BACKGROUND: An intraocular lens (IOL) is a synthetic lens that is surgically implanted within the eye following removal of the crystalline lens, during cataract surgery. While all modern IOLs attenuate the transmission of ultra-violet (UV) light, some IOLs, called blue-blocking or blue-light filtering IOLs, also reduce short-wavelength visible light transmission. The rationale for blue-light filtering IOLs derives primarily from cell culture and animal studies, which suggest that short-wavelength visible light can induce retinal photoxicity...

A 47-year-old male presented with bilateral 4 + circulating pigment in the anterior chamber, diffuse iris transillumination, dilated pupils unresponsive to light, and high intraocular pressure (IOP) levels in both eyes. Visual acuity and IOP improved bilaterally with topical steroid and antiglaucomatous therapy. In the 10th month, bilateral cystoid macular edema (CME) was developed and resolved after subtenon triamcinolone injections. CME recurred after cataract surgery in the right eye which was treated with intravitreal dexamethasone implant injection...

Purpose: The purpose of this article is to document the current practice pattern of Indian ophthalmologists for antibiotic prophylaxis in cataract surgery to prevent endophthalmitis. Methods: Fifteen structured questions were sent online to all ophthalmologists registered with the All India Ophthalmological Society. The questionnaire was divided into three main categories of prophylaxis - preoperative, intraoperative, and postoperative. A web-based anonymous survey was conducted, and a unique response link allowed completing the survey only once...

Purpose: The aim of this study was to study the effect of wet-laboratory training on the surgical outcome of resident performed manual small-incision cataract surgery (MSICS). Methods: We conducted a retrospective, comparative observational study on resident performed MSICS in our institute. We collected data of 464 patients of which Group A had 232 cases performed by residents without prior wet-laboratory training and Group B had 232 resident performed cases after adequate skill training in the wet laboratory...

Purpose: To gauge the differences in ophthalmology residency training, academic, clinical and surgical, in the last three decades of the 20th century and the first decade of the 21st century. Methods: A survey was conducted by the Academic and Research Committee of the All India Ophthalmological Society, in 2014-2016, using a prevalidated questionnaire, which was circulated to ophthalmologists to gauge the practicality of the teaching protocols of clinical and surgical skills during postgraduate residency program...

Purpose: To report the application of 25 MHz B-scan ultrasonography (MHzB) to determine the integrity of the posterior capsule (PC) in posterior polar cataract (PPC). Methods: Patients with whom PPC was clinically diagnosed using slit lamp microscopy who underwent 25 MHzB before phacoemulsification were retrospectively reviewed. The status of the PC was determined by 25 MHzB before phacoemulsification and confirmed during cataract surgery. Results: In total, 21 eyes in 14 clinically diagnosed PPC patients were enrolled in this study...

OBJECTIVE: To determine whether stereoscopic footage of cataract surgery could be captured with smartphones and to develop a procedure for editing and viewing the footage. The authors sought to measure whether subjectively convincing stereo footage could be captured with smartphones, whether it would be possible to sync this footage for stereoscopic viewing, and whether these tasks could easily be performed at lower cost than commercially available options.

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: We present two cases of late-onset capsular bag distension syndrome (CBDS). Observations: Two female patients were referred with decreased visual acuity and blurred vision. They had both undergone uncomplicated phacoemulsification and intraocular lens implantation into the capsular bag, seven and 13 years prior.Slit-lamp biomicroscopy and anterior segment optical coherence tomography demonstrated milky fluid between the intraocular lens and posterior capsules, consistent with late-onset capsular bag distension syndrome...

Purpose: To report two cases of panuveitis in immunocompetent patients in which cytomegalovirus was involved. Observation: Case 1 was a 46-year-old man who had a history of recurrent anterior chamber inflammations in his left eye. After Nd:YAG laser posterior capsulotomy, he developed panuveitis with vitreous haze and periphlebitis. Polymerase chain reaction (PCR) examination revealed the presence of cytomegalovirus (CMV) DNA in the anterior chamber (AC). He responded well to a series of intravitreal injections of ganciclovir (GCV)...

Purpose: To report a case with macular edema associated with uveitis, a decreased corneal endothelial cell density, and vitreous opacity caused by migrated intraocular antibiotic ointment after uneventful cataract surgery. Observations: A 63-year-old man underwent uneventful sutureless superior clear corneal phacoemulsification and implantation of an intraocular lens in his right eye. Eleven months later, he complained of blurred vision when he gazed downward. Three months later, uveitis, vitreous opacity, and retinal hemorrhage were noted...

Purpose: We report a case of pigment dispersion glaucoma secondary to uncomplicated phakic intraocular collamer lens (ICL) (Visian ICL™, Staar Inc., Monrovia, CA) implant that resulted in advanced visual field loss. Observations: A 50-year-old man presented for routine follow-up status post bilateral phakic intraocular collamer lens (ICL) placement 8 years earlier. He was incidentally found to have a decline in visual acuity from an anterior subcapsular cataract and elevated intraocular pressure (IOP) in the left eye...

I describe an intraoperative method for the consistent anchoring of the intraocular lens (IOL) and cataract surgery and on the patient's visual axis using coaxial microscope optics, surgeon-guided patient fixation, the precision pulse capsulotomy (PPC) device (Zepto) and utilizing the first (and fourth) Purkinje images. During surgery using a microscope with coaxial lights and optics, the patient is instructed to fixate on a given microscope light while the surgeon looks through the corresponding coaxial eyepiece...

PURPOSE: To determine whether the presence of vitreomacular interface abnormalities (VMIA) in patients with diabetic macular oedema (DMO) modifies the response to ranibizumab. METHODS: Medical records and spectral-domain optical coherence tomography (SD-OCT) scans of consecutive patients with centre-involving DMO initiating therapy with ranibizumab between December 2013 and March 2014 at the Belfast Health and Social Care Trust were reviewed. Patients were identified through an electronic database...

This paper investigates the automatic monitoring of tool usage during a surgery, with potential applications in report generation, surgical training and real-time decision support. Two surgeries are considered: cataract surgery, the most common surgical procedure, and cholecystectomy, one of the most common digestive surgeries. Tool usage is monitored in videos recorded either through a microscope (cataract surgery) or an endoscope (cholecystectomy). Following state-of-the-art video analysis solutions, each frame of the video is analyzed by convolutional neural networks (CNNs) whose outputs are fed to recurrent neural networks (RNNs) in order to take temporal relationships between events into account...

REVIEW

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...
