Other Types of Refractive Surgeries

33153_400pxAlthough LASIK is the most common refractive surgery, there are occasions when other surgical methods may be more suitable.

PRK

PRK (photorefractive keratectomy) is the original excimer laser vision correction procedure. Since it was developed in the late 1980s, over 1 million PRK surgeries have been performed worldwide. PRK differs from LASIK in that no flap is made. The doctor simply removes the cornea's outermost epithelial cell layer. The excimer laser then removes microscopic amounts of tissue from the corneal surface. PRK is often preferred when the cornea is too thin to safely allow for a LASIK procedure. Visual outcomes for PRK are the same as LASIK outcomes, although it may take slightly longer for the vision to stabilize. There can be more pain and discomfort immediately after PRK than what is typically experienced with LASIK.

VISIAN PHAKIC ICL

The Visian Phakic ICL is inserted into the eye through a small, micro opening.  The lens then gently unfolds in the eye and is positioned between the iris and the natural lens where it stays indefinitely.  The Visian Phakic ICL is especially good for patients who are outside the parameters for traditional laser vision correction.  The lens provides exceptional visual acuity in most patients, and is invisible and undetectable in your eye.

Clear Lens Exchange

Patients who require a refractive correction outside the treatment allowance for the excimer laser may be good candidates for a clear lens exchange.

Clear lens exchange involves the removal of the clear natural lens of the eye, even though there is no cataract.  In some cases, the lens may have an early cataract which does not significantly interfere with corrected vision, and which would normally not require surgical removal.  Once the surgeon removes the natural lens of the eye, an intraocular lens implant (IOL) will be implanted in its place in order to restore vision. The doctors at Casey Vision Correction Center will discuss this option if appropriate.

 

 

Premium Intraocular Lens Surgery

In addition to laser vision correction and clear lens exchange offered at the Casey Vision Correction Center, Casey Eye Institute also offers other surgical options to help reduce your dependence on glasses or contacts. Premium Intraocular lens-based solutions may be appropriate for some people. For example, if you have been told you are not a good candidate for LASIK or are experiencing presbyopia (natural aging of the eye) and desire a multifocal solution, you may be a good candidate for a Premium IOL-based procedure.
