PURPOSE: To evaluate the impact of the lens aberrations on the adaptive optics visual simulation of pseudophakic intraocular lens (IOL) profiles. METHODS: In 20 right phakic eyes, lens higher order aberrations (HOAs) were calculated as the whole eye minus the corneal aberrations. Visual simulation using low and high contrast corrected distance visual acuity (CDVA) testing was carried out with the VAO instrument (Voptica, SL, Murcia, Spain), considering three optical conditions of the lens: removing HOA (no lens-HOA), removing spherical aberration (no lens-SA), and with lens HOA (natural condition)...

PURPOSE: To report the outcomes of a series of 16 patients who had secondary surface ablation within 4 weeks of an aborted femtosecond laser-assisted in situ keratomileusis (FS-LASIK) procedure. METHODS: A retrospective chart review of electronic medical record data from 2011 to 2015 was performed to identify eyes of patients who had an aborted FS-LASIK procedure followed by secondary surface ablation (photorefractive keratectomy or laser epithelial keratomileusis) within 4 weeks of the primary procedure...

PURPOSE: To investigate the results after photorefractive keratectomy (PRK) followed immediately by standard 30-minute corneal cross-linking (CXL) for keratoconus. METHODS: This retrospective study included 26 eyes of 16 patients with keratoconus. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction spherical equivalent (SE) and cylinder, apical keratometry, corneal higher order aberrations (HOAs), and corneal haze were evaluated...

PURPOSE: To evaluate differences in higher order aberrations (HOAs) between femtosecond laser-assisted cataract surgery (FLACS) and manual cataract surgery. METHODS: In this retrospective cohort study, consecutive patients undergoing FLACS or manual cataract surgery with implantation of an intraocular lens from January 2017 to February 2018 were recruited. Patients underwent aberrometry testing at least 2 months postoperatively. The primary endpoint was internal coma < 0...

PURPOSE: To investigate the characteristics and changes in microdistortions in Bowman's layer 3 years after small incision lenticule extraction (SMILE). METHODS: In this non-randomized, prospective study, 50 eyes of 28 patients who received SMILE with a mean spherical equivalent of -6.72 ± 1.41 diopters (D) were divided into a thin lenticule group (lenticule thickness ⩽ 135 µm) and a thick lenticule group (lenticule thickness > 135 µm). Examinations were performed preoperatively and 1 day, 1 month, and 3 years after SMILE...

PURPOSE: To observe the epithelial remodeling over a 9-mm diameter cornea induced by topography-guided femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia correction using spectral-domain optical coherence tomography (SD-OCT). METHODS: Forty-three eyes of 22 patients who underwent topography-guided FS-LASIK for myopic correction were included. The "Pachymetrywide" scan pattern was used to generate the epithelial thickness map using SD-OCT preoperatively and 1, 3, and 6 months postoperatively...

PURPOSE: To evaluate the outcomes of primary topography-guided laser in situ keratomileusis (LASIK) in eyes with subjective refractive astigmatism of 2.00 diopters (D) or greater. METHODS: This was a prospective study in consecutive eyes with cylinder of 2.00 D or greater that had LASIK using the Alcon WaveLight EX500 excimer laser and T-CAT/Contoura software (Alcon Laboratories, Inc., Fort Worth, TX). The accuracy, efficacy, safety, cylinder vector analysis, higher order aberrations, and patients' subjective quality of vision were assessed...

PURPOSE: To describe the therapeutic use of CIRCLE software (Carl Zeiss Meditec, Jena, Germany) for the management of retained lenticule tissue after complicated small incision lenticule extraction (SMILE). METHODS: Two patients were referred for consultation and treatment due to intraoperative complications during SMILE. In case 1, a black patch during laser delivery caused the lenticule to be torn irregularly from the undersurface during extraction and a sliver of it was retained in the pocket...

PURPOSE: To compare the accuracy of different intraocular lens (IOL) calculation formulas available on the American Society of Cataract and Refractive Surgery (ASCRS) post-refractive surgery IOL power calculator for the prediction of multifocal IOL power after previous corneal refractive laser surgery for myopia. METHODS: An analysis and comparison were performed of the accuracy of three methods using surgically induced change in refraction (ie, Masket, Modified Masket, and Barrett True-K formulas) and three methods using no previous data (ie, Shammas, Haigis-L, and Barrett True-K No History formulas)...

PURPOSE: To determine the rotational stability of the Rayner 600S intraocular lens (IOL) (Rayner, Worthing, United Kingdom) using objective image analysis techniques. METHODS: A total of 66 patients (mean age: 69.92 ± 8.45 years) with healthy eyes presenting for routine cataract surgery were implanted monocularly with the 600S IOL and followed up over 90 to 180 days postoperatively. Images of the IOL were captured through a maximally dilated pupil (tropicamide 1...

PURPOSE: To assess the effectiveness of small incision lenticule extraction (SMILE) as a function of the astigmatism level and type. METHODS: A total of 102 right eyes were included in this study. Refractive astigmatism and corneal astigmatism measured with Scheimpflug technology were retrieved from the preoperative visit and the 3-month follow-up visit. Patients were split into three groups according to the preoperative refractive astigmatism (0.50, 0.75 to 1.25, and 1...

PURPOSE: To evaluate the long-term visual and refractive outcomes, optical quality, and stability of the cornea and axial length after small incision lenticule extraction (SMILE) for the correction of high myopia with a maximum myopic meridian exceeding 10.00 diopters (D). METHODS: Via a prospective cohort study, 53 eyes (53 patients) with a maximum myopic meridian exceeding 10.00 D were corrected with a VisuMax femtosecond laser (version 3.0; Carl Zeiss Meditec AG, Jena, Germany) at the Zhongshan Ophthalmic Center of Sun Yat-sen University...

PURPOSE: To evaluate visual and refractive outcomes of small incision lenticule extraction (SMILE) for hyperopia. METHODS: This prospective study of vertex-centered hyperopic SMILE used the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany). Inclusion criteria were maximum attempted hyperopic meridian of between +1.00 and +7.00 diopters (D) and corrected distance visual acuity (CDVA) of 20/40 or better. Lenticule parameters were 6.3- to 6.7-mm diameter, 2-mm transition zone, 30-µm minimum thickness, and 120-µm cap thickness...

PURPOSE: To investigate whether topography-guided laser in situ keratomileusis (LASIK) with anterior corneal astigmatism measured on the WaveLight Contoura (Alcon Laboratories, Inc., Fort Worth, TX) leads to better refractive outcomes compared to treating on the clinically measured manifest refractive astigmatism axis in eyes with primary myopic astigmatism. METHODS: Retrospective analysis of 1,274 consecutive LASIK eyes treated on the topography-measured anterior corneal astigmatism axis compared to eyes treated on the conventional clinical manifest refractive astigmatism axis...

PURPOSE: To evaluate extracellular matrix regulators and inflammatory factors in a patient who developed ectasia after small incision lenticule extraction (SMILE) despite normal preoperative tomographic and biomechanical evaluation. METHODS: The SMILE lenticules from both eyes of the patient with ectasia and three control patients (5 eyes) matched for age, sex, and duration of follow-up were used for gene expression analysis of lysyl oxidase (LOX), matrix metalloproteinase 9 (MMP9), collagen types I alpha 1 (COLIA1) and IV alpha 1 chain (COLIVA1), transforming growth factor-beta (TGF-beta), bone morphogenetic protein 7 (BMP7), interleukin-6 (IL-6), cathepsin K, cluster of differentiation 68, integrin beta-1, and tissue inhibitor of metalloproteinase-1 (TIMP1)...
