Spherical Aberration Changes in Patients With Early Presbyopia Wearing Aspheric Multifocal Soft Contact Lenses in South Korea.
Objectives: The aim of this study was to evaluate the impact of wearing center-near (CN) and center-distance (CD) multifocal contact lenses (MFCLs) on spherical aberrations and visual acuity in patients with early presbyopia.
Methods: Fifty participants with early presbyopia wore CN-MFCLs and CD-MFCLs for 1 week. The average corrected refractive power was -2.65±1.67 D. Spherical aberration was measured using an auto-refractor after 1 week of lens use.
Results: No significant difference in overall visual acuity was observed when using either lens. Participants favored CD-MFCLs for distance vision and CN-MFCLs for near vision. This study highlighted variations in aberration and satisfaction based on age, refractive errors, and individual responses. Patients with positive spherical aberrations tended to benefit from CN-MFCLs, which improved both distance and near vision, although additional correction was required for clear distance vision. Patients with early presbyopia generally preferred CN-MFCLs when positive aberration was prevalent, whereas those with negative aberration reported greater satisfaction with distance vision when wearing CD-MFCLs.
Conclusions: This study confirmed that wearing MFCLs leads to changes in spherical aberration and visual acuity in patients with early presbyopia, particularly when positive aberration prevails. Future research should investigate these effects across different stages of presbyopia.
期刊介绍:
Eye & Contact Lens: Science and Clinical Practice is the official journal of the Contact Lens Association of Ophthalmologists (CLAO), an international educational association for anterior segment research and clinical practice of interest to ophthalmologists, optometrists, and other vision care providers and researchers. Focusing especially on contact lenses, it also covers dry eye disease, MGD, infections, toxicity of drops and contact lens care solutions, topography, cornea surgery and post-operative care, optics, refractive surgery and corneal stability (eg, UV cross-linking). Peer-reviewed and published six times annually, it is a highly respected scientific journal in its field.
