Role of dysfunctional lens in refractive lens exchangeStaging 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.
Centroid value, posterior cornea info adds game for toric calculatorsCataract 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.
Micro-instrumentation reduces trauma in IOL exchangeIncreased 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.
New IOL category offers more natural range of visionThere 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.
Formula for achieving successful multifocal IOL outcomesAchieving satisfaction for patients interested in a multifocal IOL begins with comprehensive preoperative screening and evaluation.
What role does chromatic aberration play in IOLs?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.
LASIK enhancements for premium IOLs more accurate with less dry eyeOphthalmologists 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.
Multifocals show similar results but lower power offers better vision rangeBoth the Tecnis multifocal +2.75 D and +4.00 D IOLs had good visual results, but the +2.75 D IOL had a better range of vision across near, intermediate, and distance.
Tips for successful surgery with secondary IOLsAphakic eyes that have no or inadequate capsular support can pose a significant challenge to cataract surgeons. Careful attention to the preoperative considerations, appropriate intraocular lens choices, surgical techniques, and postoperative management can ensure optimal results.
Toric trifocal IOL brings expanded range of functional vision to larger patient population
Toric trifocal IOL brings expanded range of functional vision to larger patient populationTrifocal IOLs can provide good uncorrected vision at near, intermediate, and far. Outcomes in a series of 30 patients show that a toric version of a trifocal IOL (AT Lisa tri 939MP, Carl Zeiss Meditec) delivers those benefits for patients with > 1 D of corneal astigmatism.
