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...

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...

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.

Purpose: Evaluation of spherical component (SC), regular astigmatism (RA), and irregular astigmatism (IA, ie, Asymmetry and Irregularities) 3 years after small incision lenticule extraction (SMILE) and comparison to femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). Methods: Thirty-two eyes of 21 patients who underwent SMILE for myopia and astigmatism were compared with 32 eyes of 21 patients treated with FS-LASIK. Scheimpflug images were obtained preoperatively and 3 years postoperatively. Fourier analysis of keratometric-derived parameters (SC, RA, Asymmetry, and Irregularities) of the anterior, pos...

Conclusions: Our findings suggest that femto-LASIK on eyes with prior FLEK is safe and effective in improving visual acuity and reducing residual astigmatism. PMID: 31559093 [PubMed]

Authors: Breyer DRH, Beckers L, Hagen P, Kaymak H, Klabe K, Auffarth GU, Kretz FTA Abstract AIM: Our aim was to retrospectively compare ReLEx Smile to femtosecondlaser-assisted LASIK (FsLASIK, femto-LASIK) in terms of safety, efficacy, stability as well as intraoperative complications. Comparable studies only show the results over the course of 3 years, making our data the first to examine longer term results. MATERIALS/METHODS: To accomplish this, we compared 404 eyes after FsLASIK (Mel 80, Carl Zeiss Meditec) and 1192 eyes after ReLEx SMILE (VisuMax, Carl Zeiss Meditec). We collected patients' data at 6 month...

derli A Abstract PURPOSE: To evaluate the postoperative high-order aberration differences of femto-LASIK surgery in 6.5 and 7 mm optic zones. PATIENTS AND METHODS: We retrospectively reviewed 80 eyes of 40 patients with myopia or myopia with astigmatism who underwent femtosecond LASIK surgery. Q values, z3, 3 (h. trefoil), z3, -3 (v. trefoil), z3, 1 (h. coma), z3, -1 (vertical coma), z4, 0 (spherical aberration), z5, -1 (second other v. coma), aberration coefficients were evaluated 3 months after surgery. Central corneal thicknesses, intraocular pressures, patient ages and genders, optical zone ...
