1nthalmic Pty Ltd (D.T., J.D., K.E., D.F., C.F., F.C., R.C.B.), Sydney, Australia; University of New South Wales (D.T., K.E., D.F., C.F., F.C., R.C.B.), Sydney, Australia; Brighten Optix Corporation (R.W.), Taipei City, Taiwan; and Pacific University (R.W.), Forest Grove, OR.
Two new S.T.O.P. (Small Aperture Optics) contact lens designs, F2 and DT, showed visual performance comparable to MiSight. The F2 lens demonstrated superior subjective visual clarity and accommodative function in young myopic adults.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Myopia management in young adults is crucial.
- Novel contact lens designs aim to improve visual performance and binocular function.
- S.T.O.P. (Small Aperture Optics) designs offer a new approach to myopia control.
Purpose of the Study:
- To compare the visual performance and binocular/accommodative function of two novel S.T.O.P. contact lens designs (F2 and DT) against MiSight in myopic young adults.
- Evaluate subjective visual quality, visual acuity, binocular function, and accommodative responses.
- Assess the efficacy of new myopia control contact lenses.
Main Methods:
- Prospective, randomized, cross-over, single-masked study design.
- Participants wore F2, DT, and MiSight contact lenses daily for approximately 7 days each, with overnight peroxide disinfection.
- Visual performance assessed via subjective ratings, monocular/binocular high- and low-contrast visual acuity, heterophorias, accommodative facility, and accommodative response.
Main Results:
- F2 lenses received higher subjective ratings than MiSight for near and intermediate visual clarity and reduced ghosting.
- MiSight showed better monocular and binocular high-contrast visual acuity at distance and near compared to F2 and DT, with minimal differences.
- No significant differences were found in heterophoria between lens designs.
- F2 lenses demonstrated improved accommodative facility but a reduced accommodative response at near compared to MiSight.
Conclusions:
- The S.T.O.P. designs (F2 and DT) exhibit visual performance and binocular/accommodative functions comparable to MiSight.
- The F2 S.T.O.P. design offers advantages in subjective visual performance and monocular accommodative function.
- These findings suggest S.T.O.P. lenses are a viable alternative for myopia management in young adults.
