Purpose: This is a case report of a 31-year-old male patient presenting progressive and markedly asymmetric keratoconus treated with sequential intracorneal ring segment (ICRS) implantation followed by accelerated corneal cross-linking (CXL).
Observations: The follow-up after the last procedure revealed a thin, opacified cornea with an unexpected massive flattening of up to 20.3 D.
Purpose: Report a case where the patient desired spectacle independence after phacoemulsification and Descemet membrane endothelial keratoplasty (DMEK) due to Fuchs' endothelial dystrophy.
Observations: A 52-year-old female presented with corrected distance visual acuity (CDVA) of 20/40 in both eyes with low ametropia. Slit lamp examination revealed corneal edema 1+/4+, guttae, and nuclear cataract 2+/4+ in both eyes.
Purpose: The aim of this study was to determine anterior segment optical coherence tomography angiography (AS-OCTA) parameters to assess ocular redness severity.
Methods: AS-OCTA analyses of 60 eyes of 40 patients were grouped according to ocular redness stages using the 5-category validated bulbar redness scale in a cross-sectional retrospective study (groups 1-5). A subset of patients with slit-lamp photographs, total 35 eyes of 23 patients, were assessed with 10-category validated bulbar redness scale for comparison.
Purpose: Describe the utility of anterior segment optical coherence tomography angiography (AS-OCTA) to assess ocular surface lesions.
Methods: Retrospective, case-control study of 10 eyes of 9 patients with malignant lesions and 23 eyes of 22 patients with benign lesions. Lesions included 13 epithelial, 10 pigmented and 10 lymphoid lesions.
Purpose: Assessment of anterior segment-optical coherence tomography angiography (AS-OCTA) to determine severity of corneal neovascularization (CoNV).
Design: Retrospective, cross-sectional, single-center study.
Methods: Patients of various CoNV etiologies were selected and classified into mild, moderate, and severe.
Purpose: To clinically evaluate visual performance of the AcrySof IQ PanOptix TFNT00 and AT LISA tri 839MP intraocular lenses (IOLs) in binocular visual acuity (VA) and to characterize low-contrast visual performance at 6 months postimplantation.
Setting: Multicenter, 15 sites.
Design: Prospective, parallel-group, randomized, double-masked, postmarketing clinical study.
Purpose: To determine the utility of anterior segment optical coherence tomography angiography (AS-OCTA) in assessing limbal stem cell deficiency (LSCD).
Methods: Twenty-six eyes of 24 LSCD patients, classified clinically into stage I, II and III, and 12 eyes of 12 healthy subjects were included. AS-OCTA images were analyzed by two masked observers, measuring the maximum corneal vascular extension (CoVE) from the limbus to the furthest vessel over the cornea, and corneal vascular thickness (CoVT) from the most superficial to the deepest corneal vessel.
We report intraoperative finding of Granular Corneal Dystrophy Type-1 (GCD1) deposits after stromal pneumodissection in deep anterior lamellar keratoplasty (DALK) in a 61-year-old female. Pneumodissection was performed from the center to the periphery of the cornea, characterizing a big bubble type 1 technique which dissects the deep stroma from the predescemetic layer. After stromal removal, persistence of whitish deposits inside the predescemetic layer was noted.

Methods: Eight donor corneas from an eye bank were exposed to 25μl of 2.5% hydrofluoric acid (HF) solution on a filter paper for 20s.
Purpose: To report a case series of 4 patients with Descemet membrane detachment (DMD) after undergoing femtosecond laser-assisted cataract surgery incisions.
Methods: Case report.
Results: DMD was noted at the secondary incision (n = 2) or at the main incision (n = 2).
Objective: To assess the visual quality of life in patients with multiple sclerosis (MS), and to observe whether this parameter could be correlated to the findings of the ophthalmologic examination.
Method: The translated and validated 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25) was used to assess the visual quality of life. Clinical data on MS, visual acuity, visual fields, optic coherence tomography (OCT) and disc cupping were used for assessing correlation with VFQ-25.
Toric intraocular lens misalignment inducing astigmatism after refractive surgery.
J Refract Surg
September 2011
Purpose: To report the unexpected induction of astigmatism after phacoemulsification and toric intraocular lens (IOL) implantation in an eye with previous corneal refractive surgery.
Methods: Case report of a 46-year-old man with bilateral nuclear cataract and previous photorefractive keratectomy. Because corneal topography identified regular corneal astigmatism at the central optical zone, phacoemulsification and implantation of a one-piece hydrophobic acrylic toric IOL were performed.
