As previous studies indicated, diamond-like carbon (DLC) layers exhibit outstanding biocompatible properties. Additionally, due to high hardness and transmittance in infrared visible parts of spectra it is possible utilize for application ophthalmic optics. DLC are suitable coating spectacle lenses, contact lenses even intraocular lenses. In this paper, we focused on wear resistance different c...

PURPOSE To evaluate intraindividual visual acuity, wavefront errors and modulation transfer functions in patients implanted with two diffractive multifocal intraocular lenses. METHODS This prospective study examined 40 eyes of 20 cataract patients who underwent phacoemulsification and implantation of a spherical multifocal ReSTOR intraocular lens in one eye and an aspheric Tecnis ZM900 multif...

Experience is described of 150 cases in which an intraocular lens of the Binkhorst (iris clip and iridocapsular type) was introduced after cataract extraction. The most serious complications are dislocation and corneal dystrophy.

PURPOSE To evaluate a digital high-speed camera combined with digital morphometry software for dynamic measurements of phakic intraocular lens movements to observe kinetic influences, particularly in fast direction changes and at lateral end points. MATERIALS AND METHODS A high-speed camera taking 300 frames per second observed movements of eight iris-claw intraocular lenses and two angle-sup...

The present paper presents a review of multifocal intraocular lenses (IOLs) focusing on the optical principle used to create multifocality: refraction and diffraction. The principal optics of the different IOL designs in the market were discussed and compared. The main conclusion of this study states that diffractive bifocal optics seems to be superior to refractive designs which is well-substa...

Advancements in cataract surgery and intraocular lens (IOL) design have optimized the postoperative optical performance of the pseudophakic eye. One of the recent spotlights of IOL design has been formulating optical properties similar to a clear, young lens and addressing spherical aberration. Spherical aberration in the human eye is a combination of the positive spherical aberration of the co...

PURPOSE To compare the reliability and accuracy of intraocular pressure (IOP) measured while wearing soft contact lenses (SCLs) using a non-contact tonometer (NCT), Goldmann applanation tonometer (GAT), iCare rebound tonometer (RBT) and the Tono-Pen XL. METHODS Twenty-six healthy subjects were examined. The IOP was measured using NCT, GAT, RBT, and the Tono-Pen XL, while the subjects wore SCL...

PURPOSE OF REVIEW To review the methods described in the literature in the past year (from August 2003 to date). RECENT FINDINGS Techniques for scleral and iris suturing have proven safe and effective to fixate posterior chamber intraocular lenses and avoid the sight-threatening complications of anterior chamber lenses. SUMMARY Scleral and iris fixation have both become well-established eff...
