Abstract:
Objectivc To compare the accuracy and practicability of OPD-Scan Ⅲ marker methods and slit light narrow band marker methods in phacoemulsification and Toric IOL implantation.Methods A prospective randomized controlled study was conducted in 70 eyes of 70 patients with regular astigmatism (1.00-3.00 D).All patients underwent phacoemulsification and Toric IOL implantation and were randomly divided into two groups according to preoperative marker methods:observant group,in which OPD-Scan Ⅲ marker methods were used in 35 eyes of 35 patients,and control group,with application of slit light narrow band marker methods in 35 eyes of 35 patients.The postoperative visual acuity,residual astigmatism and deviation of lens axis (LAD) were observed and compared between the two groups.Results The uncorrected visual acuity (UCVA) between preoperative data and 3 months after surgery was statistically significant [(0.11 ± 0.09) vs.(0.59 ± 0.25)] (P =0.000).The difference in the postoperative 1 day and 3 months LAD was no statistically significant (P ＞ 0.05).The astigmatism between preoperation and 3 months after treatment was significant [(1.88 ± 0.49) D vs.(0.54 ± 0.30) D] (P =0.000).There was no significant difference in LAD between the two groups neither the first day nor 3 months after operation (both P =0.621).Conclusion OPD-Scan Ⅲ marker methods and slit light narrow band marker methods are both highly accurate and practical,but the former requires less for operator and is more easily accepted by patients.
