摘　　要：目的探讨巩膜切口与透明角膜切口对白内障超乳术后,手术源性散光(Surgically induced astigmatism, SIA)的影响。方法将73例拟行白内障超乳手术的患者随机分成二组:第一组采用3～5 mm的直线型巩膜切口 (I组);第二组采用3～4 mm的透明角膜切口(II组):分别观察术后1周、2周、1月、3月、6月二组病例的裸眼视力,SIA等情况。结果术后不同时期二组病例的裸眼视力≥0．5的百分比无显著性差异(P>0．05),而SIA则存在显著性差异(P<0．05)。结论 3～5 mm巩膜切口行白内障超乳手术,在早期可较透明角膜切口取得较好的屈光稳定性,同时增加了切口的安全性,从长远来看则无显著性差异。Objective： To investigate the effect on surgery induced astigamatism （SIA） in PHACO and implantation of IOL of scleral tunnel incision and corneal tunnel incision. Methods： Seventy- three cases were divided into two groups： the first group with 3 to 5 mm line scleral tunnel incision（Ⅰ） and the second group with 3 to 4 mm corneal tunnel incision （Ⅱ）. All the patients were performed PHACO and implantation of IOL. The uncorrected visual acuity and SIA were examined in one week, two weeks, one month, three months and six months after operation. Results： There was no significant difference in UCVA between two groups during periods after operation （ P 〉 0.05）, but there was significant difference in SIA （ P 〈 0.05 ）. Conclusions： The method of 3 to 5mm scleral incision in PHACO and implantation of IOL can increase the Safety of incision and the refraction is more stable than corneal tunnel incision in the early period after operation. There is no significant difference between two groups in the late period after operation.
