The Effect of Phacoemulsification and Extracapsular Cataract Extraction on the Eye Surface

Objective To evaluate the effect of phacoemulsification and extracapsular cataract extraction on the eye surface.Methods This clinical trial involved 156 patients(186 eyes) with cataract undergoing phacoemulsification(PHACO group,98cases114 eyes) or extracapsular cataract extraction(ECCE group,58cases 72 eyes).The symptoms and sings of dry eye disease,schirmers I test,break-up time(BUT),corneal fluorescein staining,rosebengal staining were tested and marked l months after operation,comparison for the results was made between two groups.Results The marks of all the index such as symptom,sings,diagnostic test between two groups had significant difference(P0.05).Marks in ECCE group were singificant higher than those in PHACO group.The rate of dry eye disease in the ECCE group(27.78%) was higher than that in the PHACO group(4.38%) and the difference was also singificant(P0.05).Conclusions In a short term postoperatively,the extracapsular cataract extraction seems more easily to effect the function of eye surface and lead to dry eye disease than phacoemulsification.
