Fritz H Hengerer, Ina Conrad-Hengerer
In refractive surgery the removal of the natural lens followed by implantation of an artificial intraocular lens has been an established method to treat refractive errors. The term "clear lens exchange" separates this approach from cataract surgery, where a cloudy lens has to be removed. With regard to currently available intraocular lens technologies, there is a wide range to correct myopia, hyperopia as well as astigmatism. Trifocal or extended depth-of-focus lenses (EDOF) even with a toric component offer the patients a potential benefit to further address presbyopia, respectively...

PURPOSE: To report the outcomes of lensectomy in spherophakic eyes with subluxated or dislocated crystalline lenses and secondary glaucoma. METHODS: Lensectomy was performed in 52 eyes, 36 eyes with lens subluxation and 16 eyes with lens dislocation with secondary glaucoma from 1991 to 2016. Glaucoma was diagnosed based on intraocular pressure (IOP) ≥22 mm Hg and/or glaucomatous optic disc damage. Complete success was defined as IOP ≥5 and ≤21 mm Hg without antiglaucoma medications (AGMs) or surgery, and eyes needing oral AGM or surgical intervention for IOP control or those with complication causing loss of light perception were considered failure...

Measuring the eye's mechanical properties in vivo and with minimally invasive techniques can be the key for individualized solutions to a number of eye pathologies. The development of such techniques largely relies on a computational modelling of the eyeball and, it optimally requires the synergic interplay between experimentation and numerical simulation. In Astrophysics and Geophysics the remote measurement of structural properties of the systems of their realm is performed on the basis of (helio-)seismic techniques...

We describe the use of a simple tool to evaluate the postoperative alignment of toric intraocular lenses (IOLs). The entire anterior segment is scanned using anterior segment optical coherence tomography and analyzed with an internal dedicated tool. A topographic map is displayed along with an anterior segment image, including a linear axis marker centered on the corneal apex. The marker can be rotated until it is aligned with the line connecting the IOL marking dots, precisely reproducing the IOL astigmatic axis, which is measured in angle degrees...

PURPOSE OF REVIEW: To describe recent evidence regarding methods of evaluation of retinal structure and function prior to cataract surgery. RECENT FINDINGS: Studies in patients with cataract but no clinically detectable retinal disease have shown that routine use of optical coherence tomography (OCT) prior to cataract surgery can detect subtle macular disease, which may alter the course of treatment or lead to modification of consent. The routine use of OCT has been especially useful in patients being considered for advanced-technology intraocular lenses (IOLs) as subtle macular disease can be a contraindication to the use of these lenses...

PURPOSE: To compare the effect of spherical aberration on optical quality in eyes with two different aspherical intraocular lenses. METHODS: 120 eyes of 60 patients underwent phacoemulsification. In patients' eyes, an aberration-free IOL (Aspira-aA; Human Optics) or an aberration-correcting aspherical IOL (Tecnis ZCB00; Abott Medical Optics) was randomly implanted. After surgery, contrast sensitivity and wavefront measurements as well as tilt and decentration measurements were performed...

INTRODUCTION: Understanding the evolution of complications after scleral-fixated lens placement demonstrates advantageous surgical techniques and suitable candidates. MATERIALS/METHODS: A literature search in PubMed for several terms, including "scleral intraocular lens complication," yielded 17 relevant articles. RESULTS: Reviewing complication trends over time, lens tilt and suture erosion have decreased, cystoid macular edema has increased, and retinal detachment has remained the same after scleral-fixated lens placement...

PURPOSE: To review the history of cataract surgery over the past 100 years, and to offer predictions about new developments that may occur during the next 50 years. DESIGN: Interpretive essay. METHODS: Review of historical literature and author experiences pertaining to cataract surgery, with commentary and perspective. RESULTS: By this time, cataract surgery has advanced to the point that Kelman's introduction of phacoemulsification and use of intraocular lenses (IOLs), both very controversial when initially introduced, have become state of the art...

PURPOSE: To investigate the tilt and decentration of the crystalline lens and the intraocular lens (IOL) relative to the corneal topographic axis using anterior segment ocular coherence tomography (AS-OCT). METHODS: A sample set of 100 eyes from 49 subjects (41 eyes with crystalline lenses and 59 eyes with IOLs) were imaged using second generation AS-OCT (CASIA2, TOMEY) in June and July 2016 at Okayama University. Both mydriatic and non-mydriatic images were obtained, and the tilt and decentration of the crystalline lens and the IOL were quantified...

The performance of an intraocular lens is determined by several factors such as the surgical technique, surgical complications, intraocular lens biomaterial and design, and host reaction to the lens. The factor indicating the biocompatibility of an intraocular lens is the behavior of inflammatory and lens epithelial cells. Hence, the biocompatibility of intraocular lens materials is assessed in terms of uveal biocompatibility, based on the inflammatory foreign-body reaction of the eye against the implant, and in terms of capsular biocompatibility, determined by the relationship of the intraocular lens with residual lens epithelial cells within the capsular bag...

Endophthalmitis, an inflammation of the eye due to perioperative infection, may occur after cataract surgery. Intraocular lenses (IOLs) loaded with an antibiotic have been proposed as an alternative to the conventional postoperative endophthalmitis prophylaxis, since the antibiotic is delivered directly to the target site. In this work, an IOL-based antibiotic releasing system was prepared from a copolymer used in the production of IOLs and a fluoroquinolone used in endophthalmitis prophylaxis (moxifloxacin, MFX)...

PURPOSE: To evaluate whether retropupillary fixation of the iris-claw intraocular lens (IOL) is a safe and effective treatment option in children with large lens subluxations. METHODS: Fourteen eyes of children between the ages of 8-17 years with lens subluxations more than 7 clock hours underwent pars plana lensectomy-vitrectomy with implantation of the iris-claw IOL in the retropupillary position as a primary procedure. The best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal endothelial count (EC) and the lens position using ultrasound biomicroscopy (UBM) were assessed pre- and postoperatively...
