·AIM:To evaluate the imaging features of the macular after phacoemulsification cataract surgery by spectral-domain optical coherence tomography(SD-OCT).·METHODS:A retrospective series case study.46 eyes with simple age-related cataract who had phacoemulsification from Nov.2009 to Feb.2010 in our hospital without any complications during operation were included in this study.Visual acuity,slit-lamp examination and fundus were checked.SD-OCT(Topcon 3D-OCT-1000)was used to check retinal structure at 1 month after surgery.·RESULTS:Successful cataract surgery was performed in all eyes with postoperative best-corrected visual acuity(BCVA)improved.SD-OCT showed no significant change of the macular thickness except for slight increase of the central macular thickness,which was 217.34±36.15μm compared with195.87±40.87μm of normal people at the same age.There was no statistical difference between surgical group and normal people group.However,the slight abnormal at continuity of the IS/OS layer and integrity of the RPE layer appeared in some poor visual acuity and visual function recovery patients.·CONCLUSION:The macular thickness compared with normal people has no significant change after phacoemulsification in simple age-related cataract patients without other complication before surgery.Some patients at 1 month after surgery with slight poor visual acuity and visual function is probably due to the abnormal of continuity of the IS/OS layer and integrity of the RPE layer.·
