HDSA – High Definition Surface Ablation
While LASIK is undoubtedly an amazing procedure, it is not the best option for every patient. Some of our Lexington patients may not qualify as candidates for LASIK because their prescription is not within the approved range or their corneas are too thin. At Medical Vision Institute we have developed a patented technique known as High Definition Surface Ablation (HDSA) that combines the safety of PRK with some enhancements to promote an accelerated recovery. HDSA uses an excimer laser to reshape the cornea just like PRK. The difference is our specially developed technique, which uses medicated contact lenses and eye drops to help the patient recover faster to start enjoying their results.

The Benefits of HDSA
HDSA offers the people of Lexington the same results you can achieve with LASIK, but without the need to create a flap in the cornea. This provides several benefits, including:

  • A lower chance of surgical complications. LASIK is extremely safe, with a very low complication rate. When complications do occur, however, they are often related to the flap that is created in the beginning of the LASIK procedure. HDSA eliminates the flap and its associated risks.
  • Increased safety. The flap created during LASIK often heals quickly, by injuries or trauma can dislodge it months or even years later. If your job or lifestyle puts you at high risk for eye injury, HDSA would be a safer option.
  • A higher range of prescriptions can be treated. Since HDSA eliminates the creation of the flap and treats the surface of the cornea, there is a greater thickness of tissue available to treat. This means that higher prescriptions can be treated without the risk of thinning the cornea too much.
