We report a case of bilateral cataract surgery performed in a 21-year-old western lowland gorilla. Phacoemulsification with intraocular lens insertion was performed using standard human surgical equipment. Visual function significantly improved. She subsequently mated and gave birth. Ultimately, cataract surgery enabled the birth of a baby gorilla.

Retinoblastoma is the most common intraocular malignant tumor of childhood. Intra-arterial chemotherapy (IAC) is a recently popularized technique used for the treatment of retinoblastoma, to decrease mortality, increase preservation of the eye, and prevent blindness. Along with the extensive use of IAC, it is important to apply noninvasive examination methods to assess the activity of the tumor and the risk factors for disease dissemination without histopathological confirmation. There are few studies that have assessed the value of magnetic resonance imaging (MRI) in evaluating the efficacy and complications of IAC for retinoblastoma...

PURPOSE: Implanting intraocular lens (IOL) in proper direction is important in cataract surgery to reduce the possibility of undesirable complications. We experienced a case who underwent vitrectomy combined with cataract surgery and developed secondary angle closure glaucoma caused by IOL misdirection. Goniosynechialysis (GSL) and repositioning of IOL successfully ameliorated the high intraocular pressure (IOP). CASE REPORT: A 64-year-old male with massive vitreous hemorrhage underwent vitrectomy combined with cataract surgery...

Objective: To compare visual quality and satisfaction after multifocal toric intraocular lens (Acrysof IQ Restor toric, ART) and monofocal toric intraocular lens implantation in patients. Methods: It was a prospective nonrandomized Phase Ⅲ clinical trial. Patients with age-related cataract and corneal astigmatism were enrolled and accepted phacoemulsification combined with implantation of intraocular lens (IOL) in Henan Provincial Eye Hospital during March 2013 to December 2014. Fifty-six cases were divided into two groups according to which IOL they chose...

Objective: To observe the long-term outcomes after congenital cataract surgery performed prior to 36 months of age. Methods: A retrospective case study was conducted. Thirty-two cases (57 eyes) of congenital cataract were included from January 2004 to January 2012. All patients received intraocular lens (IOL) implantation with posterior continuous curvilinear capsulorhexies and anterior vitrectomy after cataract extraction and were followed up. At the last visit, the best corrected visual acuity (BCVA) was determined and postoperative complications were evaluated during follow-up with a longest time of 13 years...

Objective: To discuss the correlation between axial length and corneal curvature and corneal spherical aberration in a group of cataract patients with axial length greater than 24 mm. Methods: Retrospective case series. This study comprised 117 (234 eyes) age-related cataract patients. There were 51 men (43.59%) and 66 women (56.41%) with mean age of (69.0±8.7) years (range from 52.0 to 85.0 years). The average axial length was 27.6±1.8 (range from 24.2 to 31.9 mm).

The occurrence of multifocal intraocular lens (MIOL) is known as an important period in the development of cataract surgery, which can provide a simultaneous vision without the use of spectacles or contact lenses. However, in the current stage, MIOL implantation may also lead to decreased visual acuity and increased risk of photic phenomena, thus in some instance a second procedure to exchange the MIOL is necessary. Optimizing visual outcomes of MIOL implantation and controlling adverse effects has become the focus for ophthalmologists...

We describe a technique to prevent late intraocular lens (IOL) subluxation and dislocation that can be associated with progressive zonulopathy. Supracapsular glued IOL fixation is done to retain an intact anterior hyaloid face and avoid vitreous disturbance while providing stable long-term IOL fixation. Phacoemulsification is followed by glued IOL implantation above intact anterior and posterior capsules. Sclerotomies are created ab interno in a supracapsular plane under diametrically opposite lamellar scleral flaps without entering the vitreous cavity...

Bartonella species, vector-borne etiologic agents of many systemic or self-limited infections, are responsible for a widening spectrum of diseases in humans, including inflammatory conditions of the eye. The aim of this study was to determine whether there is any relationship between uveitis and the evidence of Bartonella spp. infection in the serum, ocular fluid, and cataract mass in patients with intraocular inflammation. Polymerase chain reaction (PCR)-based tests and DNA sequencing were performed on surgery-extracted specimens of intraocular fluid and lens mass of 33 patients...

PURPOSE OF REVIEW: Descemet membrane endothelial keratoplasty (DMEK) has become a first-line treatment in corneal endothelial diseases because of its exceptional clinical outcomes and low complication rates. Because of its improved refractive predictability, DMEK is now also considered for managing cases with endothelial decompensation following previous refractive procedures, or in combination with those. This article reviews the clinical outcomes in these cases and discusses the possibility of refractive interventions following DMEK...

BACKGROUND: The purpose of this study was to evaluate the characteristics and outcomes of cataract surgery with/without vitrectomy in patients with pars planitis who received immunosuppressive therapy. METHODS: This was a retrospective case series, single-center study. Twenty-two patients with pars planitis who received immunosuppressive therapy were included, with a median age at presentation of 9.5 years, having had cataract surgery. The following data was collected: age at presentation and at cataract surgery, time of follow-up, best-corrected visual acuity (BCVA) before the surgery and at 1 week, 1 and 6 months after the procedure, immunosuppressive therapy, complications and causes for failed visual improvement...

BACKGROUND: Independence from all optical aids, and freedom from unwanted symptoms, following cataract and lens surgery remains the ultimate goal of both patient and surgeon. The development of trifocal IOL technology provides an ever-increasing range of options. The purpose of our study is to understand the predictability, safety and efficacy of a new trifocal intraocular lens (IOL) following cataract or refractive lens exchange (RLE) surgery. METHODS: This was a retrospective consecutive case series of patients undergoing cataract extraction or RLE followed by implantation of the Alcon IQ Panoptix IOL...

AIM: To evaluate the surgical treatment and visual outcomes of eyes with cataract and persistent hyperplastic primary vitreous (PHPV). METHODS: This retrospective study included patients with cataract and PHPV treated with various strategies. Anterior PHPV was treated using phacoemulsification with underwater electric coagulation on posterior capsule neovascularization, posterior capsulotomy, anterior vitrectomy, and intraocular lens (IOL) implantation. Posterior PHPV was treated with lensectomy, posterior vitrectomy, retinal photocoagulation, and IOL implantation or silicone oil tamponade...
