Tecnis Multifocal and AcrySof Toric IOLs
Premium Lens Cataract Surgery
New advances in cataract surgery and intraocular lens implants (the artificial lenses used to replace the human lens) have resulted in a new form of refractive surgery. Now, cataract surgery and clear lens extraction (CLE) can not only restore vision lost because of cataract formation, but also improve vision in individuals whose refractive error is too great for Laser Vision Correction.
Tecnis® Symfony Extended Depth of Focus and AcrySof Toric Lens Implants
Although there are several technologies available to correct presbyopia ("elder vision") during cataract surgery, we prefer to use diffractive multifocal (DMF) type intraocular lenses. In our doctors" experience, the Tecnis® Symfony intraocular lens delivers the best potential for freedom from reading glasses or bifocals for patients electing cataract or CLE (clear lens extraction) procedures. For those requiring correction for astigmatism to improve uncorrected vision at distance, our go to lens is the Symfony Toric. These lenses are capable of correcting a large amount of astigmatism while correcting near vision as well. For those not wishing to correct near vision, Excellent monofocal options can be utilized..
How do these lenses compare to conventional monofocal lenses?
During clinical studies, Over 90% of patient’s found that they no longer needed their glasses after having these lenses placed in both eyes, compared to spectacle independence in only 8% of patients with monofocal lenses..
Tecnis Symfony IOL (note diffractive rings)
Other advantages include:
• Full range of vision. With this increase in vision quality, DMF patients are able to pass the visual acuity portion of the driver's license exam, in most states, unaided by glasses or contact lenses.
• The ability to read small type quickly and easily. While only one of 13 patients with any other IOL could read small type, four of five DMF patients were able to read small type without reading glasses.
• Better vision in all lighting situations. Whether in brightly or dimly lit conditions the apodized diffractive optics of the DMF lens minimizes the occurrence and severity of visual disturbances compared to other multifocal technology
As with any surgical procedure, there are associated risks and benefits. While there may be a decrease in the need for glasses, some patients may occasionally notice rings around lights at night. These side effects may make it more difficult to drive at night or perform tasks in low light conditions although most patients report they diminish over time. While virtually everyone experiences an improvement in vision after cataract surgery, some people will have better uncorrected vision than others. Therefore, it is important to discuss the potential risks and benefits with your doctor who will let you know if the AcrySof ReSTOR® or Tecnis DMF lens is right for you.
