Rotational Stability of Monofocal and Trifocal Intraocular Toric Lenses With Identical Design and Material but Different Surface Treatment

Approximately 30% of patients undergoing cataract surgery have preoperative corneal astigmatism of 1.00 diopters (D) or higher.1,2 The presence of astigmatism compromises postoperative visual acuity, particularly when multifocal intraocular lenses (IOLs) are implanted, thus making the correction of astigmatism exceeding 1.00 D at the time of cataract surgery3 –6 crucial for meeting patient expectations of spectacle independence. Many methods exist for reducing preoperative corneal astigmatism during cataract surgery, including toric IOL implantation. Clinical studies have shown toric lenses
