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.
Using dysfunctional lens syndrome stages, physicians can discuss a range of treatment options with patients, based on clinical findings and refractive error.
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.
Aphakic 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.
Both 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.
Trifocal 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.
Accommodating-disaccommodating IOLs are being developed that mimic the movement of the young crystalline lens through the use of “Zonular Capture Haptics” technology.
