S.T.O.P.® Technology Contact Lenses Versus Dual-focus Contact Lenses for Slowing Down Myopia Progression in Children

Inclusion Criteria:

• Be between 8-14.

• Have:

• Read the Informed Assent.

• Been explained the Informed Assent.

• Indicated an understanding of the Informed Assent.

• Signed the Informed Assent.

• Have their parent / legal guardian:

• Read the Informed Consent.

• Been explained the Informed Consent.

• Indicated an understanding of the Informed Consent.

• Signed the Informed Consent.

• Along with their parent / legal guardian, be capable of comprehending the nature ofthe study, and be willing and able to adhere to study requirements.

• Along with their parent / legal guardian, agree to maintain the visit schedule .

• Agree to wear allocated contact lenses for a minimum of 5 days per week, at least 6hours per day on days lenses are worn but not > 16 hours per day, and to removelenses at night (i.e., daily wear only with no contact lens wear during sleep), fortheir duration of the study and to inform the investigator if their schedule isinterrupted. Wearing time can be modified by the investigator for health reasons.

• Possess wearable and visually functioning spectacles.

• Be in good general health, based on the parent's / legal guardian's knowledge.

• Have best-corrected high contrast visual acuity based on manifest refraction of 0.10logMAR (20/25, 6/7.6) or better in each eye.

• Meet the following criteria determined by cycloplegic autorefraction:

• Spherical equivalent between -0.75 to -4.00 D inclusive.

• Astigmatism ≥ -1.00 D. *participants who fail astigmatism criterion with autorefraction passastigmatism criterion if ≥ -0.75 D is measured with subjective refraction.

• anisometropia ≤ 1.00 D.

Exclusion Criteria:

• Participant is currently, or within 30 days prior to this study, has been an activeparticipant in another study.

• Current or prior use of ANY form of myopia control, including but not limited to:

• Optical devices.

• Bifocal / multifocal spectacles of any type.

• Bifocal / multifocal contact lenses of any type.

• Orthokeratology of any type.

• Pharmacological agents.

• European and Indian sites: Atropine.

• Chinese sites: Atropine with a concentration > 0.01%. Participants whohave previously used 0.01% atropine are eligible for this study providedthey agree not to use 0.01% atropine for at least 30 days before baselineand at any time during the study.

• Pirenzepine.

• Participant born earlier than 30 weeks or weighed < 1500 g at birth.

• Habitual use of a systemic or topical medication that may alter normal ocularfindings / is known to affect a participant's ocular health / physiology or contactlens performance either in an adverse or beneficial manner at enrolment and / orduring the clinical trial.

• A known allergy to sodium fluorescein, benoxinate, proparacaine, or tropicamide.

• Chinese sites: A known allergy to cyclopentolate.

• A known corneal hypoesthesia (reduced corneal sensitivity), corneal ulcer, cornealinfiltrates, ocular viral or fungal infections, or any other recurrent ocularinfections.

• Strabismus by cover test at distance (3 m) or near (40 cm) while wearing distancecorrection under non-cycloplegic conditions.

• Known ocular or systemic disease, such as but not limited to:

• Diabetes.

• Graves' disease.

• Glaucoma.

• Uveitis.

• Scleritis.

• Auto-immune diseases such as ankylosing spondylitis, multiple sclerosis,Sjogrens syndrome, and systemic lupus erythematosus.

• Any ocular, systemic, or neuro-developmental conditions that could influencerefractive development, such as but not limited to:

• Persistent pupillary membrane.

• Vitreous haemorrhage.

• Cataract.

• Central corneal scarring.

• Eyelid haemangiomas.

• Marfan's syndrome.

• Down's syndrome.

• Ehler's-Danlos syndrome.

• Stickler's syndrome.

• Ocular albinism.

• Retinopathy of prematurity.

• Keratoconus or irregular cornea.

• Biomicroscopic that contraindicate contact lens, such as but limited to:

• Neovascularisation or ghost vessels ≥ 1.5 mm in from limbus.

• Any active anterior segment disease that contraindicates safe contact lenswear.

• Clinically significant giant papillary conjunctivitis.

• Clinically significant abnormalities of the anterior segment, lids,conjunctiva, sclera, or associated structures.

• Allergic or seasonal conjunctivitis if the investigator believes it couldsignificantly interfere with maintaining a specified wearing schedule.

• The investigator may, at their discretion, exclude anyone who they believe may notbe able to fulfil the clinical trial requirements or it is believed to be in theparticipant's best interests.
