We present 2 cases of toric intraocular lens implantation for keratoconus: A 55-year-old man with forme fruste keratoconus with a preoperative uncorrected distance visual acuity (UDVA) of 20/800 and a refraction of -6.50-3.00x135 and a 46-year-old man with a claw-shaped topographic pattern, a family history of keratoconus, and a UDVA of 20/800 with a refraction of -5.00-3.00x85. The refraction had been stable for at least 5 years in both patients. Phacoemulsification and implantation of an acrylic toric IOL were uneventful. One year postoperatively, the UDVA was 20/25 in both cases, with a refraction of -0.25-0.50x140 and 0.25-0.50x60, respectively. No progression and no IOL rotation were observed. Toric IOLs may provide excellent outcomes in patients with stable and nonprogressive corneal ectasia.

Objective: To assess refractive and visual outcomes of a spherical Implantable Collamer Lens (ICL) followed by planned postoperative adjunctive laser-assisted in situ keratomileusis (LASIK) in the treatment of high compound hyperopic astigmatism.
Methods: In this prospective, multi-center, multi-surgeon, single-arm trial, eyes with ≥ 3.50 D hyperopia and ≥ 2.

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.
