purpose: to assess hoffer correction factor in measurement of axial length (al) in eyes with phakic iol implants. methods: in this descriptive historical cohort study, axial length was measured by ultrasound (us) and iol master in both phakic and pseudophakic modes in 24 eyes of 14 patients with artisan intraocular lenses (iols) implanted for refractive purposes, hoffer’s suggested formula for ...

BACKGROUND To evaluate how differences in ocular biometry affects the Hoffer Q, Holladay 1, SRK/T, and Haigis intraocular lens power calculation formulae predictions. METHODS This study was performed on 91 eyes of 91 patients who underwent uneventful cataract surgery. Ocular biometry values were measured using the IOL Master 500, and intraocular lens (IOL) power was calculated using the Haigi...

Purpose To compare the performance of OKULIX ray-tracing software with SRK-T and Hoffer Q formula in intraocular lens (IOL) power calculation in patients presenting with cataract. Methods In this prospective study, 104 eyes of 104 patients with cataract who underwent phacoemulsification and IOL implantation were recruited. Three IOL brands were used and for all eyes, IOL power calculation was...

INTRODUCTION Selection of an appropriately-powered IOL is a complex issue, especially in eyes with an axial length of less than 20 mm in pediatric cataract. OBJECTIVE To assess the accuracy of IOL power calculation formulae in pediatric cataracts in eyes with an axial length of less than 20 mm. MATERIALS AND METHODS The records of children less than 15 years old with congenital cataract who...

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),...

BACKGROUND To compare refractive index variation between Hoffer-Q, Haigis and SRK/T formulas used for preoperative biometry calculation in patients with axial length >25 mm, undergoing cataract surgery. MATERIALS AND METHODS This is a randomized clinical trial study was performed on 54 eyes of 54 patients with ages of 40-70 years old and axial length >25 mm classified into three groups that t...
