PURPOSE To report a successful case management of a retinal tear post-Laser in situ Keratomileusis (LASIK) and retreatment. RESULTS A patient with the history of ocular trauma underwent LASIK procedure for myopic astigmatism. Three months post-LASIK, she received additional excimer laser treatment for a symptomatic persistent central island. One month later; the patient experienced a flap tea...

BACKGROUND To compare changes in higher-order aberrations (HOAs) following small incision lenticule extraction (SMILE) and wavefront-guided femtosecond laser-assisted in situ keratomileusis (WFG FS-LASIK), and to investigate correlations between preoperative spherical equivalence (SE) and components of HOAs affecting visual quality. METHODS Sixty-five myopic eyes from 38 patients were enrolle...

Purpose To assess the predictive accuracy of simulation-based LASIK outcomes. Methods Preoperative and 3-month post-LASIK tomographic data from 20 eyes of 12 patients who underwent wavefront-optimized LASIK for myopia were obtained retrospectively. Patient-specific finite element models were created and case-specific treatment settings were simulated. Simulated keratometry (SimK) values and t...

The mainstay of treatment for those with hyperopic astigmatism who wish to bypass the need for glasses or contacts has traditionally been laser treatment. Both hyperopic laser in situ keratomileusis (LASIK) and photorefractive keratotomy (PRK) have been used to correct hyperopic astigmatism. Although LASIK can provide promising results for a portion of patients with hyperopic eyes, it becomes l...

tients are at risk for lagophthalmos and exposure-related keratitis. The post-LASIK neurotrophic status of these patients may further predispose them to infectious keratitis. The first case represents, to our knowledge, the earliest postLASIK human histopathologic finding (9 days post-LASIK). The neurotrophic cornea would certainly be a risk factor in the immediate postoperative period. The fir...

AIMS To determine the effect of intact corneal epithelium on stromal haze and myofibroblast cell formation after excimer laser surgery. METHODS Denuded epithelium alone, photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), or LASIK with denuded epithelium was performed in rabbit eyes. Postoperative anterior stromal haze was assessed employing a standard scale. Immunohistoc...

To investigate the incidence, culture results, treatment, and visual outcomes of infectious keratitis after laser in situ keratomileusis (LASIK) worldwide, the Cornea Clinical Committee of the American Society of Cataract and Refractive Surgery (ASCRS) contacted 8600 United States and international ASCRS members by e-mail and asked them to respond to a questionnaire about post-LASIK infectious ...

PURPOSE: To report persistent subepithelial haze in two patients following femtosecond LASIK associated with creation of a thin fl ap. METHODS: Subepithelial haze was assessed by slit-lamp photography, high-resolution Scheimpfl ug imaging, and corneal confocal microscopy. RESULTS: Two patients showed distinct subepithelial haze and reduced corrected distance visual acuity at 3 months after LASI...

AIM To assess the long term (1 year) effect of myopic and hyperopic LASIK on corneal sensation and innervation. METHODS 83 eyes of 43 patients having LASIK were evaluated. According to the preoperative spherical equivalent, the eyes were divided into three groups: group 1, myopia from -0.75 to -6.00 D; group 2, myopia from -6.25 to -11.50 D; and group 3, hyperopia from 1.25 to 5.00 D. Corneal...

BACKGROUND Laser in situ keratomileusis (LASIK) is the most common and popular procedure performed for the correction of refractive errors in the last two decades. We report a case of traumatic flap displacement with flap folding which occurred 3 years after LASIK was performed. Previous literature suggests that vision prognosis would be closely related to proper and prompt management of trauma...
