BCDVA = best-corrected distance visual acuity; SE = spherical equivalent

*The change in refractive astigmatism was statistically significant due to the lens implantation (SA60T3 p = 0.04; SA60T4 p < 0.001; SA60T5 p < 0.001).

The corneal astigmatism did not change significantly due to the surgery (SA60T3 p = 0.17; SA60T4 p = 0.98; SA60T5 p = 0.26).
