Update on contraindications in laser corneal refractive surgery
Archivos de la Sociedad Española de Oftalmología (English Edition), 2023More than 25 years of experience with refractive surgery techniques (since the FDA [Food and Drug Administration] of the United States approved the use of the excimer laser in the remodeling of the cornea in 1995), added to the technological advances in ophthalmology (femtosecond laser, topography-guided ablation, anterior segment imaging systems) and ...

Femtosecond laser-assisted corneal surgery
Current Opinion in Ophthalmology, 2010A look at the recent advances in corneal transplantation surgery using the femtosecond laser technology.The femtosecond laser uses near-infrared light to create photodisruption, a process that allows corneal tissue to be cut at precise depths and in various patterns.

Femtosecond laser-assisted corneal surgery
Current Opinion in Ophthalmology, 2007The femtosecond laser has potentially improved the safety and precision of creating corneal flaps in laser in situ keratomileusis (LASIK). This review focuses on recent advances in applying femtosecond laser technology to other corneal procedures.The femtosecond laser is capable of cutting tissue at various depths and patterns with minimal collateral ...

Modeling the biomechanics of laser corneal refractive surgery
Journal of the Mechanical Behavior of Biomedical Materials, 2023We present a finite element model of the human cornea used to simulate corneal refractive surgery according to the three most diffused laser procedures, i. e., photo-refractive keratectomy (PRK), laser in-situ keratomileusis (LASIK) and small incision lenticule extraction (SMILE). The geometry used for the model is patient-specific in terms of anterior

Pupil size and corneal laser surgery
Current Opinion in Ophthalmology, 2006The role of scotopic pupil size as a factor in predicting night vision complaints is controversial. This review summarizes reports in the literature, some that have found and some that have failed to find a correlation with scotopic pupil size and night vision complaints.Pupil-measuring devices are discussed along with informed consent issues and ...

Refractive corneal surgery with lasers
Current Opinion in Ophthalmology, 1996Laser refractive surgery is on one hand in a phase of consolidation regarding the routine treatment of mild to moderate myopia by means of spheric excimer laser photorefractive keratectomy. On the other hand, exciting new developments are taking place in the field of high myopia, myopic astigmatism, and new alternative lasers.

Applications for the femtosecond laser in corneal surgery
Current Opinion in Ophthalmology, 2007Little has changed in how corneal surgery, particularly full-thickness penetrating keratoplasty, has been performed since the introduction of the operating microscope and microsurgery more than 40 years ago. The introduction of IntraLase Enabled Keratoplasty represents the first true advancement in corneal surgery in that time.

Duodecim; laaketieteellinen aikakauskirja, 2018
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

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.

Applications of the femtosecond laser in corneal refractive surgery
Current Opinion in Ophthalmology, 2011The femtosecond laser has become a rapidly and widely adopted technology for surgeons performing refractive surgery. With the advances in femtosecond lasers, clinical outcomes and safety with their use have improved. The purpose of this review is to outline the current surgical applications of the femtosecond laser in corneal refractive surgery.Many ...
