Effects of different orthokeratology lens designs on slowing axial length elongation in children with myopia.

Aim: To elucidate whether differences exist in the impact on retarding the elongation of axial length (AL) among children with myopia when utilizing orthokeratology (ortho-k) lenses employing the corneal refractive therapy (CRT) design versus those employing the vision shaping treatment (VST) design.

Methods: This retrospective clinical trial aimed to collect and analyze AL data from individuals who wore ortho-k lenses for three years. A total of 654 subjects were enrolled and prescribed one of the three specific brands of ortho-k lenses: CRT, Euclid, and Mouldway.

Evaluation and application of a Chinese version symptom questionnaire for visual dysfunctions (CSQVD) in school-age children.

Objective: To develop and evaluate a Chinese version of the Symptom Questionnaire for Visual Dysfunctions (CSQVD) to quantify visual dysfunction symptoms in school-age children with various eye diseases, and to explore the relationship between ophthalmological disorders and visual dysfunction symptoms.

Methods: Following standard scale adaptation procedures, the Symptom Questionnaire for Visual Dysfunctions (SQVD) was translated into Chinese (CSQVD). We employed random sampling to survey 198 outpatients aged 7-18 to assess the psychometric properties of the CSQVD.

Repeatability and agreement of AOCT-1000 M, RTVue XR and IOL master 500 in measuring corneal thickness mapping and axial length applying principle of optical coherence tomography.

Purpose: To evaluate the repeatability and agreement of Fourier-domain optical coherence tomography (AOCT-1000 M and RTVue XR) and partial coherence interferometry biometer (IOL Master 500) in measuring corneal thickness mapping and axial length respectively.

Methods: Corneal thickness was measured by AOCT-1000 M and RTVue XR. Axial lengths were measured by AOCT-1000 M and IOL Master 500.

Lens regeneration using hESCs-derived cells -similar to natural lens.

Lens itself has limited regeneration functionality, thus we aimed to create regenerated lens with biological function to treat cataracts rather than the intraocular lens used in cataract surgery. We induced exogenous human embryonic stem cells to directionally differentiate into lens fate like cells , mixed these cells with hyaluronate, and then implanted the mixture into lens capsule to regenerate . We successfully achieved near-complete lens regeneration, and the thickness of the regenerated lens reached 85% of the contralateral eye, showing the characteristics of biconvex shape, transparency, and a thickness and diopter close to that of natural lenses.

Is Orthokeratology Treatment Zone Decentration Effective and Safe in Controlling Myopic Progression?

Objective: To compare the myopia control efficacy and safety of decentered versus centered positioning of orthokeratology.

Methods: This is a retrospective intrasubject study, including 46 children with myopia (25 boys, 21 girls; age 11.12±0.

A preliminary observation on rod cell photobiomodulation in treating diabetic macular edema.

Purpose: To evaluate the safety and effectiveness of photobiomodulation (PBM) in the treatment of diabetic macular edema (DME).

Methods: It was a single-center, self-controlled prospective study. The clinical records of 12 diabetic retinopathy patients (5 males and 7 females, 20 eyes in total) who were treated with PBM for DME at the Second Affiliated Hospital, Zhejiang University School of Medicine, were analyzed.

The safety of orthokeratology in myopic children and analysis of related factors.

Objective: To evaluate the safety of overnight orthokeratology (OK) wear and explore whether factors such as age, refraction and allergic conjunctivitis (AC) history were associated with corneal adverse events (AEs) incidence.

Methods: Medical records of consecutive patients who started OK for myopia correction and continued for more than one year were retrospectively reviewed. Clinical data including sex, baseline age, spherical equivalent refraction (SER), and related medical histories were retrieved.

Kayser-Fleischer ring with keratoconus: a coincidence? A case report.

Background: It is rare for hepatolenticular degeneration [Wilson's disease (WD)] to occur along with keratoconus (KC). In our report, a teenager was diagnosed with WD because of the discovery of Kayser-Fleischer (KF) ring in the cornea, and concomitant KC was found.

Case Presentation: A 19-year-old male was diagnosed with KC due to a rapid decline in visual acuity within a short period of time.

Is It Possible to Predict Progression of Childhood Myopia Using Short-Term Axial Change After Orthokeratology?

Objectives: To investigate changes in axial length in children undergoing orthokeratology (OK) and evaluate short-term axial change in predicting post-OK myopia progression.

Methods: In this retrospective study, the subjects included 70 myopic children aged 8 to 15 years wearing OK contact lenses for more than 3 years. Axial length changes at 0.

[Clinical comparison study of aspheric and spherical intraocular lenses].

Objective: To compare spherical aberration and visual quality in pseudophakic patients with a modified prolate aspheric intraocular lens (IOL) with patients with a spherical IOL.

Methods: A prospective study of 169 consecutive cases (169 eyes) was conducted. All cataract patients underwent phacoemulsification were randomized to receive an aspheric IOL or a spherical IOL.
