PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation methods for post-myopic excimer laser surgery patients without previous refractive surgery data using the Holladay IOL Consultant Program and the American Society of Cataract and Refractive Surgery (ASCRS) IOL Power Calculator. SETTING Wang Vision Cataract and LASIK Center, Nashville, Tennessee, USA. DESIGN Case ser...

PURPOSE To investigate the effect of anterior chamber depth (ACD) on the refractive outcomes of the SRK/T, Holladay 1, Hoffer Q and Haigis formulae in short, normal, long and extremely long eyes. METHODS This retrospective study involved patients who had uncomplicated cataract surgery. Preoperative axial length (AL) was divided into four subgroups: short (< 22.00 mm), normal (22.00-24.49 mm),...

OBJECTIVE To assess intraocular lens (IOL) power calculations in patients undergoing cataract surgery after excimer laser photorefractive keratectomy (PRK) for myopia. METHODS Four eyes of two patients underwent phacoemulsification with IOL implantation after PRK for myopia. The estimated refractive error that would have been induced had the IOL predicted for emmetropia been implanted was cal...

Introduction: This study aimed to evaluate the differences in Intraocular Lens (IOL) power keratoconus (KC) eyes between calculations obtained clinically with most commonly used formulas healthy (SRK T, Holladay 1, Hoffer Q and Haigis) as well define predictive factors for such differences. Methods: retrospective comprised 43 of 22 patients no previous ocular surgery. IOL powers were calculated...

BACKGROUND The study presented here aims to optimize the accuracy of intraocular lens (IOL) power calculations in patients after DMEK by evaluation of the impact of the altered anterior/posterior corneal curvature relationship. METHODS Scheimpflug-based Oculus Pentacam imaging was performed after DMEK surgery for Fuchs endothelial dystrophy. The IOL power was calculated for all patients by ra...

PURPOSE To prospectively evaluate the no-history method for intraocular lens (IOL) power calculation in 15 cataractous eyes that had previous myopic laser in situ keratomileusis (LASIK) and for which the pre-LASIK K-readings were not available. SETTING Private practice, Lynwood, California, USA. METHODS The predicted IOL power was calculated in each case. Also calculated were the mean arith...

By Noel Alpins, FRANZCO, FRCOphth, FACS The ASSORT Toric Calculator offers unique features, designed for accuracy and functionality, that are not available on other calculators provided by implant companies or private groups. Its primary unique feature is the ability to calculate the most effective implant (sphere and toricity) available from all companies worldwide and compare IOLs based on th...
