Overview of PRK Surgery: Definition and Purpose
Photorefractive Keratectomy (PRK surgery) is a laser eye procedure designed to correct refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. We understand that considering eye surgery can be daunting. Unlike LASIK, which creates a flap in the cornea, PRK surgery involves the removal of the outer layer, known as the epithelium. This allows an excimer laser to reshape the underlying corneal tissue.
This method, PRK surgery, is particularly beneficial for individuals with thinner corneas or those who may not be suitable candidates for LASIK, as its primary goal is to enhance visual clarity and significantly reduce reliance on glasses or contact lenses. It’s a preferred choice for many seeking lasting vision correction.
Understanding the health of your cornea is essential, especially if you have conditions like Keratoconus, where the cornea thins and develops an abnormal curvature. Symptoms of Keratoconus can include:
- Blurred or double vision
- Light sensitivity
- Difficulties seeing at a distance
If left untreated, it can lead to permanent eye damage. At Northwest Eye, we offer treatment options for Keratoconus, including specially fitted contact lenses or advanced procedures like Corneal Collagen Cross-Linking to help halt its progression, and advancements in surgical tools and techniques have greatly improved the outcomes of PRK surgery.
Many individuals express satisfaction with their vision post-procedure. We know that hearing from others can be reassuring, and expert opinions highlight the benefits of PRK surgery, especially for those who may not qualify for LASIK. This reinforces PRK surgery’s important role in the array of vision correction options available to you.

Step-by-Step Guide to the PRK Procedure
- Consultation and Pre-Surgery Evaluation: We understand that considering PRK surgery can raise many questions and concerns. A comprehensive eye examination is essential before undergoing this procedure. This evaluation assesses your suitability by measuring corneal thickness, refractive error, and overall eye health, ensuring that only candidates who meet specific criteria proceed to surgery. At Northwest Eye, we offer financing options designed to ease your financial worries, facilitating access to essential evaluations and procedures.
- Preparation for Surgery: On the day of your procedure, it’s common to feel a bit anxious. To maintain a sterile environment, please refrain from wearing makeup or lotions around your eyes. Numbing eye drops will be administered to enhance your comfort during the surgery, allowing for a smoother experience.
- Removing the Corneal Epithelium: The surgeon will carefully remove the outer layer of the cornea, known as the epithelium, using either a mechanical method or a laser. This critical step exposes the underlying corneal tissue, which is necessary for the subsequent reshaping process.
- Reshaping the Cornea: Utilizing an excimer laser, the surgeon precisely reshapes the cornea to correct the refractive error. This laser procedure is effective and typically lasts just a few minutes for each eye, customized to your specific needs. As Paul Dondi, program manager of the United States Air Force Academy refractive surgery center, shares, ‘Cadets are always telling me that the possibility of having PRK surgery or LASIK is the reason they came to the academy because it would help them fulfill a lifelong dream of becoming a military pilot.’ This highlights the importance of accessible funding alternatives that enable individuals to pursue their aspirations.
- Post-Procedure Care: After your laser treatment, a bandage contact lens will be placed on your eye to protect it during the initial healing phase. You’ll receive detailed aftercare instructions, including the use of prescribed eye drops to facilitate recovery and ensure optimal healing. At Northwest Eye, our financing programs continue to support you throughout your recovery, ensuring that financial barriers do not hinder your healing process.
Navigating PRK Recovery: Timeline and Care Instructions
After surgery, it’s common to experience some discomfort, light sensitivity, and blurry vision. These sensations are part of the healing process but may also indicate underlying issues, such as uncorrected refractive errors or conditions like cataracts and macular degeneration. We recommend resting and avoiding bright lights to help facilitate your recovery.
The initial healing phase typically lasts 3 to 5 days. During this time, it’s important to use your prescribed drops consistently and wear protective eyewear when outside to safeguard your vision from environmental factors. As Dr. M. Ronan Conlon advises, wearing wraparound sunglasses can be particularly beneficial in protecting your eyes from wind and debris, especially since glare and halos can be more pronounced during this period.
Please remember to attend your follow-up appointments as scheduled. These visits are crucial for monitoring your healing and addressing any concerns you may have. The bandage contact lens is usually removed within a week, allowing for a further assessment of your recovery progress. Be vigilant for any signs of blurred sight, as they may suggest the presence of issues like cataracts or macular degeneration that require expert care.
Complete visual restoration can take several weeks to months. You may notice fluctuations in your vision during this period, which is completely normal as your cornea stabilizes. It’s important to be aware that exposure to UV-B rays can increase the risk of late-onset haze, highlighting the need for proper eye protection.
To ensure a smooth recovery, we encourage you to avoid rubbing your eyes, using makeup, or engaging in strenuous activities for at least a week after surgery. Staying hydrated and adhering to your prescribed medication regimen is crucial for a smooth recovery. Identifying and managing risk factors preoperatively is essential for successful outcomes after PRK surgery. The integration of Mitomycin-C in PRK surgery procedures has been shown to effectively reduce postoperative haze, particularly in cases of high myopia, contributing to improved long-term visual outcomes.
PRK vs. LASIK: Key Differences and Considerations
Both PRK surgery and LASIK are popular refractive surgeries, and we understand that choosing between them can feel overwhelming. It’s important to recognize that these procedures vary greatly in technique and the experiences of individuals.
In PRK surgery, the procedure technique involves removing the outer layer of the cornea, known as the epithelium. In contrast, LASIK involves creating a flap in the cornea. This fundamental difference can influence your recovery and comfort levels. Many individuals find that after PRK surgery, there is typically more post-operative discomfort due to the healing of the epithelium, and we want you to be prepared for that.
The recovery time from PRK surgery generally takes longer than from LASIK. You might experience blurry vision for several days after surgery, while LASIK recipients often notice improvements within hours. This extended recovery period is something to consider, especially if you have time-sensitive needs. We understand that your schedule is important, and we are here to help you navigate this decision.
Suitability: PRK surgery is particularly advised for individuals with thinner corneas or those who engage in contact sports. By opting for PRK surgery, you can eliminate the risk of flap-related complications associated with LASIK, making PRK surgery a safer option for certain individuals. Your safety and comfort are our top priorities.
Post-Operative Discomfort: After PRK surgery, you may experience more discomfort compared to LASIK patients, who typically report less pain. This is largely due to the removal of the epithelium in PRK, which requires time to heal. As Dr. Mark Hansen observes, “Everyone recovers at a different rate, but the unclear sight will lessen as the eye mends.” We want you to feel supported throughout your recovery journey.
Long-Term Outcomes: Both PRK and LASIK boast comparable long-term success rates in sight correction. However, individual experiences can vary based on personal health and healing responses. Recent advancements in PRK surgery techniques have enhanced safety and efficacy, leading to better visual outcomes and reduced complications.
In summary, while both procedures are effective for vision correction, the choice between PRK and LASIK should be guided by your unique circumstances, including corneal thickness, lifestyle, and recovery preferences. Remember, we are here to help you through this process and ensure you make the best decision for your vision.
