Objective To observe the effect of cataract phacoemulsification combined with intraocular lens implantation on retina and choroidal thickness in fundus macular central fovea.Methods Sixty-two cataract patients(101 eyes) with cataract phacoemulsification combined with intraocular lens implantationn in the Zhengzhou Municipal Second People′s Hospital from January 2014 to January 2016 were selected.The retinal thickness of fundus macular central fovea and choroidal thickness under macular central fovea by the optical coherence tomography were recorded and compared among preoperative 1 d,postoperative 1 d,postoperative 1 week,postoperative 1,3,6 months.The correlation between the retinal thickness and choroidal thickness with the age and optical axial as well as the correlation between postoperative choroidal thickness change and related indexes were analyzed.Results The preoperative retinal thickness had no relationship with the age and optical axial length of the patients(r=0.061,0.046,P >0.05);the preoperative choroidal thickness under macular central fovea was negatively correlated with the age and the optical axial length of the patients(r=-0.821,-0.912,P<0.05);the retinal thickness of macular central fovea on postopera tive 1 d,1 week,1,3,6 months were(225.9±22.6),(226.6±21.9),(232.4±19.5),(227.0±19.4),(225.8±17.2)μm respectively,in which the retinal thickness at postoperative 1 month was significantly higher than that before operation,the difference was statistically significant(P<0.05);the choroidal thickness on postoperative 1 d,at postoperative 1 week,1,3,6 months were(263.8±52.1),(267.5±49.9),(270.4±51.7),(269.7±53.2),(260.5±47.8) μm respectively,in which the choroidal thickness at postoperative1 week,1,3 months were significantly higher than that before operation,the difference was statistically significant(P <0.05).The choroidal thickening change at postoperative 1,3 months had a negative correlation with the optical axial length(r=-0.812,-0.805,P<0.05) and a positive correlation with preoperational choroidal thickness(r=0.751,0.792,P<0.05),while had no correlation with the age,preoperative retinal thickness and retinal thickening change(P>0.05).Conclusion The choroidal thickness under macular central fovea has negative correlation with the age and optical axial length.After the cataract phacoemul-sification combined with intraocular lens implantation,the retinal thickness and the choroidal thickness in the macular central fovea are increased.The persistent period of choroidal thickness increase is longer and the increase is more significant.The change of choroid thickness is negatively correlated with the optical axial length and positively correlated with preoperative choroidal thickness.
