LASIK vs PRK: Which Vision Correction Surgery Is Right for You?
&srotate=0)
Laser vision correction has transformed the lives of countless men and women across the globe by reducing or removing their dependence on glasses or contact lenses. At Ophthalmology Associates of the Valley (OAV) near Los Angeles, CA, our world-renowned team offers both LASIK and PRK vision correction surgeries to address nearsightedness, farsightedness, and astigmatism.
While both procedures share the same goal, they differ in technique, healing time, and suitability for certain patients. Keep reading to explore the differences between LASIK and PRK and to learn how state-of-the-art technologies like the Pentacam and iDesign® enhance safety and precision in laser eye surgery.
What is the difference between LASIK and PRK?
Both LASIK and PRK involve reshaping the cornea to correct vision. The primary difference lies in how the outer layer of the cornea is addressed. A simple summary of the difference in LASIK vs. PRK is as follows:
LASIK
A thin flap is created on the cornea, reshaped, and then repositioned. This procedure is known for its shorter recovery time and minimal discomfort.
PRK
Instead of creating a flap, the outer layer of the cornea (epithelium) is removed and the cornea is reshaped with the laser. The epithelium then regenerates during the healing process.
While LASIK remains the most popular laser eye surgery due to its quick recovery, PRK is often recommended for people who are not ideal LASIK candidates, such as those with thin or irregular corneas.
What makes someone a better candidate for PRK over LASIK?
Generally speaking, PRK eye surgery offers a safe and effective alternative for patients who are not eligible for LASIK, which may include men and women with:
- Thin corneas
- Irregular corneal shapes
- Active lifestyles or high-risk jobs/environments
- Certain eye health conditions
It's important to note that PRK uses the same advanced laser technology as LASIK, such as the VISX Star laser, to achieve comparable — and sometimes superior — results.
How do Pentacam and iDesign improve laser eye surgery?
At Ophthalmology Associates of the Valley, we utilize advanced diagnostic tools to ensure the safest and most effective outcomes possible for LASIK and PRK. These include:
Pentacam
This multidimensional imaging system maps the cornea in extraordinary detail, helping our team identify patients who are not ideal candidates for LASIK. By assessing corneal thickness and detecting abnormalities, the Pentacam reduces the risk of complications after laser eye surgery, such as corneal ectasia.
iDesign®
This advanced technology maps the eye at a resolution up to five times higher than standard tools, enabling a customized treatment plan. LASIK with iDesign significantly improves precision, minimizes visual aberrations, and increases the likelihood of achieving 20/16 or better vision.
What is the recovery time for PRK vs LASIK?
While both procedures offer life-changing results, the recovery timelines differ somewhat. With LASIK recovery, most patients experience improved vision within 24 hours and can resume daily activities within a few days. The healing time for PRK is longer, however, typically taking 1 – 2 weeks for the epithelium to regenerate. Patients may experience temporary discomfort and light sensitivity during this time.
Although PRK requires a longer recovery period, the visual results are equally impressive and long-lasting. With the subtle differences and nuances of each procedure, it is important to choose a laser eye surgeon who is highly knowledgeable and experienced to ensure the most successful outcome and smoothest experience possible.
