Significance of intraocular lens power calculation.

A total of 94 patients underwent extracapsular cataract extraction and insertion of Sinsky style two-loop posterior chamber intraocular lenses. Forty-six eyes received a standard power IOL and 48 eyes were given a preoperatively calculated IOL. A significant difference was found in the two groups with regard to the postoperative refractive error and uncorrected visual acuity.

Matrix formula for intraocular lens power calculation.

The matrix calculation was applied to Gaussian optics. Matrices were defined for a single diopter, a lens, an association of two centered systems having the same axis when the origins are taken at the vertices of the first and last refracting surfaces. The matrix formula then was used to calculate the power of the emmetropizing lens implant, and its results compared with the ones obtained by fi...

intraocular lens power calculation after keratorefractive surgery

purpose: to determine corneal power for intraocular lens (iol) power calculation in eyes with previous keratorefractive surgery. methods: in 13 eyes of 9 patients with previous keratorefractive surgery undergoing phacoemulcification, iol power was calculated using the clinical history method (chm) in one case, manual keratometry (mkr) in 2, simk in 3, and flattest k (topographically derived) in...

Accuracy of intraocular lens power calculation in paediatric cataract surgery.

AIMS To determine the accuracy of intraocular lens (IOL) power calculation in a group of pseudophakic children. METHODS A retrospective analysis of biometric and refractive data was performed on 52 eyes of 40 infants and children, who successfully underwent cataract extraction and IOL implantation. The following parameters were included: age at the time of surgery, keratometry, axial length, ...

The effect of testing distance on intraocular lens power calculation.

The calculation of the intraocular lens (IOL) power required for a specific patient typically uses a “lens constant” back-calculated from the refractive outcomes of earlier surgical results.1,2 An early recommendation was for clinicians to personalize their own lens constants to address systematic errors. However, the introduction of phacoemulsification equipment, continuous curvilinear capsulo...
