With the material and square-edge design of the AcrySof IQ IOL, patients have clearer vision after surgery, which in turn reduces the number of secondary procedures I need to perform. Using the YAG laser after cataract surgery to perform a capsulotomy may increase the risk of retinal detachment, and an open capsule makes it very difficult to remove or reposition an implant.
Range from 1. Important Product Information. Cataract surgery has become extremely sophisticated, with every critical element mapped out for optimal outcomes. Incisions are designed to leave the smallest optical footprint, minimizing surgically induced astigmatism. To insert the lens through the smallest incision possible, we rely on the thin design and elasticity of our IOLs.
The more elastic the lens is, the easier it is to fold it and insert it into the eye. The AcrySof IQ lens has a higher refractive index versus other aspheric IOLs and has excellent elasticity, allowing me to fold it easily without kinking or twisting. I implant this IOL though a 2. The single-use injector has a smooth feel and a depth-guard nozzle to help ensure accurate and consistent placement. Although the AcrySof IQ lens material is malleable, the lens and its haptics have shape memory.
As the IOL slowly unfolds, it assumes its optimal form inside the capsular bag. The design and mechanics of this IOL help with precise centration. Controlling stability ensures effective lens position leading to the best optical predictions and outcomes. After surgeons master the IQ base lens, they can incorporate optics to correct astigmatism and presbyopia.
The aspheric IQ lens mimics the human crystalline lens shape to help achieve the best optical quality for patients. Aspheric lenses are designed to reduce spherical aberrations halos and improve contrast sensitivity. This is particularly useful to patients as they read or perform tasks in dim lighting. In the young eye, positive corneal aberrations are compensated by negative spherical value in the crystalline lens.
As the eye ages, the spherical value of the lens gradually becomes positive, causing image quality to be less clear on the periphery in eyes with pupils that are 4 mm or larger.
This improves image clarity and contrast sensitivity, particularly on the perimeter. Retaining some positive spherical value is the goal, as studies have shown a small positive spherical aberration represents optimal vision. At the end of the day, cataract surgery is about patient outcomes. Patients want to perceptually see the best they can.

Visual symptoms may be significant enough that the patient will request explant of the multifocal IOL. The AcrySof platform's biocompatible hydrophobic acrylic polymer is different from other lens materials, because it offers a high level of fibronectin, which helps bind the IOL to the capsule.

Tecnis eyes had lower totals of higher-order aberrations, and Akreos eyes had greater depth of field. But acuity and contrast sensitivity did not differ statistically. Asked about visual quality, 28 percent of subjects judged it as better in the Akreos eye, while 14 percent picked the Tecnis eye—and 58 percent had no preference.
Either go for perfection or forget it. So, for nearly all of his cataract patients who have not had refractive surgery, Dr. Pepose neither adds nor subtracts spherical aberration. He uses a zero-aberration IOL. Preserving corneal spherical aberration has the added advantage of making the eyes more tolerant of defocus, he said. Devgan and Pepose both said. They recommend using a toric IOL for astigmatism greater than 1. About Foundation Museum of the Eye.

In addition, patients should be warned that they will need to exercise caution when engaging in activities that require good vision in dimly lit environments, such as driving at night or in poor visibility conditions, especially in the presence of oncoming traffic. It is possible to experience very bothersome visual disturbances, significant enough that the patient could request explant of the IOL.
Prior to surgery, physicians should provide prospective patients with a copy of the Patient Information Brochure available from Alcon informing them of possible risks and benefits associated with these IOLs.
