Abstract:
AIM: To investigate the effects of different phacoemulsification incision for tear film stability in cataract patients.
METHODS: From January 2014 to September 2015, 108 patients (144 eyes) who underwent cataract surgery were divided into two groups: group A with clear corneal incision ( 52 cases with 74 eyes), group B with scleral tunnel incision (56 cases with 70 eye). Two groups of patients were taken the same incision width. Symptoms of dry eye and tear film break - up time ( BUT) were observed 1d before and 1d, 1, 3wk, 1 and 3mo postoperatively.
RESULTS:After performing cataract phacoemulsification 1d, 1wk, symptoms score of dry eye of group A was less than that of group B, the difference was statistically significant (t = -6. 199, -2. 871, P<0. 01), while at other times after operation there were no significant differences ( t = - 1. 639, - 0. 829, - 0. 301, P >0. 05); at postoperative 1d, 1 and 3wk, BUT of group B was better than those of group A, there were a statistically significant differences ( t = - 3. 718, -2. 342,-2. 506, P<0. 05), there were no significant differences at other the time after operation (t= -0. 882,1. 225, P>0. 05).CONCLUSION: The difference on effect of two different incision on the tear film stability only last a short time, which disappeared at 1mo after operation. The clear corneal incision has stronger impacts on tear film stability than scleral tunnel incision, while with a lower score on symptoms of dry eye.
