Ophthalmologe 2019 Mar;116(3):293-304

Univ.-Augenklinik Düsseldorf, Heinrich-Heine-Universität, Moorenstr. 5, 40225, Düsseldorf, Deutschland.

Astigmatism is the most frequent refractive error worldwide followed by hyperopia and myopia. Internal astigmatism has to be differentiated from external astigmatism. Furthermore, external astigmatism can be divided into "with the rule", "against the rule" and "oblique". Read More

Unwanted Astigmatism and High-order Aberrations One Year after Excimer and Femtosecond Corneal Surgery.

Optom Vis Sci 2018 Nov;95(11):1064-1076

Specialty Eye Hospital Svjetlost, Zagreb, Croatia.

Significance: Small incision lenticule extraction (SMILE) is advanced as the most minimally invasive and least traumatic corneal procedure for correcting refractive errors using a single laser. Although SMILE obtains similar results to femtosecond laser in situ keratomileusis (LASIK) with spherical myopia, it has deficiencies in astigmatism correction.

Small incision lenticule extraction (SMILE) techniques: patient selection and perspectives.

Cornea, Cataract and Refractive Surgery Services, Dr Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India,

Refractive lenticule extraction is becoming the procedure of choice for the management of myopia and myopic astigmatism owing to its precision, biomechanical stability, and better ocular surface. It has similar safety, efficacy, and predictability as femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and is associated with better patient satisfaction. The conventional technique of small incision lenticule extraction (SMILE) involves docking, femtosecond laser application, lenticule dissection from the surrounding stroma, and extraction. Read More

Small Incision Lenticule Extraction SMILE - The Future of Refractive Surgery is Here.

Mo Med 2018 Jan-Feb;115(1):82-84

J. Quinten Tuckfield, BS, medical student at Kansas City University of Medicine and Biosciences.

Small Incision Lenticule Extraction (SMILE) is a relatively new one-step refractive procedure that has recently been approved by the FDA for the treatment of myopia. It is anticipated myopic astigmatism will be FDA-approved in 2019. The SMILE procedure is shown to have similar efficacy, safety, predictability, and stability as current surgical options, such as LASIK, but has been gaining popularity due to fewer potential complications, such as dry eye incidence and greater biomechanical stability, and faster recovery time.

Comparison of corneal biomechanical changes after refractive surgery by noncontact tonometry: small-incision lenticule extraction versus flap-based refractive surgery - a systematic review.

Acta Ophthalmol 2019 Mar 10;97(2):127-136. Epub 2018 Sep 10.

Department of Ophthalmology, Odense University Hospital, Odense, Denmark.

Corneal refractive surgery disrupts corneal integrity and reduces biomechanical stability in consequence of the beneficial refractive alteration. The minimal invasive cap-based refractive procedure, small-incision lenticule extraction (SMILE), has been proposed to affect corneal integrity less than flap-based procedures, due to the fibre-sparing incision of the strong anterior corneal lamellae. Flap-based procedures include laser-assisted in situ keratomileusis (LASIK), femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and femtosecond lenticule extraction (FLEx). Read More

Review of Corneal Biomechanical Properties Following LASIK and SMILE for Myopia and Myopic Astigmatism.

Open Ophthalmol J 2018 27;12:164-174. Epub 2018 Jul 27.

Department of Ophthalmology, Aarhus University Hospital, Aarhus, Denmark.

Worldwide, femtosecond Laser Assisted Keratomileusis (LASIK) is a well known and commonly used refractive technique, although Small Incision Lenticule Extraction (SMILE) has become increasingly popular since it was introduced in 2011. In LASIK, a corneal flap is cut with a microkeratome or femtosecond laser, followed by thinning of the stromal bed with excimer laser ablation. In SMILE, a minor intrastromal lenticule is cut with a femtosecond laser and subsequently removed through a small incision, leaving the anterior and strongest part of the cornea almost intact.

Comparison Between Q-Adjusted LASIK and Small-Incision Lenticule Extraction for Correction of Myopia and Myopic Astigmatism.

Eye Contact Lens 2018 Nov;44 Suppl 2:S426-S432

Department of Ophthalmology (E.E.-M., M.A., M.S., M.H.), Cairo University, Giza, Egypt; and Department of Optics, Pharmacology and Anatomy (D.P.), University of Alicante, Alicante, Spain.

Purpose: To compare Q-adjusted femtosecond-assisted laser in situ keratomileusis (FS-LASIK) and small-incision lenticule extraction (SMILE) in terms of safety, efficacy, and predictability, as well as in terms of changes in dry eye parameters, corneal biomechanics, higher-order aberrations (HOAs), and corneal asphericity.

Methods: A total of 60 eyes were enrolled in this prospective comparative study: 30 underwent SMILE and 30 underwent FS-LASIK. Changes in manifest refraction, uncorrected distance visual acuity and corrected distance visual acuity, corneal topography, corneal hysteresis (CH), and corneal resistance factor (CRF) (Ocular Response Analyzer, ORA), and dry eye parameters were evaluated during a 3-month follow-up.

Retinal nerve fiber layer thickness after laser-assisted subepithelial keratomileusis and femtosecond LASIK: a prospective observational cohort study.

Clin Ophthalmol 2018 4;12:1213-1218. Epub 2018 Jul 4.

Clínica Novovisión, Madrid, Spain,

Purpose: Based on the assumption that high levels of intraocular pressure (IOP) during femtosecond laser-assisted in situ keratomileusis (FS-LASIK) may compromise the retinal nerve fiber layer (RNFL), newer femtosecond platforms that operate without causing significant IOP elevation have been developed in recent years. However, this assumption has not been adequately tested. The aim of the current study was to evaluate possible changes in RFNL thickness in nonglaucomatous myopic patients undergoing FS-LASIK using the 60 KHz IntraLase device that significantly elevates the IOP for an appreciable period of time vs an advanced surface ablation technique (laser-assisted subepithelial keratomileusis, LASEK) that does not induce any IOP elevation.

Initial Single-Site Surgical Experience with SMILE: A Comparison of Results to FDA SMILE, and the Earliest and Latest Generation of LASIK.

Ophthalmol Ther 2018 Dec 29;7(2):347-360. Epub 2018 Jun 29.

HDR Research Center, Hoopes Vision, Draper, UT, USA.

Introduction: The primary objective was to show our initial surgical single-site experience with small incision lenticule extraction (SMILE) after the official enrollment in March 2017 following Food and Drug Administration (FDA) approval for simple myopia in late 2016 in the United States and, subsequently, compare our results to the earliest and most advanced generation of excimer platforms for laser-assisted in situ keratomileusis (LASIK) surgery.

Methods: This was a retrospective single-site study of 68 eyes from 35 patients who had SMILE surgery. The patients' preoperative and postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest sphere, manifest cylinder, intraoperative complications, and preoperative and postoperative visual symptoms were collected.
