Introduction

Photorefractive keratectomy (PRK) is a type of photorefractive keratectomy surgery used to correct refractive errors. It was the first laser vision correction procedure and is still widely used today. PRK surgery reshapes the cornea to help light focus more accurately on the retina, improving vision.

How PRK Works

PRK uses an excimer laser to reshape the cornea by removing a thin layer of tissue. The surgeon first removes the epithelium (the top layer of the cornea) to access the corneal tissue underneath. The laser then reshapes the cornea according to the patient’s specific refractive error. Once the PRK procedure surgery is complete, the epithelium heals naturally over a few days.

Who Is the Right Candidate for PRK?

Eligibility Criteria:

  • Ideal candidates for eye surgery PRK are usually over the age of 18 and have stable vision prescriptions for at least a year.
  • Candidates should not have other significant eye conditions, such as cataracts or glaucoma.

Disqualifying Factors:

  • Individuals with thin corneas, severe dry eye, or corneal diseases may not be suitable candidates.
  • Pregnant or nursing women should postpone the procedure.

Additional Criteria

  • Patients with active lifestyles or careers that may be affected by corneal flap complications (such as athletes and military personnel) may benefit from PRK laser eye surgery.

Preoperative Assessment

Before undergoing PRK, a thorough eye examination is necessary to determine if you are a suitable candidate for the procedure:

  • Comprehensive Eye Examination: Review your medical history and assess your overall eye health.
  • Visual Acuity: Measure your ability to see clearly at different distances.
  • Corneal Thickness: Determine the thickness of your cornea using a device called a pachymeter.
  • Topography and Wavefront Analysis: Map the curvature and surface of your cornea and assess the quality of your vision.
  • Pupil Size: Measure the size of your pupil in different lighting conditions.
  • Intraocular Pressure (IOP) Measurement: Check your eye pressure for glaucoma risk assessment.

Preparing for PRK Surgery

To ensure you are well-prepared for PRK:

Avoid wearing contact lenses for a few days before surgery as recommended by your doctor.

    • Refrain from wearing makeup, lotions, or perfumes on the day of surgery to prevent eye irritation.
    • You will need someone to drive you home after surgery.
    • Have a light meal before surgery to avoid discomfort.

Advances in PRK

Over the years, PRK has seen significant advances thanks to improvements in laser technology and other surgical techniques. These advances have made PRK a safer and more precise procedure:

  • Pupil Tracking: Modern PRK systems often include advanced pupil-tracking technology to ensure that the laser is precisely aligned with the patient’s eye throughout the procedure, even if the eye moves.
  • Cyclotorsion Control Advances: Advanced systems can track the eye’s rotation during the procedure, ensuring precise treatment even if the eye rotates during surgery.
  • Rigid Gas Permeable (RGP) Lenses: These lenses create a smooth surface for light to focus correctly, improving your vision.
  • Excimer Laser Technology: Excimer lasers have evolved to provide faster treatment times and better control of ablation patterns, leading to improved visual outcomes and reduced healing times.

The PRK Procedure

During Surgery:

  • PRK typically takes about 10 to 15 minutes per eye and is performed on an outpatient basis.
  • Anesthetic eye drops are used to numb the eye.
  • The surgeon removes the epithelium and reshapes the cornea using the excimer laser.

Recovery:

  • After the procedure, you may experience some discomfort, such as a gritty sensation or mild irritation.
  • A protective contact lens is placed on your eye to aid in healing.
  • Vision may be blurry initially but typically improves over several days to weeks.
  • Follow your surgeon’s postoperative care instructions carefully to ensure proper healing.

PRK stands for photorefractive keratectomy. It is a type of laser eye surgery that reshapes the cornea to correct refractive errors such as myopia, hyperopia, and astigmatism.

PRK usually takes about 10 to 15 minutes per eye.

Yes, PRK is a safe and effective procedure that has been performed for many years. It is considered a proven method for vision correction.

Recovery time varies for each individual, but most patients begin to see improvement within a few days. Complete recovery may take a few weeks.

Some patients may experience mild discomfort or irritation during the recovery period, but it usually resolves within a few days.

Most patients can return to work and normal activities within a few days, depending on their healing progress. Avoid strenuous activities or swimming for a few weeks.

Most patients can return to work within a few days to a week after PRK, depending on their healing progress and the nature of their job. Your surgeon will provide personalized guidance on when it’s safe to return to work.

Customied PRK, also known as wavefront-guided PRK or Contoura, uses advanced mapping technology to create a personalized treatment plan based on your unique corneal topography and optical aberrations. This allows for precise and targeted laser ablation, potentially resulting in improved visual outcomes.

Trans PRK is a no-touch version of PRK where the epithelium and the underlying corneal tissue are ablated simultaneously using an excimer laser. This procedure can provide smoother and more comfortable healing.

Both PRK and LASIK are laser eye surgery procedures that reshape the cornea to correct refractive errors. The primary difference lies in how the procedures are performed. In LASIK, a corneal flap is created and then the underlying tissue is reshaped with the laser. In PRK, the top layer of the cornea (epithelium) is removed, and the laser reshapes the exposed cornea. PRK is better suited for individuals with thinner corneas or those with active lifestyles.

PRK reshapes the cornea by removing the epithelium and applying the laser directly to the corneal tissue. In SMILE (Small Incision Lenticule Extraction), a small incision is made in the cornea, and a tiny lenticule is removed to correct refractive errors. SMILE is a more recent procedure and may offer a faster recovery time, but PRK has a longer history of safety and effectiveness.

SILK (Sub-Bowman’s Keratomileusis) is a newer procedure that uses a femtosecond laser to create a sub-Bowman’s lenticule that is then extracted to correct refractive errors. PRK and SILK differ in the methods used to reshape the cornea, with PRK applying the laser directly to the cornea’s surface and SILK focusing on a deeper layer beneath Bowman’s membrane.

PRK eye surgery is the same as PRK laser eye surgery, where an excimer laser is used to reshape the cornea to correct refractive errors.

The cost of PRK eye surgery in India can vary depending on the clinic, the surgeon’s experience, and the specific technology used. It’s best to consult with your chosen clinic for an accurate cost estimate.

Recovery time for PRK eye surgery can vary, but most patients begin to see improvement within a few days. Complete recovery may take a few weeks.

PRK laser eye surgery is another term for photorefractive keratectomy, a laser surgery that reshapes the cornea to correct refractive errors.

The cost of PRK eye surgery can vary depending on the surgeon, clinic, and location. It’s important to discuss costs and any potential financing options with your chosen clinic.

PRK surgery price can vary depending on several factors, including the surgeon, the clinic, and the technology used. Make sure to discuss costs and possible financing options with your chosen clinic.
