IntraLase femtosecond laser vs mechanical microkeratomes in LASIK for myopia: a systematic review and meta-analysis, J Refract Surg.2012;28(1):15-24.Chang JS. First, it avoids the risk associated with the corneal flap (e.g., free flap, broken flap, and button flap) made by microkeratome in LASIK.

Femtosecond laser-assisted suture less anterior lamellar keratoplasty (FALK), first described in 2008, has been reported to be safe, effective, and stable.

Comparison of the IntraLase femtosecond laser and mechanical microkeratomes for laser in situ keratomileusis. Peripheral intracorneal implantation has been permitted to correct low to moderate astigmatism and myopia and keratoconus by Food and Drug Administration (FDA). Contact our London head office or Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing.Laser technology is used in many basic and clinical disciplines and specialties, and it has played an important role in promoting the development of ophthalmology, especially corneal refractive surgery. The femtosecond laser for ophthalmology works at 1053-nm wavelength with a very short pulse duration of 10The concept of the lamellar refractive procedure was first introduced by Barraquer in the early 1960s. The first is the very sophisticated femtosecond laser used to create high precision, thin corneal flap , and then, the excimer laser is used to reshape the underlying corneal tissue or stroma. Am J Ophthalmol 2006;141(5):189-197.Patel SV, Maguire LJ et al. It changes the anterior corneal surface curvature, cornea refractive index, and depth of focus by placing a small inlay of suitable biocompatible material within the stroma. Lu Xiong conducted a study on the clinical outcomes in low to moderate myopia after LASEK treatment, and the results showed that LASEK has a good effect and better postoperative experience compared with PRK.According to the principles of LASEK, it not only optimizes PRK but also avoids some disadvantages of laser lamellar corneal refractive surgery such as LASIK. More than 55% of all LASIK procedures in 2009 were performed with FS laserAs described above, FS laser has a lot of advantages over microkeratome LASIK and is gaining more and more acceptance worldwide.

Increasingly, researchers have focused on improving postoperative visual quality.

FS laser has a wide range of applications in corneal refractive surgeryThe suction ring is centered over the pupil and suction is applied once proper centration of the ring has been ensured and verified. Despite having certain limitations and complications, femtosecond lasers are promising in ophthalmology. A spatula is carefully passed across the flap starting at the hinge and sweeping inferiorly to lift the flap for excimer laser ablation. The femtosecond laser allows thin and uniform flaps, which improves the stability, safety, and precision of the flaps. Femtosecond applications for anterior segment surgery. FS lasers hold great promise and its applications are continuing to evolve and expand in ophthalmology. 2007;114(8):1482-1490. The accuracy is 5 μm, allowing high precision in ophthalmic operations .

Both excimer and femtosecond laser technology will serve for better human health as long as we apply it appropriately.© 2016 The Author(s). The procedure involves concentric intrastromal ring creation in the central portion of the cornea at different corneal depths (between the Bowman’s and Descemet’s boundaries). 2007;23(6):555-558.Lim T, Yang S et al. It is important to achieve complete applanation of the cornea to avoid an incomplete flap or other flap related complications. J Refract Surg. 1997;104(7):1067-1078.Abbey A, Ide T, Kymionis GD, Yoo SH Femtosecond laser-assisted astigmatic keratotomy in naturally occurring high astigmatism. 2012 Dec;28(12):912-20. The femtosecond laser can be programmed to create corneal channels at a specific depth and orientation with high predictability and precision to allow safer insertion of Intacs segments.

J Refract Surg. Curr Opin Ophthalmol. Even though the flap of Epi-LASIK is closer to corneal natural state, the postoperative biomechanical change of the corneal flap and the effect on corneal healing are yet to be determined [Transepithelial photorefractive keratectomy (Trans-PRK), where both the epithelium and stroma are removed in a single step, is a relatively new procedure of laser refractive error correction. J Refract Surg. The crucial technique is selective endothelial transplantation. The patients studied received many benefits from the excimer laser and femtosecond laser technologies and were satisfied with their clinical outcomes.In the field of ophthalmology, laser technology is used in many basic and clinical disciplines and specialties. Manual LASIK flap creation is effective, however, complications like flap folds, plastic mask particles in the surgical interface, epithelial ingrowth, and ectasia (if the flap is cut too deep) have been documented.Copyright © 2020 EyeWorld News Service. The latest laser system delivers more laser spots per second so as to reduce the treatment time [Compared with other corneal refractive surgeries, Trans-PRK has the advantages of no chemical toxicity or mechanical damage, no corneal incision, no negative pressure suction, and less risk of infection, and it avoids the potential damage caused by negative pressure suction.Trans-PRK was considered as a kind of minimally invasive surgery for its optimal safety.

As with any other technology, competition will likely bring down the cost of the equipment making the price per case less expensive. IntraCor surgery is promising in the field of presbyopia correction [To correct low to high astigmatism, astigmatic keratotomy (AK) is performed. 2013 Mar;41(2):180-6.Durrie DS, Kezirian GM.
