TransPRK vs LASIK – As Explained by A Surgeon

TransPRK vs LASIK / iLASIK – As Explained by A Surgeon

What is LASIK?

LASIK is an eye surgery that treats myopia, astigmatism, and presbyopia. It is a well-researched and established procedure, the gold standard in vision correction, that has over 20 years of proven results. As compared to glasses and contact lenses which only provide temporary vision correction, it is able to grant individuals 24/7 correction of vision.

*iLASIK is a newer LASIK method that is an improvement of traditional LASIK. iLASIK is the only LASIK method safe and accurate enough to be usesd for NASA Astronauts and US Navy SEALs.

What is TransPRK?

As the refractive surgery industry continues to develop, more and more treatment methods have been made available – TransPRK being one of them. So, what is the difference between the procedures? Which one is better?


The diagram below highlights the differences in treatment process between TransPRK and LASIK.

TransPRK vs LASIK Lee Hung Ming Eye Centre Singapore

Step 1: Preparation of Cornea

LASIK/iLASIK: An IntraLase Femtosecond laser creates a uniform layer of microscopic bubbles just beneath the surface of the eye.

TransPRK: A Schwind Amaris 1050RS laser vaporizes the corneal epithelium cells.

NOTE: Both methods are bladeless, all-laser, no-cut, and no-touch.

Step 2: Reshaping of Cornea

All methods: This step is the same in both methods. An excimer laser is used to reshape the cornea, refractive errors (myopia, astigmatism, presbyopia) are corrected.

Step 3: Post-Op Recovery

LASIK/iLASIK: After 1-3 days, vision is generally clear enough for patients to return to work or school.

TransPRK A bandage contact lens needs to be worn for 5 days for the vaporized epithelium to heal. Patients can return to work or school after 1-2 weeks.

TransPRK vs LASIK – Common Myths & Misconceptions

Misconception: Flap methods (LASIK, iLASIK) are dangerous and cause flap complications. Flapless LASIK methods (TransPRK, Epi-LASIK) do not have any complications.


This is untrue. It could be argued that TransPRK causes more trauma to the eye than LASIK as the corneal epithelium has to be vaporized. This means that with TransPRK, the chances of corneal scarring and infection are higher, it is more painful, and recovery time is longer. Both methods have possible side effects – including dry eyes, halos and glares, increased light sensitivity

Patients need to bear in mind that, regardless of the type of treatment (TransPRK vs LASIK), there are inherit risks in every surgical procedure. In general, LASIK treatments have excellent safety profiles and high success rates. The best way to minimize post-surgical complications is to choose an experienced surgeon whom you feel comfortable with.

Misconception: TransPRK does not touch the eye. Therefore, TransPRK is safer.


False. All LASIK treatments involve contact with the eye. This may be in the form of surgical instruments or lasers. As of this time of this article, all treatments make use of an excimer laser to reshape the cornea. Older methods used blunt microkeratome blades. Newer methods use high-tech lasers (IntraLase laser in LASIK, Schwind Amaris laser in TransPRK).

Misconception: One will always have to worry about flap complications after LASIK and will never be able to play contact sports again.


False. In most cases, the flap heals after a month. After recovery, the cornea returns to normal. Patients are able to resume playing contact sports (tennis, basketball, soccer, etc.) after a month. In addition, if you were to be hit directly in the eye during contact sports, you are likely to sustain eye injuries, regardless of the type of surgery you had done.

Misconception: ____ treatment is the best option for every patient.

Explanation: False. There is no one-fits-all treatment. Each method has its pros and cons. An eye assessment will be able to let you know which is best for you. Find a clinic that has multiple treatment options and a good track record.
