TransPRK Laser Surgery
A no-flap, no-incision refractive surgery where the laser ablates directly from the corneal surface, offering the best corneal biomechanical preservation.
TransPRK is a 'no-touch' surface corneal refractive surgery. Unlike SMILE and LASIK, TransPRK requires no corneal flap or incision—the excimer laser ablates layer by layer from the corneal epithelium through the stroma to achieve refractive correction. This approach preserves corneal biomechanical integrity and eliminates flap-related complication risks. The trade-off is slower recovery compared to SMILE and LASIK, requiring 3-5 days for epithelial healing with associated pain and discomfort. It is ideal for patients with thin corneas, those in contact sports, or those prioritizing corneal safety.

Who Is This For
Is TransPRK Laser Surgery Right for You?
Good Candidates
- Thin corneas unsuitable for LASIK
- Contact sports athletes or physical laborers
- Those concerned about flap safety

- Keloid tendency
- Severe dry eye
- Under 18 or unstable refraction
Step-by-Step Process
How TransPRK Laser Surgery Works
Preoperative preparation
Topical anesthesia, disinfection, eye fixation.
Epithelial ablation
Excimer laser removes the corneal epithelial layer.
Stromal ablation
Laser continues to ablate corneal stroma according to preset refractive parameters.
Cooling and irrigation
Cold BSS irrigation of corneal surface to reduce thermal damage.
Bandage contact lens
Therapeutic contact lens placed to protect the surface and promote epithelial healing.
Single procedure, both eyes done same day. Bandage lens removed after 3-5 days when epithelium heals.
Cost Information
Cost Estimate for TransPRK Laser Surgery
Estimated Price Range
¥12,000 – ¥28,000
What's Included
Public tier-3A International Medical Department: approximately ¥12,000-20,000 (both eyes); premium private eye centers: approximately ¥18,000-28,000 (both eyes). Surface ablation has lower cost than SMILE or LASIK.
Before Your Visit
What to Prepare
Required Tests & Examinations
If you already have recent valid test results, bring the reports. If not, these assessments can usually be completed in China before the procedure.
Cycloplegic refraction
Corneal topography
Corneal pachymetry
Pupil size measurement
Dry eye evaluation
Fundus examination
Documents & Materials to Bring
Required to Bring
Passport and valid visa
Refraction records from past 2 years
Contact lens discontinuation proof
After Treatment
Recovery & Follow-Up
Significant pain and tearing for 2-3 days is normal
Visual recovery is slower; functional vision in ~1-2 weeks
Final stable vision takes 1-3 months
Use prescribed steroid drops to prevent corneal haze
UV protection for 6 months post-surgery
Avoid rubbing eyes
Follow-Up Schedule
Follow-up at day 1, day 3, day 5 (lens removal), week 1, month 1, month 3.
