"The concept behind a dual-optic accommodating system is to be able to place a very high-powered moving optic in every eye and then use a rear minus optic to adjust the net power to whatever is needed for the individual eye," he says.The surgeon uses a plunger to advance the lens into the eye, one optic at a time.The injector requires a larger incision than for current monofocal IOLs, and I prefer about a 3.7- to 3.8-mm incision, as measured with an incision gauge.""The capsulorhexis must be small enough to completely overlap and restrain the forward-moving anterior optic," Dr. "If the capsulorhexis is too large, or it's eccentric so that it fails to overlap one part of the anterior optic edge, you can't insert the lens."The surgeon also has to get visually oriented as to what part of which optic is emerging out of the injector first," Dr. "Typically, you have to make minor manipulations to properly position the two optics.The outcomes show comfortable near vision, higher patients’ satisfaction rates, and minimal postoperative complications like Posterior Capsular Opacification and Anterior Capsular Opacification, due to their design and material.La presbicia se produce en el ojo envejecido debido a los cambios en el músculo ciliar, las fibras zonulares y el cristalino, y al incremento de la esclerosis del mismo.
