Purpose We describe a scleral suture fixation technique for dislocated plate haptic toric intraocular lens (IOL) implantation. Materials and methods A double-armed 10-0 straight polypropylene suture was passed into the eye from the sclera (2 mm away from the limbus). A suture needle was passed through the hole on the corner of the IOL and pulled out from the paracentesis with a 27-gauge needle. Afterward, the suture needle was reinserted from the same paracentesis and then removed from the eye with the help of a 27-gauge needle entering the eye from a nearby point to the first scleral entrance...

Giacomo Torlai, Roger G Melko
We present an algorithm for error correction in topological codes that exploits modern machine learning techniques. Our decoder is constructed from a stochastic neural network called a Boltzmann machine, of the type extensively used in deep learning. We provide a general prescription for the training of the network and a decoding strategy that is applicable to a wide variety of stabilizer codes with very little specialization. We demonstrate the neural decoder numerically on the well-known two-dimensional toric code with phase-flip errors...

BACKGROUND: To compare the clinical outcomes after implantation of AcrySof Toric IOLs with different clear corneal incisions. METHODS: Sixty cataract patients with regular corneal astigmatism who underwent phacoemulsification combined with implantation of an AcrySof Toric IOL were enrolled. They were divided into two groups according to the position of the clear corneal incision: steep-axis and non-steep-axis. Main outcome measurements included visual acuity, residual astigmatism and changes of corneal astigmatism 3 months postoperatively...

PURPOSE: To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction. MATERIALS AND METHODS: The study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of the three procedures - T-ICL, femto-LASIK, or ReLEx SMILE - for correction of myopic astigmatism within the range of -3 to -8 D spherical equivalent (SE), with a minimum astigmatism of -0...

OBJECTIVES: To determine repeatability of measurements using the sMap3D Corneo-Scleral Topographer in patients presenting for scleral lens fitting. METHODS: As part of our standard clinical evaluation, 25 eyes of 23 patients who presented for scleral lens fitting were examined twice in the same day with the sMap3D in this retrospective study. Sagittal height (SAG), sMap3D principal toricity magnitude (as calculated by the instrument software), and steep axis location were measured at a 16-mm chord diameter...

PURPOSE: To compare crystalline lens tilt in eyes before and intraocular lens (IOL) tilt in eyes after cataract surgery using swept-source optical coherence tomography (SS-OCT) (IOLMaster 700). SETTING: Hanusch Hospital, Vienna, Austria. DESIGN: Prospective case series. METHODS: Patients' eyes were scanned 1 week before and 2 months after cataract surgery with IOL implantation using an SS-OCT device. This device performs B-scans along 6 meridians (0, 30, 60, 90, 120, and 150 degrees) to determine lens and IOL tilt...

PURPOSE: To analyse the visual quality achieved by fitting corneo-scleral contact lenses (CScL) in an uncommon case of bilateral keratoconus, high hyperopia and astigmatism. METHODS: A 45-year-old man presented for eye examination due to the unsatisfactory quality of his vision wearing soft toric contact lenses. He presented high hyperopia and astigmatism with bilateral keratoconus. He was fitted with CScL to correct his irregular astigmatism and ocular aberrations...

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...
