Introduction: To assess the efficacy and safety of the combination of microblepharoexfoliation (MBE), intense pulse light (IPL) and meibomian gland expression (MGX) for treatment of meibomian gland dysfunction (MGD).

Methods: This was a prospective, parallel-control trial conducted from April 2022 to January 2023. Participants were assigned to receive either three sessions of MBE-IPL-MGX treatment and home-based therapy (treatment group) or home-based therapy alone (control group).

Purpose: To determine the efficacy and safety of eyelid exfoliation treatment in dry eye disease (DED), blepharitis, and contact lens (CL) discomfort patients.

Methods: A systematic review that included only full-length randomized controlled studies, reporting the effects of eyelid exfoliation treatment in 2 databases, PubMed and Web of Science, was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The search period was between October 29, 2022 and December 6, 2022.

Purpose: To compare the efficacy of epithelium-off corneal collagen crosslinking (CXL) with transepithelial CXL in patients with progressive keratoconus with a follow-up of 3 years, taking into account the patients' age and the location of the corneal ectasia.

Methods: In this prospective study participated 64 eyes with progressive keratoconus were included in this long-term study, of which 31 eyes were treated by epithelium-off CXL and 33 by transepithelial CXL. All of the patients with a follow-up of 36 months were evaluated for visual variables (corrected distance visual acuity (CDVA), corneal aberrations, and corneal densitometry), structure variables (astigmatism, keratometry, corneal asphericity, maximum posterior elevation, corneal thickness, and corneal volume), and keratoconus index variables.

Posterior chamber phakic intraocular lens (pIOL) implantation is a common option for correcting moderate-to-high ocular refractive defects. Because this pIOL is implanted on ciliary sulcus, the distance between the back surface of the pIOL and the anterior surface of the crystalline lens, that it is known as vault, should be measured in different conditions to ensure the technique's safety. Cyclopentolate is a drug that dilates the pupil and relaxes accommodation (cycloplegia).

A Statement Of Significance: For the first time, this study shows that corneas that previous undergone orthokeratology treatment do not respond differently to LASIK compared with previous soft contact lens wear experience.

Purpose: To evaluate and compare the corneal morphology and visual outcomes of long-term soft and orthokeratology (OK) contact lens fitting in wearers undergoing corneal refractive surgery (LASIK) for myopia correction.

Methods: Sixteen (16) myopic patients wearing hydrophilic soft contact lens (SCL, n = 8 subjects, control group) and OK (n = 8 subjects, OK group) lenses who undergone LASIK were retrospectively evaluated.

Purpose: To evaluate the binocular and accommodative function in children wearing dual focus (DF) MiSight® contact lenses (CLs) for myopia control compared with children wearing single-vision (SV) spectacles.

Methods: This was a randomized, controlled clinical trial involving subjects aged 8 to 12, with myopia ranging from - 0.75 to - 4.

Objectives: To assess the relative clinical success of MiSight contact lenses (CLs) (study group) and distance single-vision (SV) spectacles (control group) in children in terms of adverse events (AEs), discontinuations, and tear film osmolarity over a 2-year period.

Methods: Seventy-four subjects aged 8 to 12 with myopia of -0.75 to -4.

Objectives: Recent research has shown that concentric contact lenses (CLs) can be a way to control the progression of myopia. The purpose of the current study was to compare vision-related quality-of-life measures in children wearing distance single-vision (SV) spectacles versus MiSight CLs, a specific concentric design for myopia control.

Methods: Subjects aged 8 to 12 with myopia from -0.

Purpose: To assess the relationship between short-term and long-term changes in power at different corneal locations relative to the change in central corneal power and the 2-year change in axial elongation relative to baseline in children fitted with orthokeratology contact lenses (OK).

Methods: Thirty-one white European subjects 6 to 12 years of age and with myopia -0.75 to -4.

Background: The aim was to assess the potential association between entrance pupil location relative to the coaxially sighted corneal light reflex (CSCLR) and the progression of myopia in children fitted with orthokeratology (OK) contact lenses. Additionally, whether coma aberration induced by decentration of the entrance pupil centre relative to the CSCLR, as well as following OK treatment, is correlated with the progression of myopia, was also investigated.

Methods: Twenty-nine subjects aged six to 12 years and with myopia of -0.

Objective: To assess refractive and biometric changes 1 week after discontinuation of lens wear in subjects who had been wearing orthokeratology (OK) contact lenses for 2 years.

Purpose: To examine which baseline measurements constitute predictive factors for axial length growth over 2 years in children wearing orthokeratology contact lenses (OK) and single-vision spectacles (SV).

Methods: Sixty-one children were prospectively assigned to wear either OK (n = 31) or SV (n = 30) for 2 years. The primary outcome measure (dependent variable) was axial length change at 2 years relative to baseline.

Purpose: To report 2 cases of keratopathy after uneventful cross-linking procedures for grade 3 keratoconus.

Methods: Two patients (21 and 11 years old) with grade 3 keratoconus underwent uneventful cross-linking in 1 eye. In both patients, multiple peripheral stromal precipitates, which extended centripetally, were observed 48 hours after the procedure.
