The INTRACOR procedure for presbyopia showed good visual acuity outcomes in the early postoperative period. The short treatment time in combination with maintained corneal integrity suggests this new technique has good potential for the treatment of presbyopia.

Stray light and subjective photopic phenomena do not show any basic correlation. Measurements in patients with refractive MIOLs showed less stray light than near segment or diffractive MIOLs. However, refractive MIOLs induced more halos compared to the other groups analyzed.

Modern Ophthalmology is currently experiencing a boom in anterior segment analysis tools that can increasingly gather information with one short measurement. These systems are based e.g. on so-called Scheimpflug (Pentacam, Galilei), slitlamp, and Placido technologies (Orbscan IIz) and other measurement systems. They help in analyzing the cornea in detail, including calculation of corneal wavefront. In addition, morphological and anatomical parameters such as anterior chamber depth, pachymetry, chamber angle, and lens densitometry can be analyzed. That makes these new technologies of interest for refractive surgery as well as for screening procedures such as Glaucoma, Keratoconus and others. This survey focuses on the two models, Oculus Pentacam and B&L Orbscan IIz as representative of all the other systems, as they are the most successful machines in this field.

Intraocular lens power calculation using modern standard formulas incorporated in a PCI biometry device after intrastromal femtosecond presbyopia treatment was reliable, with minimum underestimation on average.

We describe the analysis of accommodation using wavefront measurements in phakic and pseudophakic eyes. Accommodation measurements were performed in phakic and pseudophakic eyes using a dynamic stimulation aberrometry (DSA) device (Optana) as an attachment to the WASCA aberrometer (Carl Zeiss Meditec AG). Aberrations were measured for distance fixation (3.0 m) and near fixation (0.3 to 0.11 m) presenting different accommodative stimuli (3.0 to 9.0 diopters). The device was able to detect changes in aberrations using near and distance stimulation. Eyes with phakic iris-fixated intraocular lenses (IOLs) showed normal age-correlated accommodation. In pseudophakic eyes, accommodation varied depending on the IOL. With monofocal IOLs (eg, MA60AC, Alcon), there was no accommodation; with an accommodating IOL (eg, Synchrony, Visiogen), there was a low level of accommodation. The DSA device is capable of measuring accommodation using wavefront data. It will help to further analyze changes in accommodation-related wavefront aberrations.
