BACKGROUND To report the diagnostic features and management strategy of a rare case of Weill-Marchesani syndrome with advanced glaucoma and corneal endothelial dysfunction. CASE PRESENTATION A patient presented with advanced glaucoma with an intraocular pressure of 49 mmHg in the left eye, and subsequently received trabeculectomy to control the intraocular pressure. Surprisingly, slit lamp ex...

We studied the spherical aberration of an intraocular lens, using third-order theory, ray tracing, and bench measurements by the Ronchi test. Good agreement was obtained for these three methods of investigation. In particular we found that the Ronchi test is an accurate method for quantifying this aberration.

BACKGROUND Posterior capsular opacification (PCO) is a common long-term complication of cataract surgery. Intraocular lens design and material have been implicated in influencing the development of PCO. This study evaluated the association of hydrophobic and hydrophilic intraocular lenses on preventing PCO. METHODS Medline, Cochrane, EMBASE, and Google Scholar databases were searched until Au...

The appearance of images through a multifocal intraocular lens (IOL) was simulated. The optical transfer function (OTF) of a model eye containing the multifocal lens was measured and divided by the OTF of the model eye with a monofocal IOL. This ratio was used to filter digital images, generating simulations that represent the retinal images seen through a multifocal intraocular lens when viewe...

Current Opinion in Ophthalmology 2008, 19:357–362 Purpose of review Corneal refractive procedures have become increasingly popular over the past decade allowing patients to have excellent uncorrected visual acuity and spectacle independence. As these individuals mature, many will eventually undergo cataract surgery. With the advances in modern cataract surgery and lens implant technology, parti...
