lnfluence of lOL refractive index on straylight level following cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

Abstract?AlMTo investigate the influence of lOL refractive index ( Rl ) on measurement of straylight following cataract surgery.?METHODS:ln this case-control study, 77 eyes of 77 age-related cataract patients who underwent cataract phacoemulsification with posterior chamber aspherical arylic lOL implantation surgery in the Eye Hospital of China Medical University from Aug 2013 to Mar 2014, with a best corrected visual acuity ( BCVA) of 0. 5 or better, were classified into 3 groups randomly using 3 types of lOL Tecnis ZCB00 Group ( Rl = 1. 47, 22 eyes of 22 subjects); Hoya PY60AD Group ( Rl=1. 52, 24 eyes of 24 subjects);Alcon SN60WF or lQ Group ( Rl=1. 55, 31 eyes of 31 subjects ) . BCVA, pupil size, astigmatism, axial length, intraocular straylight were measured respectively.? RESULTS: Age, axial length, BCVA, pupil size, astigmatism of the three groups were not significant difference (P>0. 05). The straylight of Tecnis, Hoya, lQ group were 1.04±0. 15, 1. 19±0. 14, 1. 14±0. 18. Straylight levels had significant differences among three groups ( F=5. 352, P = 0. 007 0. 05).?CONCLUSlONPatients chosen the higher Rl lOL may have a higher straylight level after the surgery.
