Photorefractive Keratectomy (PRK): A Minimally Invasive Vision Correction Method

 Photorefractive Keratectomy (PRK) is a highly effective, minimally invasive procedure designed to reshape the cornea, thereby reducing or eliminating the need for glasses. While often compared to LASIK surgery, PRK is a unique approach that provides similar outcomes with distinct differences in the surgical process and recovery. We utilize advanced computerized excimer lasers to perform this procedure, ensuring precision and safety for our patients.

The PRK Procedure

PRK involves the gentle removal of a thin layer of tissue from the corneal surface using a state-of-the-art excimer laser. This laser reshapes the cornea, allowing it to better focus light onto the retina, which improves vision clarity. Unlike LASIK, which involves creating a flap in the cornea, PRK directly targets the surface layer, making it an excellent option for patients with thinner corneas or other considerations that may not make them ideal LASIK candidates.

The entire PRK treatment typically takes between 10 to 20 seconds, during which the laser is meticulously guided by a computer to ensure precise tissue removal. This rapid and accurate process allows patients to experience minimal discomfort during the procedure itself.

Post-Procedure Care and Recovery

After the PRK treatment, a protective contact lens is placed on the cornea to keep the patient comfortable as the epithelial layer heals. This lens acts as a bandage, aiding in the healing process and protecting the eye during the initial recovery period. Most patients experience some level of discomfort, such as mild irritation or a sensation similar to having an eyelash in the eye, but this is usually well-managed with prescribed medications.

The healing process for the epithelial layer typically takes 3 to 5 days. During this time, patients may notice that their vision is somewhat compromised, appearing hazy or blurred. The contact lens, while slightly bothersome, plays a crucial role in ensuring the eye heals correctly.

Once the cornea has healed sufficiently, and the contact lens is removed, patients will begin to notice significant improvements in their vision. As the cornea continues to smooth and settle, vision clarity will continue to enhance, often resulting in a substantial reduction or complete elimination of the need for corrective lenses.

Benefits of PRK

PRK offers several benefits, including:

  • Suitability for Patients with Thin Corneas: Unlike LASIK, PRK does not require the creation of a corneal flap, making it an ideal choice for individuals with thin or irregular corneas.

  • Minimally Invasive Approach: PRK involves minimal intervention, focusing solely on the corneal surface, which can result in fewer complications related to flap creation.

  • Proven Track Record: PRK has a long history of providing excellent visual outcomes and is particularly beneficial for patients with specific corneal characteristics.

At MAIDA CustomVision, we are committed to providing the highest quality of care using state-of-the-art technology. Our expert team ensures that each PRK procedure is tailored to meet the unique needs of our patients, helping them achieve clearer vision and a better quality of life.

Lens-Based Refractive Surgery: Exploring Advanced Options for Vision Correction

Image
  For individuals who may not be ideal candidates for traditional laser refractive surgeries like LASIK and PRK, lens-based refractive surgery presents a valuable alternative. Our experienced team, led by some of the best LASIK surgeons in Jacksonville , provides cutting-edge solutions in this field, ensuring optimal outcomes for a wide range of patients. One of the most common types of lens-based refractive surgery is modern cataract surgery, which involves replacing a cloudy lens with an intraocular lens (IOL). This procedure can also be performed preemptively to address refractive errors before cataracts develop, a process known as refractive lens exchange (RLE). Depending on the type of IOL used, RLE can effectively treat conditions such as myopia, hyperopia, astigmatism, and presbyopia. Premium Lens Implants While standard monofocal IOLs improve vision at a single distance, typically far, many patients find they still need glasses for near and intermediate tasks after cataract sur
