Peripheral refraction
WebMultispectral refraction topography was used to quantify the defocus state of the retina in the 53° field of view and present the defocus form using a visual topographic map. Thus more accurate and reliable evidence was provided on the association between the peripheral retina and myopia development.

Web10. apr 2024 · Small incision lenticule extraction, which received FDA approval in 2016, is a safe and effective procedure that achieves a refractive change by creating a lenticule-shaped piece of tissue with the VisuMax femtosecond laser (Carl Zeiss Meditec) and then removing it from the cornea with forceps rather than making a flap and ablating tissue like … WebThe maintenance ratios of corneal refractive power changes at the peripheral points in the SMILE group were significantly higher than those in the LASIK group (p<0.05). Conclusion: Both groups achieved similar high efficacy and safety. SMILE surgery resulted in higher refractive power correction in the peripheral cornea than LASIK surgery.
WebPurpose: To establish whether axial growth and refractive error can be modulated in anisohyperopic children by imposing relative peripheral hyperopic defocus (RPHD) using multifocal soft contact lenses. Methods: This study is a prospective, controlled paired‐eye study with anisohyperopic children. Webon the peripheral cornea to a depth of 90-95% of the corneal thickness, leaving the clear central optical zone untouched (see Figure 3). These incisions weaken the cornea and allow intraocular pressure to push the peripheral cornea out, flattening the apex and reduc-ing its refractive power (2). Patients with RK nor-
WebPurpose: To evaluate changes in the peripheral refraction (PR), visual quality, and accommodative lag with a novel soft radial refractive gradient (SRRG) experimental contact lens that produces peripheral myopic defocus. Methods: 59 myopic right eyes were fitted with the lens. The PR was measured up to 30° in the nasal and temporal horizontal ...
