Update on Intraocular Lens Calculation Formulas.

Summary of "Update on Intraocular Lens Calculation Formulas."

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.

Effect of Pterygium Excision on Intraocular Lens Power Calculation for Subsequent Cataract Operation

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...

Neural Compensation, Visual Function and Visual Quality After Monofocal or Multifocal Intraocular Lens Implantation

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...

Medical and Biotech [MESH] Definitions

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.
