Evaluating wavefront analysis application in intraocular lens placement

New advances in wavefront analysis offer an opportunity for greater refinement of cataract surgery. In this article, we critically review the recent advances in wavefront technology with specific attention to its application in customizing cataract surgery.

Historically, wavefront analysis has been implemented in corneal refractive procedures. Expansion of this technology may soon allow surgeons to choose the most optically appropriate intraocular lens for a patient's individualized wavefront pattern, thus allowing for a 'custom-fitted' intraocular lens. The benefit of full correction of all higher-order aberrations measured by wavefront analysis remains controversial. Additionally, in certain subsets of patients with specific anterior chamber pathology, wavefront intraocular lenses may not be appropriate.

The application of wavefront technology continues to expand the surgical options available to the practicing ophthalmologist. Significant advances have been made in our understanding of wavefront analysis and its usefulness in vision correction. Careful consideration of the optics of the whole eye must be considered when implementing wavefront analysis.
