VISUAL AND REFRACTIVE OUTCOMES WITH A NEW TOPOGRAPHY-INTEGRATED WAVEFRONT-GUIDED LASIK PROCEDURE. Curr Eye Res. 2020 Sep 09;: Authors: Uceda-Montañés A, Rogers M, Piñero DP Abstract PURPOSE: To evaluate the clinical outcomes of laser in situ keratomileusis (LASIK) using a new approach for the calculation of the ablation profile based on wavefront vertexing from pupil plane to corneal. METHODS: One hundred eyes of 50 patients (age, 21-41 years) with low and moderate myopia were enrolled in this prospective case series. All of them underwent topography-integrated wavefront-guid...

AbstractPurpose of ReviewIn this article, we review the early experience with small incision lenticule extraction (SMILE) in the USA as well as recent international data. We address long-term experience, new techniques, optimization of settings, corneal biomechanics, and comparison with other refractive surgical procedures.Recent FindingsDespite promising early experience, US refractive surgeons have adopted the SMILE procedure slowly, owing in part to limitations on energy settings that have impacted early visual recovery. Outside of the USA, advances in parameters and techniques have driven improved early and long-term o...

Abstract PURPOSE: To determine if the manifest sphero-cylindrical residual refractive error, at various time points over a 12-month postop period after laser in situ keratomileusis (LASIK) was associated with patient age at time of surgery. METHODS: Patients with moderate to high hyperopia (3.00-7.00 DS) and astigmatism ⩽2 DC underwent LASIK using Wavelight Allegretto Eye Q (400 Hz). Treatments were centered on corneal vertex, flaps were made with Moria M2 mechanical microkeratome. Pre-and postoperative uncorrected and corrected distant visual acuity, best corrected spherical equivalent...

The goal of laser vision correction (LVC) is to eliminate or reduce the need for glasses and contact lenses. LVC treats three basic refractive errors: myopia (nearsightedness), astigmatism (blurring of vision due to non-spherical shape of the eye), and hyperopia (farsightedness). During an LVC procedure, the cornea — the clear dome on the surface of the eye — is reshaped in order to correct the refractive error. The different techniques to perform LVC are laser in situ keratomileusis (LASIK), phototherapeutic refractive keratectomy (PRK), and small incision lenticule extraction (SMILE). LASIK and PRK LASIK, the...

CONCLUSIONS: Regarding the visual acuity outcomes, there may be no difference between LASIK with mechanical microkeratome and LASIK with femtosecond laser. Dry eye and diffuse lamellar keratitis are likely adverse events with mechanical microkeratome and femtosecond laser, respectively. The evidence is uncertain regarding corneal haze and epithelial ingrowth as adverse events of each intervention. The limited number of outcomes reported in the included trials, some with potentially significant risk of bias, makes it difficult to draw a firm conclusion regarding the effectiveness and safety of the interventions investigated...

AbstractPurposeThe aim of this study is to report our results of toric intraocular lens (IOL) implantation in patients with asymmetric astigmatism, its efficacy and safety in reducing the refractive cylinder.MethodsThis is a retrospective cohort study. Patients with asymmetric astigmatism and non-progressive corneal ectasia, unable to fit hard contact lenses, with poor-corrected visual acuity or unsatisfactory spectacles-corrected visual acuity, underwent cataract surgery with toric IOL implantation. The choice of lens was individually after optical biometry examination. All surgeries were performed by a single surgeon, wi...

ConclusionExcimer laser vision correction among ophthalmologists in Saudi is much higher than the market penetration in the general population reported in other countries. Most of the ophthalmologists who underwent the procedure were satisfied with the outcome.

Comparison of 9.0 and 9.2 mm Flap Diameter Options of Femtosecond Laser In-Situ Keratomileusis for Hypermetropia and Hypermetropic Astigmatism. J Ophthalmol. 2019;2019:5907645 Authors: Ozulken K, Ilhan C Abstract Aim: To compare the postoperative one-year outcomes of asphericity (Q) and high order aberration (HOA) values of 9.0 and 9.2 mm diameter flap groups in hypermetropia and hypermetropic astigmatism subjects who underwent femtosecond laser in-situ keratomileusis (LASIK). Materials and Methods: The study included 68 eyes of 34 patients. A femtosecond laser platform (Allegrato Wav...
