Because the not too long ago printed article within the journal Open Ophthalmology Journal reveals, there are vital variations among the many measures of corneal parameters obtained by the three mostly used ophthalmic gadgets, referred to as topographers.
It is a crucial difficulty for docs in search of to attain one of the best affected person outcomes for eyesight restoration after cataract surgical procedure.
The calculation of the astigmatic energy required for the intraocular lens (IOL) that’s to be implanted after cataract surgical procedure relies on the magnitude and axis of corneal astigmatism thought of, which may be measured and calculated utilizing totally different topographers.
The accuracy when calculating the suitable IOL determines the amount and high quality of imaginative and prescient of the post-operative cataract sufferers and in addition defines their want for spectacles after the surgical procedure.
This work, printed by a group of ophthalmologists from Spain compares the measures obtained from Pentacam system (Oculus Optikgera?te GmbH, Wetzlar, Germany), Cassini (i-Optics, The Hague, The Netherlands, distributed by Ophtec) and IOL-master 700 system (Carl Zeiss Meditec AG, Jena, Germany). These three gadgets measure corneal parameters utilizing totally different applied sciences.
The possible comparative research critiques information from 94 eyes from 53 sufferers ranging in age from 29 to 77 years outdated, recruited from the anterior phase session at Vithas Eurocanarias Instituto Oftalmológico in Las Palmas de Gran Canaria (Spain).
Customary and whole keratometric readings and astigmatism measures obtained with these gadgets can’t be used interchangeably, as there are statistically vital and clinically related variations among the many outcomes obtained.”

“Due to this fact, if the info of those three methods are used for toric IOL energy calculations, vital variations may be anticipated, what is going to have an effect on the post-op imaginative and prescient within the cataract sufferers?” The authors advocate that refractive predictability research maintain the reply to this query, and this must be investigated additional for every sort of optometric system.
