How TransPRK Fixes Astigmatism: What Athletes Need to Know
Astigmatism blurs your vision at all distances — but for athletes in Seoul, it can mean the difference between peak performance and persistent visual frustration. Discover how TransPRK/2-Day LASEK corrects astigmatism permanently.
Q. Does TransPRK Fix Astigmatism in Athletes?
Yes. TransPRK (transepithelial photorefractive keratectomy) is one of the most effective surgical treatments for astigmatism — and is particularly well-suited for athletes because it requires no corneal flap, eliminating the risk of flap dislocation from contact sports, helmets, or water activities. At Nunehim Eye Center in Yeongdeungpo, Dr. Daniel Baik, board-certified ophthalmologist, performs TransPRK/2-Day LASEK to deliver precise correction for myopia combined with astigmatism in a single, flapless procedure.
Q. What Is Astigmatism and How Does It Affect Athletic Performance?
Astigmatism is a refractive error caused by an irregularly shaped cornea or lens, resulting in blurred or distorted vision at all distances. For athletes — whether cyclists navigating Guro’s night roads, swimmers in Gasan’s indoor pools, or martial artists competing in Gwanak — astigmatism means impaired depth perception, difficulty tracking fast-moving objects, and eye strain that worsens with high-demand visual activities. In Korea, where sports participation is extremely high and nearly 40% of myopic patients also have clinically significant astigmatism, this is a common and correctable performance barrier.
Q. What Are the Signs of Astigmatism in Athletes?
- Blurred or distorted vision at all distances, not just near or far
- Difficulty tracking fast-moving balls, opponents, or targets
- Eye fatigue and headaches during or after training
- Halos or ghosting around lights during evening outdoor sports
- Frequent need to squint to see clearly
- Reduced performance in precision sports (archery, shooting, tennis)
- Contact lens discomfort or unstable vision with toric lenses during activity
📊 Astigmatism & Sports in Korea — Key Statistics
▸ ~75% of Koreans with myopia have co-existing astigmatism of 0.75D or more (Korean Journal of Ophthalmology)
▸ TransPRK achieves 20/20 or better vision in over 95% of patients with mild-to-moderate astigmatism (JCRS, 2022)
▸ No flap complications: TransPRK eliminates flap-related risks entirely, critical for contact sport athletes
▸ Full visual recovery for TransPRK/2-Day LASEK: typically 5–7 days, with stable vision by week 4–6
Q. How Does TransPRK Correct Astigmatism Step by Step?
TransPRK uses an excimer laser to remove a precisely calculated amount of corneal tissue in a single pass — without cutting a flap. Unlike LASIK, the entire ablation (including epithelium removal and stromal reshaping) is performed by the laser in one continuous step. For astigmatism, the laser reshapes the cornea from an oval (toric) curve to a rounder, more spherical profile, eliminating the unequal refractive power that causes blur.
The procedure takes approximately 10–15 minutes per eye. At Nunehim Eye Center, Dr. Daniel Baik plans each treatment using corneal topography and wavefront data to ensure the most accurate astigmatism correction for patients in Yeongdeungpo, Guro, Gasan, and Gwanak. The 2-Day LASEK protocol means you can return to light activity within a few days, with full athletic clearance typically at 4–6 weeks.
Q. Why Is TransPRK Preferred Over LASIK for Contact Sports Athletes?
LASIK creates a corneal flap that, while healing securely in most patients, carries a small but real risk of flap dislocation from direct eye trauma — a concern for boxers, martial artists, rugby players, and combat sports athletes. TransPRK is completely flapless: the laser treats the cornea surface directly, leaving no flap that could shift or wrinkle. This makes TransPRK the preferred option at Nunehim Eye Center for athletes participating in contact or high-impact sports across Seoul’s Guro, Gasan, and Gwanak districts.
Note: Nunehim Eye Center specialises in TransPRK/2-Day LASEK. SMILE LASIK is not offered at our clinic. Dr. Daniel Baik will advise which procedure is most appropriate for your corneal profile, astigmatism degree, and athletic activities during your consultation.
Q. Are There Athletes Who Are NOT Suitable for TransPRK?
- Corneas that are too thin for safe ablation (keratoconus screening required)
- Very high astigmatism above the safe treatment range
- Active eye infections or severe uncontrolled dry eye
- Unstable prescription (refraction should be stable for at least 12 months)
- Pregnant or breastfeeding athletes (treatment is deferred)
Days 1–5
Protective lens in place. Some discomfort and blurred vision normal. Light indoor activity only. No swimming or contact sports.
Weeks 1–4
Vision improving daily. Non-contact cardio (running, cycling) permitted from week 2. Eye drops continued. Avoid water sports and eye rubbing.
Month 2+
Full athletic clearance including contact sports, swimming, and martial arts. Vision typically stable and crisp. Final review with Dr. Baik.
From Dr. Daniel Baik, Board-Certified Ophthalmologist
“I see many athletes from the Yeongdeungpo, Guro, and Gasan areas who are frustrated by contact lenses that shift during competition or glasses that fog up during training. TransPRK astigmatism correction is particularly rewarding in athletic patients — the visual clarity they achieve post-operatively, combined with the safety of a flapless procedure, genuinely transforms how they experience their sport. We take a highly personalised approach to each patient’s corneal shape and astigmatism axis to maximise the outcome.”

❓ Frequently Asked Questions — TransPRK & Astigmatism for Athletes
Q. How much astigmatism can TransPRK correct?
TransPRK can typically correct astigmatism up to approximately 5–6 diopters, depending on corneal thickness and topography. Dr. Daniel Baik assesses each patient individually at Nunehim Eye Center to determine whether the full astigmatism correction can be achieved safely in a single procedure.
Q. How soon can I return to competitive sport after TransPRK?
Most athletes can resume non-contact training (running, cycling, gym) within 2 weeks of TransPRK/2-Day LASEK. Contact sports and water sports are generally cleared at 4–6 weeks. Dr. Baik provides a personalised return-to-sport timeline at your post-operative consultation.
Q. Will astigmatism come back after TransPRK?
TransPRK produces permanent corneal reshaping. Astigmatism does not typically return after the procedure in patients with stable refraction. A small residual correction may remain in cases of very high astigmatism, which can be addressed with an enhancement procedure if needed.
Q. Can I wear contact lenses before my TransPRK surgery?
Soft contact lens wearers should stop wearing lenses at least 2 weeks before surgery. Rigid gas-permeable (RGP) or OK lens wearers need a longer cessation period of 4–8 weeks. This ensures accurate corneal topography mapping for your astigmatism treatment plan.
Q. Is TransPRK painful?
The procedure itself is painless — numbing drops are used. Post-operatively, patients typically experience moderate discomfort and light sensitivity for 2–4 days while the corneal epithelium heals. This is managed with prescribed eye drops and oral analgesics if needed.
Q. Does Nunehim Eye Center offer TransPRK in English?
Yes. Dr. Daniel Baik and the team at Nunehim Eye Center in Yeongdeungpo provide full consultations and post-operative care in both Korean and English. International athletes and expats residing in Guro, Gasan, Gwanak, and across Seoul are welcome.
Q. What is the cost of TransPRK for astigmatism in Seoul?
TransPRK pricing varies based on the degree of myopia and astigmatism, corneal measurements, and any additional diagnostics required. Nunehim Eye Center offers transparent pricing with a detailed quote provided after your initial examination. Visit nunehim.com or contact the clinic directly.
