To Evaluate the Efficacy and Safety of Aspherical Soft Contact Lens in Myopia Control

January 19, 2020 updated by: APP Vision Care Inc.

A Prospective Randomized Control Study to Evaluate the Effect of Ticon Aspherical Daily Disposable Soft Contact Lens on Myopia Control

The objective of this study is to demonstrate that the Ticon Aspherical Daily Disposable Soft Contact Lens could retard myopia progress in youth

Detailed Description

This study is designed as a prospective, multicenter, randomized, double blinded, controlled, paired-eye comparison study. At least 60 evaluable subjects with myopia progression ≧ 0.75 D in the past 12 months will be recruited from 2 study sites. The experimental soft contact lens with aspherical design (Ticon Aspherical) will be randomly assigned to either the right eye or the left eye of the subject , then the fellow eye will be assigned a control lens with a single vision distance (SVD) soft contact lens (Ticon). Both lenses will be worn at least 8 hours a day, 5 days a week for 1 year. All lenses will be replaced every day. Brief assessment of the clinical findings will be followed up for one year at 1 day, 1 week, 1, 3, 6, 9, 12 months upon allocation. The primary efficacy outcome is change in spherical equivalent refraction (SER) measured by cycloplegic autorefraction over 12 months. The secondary outcome is change in axial eye length (AXL) measured over 12 months. The secondary outcome measure is used to corroborate any changes in SER

Description

Inclusion Criteria:

  • Myopia (SE) between -1.00D to -8.00D
  • Astigmatism less than or equal to 1.75D
  • Myopia progression ≧0.75 D in the past 12 months

  • Atropine/Pirenzepine treatment for myopia control in the past 1 month
  • Prior use of Ortho-K lenses
  • Dry eye with Schimer Test (basal secretion test) < 5mm/5min or other physical condition that would contraindicate contact lens wear

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ticon Aspherical Daily Disposable Soft Contact Lens
The subject will be requested to wear lens 8 hours a day, 5 days a week at least. The contact lens will be worn and replaced every day. All subjects will be followed for 1 year post device allocation with a brief clinical assessment at 1 day, 1 week, 1, 3, 6, 9, 12 months.
Placebo Comparator: Ticon Daily Soft Contact Lens
The subject will be requested to wear lens 8 hours a day, 5 days a week at least. The contact lens will be worn and replaced every day. All subjects will be followed for 1 year post device allocation with a brief clinical assessment at 1 day, 1 week, 1, 3, 6, 9, 12 months.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Spherical Equivalent Refraction (SER)
Time Frame: 12 months

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Primary safety Endpoints
Time Frame: 12 months
All dispensed eyes over all follow-up visits. Measured on a scale of 0-4 with 0=no findings and 4=severe findings. Epithelial edema, epithelial microcysts, corneal staining, limbal & bulbar injection, conjunctival abnormalities, corneal neovascularization and infiltrates will be measured.
