PURPOSE To compare the long-term results (9 years) of LASIK in one eye and phakic intraocular lens (implantable contact lens [ICL]) implantation in the fellow eye of the same patient. METHODS A patient with high myopia underwent LASIK with a MEL 60 excimer laser in one eye (spherical equivalent refraction -9.75 diopters [D], 5-mm optical zone with no transition zone) and phakic intraocular le...

PURPOSE The aim of this study was to evaluate and compare night vision and low-luminance contrast sensitivity (CS) in patients undergoing implantation of phakic collamer lenses or wavefront-optimized laser-assisted in situ keratomileusis (LASIK). PATIENTS AND METHODS This is a nonrandomized, prospective study, in which 48 military personnel were recruited. Rabin Super Vision Test was used to ...

BACKGROUND/AIM Retinal nerve fibre layer thickness (RNFLT), as measured with scanning laser polarimetry using the fixed angle corneal polarisation compensator (SLP-F), has been found to be reduced after uncomplicated laser assisted in situ keratomileusis (LASIK) compared to the pre-LASIK measurement. Since this virtual RNFLT thinning is attributed to the corneal changes induced by the LASIK, th...

Multiple posterior segment complications can occur after LASIK. Posterior vitreous detachment, macular holes, retinal hemorrhages, retinal detachment, and several other complications have been described. A case of posterior vitreous detachment with epiretinal membrane in a young adult after LASIK is reported. LASIK surgeons must be aware of the possibility of posterior segment complications aft...

PURPOSE To evaluate the safety and efficacy of laser in situ keratomileusis (LASIK) compared to photorefractive keratectomy (PRK) for the correction of low or moderate myopia (-0.50 to -6.00 D) at 6 months after surgery. METHODS The study population comprised a non-randomized consecutive series of 622 eyes of 392 patients who were treated with the Nidek EC-5000 excimer laser. LASIK was perfor...

PURPOSE To characterize the early ocular-surface changes or tear inflammatory-mediators levels following small-incision lenticule extraction (ReLEx smile) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS Forty-seven myopic subjects were recruited for this prospective study. Fifteen underwent ReLEx smile and thirty-two underwent FS-LASIK. Corneal fluorescein (FL)...

PURPOSE To evaluate the current United States Food and Drug Administration (FDA) recommendations regarding laser in situ keratomileusis (LASIK) surgery in patients with collagen vascular diseases (CVD) and assess whether these patients make appropriate candidates for laser vision correction, and offer treatment recommendations based on identified clinical data. METHODS A literature search was...

The femtosecond laser (FS) is the most interesting technical de velopment in laser refractive surgery during the last few years. This technique was developed to create flaps for laser in situ keratomileusis (LASIK). The FS is a focusable infrared (1053 nm) laser that uses ultrafast pulses in the 100-femtosecond (100 x 10 second) range. The laser delivers closely spaced spots that can be focused...

PURPOSE To evaluate changes induced by standard laser in situ keratomileusis (LASIK) for hyperopia on total and corneal optical quality. METHODS Total and corneal aberrations were measured before and after standard hyperopic LASIK in 13 eyes (preoperative spherical equivalent refractive error +3.17 +/- 1.10 D). The Chiron Technolas 217C laser with PlanoScan was used. Total aberrations (measur...
