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 (P<0. 05). At 1wk and 1mo after operation, the BUT in the two groups was significantly lower than that before operation (P<0. 05) while the ST-Ⅱ was significantly higher than that before operation ( P< 0. 05), and the SCSF first increased and then decreased (P < 0. 05 ), and corneal endothelial cell count was significantly lower than that before operation (P<0. 05), and the central corneal thickness and the variation coefficient of corneal endothelial cells significantly increased (P<0. 05). The changed degrees of BUT, ST-Ⅱ, SCSF score, corneal endothelial cell count, central corneal thickness and corneal endothelial cell variation coefficient in the 2. 2mm group were less than those in the 3. 0mm group (P<0. 05). ·CONCLUSION: 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.
