    Astigmatic Keratotomy (AK) – Scleral Recession

    Richard A Erdey, MD has developed this simple, effective method as an alternative to limbal relaxing incisions, Toric Intraocular lenses, or Laser Vision Correction to reduce or eliminate astigmatism during cataract or Visian ICL surgery. The cataract incision is modified and placed at the steepest part of the cornea. The cornea relaxes and flattens making the cornea less oval or football shaped (astigmatic) and more spherical. The effect is monitored under an intra-operative keratometer allowing additional adjustments to be made to improve the result. There is no need for a subsequent laser vision correction procedure performed several weeks after the cataract surgery.   Remove your cataract, reduce astigmatism and reduce dependence on corrective lenses  IN ONE CONVENIENT SITTING! 


    Before: cornea oval. astigmatism steep at 90 degrees

    After: Cornea spherical. Astigmatism neutralized

     

     

    Astigmatic Keratotomy (AK) – Limbal Relaxing Incisions

    Astigmatic Keratotomy (AK) is a modified form of Radial Keratotomy used to reduce astigmatism. Tiny, precise scratches are made on the cornea surface in a specific location in accordance with the steepest curve of the cornea. These scratches flatten the steepest part of the cornea. This makes the cornea more spherical (baseball shaped) and thus sharper retinal focus is obtained. This procedure takes just a few minutes to complete and can be performed alone or in conjunction with cataract surgery or Visian ICL implantation.
