PURPOSE OF REVIEW: As a flapless procedure, SMILE brings benefits to refractive surgery, such as lower corneal biomechanical impact, less dry eye risk and less stromal bed exposure. However, the longer learning curve can be a risk factor for complications. This article aims to discuss SMILE complications and proposes a categorized analysis of occurrences, dividing into two groups: intraoperative and postoperative complications. Among intraoperative, we also suggest a subdivision between those related to the laser (lenticule construction), tissue separation (lenticule dissection) and tissue removal (lenticule extraction)...

Purpose: To report the case of a patient with Crystalens, an accommodating posterior-chamber intraocular lens (IOL), who experienced a myopic shift following subsequent vitrectomy with gas tamponade. We propose a hypothesis as to why this myopic shift occurred and analyze its validity based on current literature. Observations: A patient had cataract surgery with implantation of a Crystalens AT-50AO +21D. Preoperative A-scan measured anterior chamber depth (ACD) to be 3...

Purpose: To report the findings and surgical techniques on two cases of severe tilting of an intraocular lens (IOL) that had been implanted with intrascleral fixation and the tilting was detected by anterior segment optical coherence tomography (AS-OCT). Observations: Two patients underwent flanged intrascleral fixation of an IOL with the double needle technique. AS-OCT showed that the tilt of IOL was 25.3° in Case 1 and was 38.1° in Case 2, and a second surgery was planned to reduce the IOL tilt...

REVIEW
Jagger C Koerner, Mary J George, Dale R Meyer, Michael G Rosco, Matthew M Habib
Iodine has been recognized as an effective bactericide since the 1800's, and povidone-iodine (PI) solution has been applied to the ocular surface and periocular skin since the 1980's to prevent endophthalmitis in cataract surgery. In vitro, PI solution kills bacteria very quickly at dilute concentrations (0.05-1.0%). In many instances, PI kills bacteria more quickly at these dilute concentrations than more conventional (5%-10%) concentrations. This is due to greater availability of diatomic free iodine in dilute solution, the bactericidal component of PI...

Purpose: To evaluate the efficacy and safety of plasma rich in growth factors (PRGF) eye drops in patients with glaucoma with secondary ocular surface disorders (OSDs) due to surgeries and topical hypotensive drugs use. Materials and methods: A retrospective case-series study design was used including six patients (eight eyes) diagnosed with glaucoma who received surgical (nonpenetrating deep sclerectomy and/or trabeculectomy) and medical treatments (hypotensive eye drops) to control intraocular pressure (IOP) and who developed secondary OSDs, unresponsive to conventional treatments...

PURPOSE: To evaluate and compare early postoperative pain after photorefractive keratectomy (PRK) and corneal crosslinking (CXL). SETTING: Khatam-al-Anbia Eye Hospital, Mashhad, Iran. DESIGN: Prospective case series. METHODS: The PRK group included patients with simple refractive errors whereas the CXL group included patients with clinical keratoconus. The groups were compared regarding the level of pain based on the visual analogue scale (VAS), verbal rating scale (VRS), and Wong-Baker FACES pain rating scale immediately after surgery, 6 hours postoperatively, and 1, 3, and 7 days postoperatively...

J Wang, Y X Cao
The aim of modern micro-incision phacoemulsification combined with foldable intraocular lens implantation and femtosecond laser-assisted cataract surgery is evolving from a simple pursuit of recuperation to a refractive procedure, which involves the correction of ametropia according to preoperative and postoperative refractive conditions, especially corneal astigmatism, in order to achieve the goal of optimized postoperative uncorrected full range of vision. Nowadays, due attention to the effect of preoperative corneal astigmatism, surgery-induced astigmatism and residual astigmatism after operation is lacked, which affect postoperative visual acuity significantly...

PURPOSE: Procedures to treat medically refractory trigeminal neuralgia (MRTN) include stereotactic radiosurgery (SRS) and microvascular decompression (MVD). The aim of this study was to compare outcomes of SRS versus MVD in the treatment of MRTN, with a subgroup focus on those being treated for the first time. METHODS: Search strategy was performed using the PRISMA guidelines for article identification, screening, eligibility and inclusion. Relevant articles were identified from six electronic databases from their inception to June 2017...

The aim of this study was to evaluate the influence of the preoperative wearing time on the postoperative effect in children with partially accommodative esotropia.Sixty children with partially accommodative esotropia who visited our hospital were placed in full cycloplegic refraction by using 1% Atropine eye gel and then wore full hyperopic correction glasses. Children were divided into groups A and B according to the preoperative wearing time. The visual acuity, eye position, and results of the synoptophore and Titmus stereoacuity tests were recorded before and half a year after the surgery in each group, and appropriate statistical analyses were conducted...

PURPOSE: To describe a case in which post-LASIK corneal ectasia was treated using an allogeneic lenticule implanted into the recipient eye. METHODS: A 29-year-old man presented with bilateral ectasia 10 years after LASIK. Manifest refraction was -1.50 -3.25 × 15° in the right eye and -13.50 -6.00 × 10° in the left eye. Because of contact lens intolerance in the left eye, the authors decided to implant an allogenic corneal lenticule, created by small incision lenticule extraction with the VisuMax laser (Carl Zeiss Meditec, Jena, Germany) in a donor eye with a refraction of +5...

PURPOSE: To investigate two approaches for femtosecond laser-assisted cataract surgery (FLACS) in patients with phakic intraocular lenses (IOLs). METHODS: Anterior capsulotomy and lens fragmentation were performed with an image-guided femtosecond laser. Laser treatment was performed under sterile conditions prior to (technique 1, 5 cases) or after (technique 2, 5 cases) phakic IOL explantation. RESULTS: In technique 1, gas accumulated between the phakic IOL and the anterior capsule...

PURPOSE: To compare the surgically induced astigmatism (SIA) vector, flattening effect, torque, and wound architecture following femtosecond laser and manual clear corneal incisions (CCIs). METHODS: In a double-armed, randomized, prospective case series, cataract surgery was performed for 600 eyes using femtosecond laser (300 eyes) or manual (300 eyes) 2.4-mm CCIs in temporal or superior oblique locations. SIA, flattening effect, torque, and the summated vector mean for SIA were calculated...

PURPOSE: To determine the risk factors for re-treatment following LASIK in hyperopic eyes. METHODS: In this retrospective study, consecutive hyperopic eyes underwent LASIK at the Care Vision Laser Centers, Tel-Aviv, Israel, between January 2000 and October 2014. Patients were divided into two groups according to whether or not they underwent additional refractive surgery (re-treatment). Logistic regression was performed to determine predictors of re-treatment. RESULTS: Overall, 1,776 eyes of 888 patients were included, of which 82 (4...

AIMS: To describe the long-term outcomes of deep anterior lamellar keratoplasty (DALK) performed after Descemet stripping automated endothelial keratoplasty (DSAEK) in cases of infection and residual stromal opacity. METHODS: Ten eyes of nine consecutive patients undergoing DALK after DSAEK at a single tertiary referral center (SNEC) from 2011 to 2016 were analyzed for best spectacle-corrected visual acuity (BSCVA), refraction, spherical equivalent (SE) and cylinder, as well as graft diameters, survival, and complications...

Background: To investigate the impact of the orientation of preoperative corneal astigmatism on achieving the postoperative target refraction following monofocal intraocular lens (IOL) implantation. Methods: This study enrolled 339 eyes who had uneventful cataract surgery or refractive lens exchange (RLE) with subsequent monofocal IOL implantation. Eyes were initially categorized dependent upon axial length and then on the orientation of preoperative anterior corneal astigmatism...
