This article explores the intriguing journey of its invention, tracing the history of laser eye surgery through significant milestones and advancements. We will delve into the evolution of techniques, focusing on LASIK, PRK, and other modern procedures that have transformed the landscape of refractive surgery.

The Early Beginnings Of Laser Eye Surgery

The story of laser eye surgery begins with the development of laser technology in the 1960s, which laid the foundation for innovative approaches to vision correction. These advancements set the stage for the developments that followed. Theodore Maiman’s invention of the first laser in the early 1960s laid the foundation for laser eye surgery, setting the stage for future advancements. This revolutionary device emitted light through stimulated emission, setting the stage for various applications, including eye surgery. However, it wasn’t until the 1980s that lasers were harnessed specifically for vision correction.

In 1983, researchers developed the excimer laser, an ultraviolet laser that could precisely remove thin layers of corneal tissue without damaging the surrounding area. This breakthrough was crucial to the evolution of laser eye surgery, introducing procedures specifically designed to correct refractive errors.

When Was The Laser Vision Correction Procedure Invented?

The beginning of laser-guided corrective eye surgery can be traced back to the early 1980s, particularly with the introduction of excimer laser technology. The first successful laser eye surgery in 1987 achieved a significant milestone in ophthalmology, paving the way for future advancements.

Chronology Of Laser Eye Surgery History

Appreciating the evolution of laser eye surgery relies on a thorough understanding of its chronological development. The following chronological overview highlights key milestones in the development of laser vision correction.

• 1964: Dr José Ignacio Barraquer introduced the keratomileusis and keratophakia techniques for reshaping the cornea.
• 1974: Dr Svyatoslav Fyodorov developed Radial Keratotomy (RK) surgery in the USSR.
• 1981: Rangaswamy Srinivasan at IBM discovered that an excimer laser can etch living tissue with precision.
• 1987: Stephen Trokel at Columbia University performed the first Photorefractive Keratectomy (PRK) procedure using an excimer laser.
• 1988: Dr Marguerite McDonald performed the first successful PRK procedure.
• 1995: The FDA approved PRK in the United States.
• 1998: LASIK eye surgery became FDA-approved in the United States.

The History Of LASIK

Since its inception, LASIK surgery has emerged as a popular laser eye surgery. Understanding its historical context provides insight into its significance and widespread adoption. LASIK (Laser-Assisted In Situ Keratomileusis) emerged in 1990, building on earlier techniques and utilising excimer laser technology to reshape the cornea. This innovative procedure allowed for greater precision and less postoperative discomfort than its predecessors, quickly becoming one of the preferred refractive surgeries worldwide. During the LASIK treatment, a corneal flap is made using either a microkeratome or an advanced femtosecond laser. This flap then gets lifted to expose the underlying corneal tissue, which is reshaped using an excimer laser. The result is a sculptured cornea that effectively corrects refractive errors like myopia, hyperopia, and astigmatism.

LASIK quickly gained popularity following its introduction due to its quality and rapid recovery time. By the mid-1990s, LASIK procedures were being performed in increasing numbers, significantly impacting the market for vision correction.

The Evolution Of PRK Before LASIK

Before LASIK became the go-to procedure for laser vision correction, PRK paved the way by providing an optimal solution for many patients. Photorefractive Keratectomy (PRK), first performed in the late 1980s, was the precursor to LASIK. This technique involved the direct application of the excimer laser to the cornea’s surface, effectively flattening it to correct refractive errors. Unlike LASIK, PRK does not include the creation of a corneal flap. The first PRK surgery was conducted in 1988, demonstrating promising results for patients with refractive errors. However, the recovery process was longer and often involved more discomfort than LASIK due to the absence of a protective flap.

PRK provided clear advantages over earlier procedures like radial keratotomy (RK), which entailed creating radial incisions in the cornea to change its curvature. While RK was an innovative approach, it often led to complications and inconsistent results. PRK provided a more predictable outcome without the risks associated with incisions.

Comparing PRK And LASIK

With the rise in popularity of LASIK, it became crucial to compare it with PRK to grasp its individual benefits and drawbacks. This section explores the key differences between these two pivotal procedures. To evaluate the differences between PRK and LASIK effectively, it is important to look at their fundamental techniques and outcomes.

PRK Laser Eye surgery feature

Feature	PRK	LASIK
Flap Creation	No	Yes (hinged flap)
Recovery Time	Longer (several days to weeks)	Shorter (24-48 hours)
Postoperative Discomfort	More discomfort initially	Less discomfort
Ideal Candidates	Thin corneas, irregularities	Most refractive errors

PRK surgery has helped countless individuals achieve better vision by providing a strong option for those not candidates for LASIK due to thin corneas or other corneal irregularities. This technique laid the groundwork for further innovations in laser vision correction.
