Evaluation of In Vitro Wettability of Soft Contact Lenses Using Tear Supplements
Objective: To evaluate the interaction between tear supplements and soft contact lenses (SCLs), we measured the contact angles (CAs) on the SCLs using commercially available tear supplements. Methods: We used four daily disposable conventional hydrogel lenses (etafilcon A, etafilcon A+ polyvinylpyrrolidone, nelfilcon A, and omafilcon A containing 2-methacryloyloxyethyl phosphorylcholine [MPC]) and four silicone hydrogel lenses (narafilcon A, senofilcon A, delefilcon A, and stenfilcon A). The CAs on the SCLs were measured using a sessile drop technique and four different types of sessile drops, including saline, ...

Ocular Surface Biomarkers
Abstract: Sjögren syndrome (SS) is a chronic inflammatory autoimmune disease of the lacrimal and salivary glands. Salivary gland biopsy is still one of the most valuable and acceptable diagnostic tests for SS, which however, is an invasive test. Therefore, noninvasive diagnostic biomarkers with high specificity and sensitivity are required for the diagnosis and assessment of SS. Because ophthalmological testing constitutes to an important part for the diagnosis of SS. Tears harbor biomarkers with a high potential to be used for differential diagnosis and assessment of treatment in many systemic disorders, including SS...

Modified Contact Lens Sandwich Technique of Glue for Management of Medium to Large Corneal Perforations in the COVID Era
Abstract: The aim of this article is to describe a novel technique of gluing as an interim measure to provide tectonic support in cases of medium-sized to large-sized (3–6 mm) corneal perforations. Five eyes of five patients in which conventional cyanoacrylate glue application was not feasible, and therapeutic keratoplasty could not be performed in view of the unavailability of corneal tissues were included. Surgery to maintain integrity of the globe was performed, and a therapeutic keratoplasty was performed on tissue availability (mean interval of 7.4 days). On follow-up, all patients had a well-formed anterior cha...

Intrastromal Descemet Membrane Transplantation as a Potential Alternative to Bowman Layer Inlays in Eyes With Advanced Keratoconus
Abstract: Herein, we report the outcomes of intrastromal Descemet membrane (DM) transplantation in corneas with advanced keratoconus. Three eyes (three patients) showed advanced keratoconus. No eye underwent prior UV-cross-linking or any other ocular surgery. In all eyes, A donor DM was implanted into a mid-stromal pocket and clinical outcomes were evaluated up to 24 months after surgery. All procedures were uneventful. Up to 24 months postoperatively, the DM graft was well-positioned and barely visible within the recipient stroma; all corneas were clear. No eye showed signs of keratoconus progression throughout the fo...

Precision Pulse Capsulotomy During Combined Penetrating Keratoplasty With Cataract Surgery and Intraocular Lens in Small Nondilating Pupil
Conclusions: The PPC device facilitates creation of a smooth, round, and appropriately sized anterior capsulotomy in open-sky surgeries, particularly in presence of small nondilating pupils. (Source: Eye and Contact Lens: Science and Clinical Practice)

Tolerance to Residual Refractive Errors After Trifocal and Trifocal Toric Intraocular Lens Implantation
The objective of this study was to assess the impact of 0.50 diopter (D) positive or negative defocus on visual function in patients implanted with trifocal and trifocal toric intraocular lenses (IOLs). Methods: The study included patients implanted with the AcrySof IQ PanOptix IOL or the PanOptix Toric. Visual acuity (VA) at high (100%), medium (50%) and low (10%) contrast, contrast sensitivity function (CSF), and halo perception were assessed three months after surgery. Explorations were performed with corrected distance visual acuity (CDVA), with a positive defocus of +0.50D (myopization) and with a negative defo...

Intraocular Lens Power Calculation Without Corneal Parameters: A New Option
Conclusions: The new calculated regression formulas seem to represent a reliable method to calculate the R when it is undetectable, as in case of corneal dystrophies. (Source: Eye and Contact Lens: Science and Clinical Practice)

Ocular Anterior Segment Pathology in the Emergency Department: A 5-Year Study
Conclusions: Most ocular conditions that present in the ED are nonurgent and can be treated in an outpatient setting. However, ED personnel are often unable to obtain the proper “ocular vital signs” (the VA and IOP) and diagnoses. Our findings suggest a need for clear interprofessional discussion in creating an algorithm for triage and the management of eye conditions in the ED to deliver effective care.

Analysis of Corneal Densitometry and Endothelial Cell Function in Fuchs Uveitis Syndrome
Objectives: To evaluate corneal densitometry and endothelial cell properties in patients with unilateral Fuchs uveitis syndrome (FUS), and to compare results with unaffected contralateral eyes and healthy control subjects. Methods: A total of 90 participants were included in this prospective cross-sectional study. Forty-five affected eyes of patients with FUS were regarded as group 1 (FUSa), 45 fellow eyes were regarded as group 2 (FUSf), and 45 healthy-control eyes were regarded as group 3. Corneal densitometry was measured with densitometry software of Scheimpflug Corneal Topography (Pentacam HR, Oculus GmbH, ...

Agreement of Corneal Endothelial Cell Analysis Between Konan-Noncon Robo SP-6000 and Tomey EM-3000 Specular Microscopes in Healthy Subjects
Conclusions: The difference in endothelial cell measurements between the Konan SP-6000 and the Tomey EM-3000 specular microscopes through the center and the L-count analyzing techniques, respectively, is clinically small and not statistically significant. Nevertheless, caution should be taken when used interchangeably because ECD difference between the two machines can be as high as 525.4 cells/mm2.
