Cataract Surgery is a common procedure in the U.S. Las Vegas Cataract surgery specialists see a variety of patients with varying degrees of vision loss due to cataracts. One common treatment for cataracts is an IOL or Intraocular lens replacement.Most patients undergoing cataract surgery have options regarding the type of IOL to be implanted in their eyes. The choice may depend largely on which type of vision correction will be most convenient for one’s lifestyle. In other cases, co-existing eye conditions limit the effectiveness of certain IOLs, leaving the patient with one clearly best option.
Cataract formation is among the leading causes of blindness. It is characterized by cloudy or opaque areas in the eye's natural lens that usually develop gradually with advancing age (environmental factors, metabolic diseases and certain medications can also accelerate cataract formation). In Las Vegas cataract surgery is often the preferred treatment in which an IOL is used to replace the damaged natural crystalline lens.
The goal of cataract surgery with a multifocal IOL is to restore some of the near focusing ability of your eye. There is no guarantee that all of the near focusing ability of your eye will be restored. Other factors affect the visual outcome of cataract surgery Las Vegas experts say, including the power of the lens implant, your individual healing response, pre-existing astigmatism, and the function of the ciliary muscles in your eyes. While a multifocal IOL can reduce dependence on glasses, it might result in less sharp vision, which may become worse in dim light or fog. It may also cause some visual side effects such as haloes around lights at night and faint double images when reading. Driving at night may be affected.
Prior to surgery, a number of measurements are done, called biometry, to calculate the power of the intraocular lens that will be implanted in the eye. While the methods used to calculate the power of the IOL implant are very accurate in the vast majority of patients, some inaccuracy may occasionally occur. As the eye heals, the implant can shift very slightly toward the front or back of the eye before a stable position is reached. The amount of this shift is not the same in everyone, and may cause you to see differently from what may have been predicted by the measurements taken before surgery. Patients who are highly nearsighted or highly farsighted have the greatest risk of inaccuracies. Patients who have had Las Vegas LASIK, PRK, or Radial Keratotomy (RK) are especially difficult to calculate precisely. Residual refractive error after surgery may be amenable to correction with eyeglasses, contact lenses, refractive surgery, or repositioning or replacement of the IOL itself.
News from Lenstec however, a provider of technologically advanced lenses for treating vision disorders – today announced that its Precision Series Softec HD Intraocular Lens (IOL) Implant for treating cataracts is available in an expanded range of prescriptions.The expansion announced today makes the Softec HD PS available to cataract patients throughout the most popular range of prescriptions.
Lenstec improves predictability with Precision Series IOLs by reducing the manufacturing variability (i.e., tolerance or margin of error) inherent in any manufactured lensThis reduced variability enables Las Vegas Cataract surgeons to more accurately match IOLs to each cataract patient's prescription.
