Toric Iol Power Calculation
Obviously, toric lenses have to remain in stable positions after implantation bearing in mind that for every 10 degrees of misalignment, there is one third loss of toric correction. While some time ago this was still a problem, toric IOLs of today are significantly less affected by lens rotation. Another disturbing issue with toric lenses has also been fixed in the meantime: according to a new ...
متن کاملIOL Power Calculation after Corneal Refractive Surgery
PURPOSE To describe the different formulas that try to overcome the problem of calculating the intraocular lens (IOL) power in patients that underwent corneal refractive surgery (CRS). METHODS A Pubmed literature search review of all published articles, on keyword associated with IOL power calculation and corneal refractive surgery, as well as the reference lists of retrieved articles, was pe...
متن کاملComparison of Two Toric IOL Calculation Methods
Purpose To compare two calculators for toric intraocular lens (IOL) calculation and to evaluate the prediction of refractive outcome. Methods Sixty-four eyes of forty-five patients underwent cataract surgery followed by implantation of a toric intraocular lens (Zeiss Torbi 709 M) calculated by a standard industry calculator using front keratometry values. Prediction error, median absolute err...
متن کاملIOL power calculation after refractive surgery.
Cataract surgery is evolving more and more into a refractive procedure with high expectations in terms of visual rehabilitation. Especially patients presenting after previous Excimer laser corneal surgery are used to being independent from glasses. Unfortunately, some of these patients showed unexpected hyperopic surprises after cataract surgery in the past. The changes of corneal radii and ker...
متن کاملComparison of IOL--master and ultrasound biometry in preoperative intra ocular lens (IOL) power calculation.
Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included...
