Astigmatism is a condition where the cornea (the front window covering of the eye) is oval rather than round. This results in blurred vision and ghost images around objects. In order for light to focus precisely, the cornea needs to be as round as possible. Years ago the correction of astigmatism was one of the greatest hurdles to an excellent LASIK result. Now, with amazing advances in LASIK such as ACE™ Eyetracking technology, it has become routine to fix even severe cases of astigmatism.
Advanced Control Eyetracking (ACE)
One breakthrough in the correction of astigmatism is the use of Advanced Control Eyetracking (ACE™) Technology. The most advanced eye tracker in the industry allows the laser to use active radar to follow any eye movement during the procedure, virtually eliminating the possibility of laser pulses being applied in the wrong place. This revolutionary Iris Recognition technology scans the unique pattern of your iris and then uses a dynamic eye-tracking system in the laser to properly align treatment during the procedure. LASIK with ACE™ Eyetracking Technology precisely adjusts the treatment to correct for microscopic eye movements during the procedure leading to:
- Unprecedented accuracy of correction and visual outcome…especially for patients with astigmatism
- Improved patient safety
- Reduced retreatment rate
We offer Advanced Control Eyetracking (ACE™) Technology to all LASIK or PRK patients at no additional charge!
Limbal Relaxing Incisions (LRI)
LRI is a procedure which corrects astigmatism by using incisions to relax the tension in the cornea that causes it to be out of round. Incisions are placed near the junction of the white and colored part of the eye (the limbus), expand the cornea and effectively convert an oval to a circle, thereby correcting the astigmatism. LRIs can be done as a stand alone procedure or can be performed in conjunction with cataract and/or refractive lens implant surgery.
Toric Lens Implants
The Toric IOL is an advanced lens implant used during cataract or refractive lens surgery and has your astigmatism power incorporated into the lens optic to provide a precise way to reduce or eliminate astigmatism at the same time it corrects cataracts and/or a patient’s prescription. The Toric IOL is inserted into the eye and then rotated into alignment with the direction of the astigmatism as determined by the preoperative measurements and scans. There are no additional incisions required for this alternative. This allows for much greater levels of astigmatism correction and more precision than can achieved with LRI incisions.
