A 77-year-old man had cataract surgery in the left eye in March 2017. A toric intraocular lens (IOL) was implanted because of astigmatism. The postoperative meridian of the IOL was located nearly exactly in the planned meridian, which was controlled 1 week later with ray-tracing aberrometry (iTrace) and the smartphone application Axis Assistant. The referring ophthalmologist proceeded directly with a neodymium:YAG (Nd:YAG) laser posterior capsulotomy in his own office, after which the meridian of the implanted toric IOL was rotated more than 115 degrees. The rotation of the IOL was likely the result of a very early Nd:YAG treatment. Therefore, when a toric IOL is implanted it is important to wait at least 3 months after cataract surgery before proceeding with Nd:YAG to ensure complete rotational stability of the IOL.

Importance: After cataract surgery, postoperative residual astigmatism can influence a patient's visual quality and satisfaction. Finding ways to minimize this astigmatism is important.
Objective: To compare the clinical outcomes of femtosecond laser arcuate keratotomy (FSAK) and toric intraocular lens (TIOL) implantation for astigmatism correction in patients undergoing femtosecond laser-assisted cataract surgery.

Background: This study aims to comprehensively evaluate the predictive accuracy of six widely used toric intraocular lens (IOL) calculators in eyes undergoing cataract surgery with toric IOL implantation.
Methods: This retrospective study reviewed 53 eyes of 53 patients that underwent cataract extraction with toric IOL implantation using Zeiss 709 M. Six toric IOL calculators were evaluated: Barrett toric calculator (with predicted PCA, measured PCA, and TK), Kane formula (predicted PCA), and EVO 2.

Objective: Toric intraocular lens implantation has been used to correct corneal astigmatism during cataract surgery. The study aimed to compare the visual outcomes between manual vs markerless toric intraocular lens implantation in astigmatic correction.
Methods: The medical records of patients at American Eye Center who underwent phacoemulsification by multiple surgeons with insertion of monofocal or multifocal toric lenses via manual marking and markerless method from 2010-2019 were reviewed.

Background: The Eyhance Toric intraocular lens (IOL) builds upon the Tecnis Toric platform, initially associated with considerable post-operative rotational instability. Version 2, the Eyhance Toric IOL has been modified to enhance rotational stability. This study evaluates the post-operative rotational stability of the Eyhance Toric IOL compared to the Clareon Toric IOL, recognized for its stable performance.
