Advanced Refractive Cataract Surgery

Best option for the individual who would like to achieve his/her best distance vision but is willing to wear glasses for reading or close work.

Surgical procedure includes:

  • Insertion of advanced technology Acrysof® Toric® (astigmatism correcting) Implant; or
  • Astigmatism correction surgical procedure(s) if appropriate

Pre-operative testing includes:

  • Measurement of the curvature of the eye
  • Measurement of the length of the eye
  • Orb-scan measurement of the shape of the cornea
  • Ultrasound measurement of thickness of the cornea
  • Ocular Coherence Tomography to evaluate macular health
  • WaveScan evaluation with calculation of the eye's higher order aberrations as needed
  • Tests to determine the eye's tear production as needed

Post-operative care includes:

  • Multiple post-op refractions
  • Further astigmatism correction procedure(s) if appropriate
  • Laser vision correction if needed – NO CHARGE (normally $2,500 per eye)

The cataract procedure itself is a covered service under most insurance plans.

Astigmatism Correction w/ the Acrysof® Toric® IOL

The Acrysof® Toric® intraocular lens (IOL) is specifically for individuals with astigmatism. This advanced technology IOL corrects astigmatism and can provide excellent distance vision without the need for glasses.  Many patients who chose the Acrysof® Toric® IOL are able to see well enough at distance not to require glasses or contact lenses.  The Acrysof® Toric® IOL can be combined with LRI (limbal relaxing incisions) for patients with large amounts of astigmatism.

Astigmatism Correction w/ Limbal Relaxing Incisions

0100-SL-AK3D-017Limbal Relaxing Incisions (LRIs) can be placed at the time of cataract surgery to reduce or eliminate corneal astigmatism.  LRIs are tiny incisions placed at the junction of the clear and white part of the eye (limbus) using a diamond scalpel.  The depth and length of the incisions is determined by the surgeon using preoperative testing including Orbscan (corneal surface mapping) and Pachymetry (corneal thickness measurement).  The goal of LRIs is improved vision without glasses after cataract surgery.

 

What is Astigmatism?

Astigmatism is present when the surface of the eye (cornea) is not perfectly round. The cornea with astigmatism may be thought of as being shaped like a football rather than being shaped like a basketball. In most eyes with astigmatism, the oblong or oval shape causes light rays to focus on two points in the back of the eye, rather than on just one, causing images to appear out of focus.  Corneal astigmatism is normally not corrected by cataract surgery.  In order for the eye to focus clearly without glasses or contacts after cataract surgery, significant corneal astigmatism must be corrected.
