Toric intraocular lens in asymmetric astigmatism

International Ophthalmology, 2020
The aim of this study is to report our results of toric intraocular lens (IOL) implantation in patients with asymmetric astigmatism, its efficacy and safety in reducing the refractive cylinder.This is a retrospective cohort study. Patients with asymmetric astigmatism and non-progressive corneal ectasia, unable to fit hard contact lenses, with poor ...

Refractive Lens Exchange with Foldable Toric Intraocular Lens

American Journal of Ophthalmology, 2009
To assess visual and refractive outcomes, and rotational stability after refractive lens exchange (RLE) with toric intraocular lens (IOL) implantation to correct ametropia and preexisting astigmatism.Prospective, nonrandomized, observational case series (self-controlled).This prospective, nonrandomized, and self-controlled study included 32 eyes of 19 ...

Toric Intraocular Lens Calculations—Reply

Archives of Ophthalmology, 2012
[Extract] We thank Dr Simpson for pointing out the typographical error in our article.1 He is correct. The formula should have read E = F /[1 + (d /1.336) F]. All calculations in the article were done using this correct formula, and the formula in the article has been corrected.

Customized toric intraocular lens implantation in cornea plana

Journal of Cataract and Refractive Surgery, 2020
A 50-year-old woman with cornea plana had reduced visual acuity due to development of lenticular changes. Flat keratometry with high astigmatism, shallow anterior chamber depth, and short axial length made it challenging both for intraocular lens (IOL) power calculation and cataract surgery.

Laser-assisted marking for toric intraocular lens alignment

Journal of Cataract and Refractive Surgery, 2016
We describe a technique of 3-dimensional spectral-domain optical coherence tomography-controlled laser-assisted corneal marking for toric intraocular lens implantation. To facilitate accurate alignment, the technique creates 2 perpendicular intrastromal incisions (width 0.75 mm) using an image-guided femtosecond laser.

Results of higher power toric intraocular lens implantation

Journal of Cataract and Refractive Surgery, 2011
To evaluate the efficacy, predictability, and safety of coaxial microincision phacoemulsification and toric intraocular lens (IOL) implantation in eyes with high corneal astigmatism.Two eye clinics in Germany.Case series.Routine cataract extraction using 2.2 mm coaxial phaco equipment and Acrysof toric IOL (3.00 to 6.00 diopters [D] cylinder ...

Rescue technique for salvaging toric intraocular lens alignment

Journal of Cataract and Refractive Surgery, 2012
Accurate alignment of a toric intraocular lens (IOL) is a requisite to achieving the intended reduction in astigmatism at the time of cataract surgery. However, it requires a reasonably clear view of the limbal vascular anatomy, which is sometimes altered by chemosis from a subconjunctival anesthetic injection or a hemorrhage.
