LASIK eye surgery is typically carried out with Excimer laser. LASIK治療眼科手術通常是進行準分子激光。 Excimer lasers are extremely precise, but they are also costly and expensive to maintain, which primarily accounts for the high cost of LASIK surgery.準分子激光器是非常精確，但他們也是昂貴的和昂貴的維持，這主要是佔成本高昂， LASIK手術。

Researchers are looking into the possibility of using a new type of lasers for LASIK surgery and other laser vision correction procedures.研究人員正在研究是否有可能把使用一種新型的激光LASIK手術和其他激光視力矯正程序。 One such laser is a solid-state refractive laser called the Pulzar Z1, developed by CustomVis (Perth, Australia). 1 ，如激光是一種固體激光屈光狀態稱為pulzar z1 ，開發customvis （珀斯，澳大利亞） 。

The Pulzar solid-state laser uses a slightly different wavelength of light to reshape the cornea, compared to the excimer laser (213 nm vs 193 nm).該pulzar固體激光器的用途略有不同波長的光來重塑角膜相比，準分子激光（ 213納米與193納米） 。 Because these longer wavelength beams are closer to the peak absorption of corneal collagen, it's possible that the solid state laser may be more efficient at ablating corneal tissue than the excimer laser and may be able to created smoother ablations.因為這些波長較長的光束接近山頂的吸收角膜膠原，它的可能是固體激光器，可更有效地在消融角膜組織，比準分子激光和可以創造順暢ablations 。 The ablations performed by the solid-state laser also appear to be less affected by the amount of water in and on the cornea during surgery.該ablations由固體激光器似乎也少受影響的耗水量，並在對眼角膜手術過程中。

The solid-state instrument does not require toxic gases to operate, it's more energy efficient than an excimer laser, and it requires less maintenance.固體國家儀器不需要有毒氣體的運作，它的更大的能量，效率比一準分子激光，它需要較少的維修工程。

In a small scale study with Pulzar solid-state laser for treatment of high degree of astigmatism, CustomVis found:在一個小規模的研究與pulzar固體激光治療高度散光， customvis發現：
1. 1 。 100% of the eyes were 20/30 or better 100 ％的眼睛20/30或更好
2. 2 。 80% of the eyes were 20/25 or better 80 ％的眼睛20/25或更好
3. 3 。 30% of the eyes were 20/20 30 ％的眼睛20/20

"There were no complications, and patient satisfaction was very high," reported CustomVis clinical manager Tarak A. Pujara, MD “有，無並發症，病人滿意度非常高， ”報告customvis臨床經理tarak答： pujara ，醫學博士

The Pulzar Z1 solid-state laser is not yet approved by the US Food and Drug Administration (FDA) for use by LASIK surgeons in the US, but CustomVis may start the FDA approval process by the end of this year or in early 2008, according to Dr. Pujara.該pulzar z1固體激光器是尚未獲得批准，由美國食品和藥物管理局（ FDA ）使用的LASIK術後外科醫生，在美國，但customvis 5月開始FDA的批准進程，今年年底或2008年年初，根據博士pujara 。

Notes:註釋：
1. 1 。 LASIK is an acronym for laser assisted in situ keratomileusis, a kind of laser eye surgery designed to change the shape of the cornea to eliminate or reduce the need for glasses and contact lenses in cases of severe myopia ( nearsightedness ). LASIK治療是一個縮寫，激光輔助角膜原位磨鑲術， 1種激光眼科手術旨在改變形狀的眼角膜，以消除或減少需要眼鏡及隱形眼鏡，在案件嚴重近視（遠視） 。

2. 2 。 Excimer laser procedure is a key part of LASIK (Laser in Situ Keratomileusis) and PRK (Photorefractive Keratectomy), both of which permanently re-shape the cornea using an ultraviolet excimer laser.準分子激光的程序是一個關鍵的一部分， LASIK術後（激光角膜原位磨鑲術）和PRK治療（屈光性角膜切削術） ，這兩項研究永久重新塑造角膜使用紫外線準分子激光。 The hallmark of this heatless, pulsed laser etching of tissue is the absence of thermal damage, which means living tissue can heal with virtually no scarring.的標誌，這熱，脈衝激光蝕刻的組織是沒有的熱損傷，這意味著生活的組織可以治愈，幾乎沒有疤痕。
