1. Jose Ignacio Barraquer (microkeratome)
Jose Ignacio Barraquer’s contribution to modern refractive surgery is pivotal. He developed the microkeratome, a precise surgical instrument used to create a thin flap in the cornea. This innovation proved essential for the later development of LASIK. Prior to the microkeratome, reshaping the cornea to correct vision was a more invasive and less predictable procedure. Barraquer’s invention provided the necessary precision and control, enabling surgeons to access the underlying corneal tissue with significantly reduced risk. This laid the foundation for the precise and controlled corneal reshaping fundamental to LASIK.
Barraquers initial intention was not laser vision correction as we know it today. He used the microkeratome for a procedure called keratomileusis, which involved removing a thin slice of the cornea, reshaping it manually, and then re-implanting it. While this technique was innovative, it was complex and challenging. However, the microkeratome itself proved invaluable. Its ability to create a consistent, predictable corneal flap paved the way for subsequent advancements, specifically the integration of the excimer laser, which ultimately led to the development of LASIK.
Barraquer’s legacy lies in his foresight and ingenuity. While he didn’t invent LASIK in its final form, the microkeratome he developed was a critical stepping stone. Without the ability to create a precise corneal flap, the subsequent application of the excimer laser for refractive correction would not have been feasible. His contribution exemplifies how incremental advancements can lead to paradigm shifts in medical practice. The microkeratome’s precision and control remain integral to modern LASIK procedures, underscoring Barraquer’s lasting impact on the field of ophthalmology.

3. Gholam A. Peyman (flap concept)
Gholam A. Peyman’s contribution of the corneal flap technique represents a crucial link in the chain of innovations leading to modern LASIK. While earlier methods like photorefractive keratectomy (PRK) reshaped the cornea directly, they presented certain limitations, including slower healing and greater patient discomfort. Peyman’s concept of creating a thin, hinged flap in the cornea before applying the excimer laser addressed these challenges. This approach allowed for the reshaping of the underlying corneal tissue while preserving the protective outer layer, leading to faster healing, reduced post-operative pain, and improved visual recovery. This pivotal innovation bridged the gap between earlier refractive procedures and the precise, less invasive procedure now known as LASIK.
Peyman’s flap technique, combined with the excimer laser, provided a more controlled and predictable method for refractive correction. Creating the flap allowed surgeons to access the stroma, the part of the cornea responsible for the majority of refractive errors, with minimal disruption to the surface epithelium. This precise access enabled the excimer laser to reshape the cornea with greater accuracy, resulting in more predictable visual outcomes. The integration of the flap technique significantly improved the safety and effectiveness of refractive surgery, propelling the field forward and contributing directly to the widespread adoption of LASIK.
The development of LASIK is a testament to the collaborative nature of scientific progress.
