Erbium laser‐assisted ceramic debonding: a scoping review

Journal of Prosthodontics, Volume 31, Issue 9, Page e100-e124, December 2022., 2022
Abstract Purpose Removal of ceramic restorations and appliances can be time consuming, invasive, and inconvenient. Erbium lasers offer an alternative noninvasive method for debonding of ceramic appliances. This paper aims to provide a comprehensive review of current literature on the effectiveness of erbium lasers for removal of ceramic restorations ...

High sampling resolution optical coherence tomography reveals potential concurrent reductions in ganglion cell‐inner plexiform and inner nuclear layer thickness but not in outer retinal thickness in glaucoma

Ophthalmic and Physiological Optics, Volume 43, Issue 1, Page 46-63, January 2023., 2023
Abstract Purpose To analyse optical coherence tomography (OCT)‐derived inner nuclear layer (INL) and outer retinal complex (ORC) measurements relative to ganglion cell‐inner plexiform layer (GCIPL) measurements in glaucoma. Methods Glaucoma participants (n = 271) were categorised by 10‐2 visual field defect type.

Revisiting the oil droplet sign in keratoconus: Utility for early keratoconus diagnosis and screening

Ophthalmic and Physiological Optics, Volume 43, Issue 1, Page 83-92, January 2023., 2023
Abstract Purpose An annular dark shadow (ADS) reflex has been observed while performing direct ophthalmoscopy on subjects with keratoconus. This study describes a method that may serve as a diagnostic technique for early keratoconus and may be used as a quantitative measure of severity.

The relationship between baseline axial length and axial elongation in myopic children undergoing orthokeratology

Ophthalmic and Physiological Optics, Volume 43, Issue 1, Page 122-131, January 2023., 2023
Abstract Purpose To investigate the correlation between the baseline axial length (AL) and axial elongation in myopes undergoing orthokeratology (ortho‐k). Methods This was a retrospective study. During the 1‐year follow‐up, 1176 children (aged 8–14 years) were included and divided into an ortho‐k group (n = 588) and a single‐vision spectacle group (n =
