Vectoranalysis of surgically induced astigmatism in small corneal and scleral cataract incisions.
Vector analysis of surgically induced astigmatism was performed on several scleral and corneal tunnel incisions (6.0-mm W; 3.5- and 2.5-mm L scleral tunnel; 4.1-mm linear and 2.5-mm L corneal tunnel). The analysis revealed a mean astigmatism between 1.18 and 0.64 D, as compared to 0.35 D in a control group of nonoperated eyes. The best results were obtained with the scleral and corneal L-shaped incisions.
