Background This study aimed to examine the factors predicting participants' intention to use telemedicine during the COVID-19 pandemic. Interest in health information technologies (HITs) has increased due to COVID-19. Most studies have focused on the acceptance of HIT by physicians and nurses, while there is a lack of studies on patients' perception and acceptance of such systems in ophthalmology.

Contact lens wear and poor contact lens hygiene significantly increase the risk of corneal infection. This study aimed to determine the level of contact lens hygiene awareness amongst contact lens wearers attending our service and determining whether contact lens type and hygiene attitude are related to severity of disease.

Methodology A total of 21 eyes from 21 patients with RCES either following trauma or spontaneously due to underlying anterior basement membrane dystrophy (ABMD) were prospectively enrolled over a six-month period. The acute episode was managed with topical sodium chloride 5% ophthalmic ointment applied twice daily for 30 days.

Methods: A corneoscleral button was obtained from an infant donor and a DSAEK graft was prepared using a microkeratome. In comparison to the standard technique of DSAEK graft preparation some modifications were made in order to avoid inadvertent perforation, as the donor cornea had a very spherical shape, probably due to the very young age of the donor.
Congenital aniridia is a rare condition affecting a wide range of ocular structures, from the ocular surface to the retina. We present the case of a 59-year-old woman with PAX6- and WT1-negative congenital aniridia who developed aniridia-associated keratopathy and progressive endothelial dysfunction with corneal decompensation after cataract surgery. The patient underwent successful ultrathin Descemet stripping endothelial keratoplasty.

Twenty-five percent of adults will develop the disease during their lifetime with the risk increasing to one in two over the age of 50. Herpes zoster ophthalmicus presents with a plethora of ocular manifestations ranging from the characteristic rash in the distribution of the ophthalmic branch of the fifth cranial nerve to more severe keratouveitis, disciform keratitis, and even retinal necrosis.

Quantification of the associated inflammatory response may provide insight into the pathogenesis of BK and guide treatment options. In this exploratory study, we evaluated 45 BK patients and 20 healthy controls by optical coherence tomography and pro-inflammatory tear cytokine analysis.

Pediatric PK is reserved for cases with advanced pathology or dysfunction as rejection and failure rates greatly supersede the rates of adult PK. The objective was to identify factors associated with graft rejection and failure amongst Mexican children undergoing primary PK for different indications.

Materials And Methods: All grafts were obtained from Dr Agrawal Hospital's Eye Bank. Air injection was the initial preferred mode of graft harvest.
Fermionization is what happens to the state of strongly interacting repulsive bosons interacting with contact interactions in one spatial dimension. Crystallization is what happens for sufficiently strongly interacting repulsive bosons with dipolar interactions in one spatial dimension. Crystallization and fermionization resemble each other: in both cases - due to their repulsion - the bosons try to minimize their spatial overlap.

Methods: Retrospective analysis of patients with choroidal melanotic lesions. In total, 87 eyes fulfilled our inclusion criteria.
Purpose: To report a case with multiple macroperforations and a double anterior chamber (AC) after predescemetic deep anterior lamellar keratoplasty.
Methods: A patient was referred after undergoing complicated excision of pseudopterygium that extended onto the cornea. At presentation, an eccentric lamellar patch graft extending over the pupillary axis with a double AC was seen.
Purpose: To assess the psychological status of keratoconus sufferers and to determine the relationship between depression and visual impairment in this group of patients.
Methods: Fifty-six patients with keratoconus and forty-seven age- and gender-matched healthy control subjects were retroprospectively analyzed. Every participant underwent a complete ophthalmological examination.
