TOPOGRAPHY-GUIDED PRK

Recently, at the CLEI Center for Keratoconus we have started offering an innovative new treatment for keratoconus: topography-guided PRK (photorefractive keratectomy) combined with corneal crosslinking.

Topography-guided PRK (TG-PRK) is a laser procedure which may improve visual function in select KC patients.  PRK (photorefractive keratectomy) is similar to LASIK, which is used to correct nearsightedness and astigmatism.  In keratoconus, however, the laser is used to reduce corneal optical irregularities.  TG-PRK achieves this by incorporating your individual corneal topography map into the laser treatment.  By utilizing your custom corneal topography data, the laser reshapes your corneal surface to improve your corneal optical architecture and visual performance.  The goal is to improve the corneal shape in order to improve visual quality with glasses or contact lens fit depending on your problem.  Some patients may also note general improvement in visual function.

 

In some cases,  adjunctive procedures on patients who have had CXL and TG- PRK can be performed with encouraging results.

 

So, for the patient with keratoconus, it is important to know that , although KC is a chronic disease, a stepwise treatment plan can get you the best longterm vision.  Although, not all procedures are for everyone, a tailored approach over time may combine a variety of procedures to optimize your corneal shape and visual outcome.
