Abstract

We evaluated postoperative changes of astigmatism and uncorrected visual acuity in 5.5 mm unsutured scleral tunnel incision, phacoemulsification and oval shape intraocular lens(IOL) implantation. Average surgically induced astigmatic changes were 0.09D against the rule(-0.09D) at one week, -0.25D at one month, -0.28D at two months in 55 patients as well as -0.21D at six months(n=25) and -0.38D over one year(n=25). The average uncorrected visual acuities improved from 0.07 preoperatively to 0.67 at one week, 0.75 at one month, 0.75 at two months in 48 patients as well as 0.72 at six months(n=25) and 0.64 over one year(n=25) postoperatively. There were no statistic~lly significant changes from one week over one year in both variables(p>0.05). Our results suggest that change of surgically induced astigmatism is little and stable as a well as rehabilitation of postoperative visual acuity is rapid in cataract operation using the 5.5 mm unsutured scleral tunnel technique.
