How to calculate toric intraocular lenses in clinical practice?

Toric Intraocular Lenses in Cataract Surgery

In modern cataract surgery, spectacle freedom is becoming more and more important. Emmetropia can be achieved for patients with myopic or hyperopic refractive errors by selecting the appropriate spherical lens power. However, approximately 20% of patients who undergo cataract surgery have 1.25 diopters (D) of corneal astigmatism or more. (FerrerBlasco, Montes-Mico et al. 2009; Hoffmann and Hutz...

How safe are intraocular lenses?

Repositioning technique and rate for toric intraocular lenses.

I previously reported the excellent rotational stability of the AcrySof toric intraocular lens (IOL) (Alcon, Inc.) in a consecutive series of my first 100 cases. Ninety percent and 99% of the IOLs were aligned within 5 degrees and 10 degrees of the intended axis, respectively, and no IOL required surgical repositioning. I compared the results in this series with those in my retrospective series...

Surgical management of astigmatism with toric intraocular lenses.

Correction of corneal astigmatism is a key element of cataract surgery, since post-surgical residual astigmatism can compromise the patient's uncorrected visual acuity. Toric intraocular lenses (IOLs) compensate for corneal astigmatism at the time of surgery, correcting ocular astigmatism. They are a predictable treatment. However, accurate measurement of corneal astigmatism is mandatory for ch...

Results of the AcrySof Toric intraocular lenses implantation

BACKGROUND The expectations of post-removal cataract surgery patients are extremely high, and best vision acuity is expected. The best refractive results are influenced by two factors - cataract surgical removal and the corneal astigmatism correction. Currently, the two most often applied corneal astigmatism removal methods are laser surgery and toric intraocular lens implantation, with the lat...
