Abstract:
Objective To compare efficacy of small incision cataract surgery whether combined with nucleus chopping or not in the treatment of cataract. Methods From March 2014 to September 2015,125 cases of age-related cataract(146 eyes) in the the First People′s Hospital of Xiantao were divided into 60 cases(75 eyes) of observation group and 65 cases(71 eyes) of control group by method of random sampling. The observation group accepted small incision cataract surgery combined with chopping nucleus. The control group only underwent small incision cataract surgery. The postoperative visual acuity,corneal astigmatism and operation time,and complications and so on in the two groups were compared. Results There was statistically significant difference in postoperative visual acuity after 1 week between the two groups(Z = -2. 078,P <0. 05),but there was no statistically significant difference in postoperative visual acuity after 1 month or 3 months between the two groups(Z= -0. 960,-0. 743,all P>0. 05). The postoperative corneal astigmatism after 1 week or 1 month between the observation group and the control group had statistically significant differences[(1. 33 ± 0. 45) D vs. (1. 52 ± 0. 49) D,(1. 03 ± 0. 42) D vs. (1. 18 ± 0. 44)D,t=2. 442,2. 108,all P<0. 05)],but there was no statistically significant difference in postoperative corneal astigmatism after 3 months between the two groups(t =0. 432,P >0. 05). There was no statistically significant difference in the operation time between the observation group and the control group[(11. 28 ± 2. 32) min vs. (11. 87 ± 2. 52)min,t=1. 473,P>0. 05]. One case of posterior capsular rupture occurred in the two groups,respec-tively. But serious complications such as lens nucleus escaped into vitreous cavity, explosive haemorrhage from the choroid or corneal endothelial decompensated had not been found. Conclusion The small incision cataract surgery combined with nucleus chopping has advantages in acquiring fast visual rehabilitation acuity in the early stage after operation,lower corneal astigmatism compared to that without nucleus chopping. Therefore,the small incision cataract surgery combined with nucleus chopping is worthy of clinical popularization and application.
