Prototype soft CLs designed to replicate the optical profile induced by OK were found to provide similar whole eye wavefront aberration measurements at distance and near fixation to existing OK lens wearers.
Soft contact lenses designed to simulate the change in refraction optical pro-file from orthokeratology (OK) fail to slow axial eye elongation or change to refrac-tion over 1-year of wear in children, leading to suggestion that OK’s propensity to slow myopia progression may not be due to changes OK makes to optical profile.
In myopia development the sclera is at risk of deformation due to increasing axial length progression. This research investigates whether cross-linking treatment could be used to stiffen the sclera as a way to restrict axial eye elongation.
This research showed that centre near design multifocal CL’s do not appear to reduce visual acuity at near in young accommodating myopes, but result in a slight reduction in visual acuity at distance.
This research investigated orthokeratology lenses designed for a higher peripheral ‘add’ power, and how these influenced corneal hysteresis (rigidity) and higher order aberrations.
This study showed that multifocal contact lens wear in young adult myopes increases accomodative lag, and utilized auditory biofeedback training to improve it. The results and implications are discussed here.
