AIM To study the visual performance in eyes with interface haemorrhage during laser assisted in situ keratomileusis (LASIK). METHODS Case records of 20 patients, who had bleeding from the limbal vessels in one eye during LASIK (group 1) and uncomplicated surgery in the fellow eye (group 2) were studied. The parameters evaluated were uncorrected visual acuity (UCVA) best corrected visual acuit...

WAVEFRONT-guided photorefractive keratectomy (PRK) induces fewer higher-order aberrations than wavefrontguided LASIK, while the latter induces fewer higher order aberrations than conventional or optimised LASIK, suggest the preliminary results of two new studies presented at the XXIII Congress of the ESCRS. “In my practice, I employ wavefront guided technology in every patient that is eligible,...

PURPOSE To describe a cluster of Mycobacterium chelonae keratitis cases involving patients who underwent laser in-situ keratomileusis (LASIK) at a single refractive surgery center. DESIGN Descriptive case series of four patients and cohort study to identify disease associations. METHODS Examination schedules, diagnostic tests, and therapy were based on best medical judgment. Isolates from t...

PURPOSE To compare the results of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for myopia using a mixed-effects model. METHODS This comparative retrospective study was conducted in 1,127 eyes of 579 patients after LASIK and 270 eyes of 144 patients after PRK who had two or more postoperative follow-ups after 3 months. Uncorrected visual acuity (UCVA), best specta...

PURPOSE To determine the accuracy of Pentacam Scheimpflug system Holladay equivalent keratometry (K) readings (EKRs) in calculating intraocular lens (IOL) power after corneal refractive surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), and radial keratotomy (RK). SETTING Jules Stein Eye Institute, David Geffen School of Medicine at University of Calif...

CASE REPORT A male with cylindrical anisometropia secondary to retinal detachment (RD) surgery in the right eye (OD) was referred for contact lens (CL) fitting. His refraction was OD -1.25 -2.75 x 60 degrees VA 1.0 and OS +0.25 VA 1.2. He was complaining of diplopia with spectacles. Seven years prior to the RD surgery, he had undergone LASIK without complications. The diplopia was eliminated af...

LASIK (Laser-Assisted in SItu Keratomileusis) surgeries have been quite popular for treatment of myopia (nearsightedness), hyperopia (farsightedness) and astigmatism over the past two decades. In the past decade, over 10 million LASIK procedures had been performed in the United States alone with an average cost of approximately $2000 USD per surgery. While 99% of such surgeries are successful, ...

BACKGROUND The purpose of this study was to determine the accuracy of intraocular pressure (IOP) measurement after laser in situ keratomileusis (LASIK) or epithelial laser in situ keratomileusis (Epi)-LASIK using Goldmann applanation tonometry, air puff tonometry, ocular response analyzer corneal compensated IOP (ORA IOPcc) and Pentacam corrected IOP. METHODS A prospective comparative clinica...

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...
