Keratometry-A Scan and Prediction of IOL Lens Power in Felines Das Arup*, Ramani C., Md.

Online published on 26 July, 2017. Abstract Intraocular lens (IOL) implantation is the only effective treatment to restore the vision of a cataract eye. The incidences of cataract in domestic short haired cats are increasing day by day. Fourteen eyes from seven clinically normal cats were examined for intraocular distances (using A-scan ultrasound biometry) and corneal curvature (using keratometry) and by using these data appropriate posterior chamber IOL strength to achieve emmetropia after lens removal has been predicted. Three theoretical formulas were used to calculate the diopteric strength of IOL. The overall average predicted IOL power of all the eyes were 52.68 ± 2.23D. The calculated mean IOL power in cats was more than the power required in dogs. Top Keywords Cat, IOL, strength. Top | |
