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.
Toric IOL’s transitional conic design enhances tolerance to misalignmentA 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.
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.
AD-IOLs mimic movement of natural lens
AD-IOLs mimic movement of natural lensAccommodating-disaccommodating IOLs are being developed that mimic the movement of the young crystalline lens through the use of “Zonular Capture Haptics” technology.
Achieving patient satisfaction with multifocal IOLsMultifocal IOLs offer the potential to reduce spectacle dependence, but outcomes vary depending on optical design. Optimizing success and satisfaction depends on careful patient selection, thorough counseling, and good surgical technique.
Novel trifocal IOL extends range of visionA new non-apodized diffractive trifocal IOL allows 88% energy utilization and sends energy to near (40 cm), a preferred intermediate distance (60 cm), and far (infinity). Early results for visual acuity, contrast sensitivity, and photopic symptoms are encouraging.
