In a study published last year we showed the Barrett was the single most accurate IOL formula overall. Herein we report on the outcomes of new or updated formulas when run against the same datasets. Achievement of a target refractive outcome has become an integral part of cataract surgery. Fortunately, the advent of optical biometry and introduction of newer generation intraocular lens (IOL) calculation formulas has improved our ability to accurately predict cataract surgery refractive outcomes, as we showed in a study published in Ophthalmology last year. Since that report, several new or updated formulas have become available. We evaluated the latest formulas using the same dataset to determine whether they offer the potential for even more accurate prediction of refractive outcomes. The study was performed under a Kaiser Permanente IRB approval which did not require individual informed consent.

To evaluate refractive outcomes of cataract surgery in previously vitrectomized eyes and compare the accuracy of intraocular lens (IOL) calculation formulas in this population.
To analyze the precision of 6 intraocular lens (IOL) power calculation formulas in predicting refractive outcome in eyes with an axial length (AL) less than 22.0 mm.
To compare the accuracy of different intraocular lens (IOL) calculation formulas available on the American Society of Cataract and Refractive Surgery (ASCRS) post-refractive surgery IOL power calculat...
To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas available on the American Society of Cataract and Refractive Surgery calculator in calculating multifocal IOL po...
To investigate the effect of pupil dilation on ocular biometric parameters and intraocular lens (IOL) power calculation in schoolchildren using the Lenstar LS 900.
Implantation of an intraocular lens is the gold standard in modern day cataract surgery. The appropriate lens power needed to achieve the desired refractive outcome can be calculated with...
The aim of the study is to evaluate the degree of refractive error postoperatively in combined procedures and to calculate a new constant in order to improve current state of the art biome...
Pterygium is known to induce with-the-rule astigmatism. Excision of pterygium will steepen the cornea and reduce corneal astigmatism. We postulate that the alteration of keratometry readin...
The purpose of this study is to evaluate the safety and effectiveness of a new investigational modified light transmission monofocal intraocular lens compared to a conventional intraocular...
Multifocal intraocular lenses (MIOLs) provide enhanced far and near visual acuity, but they can bring about halos and glare, which are caused by design deficiencies of the IOLs. Compared t...
Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.
Lenses, generally made of plastic or silicone, that are implanted into the eye in front of the natural EYE LENS, by the IRIS, to improve VISION, OCULAR. These intraocular lenses are used to supplement the natural lens instead of replacing it.
Presence of an intraocular lens after cataract extraction.
The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.
Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
