Abstract:
Objective To explore the effects of scleral electric coagulation(SEC) on postoperative astigmatism and incisional cicatrization after small-incision extracapsular cataract extraction (SIECCE).Methods 70 cataract patients who received SIECCE and intraocular lens implantation(IOLI) in our hospital were selected and randomly divided into the observation group and control group,35 cases in each group.The observation group received SEC,while the control group did not receive SEC.The postoperative corneal astigmatism of two groups was compared by using corneal topographic map meter,the postoperative anterior chamber reaction was observed through the slit lamp.Results 1 week after the surgery,the corneal astigmatism of the observation group and the control group were (0.88 ± 0.47) °,(1.24 ± 0.79) ° respectively,the corneal astigmatism of observation group was smaller than the control group(P ＜0.05).Postoperative 1 and 3 months,the corneal astigmatism of observation group and control group were (0.86 ± 0.54) ° vs (1.01 ± 0.69) °,(0.79 ± 0.28) ° vs (0.87 ± 0.49) °,there were no statistically significant differences between the two groups (t =1.14,1.86,all P ＞ 0.05).Postoperative shallow anterior chamber,leakage of anterior chamber of control group occurred 2 cases,3 cases,respectively,the incidence rate of complications was 14.28％.No postoperative complications occurred in observation group,the incidence rate of complications in the observation group (0.00％) was obviously lower than control group (x2 =13.83,P ＜ 0.01).Conclusion Application of SEC in SIECCE not only can strengthen stability of incision,reduce early postoperative corneal astigmatism,but also can promote healing of incision,prevent postoperative complications such as shallow anterior chamber and anterior chamber leaks.
