Effect of different incision phacoemulsification on corneal endothelial function and tear film function in senile cataract patients

Abstract

AIM: To explore the effect of different incision phacoemulsification on corneal endothelial function and tear film function in senile cataract(SC)patients. METHODS: Totally 90 SC patients(90 eyes)admitted to our hospital were randomly divided into the 2.2mm group(n=47, 47 eyes, 2.2mm corneal micro-incision phacoemulsification)and the 3.0mm group(n=43, 43 eyes, 3.0 mm clear corneal micro-incision phacoemulsification). The indexes of corneal endothelial function and tear film function were compared between the two groups before and after operation. RESULTS: There was no statistical difference on the average phacoemulsification time(APT), mean effective phacoemulsification time(EPT), average phacoemulsification energy(AVE)and preoperative and postoperative intraocular pressure between the two groups(P>0.05). There were statistical differences on the tear break-up time(BUT), basal tear secretion test(ST-Ⅱ), corneal sodium fluorescein staining(SCSF)score, corneal endothelial cell count, central corneal thickness and the variation coefficient of corneal endothelial cells between the two groups(PPPPPPPCONCLUSION: Phacoemulsification for SC patients can cause some damage in corneal endothelial function and tear film function, and 2.2mm corneal micro-incision have less damage and faster early recovery.
