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.
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.
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.
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.
Achieving satisfaction for patients interested in a multifocal IOL begins with comprehensive preoperative screening and evaluation.
White light is comprised of different wavelengths of visible light, ranging from red (700 nm) to violet (400 nm). As white light passes through an optical system, each of its component wavelengths bends independently.
Ophthalmologists must be prepared to perform corneal refractive surgery enhancements after cataract surgery—and LASIK is often the optimal choice, according to Robert K. Maloney, MD.
A novel toric IOL features an aberration-free, transitional conic anterior optic surface shows pupil independence and improved tolerance to misalignment in bench testing and excellent clinical outcomes.
