PURPOSE: To analyze risk factors for refractive error after cataract surgery and provide a benchmark for refractive outcomes after standard cataract surgery. SETTING: One hundred cataract surgery clinics from 12 European countries. DESIGN: Multicenter database study. METHODS: Data on consecutive cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery between January 1, 2014 and December 31, 2015 were analyzed in terms of demographics, preoperative corrected distance visual acuity (CDVA), target refraction, coexisting eye diseases, surgical difficulties including previous ophthalmic interventions, type of surgery, intraocular lens (IOL), and surgical complications...

PURPOSE: To evaluate the benefit of the Holladay 2 formula versus the 3rd generation formulae in calculating the IOL power in eyes with non-standard axial length or keratometry before cataract surgery. PATIENTS: Retrospectiv study from January to December 2015. The inclusion critaeria were axial length (AL) <22mm or >26mm, or average keratometry <42 D or >46 D, dividing the patients in 4 groups respectively. The 7 parameters required to calculate the Holladay 2 formula were collected...

PURPOSE: To analyze the refractive predictability of low-power and medium-power toric intraocular lenses (IOL) during cataract surgery. METHODS: A retrospective case series. Patients with low and moderate degrees of astigmatism were treated with either an Alcon AcrySof IQ toric monofocal lens (SN6AT2 or SN6AT3) or a Zeiss toric monofocal lens (709 MP + 1 D or 709 MP + 1.5 D). They were divided into two groups: group 1 with low-power toric IOL (n = 40, SN6AT2 and 709 MP + 1), group 2 with medium-power toric IOL (n = 70, SN6AT3 and 709 MP + 1...

BACKGROUND: Investigating the efficacy and safety of phacoemulsification with intraocular lens (IOL) implantation in corneal opacities. METHODS: This retrospective study was conducted in a tertiary medical center. Twenty-three eyes of 19 patients with cataracts and corneal opacities obscuring the pupillary center having received phacoemulsification with IOL insertion without any ancillary techniques were enrolled. The primary study outcome measures were uncorrected and best corrected visual acuity (BCVA), and complications...

We describe a new technique to prevent an endothelial donor graft from dropping into the vitreous cavity during non-Descemet stripping automated endothelial keratoplasty (nDSAEK) for extremely mydriatic bullous keratopathy (BK) eyes without capsular support. The patient was a 79-year-old woman who underwent nDSAEK for an extremely mydriatic BK eye with an incomplete barrier between the anterior and posterior chambers. She had undergone argon laser iridotomy for acute glaucoma at the age of 59 years and cataract surgery 3 years later...

Intraocular lens (IOL) dislocation is a rare complication of cataract extraction requiring prompt surgery. This case report aims to raise awareness of such cases and the importance of post-surgery follow-up. A 58-year-old female patient was found with anterior IOL dislocation a week after phacoemulsification surgery in her right eye. Visual acuity of the right eye was 1/60 with ciliary injection and IOL dislocation to the anterior chamber of the right eye. The patient underwent surgery of the right eye and the IOL haptic was found to be broken...

We present a case of posterior capsular defect with traumatic cataract after blunt trauma in which an extended focal length intraocular lens (IOL) was implanted in the bag after conventional phacoemulsification and anterior vitrectomy. Anterior segment optical coherence tomography performed preoperatively aided in the confirmation and documentation of the capsular integrity. Intraoperative trocar anterior chamber (AC) maintainer allowed AC maintenance without further complications. IOL was well centered postoperatively at 6 months, and the unaided visual acuity was 20/20 for distance and N8 for near...

AIM: To evaluate the efficacy and safety of the excimer laser correction of the residual refractive errors after cataract extraction with intraocular lens (IOL) implantation in uncommon cases. METHODS: Totally 24 patients with high residual refractive error after cataract surgery with IOL implantation were examined. Twenty-two patients had a history of phacoemulsification and IOL implantation, and two had extra-capsular cataract extraction with IOL implantation...

Intraocular lens (IOL) opacification is rare but may occur after non-Descemet stripping automated endothelial keratoplasty (n-DSAEK) or intravitreal air injection after pars plana vitrectomy (PPV). We reported two cases of IOL opacification within the pupillary region. Chart was retrospectively reviewed. The predisposing factors and the visual acuity were analyzed. The opacification was evaluated by anterior segment optical coherence tomography (AS-OCT). A 68-year-old healthy woman with pseudophakic bullous keratopathy underwent uneventful n-DSAEK in the right eye...

The aim of this study was to compare the safety and efficacy between the prechopping method using a Reverse Chopper (iHPC) and the routine stop-and-chop (RSC) method in phacoemulsification of cataracts with grade IV hard nuclei (HNC (≥IV)). A total of 32 patients (32 eyes) scheduled for Phaco combined with intraocular lens (Phaco-IOL) for HNC (≥IV) from March 2015 to January 2016 were enrolled and randomly divided into two groups (the iHPC group, n=16 and the RSC group, n=16) so as to compare the effective intraoperative Phaco time, corneal edema 1-3 days after surgery, best corrected visual acuity (BCVA), and rate of loss of corneal endothelial cells (CECs) 1 month after surgery...

BACKGROUND: During cataract surgery, maintaining an adequate degree of mydriasis throughout the entire operation is critical to allow for visualisation of the capsulorhexis and the crystalline lens. Good anaesthesia is also essential for safe intraocular surgery. Mydrane® is a new injectable intracameral solution containing two mydriatics (tropicamide 0.02% and phenylephrine 0.31%) and one anaesthetic (lidocaine 1%) that was developed as an alternative to the conventional topical pre-operative mydriatics used in cataract surgery...

BACKGROUND: Although cataract surgery is a well-established and standardised procedure, it can be demanding and associated with higher complication rates in high hyperopia. We present clinical data for highly hyperopic patients who underwent cataract surgery over a 12-year period (2005 - 2016) and at a single centre. PATIENTS AND METHODS: Out of a total of 11 434 cataract operations, 41 highly hyperopic eyes (SN60AT ≥ 31 dpt) were included for analysis...

Frank Sachers, David Goldblum
BACKGROUND: Capsulorhexis is one of the most important steps in cataract surgery. Good centration, circular overlap in sufficient size and a circular edge without tears result in good centration of the intraocular lens (IOL). In this study, the capsulorhexis results of an experienced surgeon are compared with reported data in femtolaser assisted cataract surgery (FLACS). PATIENTS AND METHODS: 105 consecutive operations were photographically documented; in 81 cases size and overlap were analysed retrospectively...

Jocelyn Lam, Bradley Sifrig, Hoon Jung
Purpose: We report an unusual case of rapid and severe anterior capsular contraction associated with secondary intraocular lens (IOL) dislocation following cataract surgery in a patient with unspecified rod-cone dystrophy. Case Report: A 68-year-old woman with a history of uncharacterized bilateral rod-cone dystrophy presented with blurry vision 1 month after cataract surgery. Best corrected visual acuity was 20/40 in the operative eye. Slit-lamp exam showed severe anterior capsular phimosis limiting view of the fundus...

Purpose: We report here the case of a patient with anterior segment migration of intravitreal dexamethasone implant as well as its management and outcome. Methods: The patient had the following sequence of events: complicated cataract surgery, iris-sutured intraocular lens implant, followed by cystoid macular edema treated with intravitreal Avastin, retinal vein occlusion treated with intravitreal dexamethasone implant, corneal decompensation treated with Descemet stripping automated endothelial keratoplasty (DSAEK), and finally recurrence of macular edema treated with repeated intravitreal dexamethasone implant...
