What is Trans-PRK (ASA)?

Advanced Surface Ablation (ASA), also known as Trans-PRK, is a revolutionary advancement in laser vision correction. Powered by the innovative Schwind Amaris platform with Smart Pulse Technology (SPT), this procedure is **touchless, bladeless, and flapless.**

Unlike traditional methods, Trans-PRK ensures a remarkably smooth corneal surface for excellent clinical outcomes, redefining speed, precision, safety, and patient comfort.

The Procedure Overview

  • ASA (Trans-PRK) utilizes Smart Pulse Technology to gently remove the outer layer of the cornea (epithelium) and reshape the cornea in a single, one-step laser process.
  • It eliminates the need for flap creation (like in LASIK) or lenticule removal (like in SmartSight or SMILE).
  • This ground-breaking approach guarantees a stress-free, non-invasive experience without the use of alcohol or surgical instruments on the eye's surface.

Benefits of Trans-PRK

  • Extremely Gentle: The Smart Surface procedure is exceptionally gentle, preserving maximum corneal stability and ensuring minimal impact on tear film production.
  • Minimal Risk: The one-step, no-touch process minimizes treatment time and eliminates all risks associated with a corneal flap.
  • Fast Healing: The epithelium heals within 2 to 3 days. A soft bandage contact lens is placed on the eye post-procedure for comfort.
  • Excellent Vision: Patients typically enjoy high-quality vision just 2 to 4 days after the cornea heals, ensuring a swift return to an active lifestyle.

Who is a Good Candidate for Trans-PRK?

Trans-PRK is a game-changer for those seeking clear vision without glasses. It is particularly well-suited for:

  • Active individuals, athletes, and those in high-risk jobs (pilots, divers, contact sports).
  • Patients with **dry eyes or thinner corneas** who may not qualify for LASIK or SMILE.

Your Trans-PRK Questions Answered

Trans-PRK, or Advanced Surface Ablation (ASA), is a "no-touch" laser vision correction. In one step, a laser gently removes the eye's outer layer (epithelium) and reshapes the cornea underneath. There is no blade, no flap, and no instrument touches the eye's surface.

  • vs. LASIK: Trans-PRK is "flapless." LASIK creates a thin flap on the cornea, which is lifted and replaced. Trans-PRK avoids all flap-related complications.
  • vs. SmartSight/SMILE: Trans-PRK is a "surface" procedure. SmartSight/SMILE work *inside* the cornea to remove a lenticule. Trans-PRK is often preferred for patients with thinner corneas.

Trans-PRK is an excellent choice for people with very active lifestyles, aversions to a "flap," or those in contact sports or professions where eye trauma is a risk. It's also the procedure of choice for many patients who have thinner corneas or pre-existing dry eye, as it preserves more corneal strength and typically causes less dryness.

The initial recovery is slightly longer than LASIK. The epithelium (surface layer) needs to heal, which takes about 2-4 days. During this time, a protective bandage contact lens is worn, and vision will be blurry. However, after this initial healing, vision improves rapidly. The long-term visual results are excellent and identical to LASIK.
