A prototype of a novel dual-mode, accommodating-disaccommodating intraocular lens with zonular capture haptics has been fabricated successfully. The lens has shown in bench studies to exhibit axial shift and shape change that results in up to about 26 D of accommodative change,
Steven Vold, MD, reports that toric IOLs provide an accurate, safe, and convenient way to correct astigmatism and uncorrected distance vision for glaucoma patients, while patients wanting presbyopic correction have IOL options to fit a range of visual needs.
The WhiteStar Signature Pro (J&J Vision) offers a diverse range of novel technologies that blend together to make cataract surgery easier, safer, and more efficient, according to Steven H. Dewey, MD.
The TECNIS Symfony IOL (J&J Vision) is breakthrough technology that is providing remarkable outcomes and driving a huge increase in the uptake of presbyopia-correcting IOLs among cataract surgery patients, according to Elizabeth Yeu, MD.
Patient selection is the key factor in obtaining the best visual outcomes after cataract surgery and intraocular lens implantation.
Because a variety of vision-limiting macular pathologies are detectable only with OCT, this imaging should be performed in all patients undergoing cataract surgery.
A new small-aperture intraocular lens (IOL) extends patients’ depth of focus as well as multifocal IOLs with fewer dysphotopsias, researchers say.
Scleral tunnel, “glued” fixation technique works better than alternative fixation techniques in cases where intraocular lenses (IOLs) cannot be placed in capsular bag or in the sulcus, according to Sumit Garg, MD.
When it comes to recommending a premium IOL, a patient’s glaucoma is only one factor to consider. Just like any other patient planning cataract surgery, visual needs and preferences for/against glasses are also important factors.
Residual astigmatism is not uncommon after toric IOL implantation. Depending on its cause and magnitude, lens reorientation may be a good solution.
Researchers conducted a 6-month study of patients implanted with the AcrySof IQ PanOptix presbyopia-correcting IOL to determine the binocular defocus curve of the lens. They concluded that these early results show good visual performance across the whole range of defocus. No unexpected adverse events were reported
In the past year, Matossian Eye Associates added a new category of presbyopia-correcting IOLs to the practice: the extended depth of focus (EDOF) IOL. The first IOL in this category is the Tecnis Symfony (Johnson & Johnson Vision). EDOF lenses from other manufacturers are in clinical trials, so it behooves the cataract surgeon to better understand how these lenses work.
When dealing with patients with retinal disease, macular disease, or a meaningful risk of retinal detachment, certain types of IOLs should be avoided due to potential complications.
Presbyopia patients have changed. They are younger than ever, more active than ever before, and they have more treatment options than ever before.
Implantation of a sulcus-supported, pseudophakic supplementary intraocular lens (IOL) can be a safe and effective method for improving vision in eyes with residual refractive error after cataract extraction, refractive lens exchange, or keratoplasty, said Thomas Kohnen, MD, PhD. It also can be used to provide reversible presbyopia correction.
The most common complication associated with the explantation of foldable intraocular lenses (IOLs) is lens dislocation or decentration. While glare and visual aberrations are the most common reasons for explanting multifocal lenses.
Cataract surgeons using toric intraocular lens (IOL) calculators are more likely to have better outcomes when using a centroid value for their surgically induced astigmatism (SIA), rather than a mean or a median value.
Staging patients based on their ocular pathologies using the most advanced diagnostic tools can result in excellent image quality by precisely establishing the need for lens- or corneal-based procedures.
There are a number of ways to improve near vision for presbyopes, including multifocal intraocular lenses (IOLs)–traditional or low add–and pseudoaccommodative IOLs. It has been well documented that a small pupil and higher order aberrations, such as spherical aberration (SA) or coma, can increase depth of focus.
Increased procedure volume and patient expectations have made IOL exchange procedures more common. Smaller incisions and the need to reduce trauma require new micro-instrumentation for best outcomes.
