Are you struggling to decide between PRK and LASIK vision correction surgery? Both are popular eye surgery options designed to improve vision, but they differ in approach, recovery time, and ideal candidates. Understanding these differences can help you make an informed choice.
What is PRK?
PRK vision correction (Photorefractive Keratectomy) involves removing the outer layer of the cornea and reshaping the underlying tissue with a laser. This procedure doesn’t require cutting a corneal flap, making it a suitable option for patients with thinner corneas or those who may not be ideal LASIK candidates.
What is LASIK?
LASIK vision correction (Laser-Assisted In Situ Keratomileusis) is the most popular laser eye surgery, accounting for about 96% of all laser vision corrections. LASIK involves creating a thin flap in the cornea, reshaping the corneal tissue underneath, and then repositioning the flap. It offers a shorter recovery time and minimal discomfort post-surgery.
Facts of LASIK and PRK
Who is the Right Candidate?
PRK vision correction surgery is best for you if you:
● Are over 18 and have a stable eyeglass prescription for at least one year.
● Have thin corneas, irregular astigmatism, or have had prior eye surgery.
● Have no abnormalities of the cornea or external eye.
● Do not have any autoimmune diseases.
● Engage in contact sports where there’s a risk of eye injury.
● Are not pregnant or nursing at the time of surgery.
● Are not consuming any medications that interfere with the surgical and healing process.
LASIK vision correction surgery is best for you if you:
● Are at least 18 years old.
● Have vision that has stayed consistent for at least one year.
● Do not suffer from chronic dry eye.
● Have a cornea thick enough to create a corneal flap.
● Don’t engage in sports that involve direct eye contact.
● Have not been very successful with contact lenses.
● Are not pregnant or breastfeeding at the time of surgery.
Pre-Operative Instructions
Both vision correction surgeries require similar preparation. Here are some key steps:
1. Have a thorough dilated eye exam to determine whether you are a good candidate.
2. Discuss your payment options.
3. Avoid eye make-up 3 days before LASIK treatment.
4. Perfumes/cologne/deodorants should not be used on the day of surgery.
5. Put the antibiotic eye drops in both eyes as per the doctor’s recommendations.
6. Stop wearing contact lenses as instructed by your doctor.
7. Avoid smoking or drinking alcohol, as these can interfere with healing.
The Procedure
For PRK:
1. Numbing drops are placed in the eye to soften the cornea.
2. The surface of the cornea is smoothed by the surgeon with a special surgical instrument.
3. An excimer laser is then used to precisely reshape the curvature of the cornea’s surface.
4. A soft contact lens is placed on the cornea to help protect the eye as it heals.
For LASIK:
1. A corneal flap is created with a microkeratome.
2. The corneal flap is folded back.
3. The excimer laser beam reshapes the cornea.
4. The corneal flap is repositioned, naturally adhering without stitches.
Post-Operative Care
Following either PRK or LASIK vision correction surgeries, it’s important to follow your doctor’s aftercare instructions:
● Avoid rubbing your eyes for at least a month after the surgery.
● Don’t drive till your doctor approves.
● Wear the eye shield/goggles that you will receive in your post-operative kit when sleeping for the next week after surgery.
● Avoid swimming or any such water contact for the next 1 week after surgery.
● No eye makeup for at least a week after surgery.
● No exercise for 2 days after surgery.
● Use prescribed eye drops to prevent infection and keep your eyes lubricated.
● Wear protective eyewear as recommended.
Key Points to Consider
Recovery Differences:
● PRK vision correction surgery generally involves a longer recovery with more post-operative discomfort, as the cornea’s surface layer takes time to heal.
● LASIK vision correction surgery patients recover faster, with most achieving 20/20 vision within 24 hours.
Final Thoughts
PRK and LASIK are effective options for vision correction, each with unique advantages and considerations. If you’re unsure which procedure is right for you and live in Fresno or Madera, consider consulting with a LASIK specialist to discuss your needs, lifestyle, and eye health. By making an informed decision with the guidance of a local eye care professional, you’ll be well on your way to clearer vision and greater confidence.
