Prk Vs Lasik Military?

For those serving in the military, vision is more than just a matter of convenience—it’s integral to personal safety, mission success, and the well-being of the team. 

The demands of this career make glasses and contacts impractical and even hazardous in the field. Glasses can dislodge, fog up, or get lost, posing risks to military members and teams. They can also interfere with military equipment like night vision goggles, protective eyewear, and specialised helmets. Contact lenses are prohibited in deployed conditions due to infection risks.

Enter laser vision correction surgery—the promise of clear eyesight without the hindrance of corrective lenses. But when it comes to choosing the right procedure, whether PRK (photorefractive keratectomy) or LASIK (laser-assisted in situ keratomileusis), military personnel have unique factors to weigh.

In this post, we’ll explore the differences between PRK and LASIK, specifically tailored to the needs and considerations of those in the military. By understanding these distinctions, military members can make an informed decision aligned with their professional responsibilities and lifestyle.


Understanding PRK and LASIK

PRK and LASIK have become go-to choices for individuals seeking freedom from glasses and contacts. Both procedures utilise cutting-edge laser technology to correct vision, yet they differ significantly in approach:

  • PRK involves the removal of the cornea’s outer layer to allow excimer laser reshaping of the underlying tissue. Post-surgery, the epithelium regenerates naturally.
  • LASIK, meanwhile, creates a flap in the cornea using either a femtosecond laser or a microkeratome, which is lifted to allow the excimer laser to sculpt the corneal tissue beneath. The flap is subsequently repositioned and allowed to heal.


Both have their merits, but the military lifestyle demands a closer look at the implications of each.


Key Considerations for Military Personnel

Recovery Time

For the active military member, downtime is a precious commodity. 

While PRK boasts impressive long-term results, the recovery period is notably longer (with complete healing taking up to 3 months) than LASIK (full recovery typically occurring within a few weeks to a month), potentially limiting immediate availability for duty. 

LASIK’s rapid recovery timeline is a considerable advantage here, affording minimal interruption to military obligations.


Risk of Flap Dislocation

LASIK’s corneal flap presents a vulnerability—a blow or trauma to the eye could dislocate it, complicating healing and potentially necessitating further medical intervention. Additionally, it can trap debris underneath the flap. Such risks are critical for military personnel where physical confrontation during training or combat situations or exposure to harsh environments is the norm. 

PRK, sans flap, emerges as the safer option regarding durability and maintenance under duress.


Long-Term Stability

In professions where enduring harsh conditions is routine, PRK demonstrates the potential for superior long-term durability and reduced susceptibility to complications. This includes a lower risk of enduring issues like night vision impairments and dry eyes. 

In contrast, LASIK involves creating a flap in the cornea’s top layer (epithelium). This flap can lead to light scattering upon entering the eye, resulting in glare or halos, particularly problematic during nighttime. Additionally, LASIK affects corneal nerves, leading to reduced post-surgery blinking, potentially causing persistent dry eye sensations.

For military personnel facing unpredictable circumstances, stability is crucial. Night vision issues and dry eyes pose significant risks for service members and their units, especially during tasks like flying, sniping, spotting, or leading missions – particularly under low-light conditions.


Patient Comfort

It’s not all about durability, though—comfort plays a role too. 

The initial discomfort and pain following PRK aren’t negligible and can become a real consideration for those who must be ready to serve at a moment’s notice. LASIK, on the other hand, offers a more comfortable recovery period due to the minimal disruption of the corneal epithelium.


Corneal Thickness

Corneal anatomy is a factor with no room for compromise. 

Lasers require sufficient thickness for safe application, placing PRK in the lead for those with thinner corneas after a thorough medical evaluation because it removes less corneal tissue compared to LASIK.


Informed Decision-Making

Choosing between PRK and LASIK for military personnel involves a personalised assessment. Key factors to discuss with your ophthalmologist include:

  • Military Role: Consider your job’s physical demands and associated risks. If your role involves high eye injury risk, PRK may be preferred due to the reduced risk of flap dislocation. Address this concern with your ophthalmologist to understand its impact.
  • Healing Tolerance: PRK’s longer recovery time requires higher discomfort tolerance and may result in blurred vision. If a quick return to optimal vision is crucial for your duties, LASIK’s faster recovery could be more suitable.
  • Corneal Thickness: Your ophthalmologist will assess corneal thickness for procedure safety. With a thin cornea, PRK might be the sole option as it removes less tissue.
  • Overall Health: Certain medical conditions can affect procedure candidacy. Provide your complete medical history for a thorough evaluation.
  • Personal Preferences: PRK and LASIK both offer great vision correction. Consider comfort levels with recovery processes and address concerns with your doctor.


The Right Correction Path

For our military personnel, the pursuit of refined vision through PRK or LASIK isn’t merely a lifestyle improvement; it’s an investment in both operational efficacy and personal safety. Considering the demands of service and the potential impact on functionality within their roles, the decision between these two methods of corrective surgery cannot be taken lightly. 

Whether through the careful elimination of corneal tissue in PRK or the quick-healing precision of LASIK, the path to unobstructed vision is a strategic one. Furthermore, it’s a decision underscored by the understanding that in the theatre of operations, clear sight equates to readiness—and readiness, ultimately, could make all the difference.

Remember: If you’re considering PRK or LASIK and you’re in the military, the most critical step is to consult with your medical provider and commanding officers to ensure the choice aligns with your career trajectory and immediate duties.

Clear vision is imperative; choosing how you achieve it is your mission today.
