Clinical outcomes and surgeon assessment after implantation of a new diffractive multifocal toric intraocular lens.

Purpose: To evaluate the clinical outcome in eyes with significant corneal astigmatism after cataract surgery with implantation of a new diffractive multifocal toric intraocular lens (IOL).

Methods: Prospective, non-randomised multicentre clinical study including 57 eyes of 38 consecutive patients with an age between 37 and 84 years that underwent cataract surgery with implantation of the toric multifocal IOL Tecnis ZMT (Abbott Medical Optics, Santa Ana, California, USA). Changes in uncorrected and corrected logMAR distance, intermediate and near visual acuity ((uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), corrected near visual acuity) and manifest refraction were evaluated during a 2-4 month follow-up.

Intrastromal femtosecond laser surgical compensation of presbyopia with six intrastromal ring cuts: 3-year results.

Background/aims: To assess over a 36-month period functional results of the modified INTRACOR femtosecond laser-based intrastromal procedure to treat presbyopia.

Methods: 20 eyes of 20 presbyopic patients with mild hyperopia were included. The INTRACOR procedure with a modified pattern (six concentric intrastromal ring cuts) was performed using the FEMTEC femtosecond laser (Bausch+Lomb/Technolas Perfect Vision, Munich, Germany).

[Functional results after implantation of an aspheric, aberration-neutral intraocular lens].

Purpose: The aim of this study was to perform a clinical evaluation of the functional results and quality of vision after implantation of an aspheric, aberration-neutral, monofocal intraocular lens (IOL).

Patients And Methods: 47 eyes of 34 patients (median age: 68 years) with cataract were enrolled in this prospective clinical study that had Ethics Committee approval. The C-flex or Superflex aspheric IOL (Rayner, UK) was implanted after phacoemulsification.

[Clinical results after implantation of a new segmental refractive multifocal intraocular lens].

Background: The aim of the study was a clinical evaluation of an intraocular lens (IOL) with a segmental multifocal optic design and near addition of + 3.0 D as part of a CE approval study.

Patients And Methods: In a multicenter study the LENTIS Mplus LS-312 MF IOL (Oculentis) was implanted in 134 eyes of 79 patients with a mean age of 68 ± 12 years.

[Functional results after bilateral intrastromal femtosecond laser correction of presbyopia].

Purpose: The purpose of this study was to evaluate the results of bilateral intrastromal femtosecond laser correction of presbyopia (INTRACOR).

Methods: In a prospective study 17 patients were enrolled who had previously received binocular treatment in a two-step approach. Postoperative (4-8 months) outcomes were compared with a matched control group who had undergone only unilateral surgery of the non-dominant eye (n = 17 patients, 24 months after surgery).

[Intrastromal femtosecond laser-based presbyopia correction].

The surgical correction of presbyopia is gaining more and more popularity in the field of refractive surgery. Besides intraocular treatment with multifocal or accommodative intraocular lenses more and more corneal laser approaches are being established. These are performed either with the Excimer laser as laser in situ keratomileusis (LASIK) or the femtosecond laser.

[Localization and age relations of ocular aberrations].

Background: The aim of this study was to analyze the distribution of total, corneal, and mainly internal human third- to sixth-order aberrations (HOA) and investigate possible correlations between wavefront errors and patient age.

Patients And Methods: For this study 140 eyes of 140 subjects (age range 17-77 years) were measured three times each using Nidek Optical Path Difference scan. Mean value and standard deviation for each Zernike polynomial was computed for a 5-mm pupil diameter, and six different age groups were formed.

[Wavefront analysis in ophthalmologic diagnostics].

Modern aberrometry measures standard and so-called higher-order refractory aberrations. Ophthalmology and optometry use Zernike polynomials to describe aberrations of the retina and lens causing refractory errors. Aberrations of a higher order sometimes follow successful laser surgery, causing reduced vision and inducing patient dissatisfaction; enhanced wavefront data can help to avoid this.

[Scheimpflug and topography systems in ophthalmologic diagnostics].

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.

Precision of NIDEK OPD-scan measurements.

Purpose: To evaluate the repeatability of wavefront measurements using the NIDEK OPD-Scan.

Methods: A total of 179 eyes from 90 healthy volunteers (57 women and 33 men) with no corneal or lenticular pathology and normal visual acuity were enrolled in this study. Mean patient age was 39 years (range: 17 to 85 years).
