Fritz H Hengerer, Ina Conrad-Hengerer
Implantation of artificial intraocular lenses (IOL) after cataract removal today represents the standard of care in the field of anterior segment surgery. In refractive lens exchange cases the natural lens is replaced by an IOL to correct different types of refractive situations. In the majority of the operations the refractive result is satisfying with only few deviations from target refraction.But daily practice reveals some outliers from the intended corrections with the need for further refractive enhancements, respectively...

PURPOSE: To evaluate the outcomes of myopic small incision lenticule extraction (SMILE) monovision in presbyopic patients. METHODS: This study included 49 presbyopic patients older than 45 years seeking surgical correction of myopia or myopic astigmatism who underwent bilateral SMILE with planned monovision in the SMILE Eyes Clinic Linz, Austria. Target refraction was plano for dominant (distance) eyes and ranged between -1.25 and -0.50 D for nondominant (near) eyes...

PURPOSE: A single-center, cross-sectional study was designed to assess and compare objective and subjective quality of vision of patients intervened with penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK) and Descemet membrane endothelial keratoplasty (DMEK). METHODS: Forty-six patients previously intervened with PK (22 eyes), DALK (7 eyes) and DMEK (17 eyes) were recruited. Visual evaluation included spherical and cylindrical refraction, distance corrected visual acuity (DCVA), photopic contrast sensitivity (CS), optical quality, measured with the HD Analyzer (objective scattering index [OSI], MTF cut-off and Strehl ratio), and ocular and corneal aberrometry, measured with the KR-1W Wavefront Analyzer...

Background: To assess the clinical consequences of AcrySof toric intraocular lens (IOL) and Hoya toric IOL implantation to correct preexisting corneal astigmatism in patients undergoing cataract surgery. Materials and Methods: In this study, we examined 55 eyes of 45 patients with at least 1.00 D corneal astigmatism who were scheduled for cataract surgery. After phacoemulsification, toric IOL was inserted and axis was aligned. We observed the patients, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry, manifest refraction, and IOL axis alignment 6 months after surgery...

PURPOSE: Minimal loss of corneal endothelial cells during corneal transplantation is a major target but remains a point of controversy among specialists. Hence, the available method to best achieve this continues to stir progress in the field. The aim of this study is to evaluate the use of the Endosaver injector device for graft insertion in Descemet's stripping endothelial keratoplasty (DSEK) and compare the visual outcomes and endothelial cell survival between the Endosaver injector and Goosey grasping forceps insertion techniques...

PURPOSE: To characterize current practice preferences of pediatric ophthalmologists in the management of amblyopia and whether these are influenced by demographic variables. METHODS: A 10-question survey was distributed to all pediatric ophthalmologists and fellows attending the Annual Joseph H. Calhoun Pediatric Ophthalmology Forum at Wills Eye Hospital in 2016. The questionnaire consisted of demographic information and clinical management of amblyopia using clinical scenarios commonly encountered in pediatric ophthalmology practice...

PURPOSE: To investigate the development pattern and related factors of postoperative re-drift in infantile esotropia. METHODS: A total of 112 patients with infantile esotropia who underwent surgery before 3 years of age were included. Surgical outcomes were divided into (1) consecutive exotropia: more than 8 prism diopters (PD) of exodeviation; (2) recurrent esotropia: more than 8 PD of esodeviation; and (3) monofixation syndrome: maintenance of deviations within 8 PD...

PURPOSE: Advances in surgical techniques allow implantation of intraocular lenses (IOL) with cataract extraction, even in young children. However, there are several challenges unique to the pediatric population that result in greater degrees of postoperative refractive error compared to adults. METHODS: Literature review of the techniques and outcomes of pediatric cataract surgery with IOL implantation. RESULTS: Pediatric cataract surgery is associated with several sources of postoperative refractive error...

BACKGROUND: We described a modified 'hydroexpression' technique for the lenticule removal during small-incision lenticule extraction (SMILE) surgery and compared the results with conventional forceps method. METHODS: This was a retrospective, comparative study of 50 patients who underwent SMILE surgery by the same surgeon. We compared the 1-week and 3-months postoperative results after SMILE using the hydroexpression technique with the conventional forceps technique...

PURPOSE: To compare the sealability of femtosecond laser-constructed and manual clear corneal incisions (CCIs) in patients undergoing cataract surgery. METHODS: This prospective, randomized study included 62 eyes of 62 patients with cataract grade 1 to 2 (LOCS scale). The patients were randomly assigned (1:1) for creation of either manual CCI (with a 2.4-mm keratome) or femtosecond laser-assisted CCI (LENSAR, Inc., Orlando, FL) (31 eyes in each group) before undergoing femtosecond laser-assisted cataract surgery...

PURPOSE: Dry eye is known to impact on clinical outcomes after laser vision correction and the use of a newer 'all femtosecond laser' surgical approach may be associated with less impact on the ocular surface post-operatively. The purpose of this study was to evaluate the early clinical outcomes and tear instability after the first small incision lenticule extraction (SMILE) cases undertaken by three surgeons at a single site in the UK. METHODS: Retrospective audit...
