Is Presbyopic Implant Surgery (PIE) Better Than PRK? Understanding the Difference
As people reach their 40s or 50s, reading small print, menus, or phone screens can become difficult — a common sign of presbyopia, or age-related near vision loss. For many years, PRK (Photorefractive Keratectomy) was one of the most trusted procedures to correct refractive errors. However, modern innovations like the Presbyopic Implant in Eye (PIE) now offer a more advanced and long-lasting solution, especially for patients who want freedom from reading glasses and bifocals.
At Khanna Vision Institute, Dr. Rajesh Khanna specializes in both PRK and PIE, helping patients choose the procedure that best suits their eyes, age, and lifestyle. This article explains the difference between the two techniques and why PIE is becoming a preferred option for those over 40.
Understanding PRK
PRK (Photorefractive Keratectomy) was one of the first types of laser eye surgery, even before LASIK. It corrects vision by reshaping the cornea using an excimer laser. Instead of creating a flap like LASIK, PRK removes the outermost corneal layer (epithelium) to expose the surface for reshaping.
PRK is particularly useful for patients with thinner corneas or those who may not qualify for LASIK. It’s often used to treat myopia, hyperopia, and astigmatism.
Advantages of PRK include no corneal flap, suitability for patients with thin corneas, and long-lasting results. Limitations include longer recovery time, mild discomfort, and no correction for presbyopia.
What Is Presbyopic Implant in Eye (PIE)
The Presbyopic Implant in Eye (PIE) is a modern and minimally invasive solution designed specifically to restore both near and distance vision. Instead of reshaping the cornea, PIE involves implanting a small intraocular lens (IOL) inside the eye, similar to cataract surgery — but for people who don’t yet have cataracts.
The PIE procedure replaces the aging natural lens with an advanced multifocal or small- aperture lens, allowing the eye to focus at different distances naturally.
Benefits include restoration of both near and distance vision, painless and quick procedure, and prevention of future cataracts.
PIE vs. PRK: The Key Differences
PIE restores near and distance vision, while PRK primarily improves distance vision. PRK involves corneal reshaping, while PIE replaces the natural lens with an advanced one. PIE recovery is faster, virtually painless, and eliminates future cataracts, whereas PRK has a longer recovery and doesn’t address presbyopia.
Who Is the Right Candidate for PIE
You may be an ideal candidate for Presbyopic Implant Surgery if you are over 40, want freedom from reading glasses, have healthy eyes, and are not eligible for LASIK or PRK due to thin corneas. During your evaluation, Dr. Khanna performs advanced eye measurements to recommend the right implant type for your vision goals.
The Technology Behind PIE
Khanna Vision Institute uses cutting-edge lens technologies like IC-8 Apthera Small Aperture IOL, Multifocal and Trifocal Lenses, and Toric IOLs for astigmatism correction. Dr. Khanna customizes each lens choice based on lifestyle, visual demands, and eye anatomy.
Recovery and Results
After PIE surgery, most patients notice clearer vision the next day. Mild sensitivity may occur but fades quickly. Unlike PRK, which requires corneal surface healing, PIE recovery is almost immediate. The artificial lens ensures permanent, age-proof vision.
Why PIE Is Better for Patients Over 40
While PRK remains ideal for younger patients, PIE offers a long-term solution for older adults facing both distance and near vision challenges. It restores full-range vision and prevents cataracts, making it a smarter, age-proof choice.
The Khanna Vision Institute Advantage
Dr. Khanna’s expertise and technology ensure personalized, precise, and safe results. Patients benefit from advanced diagnostics, personalized planning, and compassionate care throughout the process.
Final Thoughts
When comparing PIE vs. PRK, the difference lies in personalization and purpose. PRK reshapes the cornea for younger patients, while PIE restores full-range vision for those with presbyopia. If you’re over 40 and want youthful, clear vision again, schedule a consultation with Dr. Rajesh Khanna at Khanna Vision Institute.
