PRK vs. LASIK: Which Vision Correction Surgery is Right for You?

 When considering vision correction surgery, it’s important to understand the options available to you. PRK and LASIK are two of the most popular procedures, each with unique benefits and considerations. At Shinagawa Eye Centre in Singapore, we offer both procedures and can help guide you in choosing the best option for your eyes. Here’s a breakdown of PRK vs. LASIK to help you make an informed decision.

Understanding the Procedures:

PRK: PRK is one of the earliest forms of laser vision correction and is still widely used today. In PRK, the outer layer of the cornea (the epithelium) is gently removed, and the underlying corneal tissue is reshaped using an excimer laser. This procedure is particularly beneficial for patients with thin corneas, as it does not involve creating a corneal flap.

LASIK: In LASIK, a thin flap is created in the cornea using either a femtosecond laser or a microkeratome blade. This flap is then lifted, allowing the excimer laser to reshape the underlying corneal tissue. The flap is then repositioned, where it heals quickly. LASIK generally involves a faster recovery period and less discomfort compared to PRK.

Comparing the Benefits:

Speed of Visual Recovery: LASIK patients often experience rapid improvement in vision, typically within a day or two. In contrast, PRK involves a longer recovery timeline; it can take a few weeks for vision to stabilize as the epithelial layer regenerates.

Postoperative Comfort: LASIK is generally associated with minimal postoperative discomfort, thanks to the quick healing of the flap. PRK patients may experience more discomfort initially as the surface of the eye heals.


Long-term Outcomes:

Both PRK and LASIK provide excellent long-term outcomes for vision correction. The choice between the two often depends on specific anatomical considerations and personal preferences.

Safety and Risks: PRK does not involve creating a corneal flap, which eliminates the potential complications related to the flap. However, LASIK’s modern techniques have also minimized these risks significantly, making it a safe option for most candidates.

Who is a Good Candidate? Patients with thin corneas, irregular corneal surfaces, or those who engage in contact sports might be better candidates for PRK. Meanwhile, those looking for a quicker recovery and minimal discomfort might prefer LASIK.

At Shinagawa Eye Centre, our expert team is here to guide you through the decision-making process. We’ll conduct a thorough examination, discuss your lifestyle needs, and help you choose the procedure that best suits your vision goals and health.
