Effect of micro - incision cataract phacoemulsification on ocular surface in type 2 diabetics / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM: To explore the effect of different corneal incision size on change in tear function after phacoemulsification cataract surgery in type 2 diabetics. ●METHODS:One hundred and fifty patients with type 2 diabetes (150 eyes) from Jan. 2015 to Oct. 2015 in our hospital were enrolled. The patients were randomly divided into two groups. Seventy-five patients (75 eyes) in group A coaxial 2. 2mm micro - incision phacoemulsification cataract extraction and intraocular lens (lOL) implantation; seventy-five patients (75 eyes) in group Bthe conventional coaxial 3. 0mm small incision phacoemulsification cataract extraction and lOL implantation. The difference of demographic characteristics between two groups were insignificant. The ocular surface disease index ( OSDl ) , corneal sensation, break up time (BUT) and Schirmer′sltest(Slt) were examined preoperatively and 1wk, 1, 3 and 6mo postoperatively. ●RESULTS:At 1wk, 1 and 3mo postoperatively, the OSDl score in two groups increased and the OSDl score of group B was significantly higher than those of group A and the differences were statistically significant ( all P0. 05). At 6mo postoperatively, the differences of OSDl score and corneal sensation in group B were statistically significant compared with preoperatively ( all P0. 05). ●CONCLUSION:Phacoemulsification surgery with 2. 2mm corneal micro-incision has less effect on change in tear function comparing to the 3. 0 mm incision control, which can be applied particularly in patients with type 2 diabetes.
