What is LASIK and How Has It Evolved?

LASIK is a surgical procedure approved by the United States Food and Drug Administration to use laser technology to correct refractive errors in the eye. These include myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism. It achieves this by reshaping the cornea - the transparent front part of the eye - to ensure that light entering the eye can be properly focused onto the retina for clear vision.

The initial phase of LASIK involved the use of a microkeratome, a mechanical blade, to create a corneal flap. The surgeon would then use an excimer laser to reshape the cornea. However, the use of a mechanical blade posed some risks, including irregular flaps and flap dislocation.

This all changed with the advent of femtosecond laser technology in the early 2000s, which allowed for bladeless LASIK, also known as IntraLase. The femtosecond laser, which operates on a principle known as mode locking, or emitting ultra-fast pulses of light to create a precise, thin flap in the cornea, reducing the risks associated with the mechanical blade. Today, the bladeless approach has become the gold standard in LASIK procedures.

LASIK, from its early beginnings to its advanced state today, represents the evolution of a transformative technology aimed at improving the quality of life by enhancing vision. At ClearSight, we embrace these advancements, utilizing state-of-the-art technology to provide our patients with the highest standards of safety, precision, and personalization, delivering on our promise to help you experience the freedom of clear sight.

Customized LASIK: An Individualized Approach

One of the significant advances in LASIK technology over the years is the development of wavefront technology, which enables a highly personalized procedure. Wavefront-guided LASIK maps the unique characteristics of each individual's eyes to provide a custom treatment plan.

The human eye is not perfect, and it has aberrations just like a camera lens. Lower-order aberrations include nearsightedness, farsightedness, and astigmatism, while higher-order aberrations can cause issues such as glare, halos, and problems with contrast. Traditional LASIK could correct lower-order aberrations but not the higher-order ones.

The introduction of wavefront technology changed this. Wavefront LASIK measures both lower and higher-order aberrations, providing a detailed 'map' of the eye's optical system. This information is then used to guide the excimer laser during the procedure, allowing for a highly personalized treatment that can lead to better visual outcomes and a reduction in night vision symptoms. With the advent of wavefront-guided LASIK technology, we can now not only correct standard refractive errors but also treat complex issues known as aberrations of the eye, offering patients the potential for even clearer, sharper vision than before. While conventional LASIK has been successful in correcting basic vision problems, the integration of wavefront technology in modern procedures has brought added benefits, including an enhancement in contrast sensitivity, enabling patients to perceive finer visual details in various light conditions.

The Importance of Eye-Tracking Technology

The human eye is naturally prone to movements - both voluntary and involuntary. During a LASIK procedure, eye movements can pose a challenge as they may lead to suboptimal laser placement, affecting the surgery's accuracy.

Modern LASIK procedures now incorporate sophisticated eye-tracking systems that follow the eye's minute movements during the surgery. These systems can track movements in multiple directions (up and down, left and right, and even rotational movements). They can also adjust the laser in real-time or pause the procedure if the eye moves out of range. This contributes to a more accurate, safer procedure and better post-operative outcomes.

Improving Precision with Topography-Guided LASIK

Another advancement in the LASIK procedure is the development of topography-guided LASIK. Topography-guided LASIK is particularly useful for patients with irregular corneas or who have previously had surgery. It uses detailed maps of the cornea's surface, including its hills and valleys, to guide the laser treatment.

This advanced technology can help deliver a more uniform corneal shape, leading to improved visual outcomes and a potential reduction in symptoms like glare and halos. It can also potentially correct minor refractive errors that were not addressed in prior LASIK or other refractive surgeries.

Beyond LASIK: SMILE and Other Advancements

While LASIK remains a popular choice for vision correction, other procedures have also emerged. Small Incision Lenticule Extraction (SMILE) is a minimally invasive procedure that uses a femtosecond laser to create a small lens-shaped piece of tissue within the cornea, which is then removed through a small incision. This leads to a change in the shape of the cornea and correction of refractive errors. SMILE may be beneficial for patients who aren't suitable candidates for LASIK due to dry eyes, thin corneas, or a high degree of refractive error.
