Comparative study on rotational stability of toric intraocular lenses in cataract patients with low astigmatism: vertical versus horizontal implantation.
OBJECTIVE To compare the effects of horizontal versus vertical in-the-bag implantation of toric intraocular lenses (IOLs) on postoperative rotational stability, refractive outcome, and vision-related quality of life in cataract patients with low regular astigmatism, and to identify risk factors for postoperative rotati...
