不同轴向的-0.25度柱镜对低度近视视觉质量的影响
The impact of different Axis-0.25D cylindrical lenses on visual quality in low-myopic eyes
摘要
Abstract
Objective:To explore the impact of different Axis-0.25D cylindrical lenses on visual quality in low-myopic eyes.Methods:A cross-sectional study was conducted,enrolling healthy young eyes(374 eyes)with-0.50 to-3.00 D myopia and different axis orientations of-0.25 D astigmatism.A repeated-measures design was used,with spherical and sphero-cylindrical corrections applied to obtain refractive prescriptions and best-corrected visual acuity(CDVA,logMAR)for each participant.The optical quality parameters of the two correction methods were measured using a double-pass optical quality analysis system(OQAS),including Objective Scattering Index(OSI),Modulation Transfer Function cutoff(MTF cutoff),Strehl Ratio(SR),and simulated contrast visual acuity-OQAS values(OV).The results were compared within each axis orientation(WTR,ATR,OBL).Results:In 374 participants(374 eyes),except for-0.25 D WTR astigmatism,both ATR and OBL astigmatism showed better CDVA with sphero-cylindrical correction(P＜0.05).For-0.25 D WTR astigmatism,all optical parameters showed no statistical differences(P＞0.05).For-0.25 D ATR astigmatism,sphero-cylindrical correction showed better results in all optical parameters except SR and 9％VA(P＜0.05).For-0.25 D OBL astigmatism,sphero-cylindrical correction showed better results in all optical parameters except OSI,SR,and 9％VA(P＜0.05).Conclusion:Low-myopic eyes with-0.25D ATR or OBL astigmatism can benefit from improved optical quality and visual acuity with cylindrical lens correction.关键词
