Abstract

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.

韩国配戴非球面多焦点软性隐形眼镜的早期老花患者的球差变化。
研究目的本研究旨在评估配戴中心-近距离(CN)和中心-远距离(CD)多焦点隐形眼镜(MFCLs)对早期老花患者球差和视力的影响:50 名早期老花眼患者分别配戴 CN-MFCL 和 CD-MFCL 1 周。戴镜 1 周后,使用自动屈光仪测量球差:结果:使用这两种镜片时,总体视力无明显差异。结果:使用这两种镜片时,总体视力没有明显差异。参与者在远距离视力方面偏爱 CD-MFCL 镜片,在近距离视力方面偏爱 CN-MFCL 镜片。这项研究强调了基于年龄、屈光不正和个人反应的像差和满意度差异。正球面像差患者倾向于从 CN-MFCLs 中获益,因为它能改善远近视力,但要获得清晰的远距离视力还需要额外的矫正。早期老花眼患者在正像差普遍存在的情况下,一般更倾向于佩戴 CN-MFCLs 镜片,而负像差患者则对佩戴 CD-MFCLs 镜片时的远距离视力更满意:本研究证实,佩戴 MFCLs 会导致早期老花眼患者的球面像差和视力发生变化,尤其是在正像差普遍存在的情况下。未来的研究应针对不同阶段的老花眼调查这些影响。

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.
