Efficacy of different optical zone design with different myopia control for corneal refractive therapy (CRT): a one-year prospective cohort study
Clinical Scorecard: Effectiveness of Various Optical Zone Configurations in Myopia Management through Corneal Refractive Therapy: A One-Year Prospective Cohort Analysis
At a Glance
Category
Detail
Condition
Myopia
Key Mechanisms
Corneal refractive therapy (CRT) lenses with inverse geometric design to slow myopia progression.
Target Population
Children aged 7–12 years with myopia (SER ranging from −0.50 D to −6.00 D).
Care Setting
Optometry centres.
Key Highlights
200 children enrolled in the study.
CRT lenses worn overnight to achieve clear vision and slow myopia progression.
Small optical zones (5 mm, 5.5 mm) are more effective in suppressing axial length elongation.
Participants followed a strict wearing schedule of at least 8 hours per night.
Comprehensive evaluations included naked vision, ocular surface assessment, and corneal topography.
Guideline-Based Recommendations
Diagnosis
Myopia diagnosis confirmed by mydriasis optometry.
Management
Use of CRT lenses tailored to individual corneal morphology and visual demands.
Monitoring & Follow-up
Follow-up visits at one day, one week, one month, and every three months thereafter.
Risks
Exclusion of children with prior myopia control measures or other eye diseases.
Patient & Prescribing Data
Children aged 7–12 years with myopia.
CRT lenses fitted according to standardized guidelines to optimize therapeutic outcomes.
Clinical Best Practices
Perform comprehensive evaluations based on age, initial myopic refractive error, and corneal topography.
Ensure adherence to prescribed wearing schedule for optimal results.
Routine dilated examinations identified peripheral retinal abnormalities across refractive groups, with higher pathology rates among patients with at least 3.00 D of myopia
