Abstract:
Objective:To explore the effect of phacoemulsification through corneoscleral incision on cataract patients with type 2 diabetes mellitus.Methods:A prospective case-control study was conducted to collect cataract patients with type 2 diabetes who were admitted to the First Hospital of Hebei Medical University from January 2018 to June 2019. All patients were treated with phacoemulsification. They were randomly divided into three groups: 40 cases (68 eyes) of corneoscleral incision, 40 cases (66 eyes) of upper transparent corneal incision and 40 cases (70 eyes) of temporal transparent corneal incision. The dry eye symptom scale score, corneal fluorescein staining (FL) score, tear rupture time (BUT) and Schirmer I test (SIt) were compared in three groups; The levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) in aqueous humor were compared among the three groups before and 7 days after operation.Results:⑴ The levels of IL-6 and IL-8 in aqueous humor of the three groups were significantly lower than those before operation, especially in group A ( P<0.05), but there was no significant difference in the levels of IL-6 and IL-8 in aqueous humor of group B and C ( P>0.05); ⑵ The scores of dry eye symptoms in group B were significantly higher than those in group A at 1 and 7 days after operation ( P<0.05); The scores of dry eye symptoms in group C were significantly higher than those in group A and B at 1, 7 and 30 days after operation ( P<0.05); The dry eye symptom score in group A and B decreased to the preoperative level 30 days after operation ( P>0.05), and that in group C decreased to the preoperative level 90 days after operation ( P>0.05); ⑶ The postoperative 1, 7 and 30 d BUT in group A and C were significantly higher than those in group B ( P<0.05), and the level of SIt was significantly lower than that in group B ( P<0.05); At 1 and 7 days after operation, SIt in group A was significantly lower than that in group C ( P<0.05); the FLS score in group A and C was significantly lower than that in group B at 1 and 7 days after operation ( P<0.05). Conclusions:The incision of corneoscleral margin has little effect on tear film stability and ocular surface function of cataract patients with type 2 diabetes mellitus treated by phacoemulsification, which is worthy of clinical recommendation.
