Evolution of excimer laser corneal surgery
Journal of Cataract and Refractive Surgery, 1989Interest in the potential of the excimer laser for refractive surgery was generated by a series of experiments performed in IBM's T.J. Watson laboratories. The development of photoablative decomposition was applied to corneas with immediate implication for corneal refractive control.

Microbial Keratitis after Corneal Laser Refractive Surgery
Future Microbiology, 2011Corneal laser refractive surgery is increasingly being performed on patients with the aim of improving unaided vision. Most candidates for surgery have excellent spectacle- or contact lens-corrected vision. Although microbial keratitis following refractive surgery is a rare complication, and usually has a good visual outcome, it can be sight ...

New laser methods have introduced new possibilities and partly replaced traditional methods in corneal surgery. Femtosecond lasers have traditionally been used to replace the surgeons' knife in corneal refractive surgery and corneal transplantation. Excimer laser has been used from the beginning of 1990 for the reshaping of cornea. With the development

Corneal Inflammation Following Corneal Photoablative Refractive Surgery With Excimer Laser
Survey of Ophthalmology, 2013Millions of surface ablation excimer laser surgeries are performed worldwide. The normal cornea, when photoablated, reacts in a way specific to this process. The fundamentals of this biological reactivity are based on the normal structure of the photoablated cornea and on the energy delivered by the laser.

All laser cataract surgery compared to femtosecond laser phacoemulsification surgery: corneal trauma
International Ophthalmology, 2016The aim of this study was to evaluate corneal tissue trauma after femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification (femtophaco surgery) compared to FLACS and nanolaser emulsification (all laser surgery). This is a prospective nonrandomized clinical study conducted at the Ophthalmology Clinic, University "G.

Corneal refractive surgery with femtosecond lasers
IEEE Journal of Selected Topics in Quantum Electronics, 1999We investigated the use of ultrashort pulsed (femtosecond) laser technology in corneal refractive surgery. When compared to longer pulsewidth nanosecond or picosecond laser pulses, femtosecond laser-tissue interactions are characterized by significantly smaller and more deterministic photodisruptive energy thresholds, as well as reduced shock waves and

Finite element simulations of laser refractive corneal surgery
Engineering with Computers, 2008We setup a mechanically based finite element model to evaluate the change in the shape of the human cornea induced by ablation of stromal tissue. By considering the deformability of the cornea, the model computes the change of the dioptric power resulting from ablative laser surgery.

Laser Corneal Refractive Surgery: An Update
2013Lamellar corneal surgery for the correction of refractive errors has been evolving for more than 60 years. LASIK (laser-assisted in situ keratomileusis) is a well-known procedure for correction of different refractive defects as myopia, hyperopia and astigmatism.
