PURPOSE: To compare the 2-years visual and refractive outcomes between small-incision lenticule extraction (SMILE) and wavefront-guided laser in situ keratomileusis (LASIK) in eyes with myopia and myopic astigmatism. METHODS: Our retrospective case-control study examined 30 eyes of 30 patients with the manifest refraction spherical equivalent (MRSE) of -3.71 ± 1.83 dioptres (D) who underwent SMILE and 30 eyes of 30 patients with MRSE of -3.81 ± 1.40 D who underwent wavefront-guided LASIK...

OBJECTIVES: To investigate the shifting of the line of sight (LoS) and the refractive, topographic, and aberrometric parameters that may be associated with the shifting of the LoS in eyes with tilted disk syndrome (TDS). METHODS: Eighty left eyes of 80 subjects with TDS (Study Group) and 70 left eyes of 70 subjects with myopia and astigmatism (Control Group) were included in this study. Line-of-sight coordinates on the horizontal (x) and vertical (y) axes, refractive, topographic, and aberrometric parameters were evaluated...

PURPOSE: To evaluate the effect of non-keratometric ocular astigmatisms on visual and refractive outcomes after photorefractive keratectomy (PRK) for correction of myopic astigmatisms. METHODS: Seventy one eyes of 36 subjects were enrolled in this study. Patients underwent PRK for treatment of myopia. Subjects were evaluated for refractive error, keratometry, and visual acuity before and six months after surgery. Pre- and post-op non-keratometric astigmatisms were calculated by vectorial analysis of the difference between the corneal plane refractive astigmatism and keratometric astigmatism...

PURPOSE: The aim was to assess the repeatability of Fourier transfom analysis of videokeratographic data using Pentacam in normal (CG), keratoconic (KC) and post-CXL (CXL) corneas. METHODS: This was a prospective, clinic-based, observational study. One randomly selected eye from all study participants was included in the analysis: 62 normal eyes (CG group), 33 keratoconus eyes (KC group), while 34 eyes, which had already received CXL treatment, formed the CXL group...

A 68-year-old woman presented with infectious crystalline keratopathy 4 months after she underwent a combined phacoemulsification and Descemet's stripping endothelial keratoplasty for Fuch's endothelial dystrophy in her left eye. After 5 months of topical moxifloxacin 1%, the infiltrate responded well but had not completely resolved, with the resulting endothelial failure requiring a penetrating keratoplasty 9 months after the initial operation. Microbiology identified Enterococcus faecalis with the histopathology demonstrating bacterial colonies within the graft interface...

The aim of this study was to determine whether dynamic accommodation responds to isolated blur cues without feedback, and without changes in the distance of the object. Nine healthy subjects aged 21 to 40 years were recruited. Four different aberration patterns were used as stimuli to induce blur: (1) the eye's natural, uncorrected, optical aberrations, (2) all aberrations corrected, (3) spherical aberration only, and (4) astigmatism only. The stimulus was a video animation based on computer-generated images of a monochromatic Maltese cross...

PURPOSE: To investigate the detailed distribution of corneal epithelial thickness in single sectors and its correlated characteristics in myopic eyes. METHODS: SD-OCT was used to measure the corneal epithelial thickness distribution profile. Differences of corneal epithelial thickness between different parameters and some correlations of characteristics were calculated. RESULTS: The thickest and thinnest part of epithelium were found at the nasal-inferior sector (P < 0...

PURPOSE: To examine how corneal astigmatism changes with age over 20 years after cataract surgery and to assess whether the changes differ from those in eyes that did not have surgery. SETTING: Hayashi Eye Hospital, Fukuoka, Japan. DESIGN: Retrospective case study. METHODS: Using an autokeratometer, corneal astigmatism was measured preoperatively, at baseline (the day the surgically induced astigmatism stabilized), and 10 years and 20 years after baseline...

OBJECTIVE: To determine whether the visual outcomes of the refractive surgery technique small incision lenticule extraction (SMILE), are stable, effective, and predictable for high myopia over a four-year period. RESEARCH DESIGN: This is a retrospective study. The data were collected between March 2012 and July 2016. PARTICIPANTS: Two hundred and forty-eight patients participated in the study; that is, 496 eyes: 140 eyes of 70 patients (52 women/18 men) were classified into the highly myopic group (refraction measured in spherical equivalent (RMSE)>-6 D), and 356 eyes of 178 patients (98 women/80 men) into the control group (RMSE<-6 D)...

REVIEW
T Kohnen, G Steinwender
OBJECTIVE AND PRINCIPLES: In LASIK, after cutting a lamellating stromal corneal incision (flap) with a microkeratome or a femtosecond laser, the underlying tissue is treated with an excimer laser for refractive correction. The objective is to achieve independency from spectacles and contact lenses due to correction of ametropia. INDICATIONS: Surgery is indicated when the patient wishes to achieve independency from spectacles and contact lenses. For LASIK, the German Commission for Refractive Surgery defined a range of applicability for myopic correction up to -8 diopters (D), astigmatic correction up to 5 D and hyperopic correction up to +3 D...

A prospective comparative study assessing the importance of the intra-operative dynamic rotational tracking-especially in the treatment of astigmatisms in corneal refractive Excimer laser correction-concerning clinical outcomes is presented. The cyclotorsion from upright to supine position was measured using iris image comparison. The Group 1 of patients was additionally treated with cyclorotational control and Group 2 only with X-Y control. Significant differences were observed between the groups regarding the mean postoperative cylinder refraction (p < 0...

PURPOSE: This study aimed to evaluate the long-term stability of minimally invasive radial keratotomy (mini-RK) for eyes with mild to moderate keratoconus. DESIGN: Retrospective observational case series. METHODS: Eleven eyes from 6 patients with hard contact lens (HCL)-intolerant keratoconus underwent mini-RK and were followed up for more than 5 years. The mini-RK consisted of 8 radial incisions with depths of 90% of the thinnest corneal thickness, based on the Lindstrom nomogram...

BACKGROUND: Intrascleral fixation of an intraocular lens (IOL) is used in eyes that lack capsular support. The aim of the study is to determine whether a larger optical diameter IOL will decrease the higher-order aberrations (HOAs) when the haptics are extended for intrascleral fixation than a smaller diameter IOL. METHODS: Three-piece acrylic IOLs with 6.0 mm optics (X-60, VA-60BBR) and 7.0 mm optics (X-70, VA-70 AD) were fixed at lengths of 13, 14, 15, 16, or 17 mm...

PURPOSE: To describe the technique of limbal stem cell-sparing corneoscleroplasty for the management of advanced keratoglobus. METHODS: A patient with bilateral advanced keratoglobus, with best-corrected visual acuity of 20/400 in the right eye and 20/200 in the left eye, underwent limbal stem cell-sparing corneoscleroplasty of the right eye. Initially, a 360-degree limbal incision with 200-μm depth was created, followed by a sublimbal tunnel dissection into the sclera, in order to conserve stem cells...
