The Advantages of PRELEX Cataract Procedures

Cataracts are a serious medical problem that will affect four out of ten adults over the age of 60, and almost 70% of adults over the age of 75.  Cataracts, a clouding of the lens in the eye, can result in impaired vision and even blindness.

The PRELEX Procedure

One of the surgical procedures used to treat cataracts is Presbyopic Lens Exchange, or PRELEX.  In this procedure, a small incision is made in the eye, the diseased lens is removed, and an artificial, intra-ocular lens (IOL) is replaced.

Why PRELEX for Cataracts?

Along with cataracts, many adults, as they age, begin suffering from what is known as presbyopia, a condition that prohibits the ability to focus on close objects.  The advantages of the PRELEX procedure for cataracts are that the procedure can fix two problems with one procedure.  Also, the PRELEX procedure has these added benefits:

  • Elimination of any chance for future cataracts
  • Procedure can be performed on patients’ with corneas too thin for LASIK
  • Recovery of unaided distance vision
  • Recovery of unaided near vision

Further, the PRELEX procedure, in fixing the cataract and the presbyopia conditions, can severely limit or fully eliminate the need for glasses or contact lenses.

The PRELEX Experts

Cataracts can be debilitating, but you do not have to live with them.  Dr. Khanna and his team at the Khanna Institute of LASIK and Refractive Surgery are experts in performing the PRELEX procedure and can remove your cataracts while reducing or even eliminating your need for glasses or contacts.

What are Toric IOLs?

The 20 to 30 percent of cataract patients each year who also suffer from astigmatism have not always had the best options when it came to achieving complete vision improvement after cataract surgery. While their cataracts, and possibly any nearsightedness and farsightedness, could all be corrected with intraocular lens (IOLs), these patients’ astigmatism issues were not improved after the cataract removal and lens exchange surgery. Most of those patients had to remain in prescription glasses or contact lenses. Or they had to undergo another surgical procedure, such as LASIK, Custom LASIK or PRK, or a procedure called a limbal relaxation incision, which also alters the shape of the cornea. Today, the cutting-edge technology of premium Toric IOLs makes treating astigmatism in cataract patients a lot easier, and a lot more successful.

Toric IOLs and Astigmatism

Astigmatism, which is basically blurry vision from an irregularly-shaped cornea, is not a rare condition. In the U.S., it affects one in every six adults. Toric IOLs work to eliminate or reduce astigmatism by correcting the visual imbalance caused by the abnormal shape of the cornea. (A “perfect” cornea is circular. A cornea causing astigmatism is oval-shaped.)

Here are a few more facts about Toric IOLs:

  • They are safe and made from non-toxic, long-lasting silicone or acrylic.
  • They are flexible and easily inserted, with no history of after-implantation problems.
  • They are removable, if for any reason they need to be replaced with another IOL.
  • They are considered one of the most ideal solutions for patients with both cataracts and astigmatism.

Two Toric IOLs are manufactured right now, the STAAR® Toric IOL™ and the AcrySof® Toric IOL. The STAAR product has been FDA-approved for a decade now, and the AcrySof IOL has been approved for nearly five years.

Could a Toric IOL be the right choice for you?

The first step in determining if a Toric IOL is the best option for you is to have an experienced and knowledgeable cataract surgeon verify that you have a significant degree of astigmatism, in addition to a cataract that needs removal.

If your eye doctor finds that you do have a moderate to high level of astigmatism, you may want to pursue a Toric IOL placement.
