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...

Purpose: To compare toric intraocular lens (IOL) alignment assisted by image-guided surgery or manual marking methods and its impact on visual quality. Patients and methods: This prospective comparative study enrolled 80 eyes with cataract and astigmatism ≥1.5 D to undergo phacoemulsification with toric IOL alignment by manual marking method using bubble marker (group I, n=40) or Callisto eye and Z align (group II, n=40). Postoperatively, accuracy of alignment and visual quality was assessed with a ray tracing aberrometer...

OBJECTIVE: Optimal management of pregnancies at 39 weeks gestational age is unknown. Therefore, we sought to perform a comparative effectiveness analysis of elective induction of labor (eIOL) at 39 weeks among nulliparous women with non-anomalous singleton, vertex fetuses as compared to expectant management (EM) which included IOL for medical or obstetric indications or at 41 weeks in undelivered mothers. MATERIALS AND METHODS: A Monte Carlo micro-simulation model was constructed modeling two mutually exclusive health states: eIOL at 39 weeks, or EM with IOL for standard medical or obstetrical indications or at 41 weeks if undelivered...

BACKGROUND: To introduce a novel surgical technique for optic capture by residual capsular opening in secondary intraocular lens (IOL) implantation and to report the outcomes of a long follow-up. METHODS: Twenty patients (20 eyes) who had received secondary IOL implantation with the optic capture technique were retrospectively reviewed. We used the residual capsular opening for capturing the optic and inserted the haptics in the sulcus during surgery. Baseline clinical characteristics and surgical outcomes, including best-corrected visual acuity (BCVA), refractive status, and IOL position were recorded...

REVIEW
Eric Nudleman, Yoshihiro Yonekawa, Jonathan L Prenner
PURPOSE OF REVIEW: The surgical approach to eyes needing a secondary intraocular lens have evolved rapidly in recent years. Here, we will focus on techniques for scleral-fixation of intraocular lenses (IOLs), and will review the evidence for their safety and efficacy. RECENT FINDINGS: Transscleral fixation of IOLs refers the placement of lens haptics within scleral tunnels to stabilize the lens in eyes that lack adequate capsular support. Various surgical techniques have been reported recently to accomplish this goal...

PURPOSE: To externally validate the Wang-Koch method for optimization of intraocular lens (IOL) formulas. SETTING: TLC Laser Eye Centre, Mississauga, Ontario, Canada. DESIGN: Retrospective case series. METHODS: Consecutive cataract patients with an axial length (AL) of 25.0 mm or longer were recruited. The predicted postoperative spherical equivalents (SEs) calculated from the Holladay 1 formula were compared with the 3-week postoperative SEs to yield prediction errors for Wang-Koch adjusted and unadjusted ALs...

Intraocular foreign body (IOFB) in cases of penetrating eye injury accounts for an important indication of vitreoretinal intervention following ocular trauma. Vascular occlusion as a complication of IOFB is rare. Here we present a case of a 34-year-old male with post-traumatic cataract and an intraocular metallic foreign body (IOFB) lodged in the superficial layers of the retina inferotemporal to the disc, causing an inferotemporal branch retinal artery occlusion. The case was managed by lensectomy with pars plana vitrectomy and IOFB removal followed by a second procedure of secondary IOL implantation...

Purpose: We report a case of corneal endothelial graft failure secondary to dexamethasone intravitreal implant (Ozurdex™) migration into the anterior chamber (AC). Observations: A 53-year-old man with a history of bilateral idiopathic chronic uveitis, had a right anterior vitrectomy and AC intraocular lens (ACIOL) with a peripheral iridotomy. He received an intravitreal Ozurdex™ implant for right cystoid macular oedema (CMO). Three months later he developed pseudophakic bullous keratopathy and underwent a Descemet stripping automated endothelial keratoplasty (DSAEK), combined with IOL exchange (ACIOL explantation followed by scleral fixated posterior chamber IOL)...

PURPOSE: To describe surgical outcomes and structural characteristics of intraocular lenses (IOLs) implanted with transconjunctival sutureless intrascleral (SIS) fixation in human eyes. DESIGN: Retrospective interventional surgical case series involving live and cadaveric human eyes. METHODS: In this study, we investigated the surgical outcomes and structural anatomy of secondary IOLs implanted with the SIS technique in human eyes. All cases involving SIS IOL fixation performed at a single academic center from January 1, 2012, through July 30, 2016, were reviewed to describe the surgical technique, common indications, clinical outcomes, and the rate of common operative complications...

A 55-year-old female with an aphakic nanophthalmic eye underwent a secondary intraocular lens implantation (IOL) with double Artisan aphakia iris claw IOLs (ICIOLs) and was evaluated in this research. The patient's preoperative best-corrected visual acuity (BCVA) of the right eye was 0.4 (0.4 logMAR) (with + 21.00 D), postoperative 1st and 3rd month, 1st year, and 3 years BCVAs were 0.4 (0.4 logMAR). The intraocular pressure was 15 mmHg preoperatively, and 14, 12, 12, and 15 mmHg postoperatively at 1st and 3rd month, 1st year, and 3 years, respectively...

PURPOSE: Monofocal aspheric intraocular lenses (IOLs) provide better visual outcome compared to other available IOLs following cataract surgery. However, the imported IOLs are expensive and are not affordable by all subset of patients in low- to middle-income countries like India. The aim of this study is to compare the safety and efficacy of a relatively low cost indigenous IOL (Acriol EC) with an imported aspheric IOL (AcrySof IQ). METHODS: A randomized controlled trial was conducted at a tertiary care centre...

REVIEW
Priya Narang, Amar Agarwal
Glued intrascleral haptic fixation of an intraocular lens (glued IOL) has evolved as a technique with various modifications that are adopted and practiced by several surgeons. With adequate and appropriate haptic tuck, glued IOL imparts a stable IOL fixation and is a secured method of secondary IOL placement with no pseudophacodonesis.
