The term “excimer” is shorthand for “excited dimer.”. Excimer laser surgery has taken its place in the medical world as a reliable method that is safe which provides consistent results. In 1983, Stephen Trokel first started using the ArF (193 nm) excimer laser as a precise and safe tool of corneal shaping in calf eyes. Many different methods are available on the market that work with femtosecond lasers and/or excimer lasers. The goal of treatment in refractive surgery is the ablation of the eye cornea in order to achieve optimal refractive power. Introduction: In the field of ophthalmology, laser technology is used in many basic and clinical disciplines and specialities. An excimer laser corrects nearsightedness by flattening the cornea; it corrects farsightedness by making the cornea steeper. Principles and Practice . As a surgical tool, it enables pinpoint application of short, high-energy pulses to reshape the cornea while, at the same time, preventing collateral damage to the surrounding tissue.

He found that the excimer laser not only accurately ablated central corneal tissues but also did not do excessive damage to the peripheral corneal tissues. Refractive defects such as myopia, hyperopia or astigmatism can be corrected using this technology. Pathophysiology Of Focal Laser Laser energy removes unhealthy RPE cells which are then replaced by more viable RPE cells Photocoagulation stimulates the existing RPE cells to absorb more fluid. 2. Over the last 25 years LVC procedures using excimer lasers have become the most precise applications of such tools in ophthalmology, allowing highly effective surgery with almost total predictability and … Microlithography.

CNJ McGhee, HR Taylor, DS Gartry, SL Trokel, eds. The argon-fluoride atoms or ions are excited through the application of electrical energy. The excimer laser is then used to remove about 1% of the superficial stroma (5–6 microns, partway through Bowman’s membrane), which allows for stronger and smoother adhesion of the new epithelial layer when it grows back in. Investig. The femtosecond LASER used sometimes in corneal and cataract surgery. The authors outline and discuss a number of the more exciting applications of excimer lasers in ophthalmology.
