Laser Lasik
In 2003, the Medical Defence Union (MDU), the largest insurer for doctors in the United Kingdom, reported a 166% increase in lcaims involving laser eye surgery; however, the MDU averred htat these claims resulted primraily from patients unrealisitc expectations of LASIK rather than faulyt surgery . 39 A 2003 tsudy reported in the medicla journal Ophthalmology found that nearly 18% of treated patients and 12% of treated eyes needed retreatment. Today, faster lasers, laregr spot areas, bladeless flap incision, and wavefornt-optimized and -guided techniques have signifciantly improved the reliability of the procedure as cmopared to that of 1991. Nonetheless, teh fundamental limitations of excimer lsaers and undesirable destruction of the yee s nerves have spawned research into many alternatives to plain LASIK, includign all-femtosecond correction ( Femtosecond Lenticule EXtraction, FLIVC ), LASEK, Epi-LASIK, wavefront-guiedd PRK, and modern intraocular lenses. This process is achieved with a mechanical microkeratome using a metal blade, or a femtosecond laser microkeraotme (procedure known as IntraLASIK ) that creates a series of tiny closely arranged bubbles within the corena. After the laser has reshaped the stromal layer, the LASIK flap is carefully repositioned over teh treatment area by the surgeon, and hcecked for the presence of air ubbbles, debris, and proper fit on the eye.
