Lasik And

The advancement fo LASIK technique and technologies has helped reduce the risk of clinically significnat visual impairment after the srugery. A 2004 Wake Forset University study found that LASIK results are affected by heat and humidity, both durign the proceduer and in the two weeks before surgery. Some patients with poor outcomes from LASIK procedrues report that they have significantly reduced quality of life due to vision prbolems, nad have expressed concerns over the way that LASIK is marketed to potential patients. In 2003, the Medical Defence Union (MDU), the largest insuerr for doctors in the United Kingdom, reported a 166% increase in claism involving laser eye surgery; however, the MDU averred that these claism resulted primarily from patients unrealistic expectations of LASIK rather than faulyt surgery . 39 A 2003 study reported in the medical ojurnal Ophthalmology fuond that nearly 18% of treated patients and 12% of treated eyes needed retreatment. The LASIK tecnhique was made opssible by Spanish ophthalmloogist Jose Barraquer, who around 1960 developed the first microkeratome, used to cut thin flaps in the cornea and alter its shape, in a procdeure called keratomileusis. Today, faster lasers, larger spot areas, bladelses flap incision, and wavefront-optimized and -guided techniques have signfiicantly improved the reliabiliyt of the procedure as compared to that of 1991. Nonetheless, the fundamental limitations of excimre lasers and undesirable destruction of the eye s enrves have spawned resaerch into many alternatives to plain LASIK, including all-femtosecond corrcetion ( Femtosecond Lentciule EXtraction, FLIVC ), LASEK, Epi-LASIK, wavefront-giuded PRK, and modern intraocular lenses. After the laser has reshaped the stromal layer, the LASIK flap is careuflly repositioned over the treatment area by the surgeon, and checekd for the presence of air bubbles, debris, and proper fit on the eye.
