Cataract refractive phaco iol power calculation

AIM: To evaluate the accuracy of a practical method (the Actual K(a+p) method) of corneal power measurement for post-LASIK eyes undergoing cataract surgery. METHODS: Ten eyes of 7 patients (4 male, 3 female, average age 50.10±4.01 years, with -11.01±3.55D mean refraction before LASIK), underwent post-LASIK phaco+IOL cataract surgery. We used the posterior corneal curvature as measured by the Pentacam in a method we named Actual K(a+p) to calculate the post-LASIK corneal power for IOL calculation...

PURPOSE: To evaluate the efficacy, predictability, and safety of coaxial microincision phacoemulsification and toric intraocular lens (IOL) implantation in eyes with high corneal astigmatism. SETTING: Two eye clinics in Germany. DESIGN: Case series. METHODS: Routine cataract extraction using 2.2 mm coaxial phaco equipment and Acrysof toric IOL (3.00 to 6.00 diopters [D] cylinder) implantation were performed. Examinations included optical biometry, Haigis IOL calculation, topography, and objective and subjective refractions...

PURPOSE: To determine if the 1-month postoperative error of predicted refraction of the first eye can be used to alter intraocular lens (IOL) power selection and improve refractive results for the second eye in patients undergoing bilateral, sequential phacoemulsification with IOL implantation (phaco/IOL). DESIGN: Retrospective, consecutive, case series. PARTICIPANTS: Three hundred consecutive patients who underwent uncomplicated bilateral, sequential phaco/IOL between January 1, 2006, and December 31, 2007, by a single surgeon using a single IOL platform...
