No blades, no cuts, no flaps
Surface cells removed, cornea reshaped in a single step
Zero surgical instruments touching the cornea
What is Safe Sight TransPRK ?
Safe Sight TransPRK (Transepithelial PhotoRefractive Keratectomy) is surface-based laser vision correction procedure which does not require the eye surgeon to cut a corneal flap. Instead, a single laser is used to remove the outermost cells, which then goes on to reshape the cornea tissue to correct refractive error in one seamless and efficient step. With modern technology, Safe Sight TransPRK can eliminate some of the risks in the standard LASIK (cut, flap and zap) procedure such as flap-related medical complications.
How does Safe Sight TransPRK work?
Safe Sight TransPRK at Clearvision is fast, simple and safe. In Safe Sight TransPRK, there are no surgical devices touching the eye at all, making it a truly all laser procedure.
We use the modern, Schwind Amaris 1050RS excimer laser. The Schwind Amaris 1050RS laser is equipped with a zero latency eye tracker and the ability to track all 7-dimensions of the eye’s movements, resulting in fast and accurate treatment.
Step1: Patient lies down and simply looks ahead at a blinking fixation green light. No suction ring nor surgical instrument touches the eye.
Step 2: Epithelium cells are removed with the Schwind Amaris 1050RS laser.
Step 3: Laser goes on to reshape the cornea curvature to correct the refractive power in one step seamlessly.
Step 4: A high-oxygen permeability content contact lens is then placed over the cornea to act as a bandage, protecting the treated area while the surface cells regenerate.
Step 5:The surface cells take 3 to 5 days to regenerate. It is important to use the eye drop medications prescribed and protect your eyes from sunlight to ensure proper recovery. The bandage lens will be removed after 5 days, when the surface cells have fully healed.
Corneal Cross-Linking (CXL)
CXL is an additional treatment to the Safe Sight TransPRK procedure that helps to strengthen the cornea through corneal collagen cross-linking. It is a relatively fast procedure, taking an additional two minutes of time.
Using the Avedro KXL system, CXL can help to minimize the weakening effects that comes with the laser sculpting of the cornea in refractive surgeries. As laser sculpting with the excimer tissue involves tissue ablation, corneas will naturally become thinner after refractive surgeries. The higher your spectacle power, the more corneal tissue is required in laser sculpting.
CXL is especially suitable for patients with:
- Thin or weak cornea
- Very high spectacle power
