternative to PRK’s approach. This technique combines the benefits of both LASIK and PRK. A thin sheet of epithelial cells is separated using a specialized tool, then preserved and repositioned after the laser portion is completed. This adjustment helped to minimize discomfort during recovery while providing reliable results. For patients with thin corneas or specific concerns about flap-related complications, Epi-LASEK offers an alternative practical option.
The LASIK Era
LASIK is a popular option thanks to its faster recovery time and minimal discomfort. The approach involves creating a thin flap in the cornea, reshaping the tissue underneath with a laser, and then repositioning the flap. With fewer side effects and rapid visual improvement, LASIK became one of the most common vision correction procedures.
Over time, innovation led to the introduction of topography-guided LASIK, also known as Contoura LASIK. This technique maps the unique surface of each patient’s cornea, allowing greater precision and customization in each treatment. Ophthalmologists have adopted topography-guided approaches to address individual corneal irregularities and deliver more predictable visual outcomes.
Fortified LASIK and Structural Support
Building on traditional LASIK, fortified LASIK provides additional support during the healing process. This newer technique includes supplemental collagen cross-linking, enhancing corneal biomechanics during recovery. Such fortification offers reassurance, especially for patients with specific structural concerns. Ophthalmologists who oversee challenging cases find this method practical for minimizing risks while optimizing visual outcomes.
SMILE Procedure
More recently, the small incision lenticule extraction (SMILE) procedure introduced a minimally invasive option. Using a femtosecond laser, SMILE creates a small tissue disc (lenticule) inside the cornea, which is then removed through a tiny incision. Since SMILE avoids the need to create a large corneal flap, it reduces disruption to the cornea’s surface and may offer an alternative for certain patient profiles.
Explore Contoura LASIK and Other Procedures
Laser vision correction techniques continue to advance, driven by an ongoing desire to match patient needs with precise solutions. Each new technique offers fresh ways to improve comfort and visual results while supporting a personalized approach. For ophthalmologists, staying current with these developments offers opportunities for professional growth and strengthens the patient-doctor relationship.
