Non-Laser Vision Correction Techniques offered at University of Colorado Hospital

Thanks to depth of their expertise, our surgeons offer a full spectrum of vision correction options not available in most other centers. 

Intraocular contact lens (ICL) also called implantable collamer lens

For many years, doctors have been treating cataracts by replacing diseased lenses with intraocular lens. This technology has now been adapted to also correct refractive errors to improve vision. Your doctor inserts the lens through a microscopic incision in the eye. The lens is made of collamer, an advanced lens material that is highly biocompatible. Your natural lens is not removed and works with the new lens to correct vision.  Further corrections or removal are possible if necessary. This technique is highly effective in improving vision and may be an option for patients who are not candidates for lasik surgery or other procedures.

Radial and Astigmatic Keratotomy and Limbal Relaxing Incisions  (RK, AK, LRI)

In these techniques, a very sharp blade is used to cut deep incisions in the surface of the cornea.  This alters the shape of the cornea to help improve vision.

RK has become less popular since the approval of the excimer laser.  AK and LRI are still used in conjunction with laser vision correction techniques to touch up the initial result and correct astigmatism.
