Multifocal lenses are designed to improve upon monofocal intraocular lens implants (IOL) by using a technology called diffraction that allows for light to be focused at more than one point.  This allows the patient to decrease dependency on glasses for both reading and distance.  Up to 80% of patients with these lenses do not need to rely on glasses or contact lenses after surgery.  Please ask Dr. Salz if you are a candidate for a multifocal lens at your cataract consultation.

Astigmatism is a common problem that affects the refractive state of the eye.  Astigmatism occurs when the cornea, which is the clear front part of the eye, does not  have a completely round shape, more like a football rather than a basketball.  Astigmatism requires glasses, contact lenses, or refractive surgery to correct it.  However, during cataract surgery, special lenses, called Toric, can be placed, allowing for better vision.  This can reduce dependency on glasses after cataract surgery.  These lenses are usually used to improve distance vision but alternatively can be used to sharpen near vision if that is the patient's preference. To see if you are a candidate for an astigmatism correcting implant, please schedule a consultation.

These lenses, sometimes referred to as acommadating lenses, are designed to increase depth of focus and decrease dependence on glasses.  They can be a great option for many patients. Also, there is a new toric version of the Crystalens called the Trulign Toric IOL that can be beneficial for patients who are not candidates for the multifocal lens but want a broader range of vision.
