The field of ocular surgery has had a significant impact on medical laser
technology throughout the last four decades, and the reverse is also true. Because the eye,
cornea, lens, and vitreous body are optically transparent, it is much easier to deliver laser
energy at visible and near infrared (NIR) wavelengths at different focal depths through
these structures than through other types of tissue in the body. This allows for surgical
interventions to take place without opening or mechanically entering the eye, which is a
unique advantage of fs-Laser technology. Refractive corneal surgery, therapeutic cornea
treatments, and lens surgery were the original applications of fs-lasers. Additional novel
ophthalmic applications are also in the works. The most recent idea in laser systems is low
pulse energy and high pulse frequency. This allows for thermal tissue cutting with few side
effects since bigger numerical aperture focusing optics reduce the pulse energy needed for
optical breakdown. In the field of ophthalmic surgery, fs-laser technology has developed
into a highly accurate, dependable, and adaptable instrument during the last several
decades. Ergonomic and sturdy systems have become standard equipment in contemporary
operating theatres for eye surgery when coupled with ancillary technologies such as sterile
eye docking systems, optical coherence tomography (OCT) imaging, rapid laser scanning,
and sophisticated software. Global standards for fs-Laser-assisted cataract and corneal
surgery are now rather high.
