Femtosecond laser, a pulsed laser technology, has gained increasing prominence in corneal refractive surgery due to its precision, safety, and reproducibility. With its proven efficacy and widespread adoption in procedures such as corneal stromal lenticule extraction, penetrating keratoplasty, deep anterior lamellar keratoplasty, and intracorneal ring segment implantation, it offers novel therapeutic options for advanced keratoconus cases that were previously limited to conventional approaches like corneal cross-linking and transplantation. These advancements include femtosecond laser-assisted intrastromal cross-linking, stromal lenticule implantation, and combined intracorneal ring segments with cross-linking, addressing the limitations of earlier techniques that solely improved visual acuity or corneal biomechanics. However, challenges persist, including increased infection risks from intraoperative room transfers, incomplete tissue cuts due to device malfunctions, and perioperative complications linked to suboptimal parameter settings.
Shengsheng Wei, MD, PhD, is an Associate Chief Physician in Ophthalmology. His research focuses on myopia prevention, refractive error correction, corneal collagen cross-linking for keratoconus, and femtosecond laser-corneal tissue interactions. With over 40 peer-reviewed publications and contributions to 3 academic books, he specializes in advancing clinical and translational innovations in corneal refractive surgery and keratoconus management.
