The generation of light pulses around 100 fs was made possible by the introduction of the colliding pulse mode-locking technique [ 11. The specially designed laser produced femtosecond light pulses in the spectral range around 620 nm. The advanced understanding of the pulse shaping process and the introduction of an intracavity compensation of dispersion allowed the stable generation pulses bet...

PURPOSE To evaluate femtosecond laser lens fragmentation and anterior capsulotomy in cataract surgery. METHODS Anterior capsulotomy and phacofragmentation procedures performed with an intraocular femtosecond laser (LenSx Lasers Inc) were initially evaluated in ex vivo porcine eyes. These procedures were then performed in an initial series of nine patients undergoing cataract surgery. In addit...

Purpose: The purpose of this study was to evaluate a new procedure aimed at lengthening the palpebral fissure to facilitate femtosecond laser-assisted cataract surgery in patients with small eyes. Method: A quick procedure using the CO2 laser was adapted for patients with small eyes undergoing laser-assisted cataract surgery using the Catalys system. The UniPulse CO2 laser (Nidek) was used for ...

PURPOSE To report a case of rainbow glare following femtosecond laser-assisted LASIK (femto-LASIK) with the Wavelight FS-200 femtosecond laser (Alcon Laboratories, Inc., Fort Worth, TX). METHODS A patient was treated bilaterally for myopia with femto-LASIK using the FS-200 femtosecond laser. Postoperatively, he complained of rainbow glare in his right eye. RESULTS Three months postoperative...

PURPOSE To discuss intraoperative and postoperative femtosecond laser-assisted LASIK flap complications and their management. METHODS Review of published literature. RESULTS Flap creation is a critical step in LASIK. The femtosecond laser has improved the overall predictability and safety of the lamellar incision, but complications can still occur during or after flap creation. Although man...

Recent research and development on the femtosecond laser has shown that it is a powerful tool for high precision micromachining. However, femtosecond laser-material interaction is fast and complex due to its ultrashort pulse duration. As the laser-induced plasma possesses useful information to understand the physical mechanism of laser processing, we investigate the optical emission during femt...

The use of the femtosecond laser in ophthalmic surgery over the last decade has resulted in the development of innovative procedures. The ultra-short infrared laser pulses of the femtosecond laser can be applied precisely and predictably with minimal collateral tissue damage, making it an ideal tool for highly precise ophthalmic surgery. Flap creation in laser in situ keratomileusis (LASIK) is ...

OBJECTIVE To assess efficacy, safety, predictability, stability, and changes in corneal higher-order aberrations (CHOAs) and contrast sensitivity (CS) after a femtosecond laser for LASIK and standard LASIK for myopia. DESIGN Prospective, randomized, comparative clinical study. PARTICIPANTS Two hundred eyes of 100 consecutive patients who underwent LASIK treatment using the VISX S2 laser sys...
