Management of Myopia in University Students With DIMS-TED Spectacle Lenses

Management of Myopia in University Students Using Defocus Incorporated Multiple Segment (DIMS) Spectacle Lenses.

The purpose of the study is to quantify the effectiveness of Hoya MiyoSmart IQ (DIMS-TED) spectacle lenses in slowing the rate of myopia progression in university students.

MiyoSmart spectacle lenses have been shown to be a safe and effective way of managing myopia progression in children aged 8-12 years. However, myopic progression is not limited to children of this age group and there is evidence that progression also occurs in university students. The researchers are therefore investigating the effectiveness of this intervention in a group of UK-based University students.

Inclusion Criteria:

• Myopic students studying at university
• Aged 18-23 years at the start of the study
• Show evidence of axial length growth of at least 0.06mm prior to entry into Stage 2 of the study.
• Have read the patient information sheet and be happy to sign the consent forms
• Be willing to adhere to the visit schedule and wearing times described in the protocol
• Agree to accept either the control or test lenses as assigned by the randomisation
• Have BCVA of +0.10 LogMAR or better in each eye

Exclusion Criteria:

• Previous myopia control use (optical or pharmacological)
• Amblyopia
• Myopic Rx up to -10D
• Astigmatism up to 4D
• Anisometropia <1.75D
• Binocular Vision anomalies (such as tropia)
• Taking medications that affect pupil size or accommodation
• A known allergy to tropicamide
