In this technique, I/A of cortex as a separate step can be omitted, thereby eliminating that portion of the surgical procedure in which posterior capsular disruption most frequently occurs. Residual cortical cleanup is accomplished in the presence of a posterior chamber IOL which protects the poserior capsule by holding it remote from the aspiration port.

We describe a first-and-second-diffractive-order intraocular lens ((1st,2nd)DIOL) within the class of hybrid refractive-diffractive designs for intraocular lenses (IOLs) and analyse its properties of focus extension and compensation of longitudinal chromatic aberration (LCA), particularly for lenses with low addition. Power, energy efficiency and their wavelength dependence are extended from mo...

PURPOSE To analyze the accuracy of the Holladay 2 formula, which has been proposed as an improvement over the original Holladay formula. METHODS This retrospective analysis comprised 317 eyes operated on by 1 surgeon using 1 technique and 1 intraocular lens style in a specialty practice. Because the Holladay 2 formula has yet to be published, its accuracy can only be analyzed using the commer...

We present a technique for suture fixation of an intraocular lens (IOL) in the absence of capsule support. This technique is useful for the treatment of aphakia and the management of IOL complications or cataract surgery when all capsule support is lost.

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...

We hereby describe the correct method to perform a "handshake technique" and easy transfer of haptics from one hand to another for glued intrascleral fixation of an intraocular lens (glued IOL). The procedure was implemented in 57 cases that necessitated the application of performing a glued IOL procedure and it resulted in an appropriate and easy externalization of haptic in all the cases. The...
