Keratitis produced by Aspergillus tamarii has been previously described associated to an ocular injury. We report a case in a contact lens wearer with a history of previous bilateral myopic LASIK ablation, bilateral intracorneal rings and vitrectomy and scleral buckling in his left eye. The fungus could be quickly identified combining phenotype, microscopy and mass spectrometry. Treatment with intravenous amphotericin, oral voriconazole, and topical amphotericin and natamycin and voriconazole was needed for corneal preservation...

PURPOSE: To report a series of cases of Acanthamoeba keratitis (AK) in scleral lens wearers with keratoconus to determine whether this type of contact lens presents a greater risk for development of infection. METHODS: This study reports three patients who wore scleral contact lenses to correct keratoconus and developed AK. The diagnoses of AK were established based on cultures of the cornea, scleral contact lenses, and contact lens paraphernalia. This study investigated the risk factors for infections...

PURPOSE: The purpose of this study is to evaluate the clinical outcomes in patients with traumatic pseudophacocele. METHODS: In this retrospective, interventional case series, scleral wound repair with pars plana vitrectomy and glued intrascleral fixation of an intraocular lens (glued IOL) was performed in 5 eyes of 5 patients. Pupilloplasty was performed in 3 cases whereas aniridia glued IOL fixation was done in 1 case that had total avulsion and loss of iris tissue...

PURPOSE: The purpose of the study was to report our initial experience with the transconjunctival Intrascleral Intraocular Lens (SFIOL) fixation with modified Yamane's double-needle technique and flanged haptics. METHODS: This was a prospective interventional study that enrolled 31 consecutive patients undergoing SFIOL with the modified Yamane's technique. All patients underwent comprehensive evaluation including uncorrected and best-corrected vision, intraocular pressure, ultrasound biomicroscopy, endothelial cell density, and macular thickness using optical coherence tomography (OCT)...

BACKGROUND: The dislocation of the crystalline lens is a common finding in patients with Marfan syndrome (MFS). Scleral intraocular lens (IOL) fixation is an accepted treatment method of this complication. To now, no long-term data on scleral IOL fixation in MFS exist. METHODS: We present a retrospective study of 27 eyes of 17 MFS patients that underwent scleral lens fixation at our clinic between 1999 and 2012. These patients are compared to an age- and surgeon-matched group of 31 eyes of 27 patients who underwent the same procedure for reasons other than MFS...

PURPOSE: To analyze clinical outcomes and intraocular pressure (IOP) control following scleral-glued intraocular lens (IOL) fixation in eyes with pseudoexfoliation (PXF). METHODS: A retrospective chart review and outcome analysis was performed on a series of eyes undergoing glue-assisted, scleral-fixated ('scleral-glued') IOL insertion in the setting of PXF and poor or absent capsular support. RESULTS: 28 eyes were included in the study. The indications for scleral-glued IOL fixation included late endocapsular IOL dislocation (21/28, 75%), exchange for iris-fixated IOL due to complication (4/28, 14%), subluxed crystalline lens (2/28, 7%), and aphakia after complicated cataract surgery (1/28, 4%)...

Тhe prevalence of complications associated with the deficiency or absence of capsular support in cataract patients is 5-15%. Moreover, approximately 20% of patients have an inconspicuous zonular weakness, which is often left undetected preoperatively. AIM: to classify and comparatively analyze the latest published data on the outcomes of various kinds of complicated cataract surgery. MATERIAL AND METHODS: Analysis of available literature on the subject of research published in 2003-2016...

Purpose: To review long time treatment results in patients with small or medium sized choroidal melanoma who underwent surgical tumor endoresection as a primary treatment when plaque radiotherapy was unable and patients declined enucleation. Materials and methods: Patients were evaluated for best corrected visual acuity (BCVA), and underwent biomicroscopy, indirect ophthalmoscopy, retinography and ultrasound as well as the usual systemic workup. Study inclusion required the absence of scleral invasion or metastasis and an anterior margin not exceeding the pars plana or the ciliary body...

PURPOSE: To evaluate probable complications of ArtificialIris implantation with iris fixated intraocular lens. METHOD: Development of photophobia, glare, and psychological strain during face-to-face communication in a 23-year-old man with a widespread traumatic iris defect terminate to make a decision for performing implantation of an ArtificialIris (Humanoptics, Erlangen, Germany) under the remnant iris without removing the patient's existing Artisan lens. RESULTS: Without any intraoperative or postoperative complications, the patient's visual acuity increased by 1 line, the endothelial cell loss was comparable with the cell loss associated with standard cataract surgery, and the anterior-chamber depth and anterior-chamber anatomy did not change...

BACKGROUND/AIMS: The purpose of this study was to compare and evaluate the visual outcome and complications of various techniques of secondary intraocular lens (IOL) (i.e., anterior chamber IOL [ACIOL], suture-fixated posterior chamber IOL [PCIOL], and glue-fixated PCIOL). STUDY DESIGN AND SETTING: This was a randomized, prospective, interventional, comparative, clinical trial study. SUBJECTS AND METHODS: Patients of either sex having aphakia and lacking posterior capsular support were included in the study, and patients having corneal or scleral pathology, optic atrophy, uncontrolled glaucoma, retinal detachment, and other retinal pathology were excluded from the study...

Purpose: This study investigated the anterior ocular anatomic origin of high-order aberration (HOA) components using optical coherence tomography and a Shack-Hartmann wavefront sensor. Methods: A customized system was built to simultaneously capture images of ocular wavefront aberrations and anterior ocular biometry. Relaxed, 2-diopter (D) and 4-D accommodative states were repeatedly measured in 30 young subjects. Custom software was used to correct optical distortions and measure biometric parameters from the images...

REVIEW
Mohammad Ali Zare Mehrjerdi, Masomeh Mohebbi, Mehdi Zandian
Presbyopia is the primary cause of reduction in the quality of life of people in their 40s, due to dependence on spectacles. Therefore, presbyopia correction has become an evolving and rapidly progressive field in refractive surgery. There are two primary options for presbyopia correction: the dynamic approach uses the residual accommodative capacity of the eye, and the static approach attempts to enhance the depth of focus of the optical system. The dynamic approach attempts to reverse suspected pathophysiologic changes...

BACKGROUND: To report the use of scleral lens (ScCL) to improve vision in patients having keratoconus who had intracorneal ring segment (ICRS) surgery. METHODS: Two eyes of two keratoconus patients fitted with ScCL (PROSE - prosthetic replacement of the ocular surface ecosystem, USA) after having undergone ICRS surgery are reported as noncomparative interventional case series. The ICRS implanted were INTACs and kerarings. Indications, visual acuity with ScCL, complications and follow-up are reported...

PURPOSE: To present the management of three patients suffering from ptosis of various etiologies, with scleral contact lenses. MATERIAL AND METHODS: Three patients (five eyes) with ptosis resulting from levator dehiscence due to long-term rigid gas permeable contact lens wear for keratoconus, phthisis bulbi, and myopathy due to Kearns-Sayre syndrome were identified during a 2-year period. They were fitted with scleral contact lenses in order to provide cosmesis by lifting the upper eyelid with the bulk of the lens, and simultaneously provide vision correction where applicable...
