PRK Eye Surgery Procedure Case Study

September 22, 2021

Myopia case prevention in adults is often associated with LASIK and PRK (Photorefractive Keratectomy) surgeries. Both LASIK and PRK use a LASER to remove a microscopic amount of tissue from specific areas on the cornea. By removing tissue, the light that passes through the eye is redirected to correctly hit the retina. Although exceedingly rare, some patients may experience myopic regression where an additional procedure is needed. However, a vast majority of patients go decades enjoying their LASER vision!

We’ve put together a myopia case study to help exemplify its powerful results and the patient experience process.

PRK Patient Information and Diagnosis

Our PRK patient Margo is a 27-year-old account manager at a digital marketing agency here in Chicago. As an active person and amateur dancer, Margo was frustrated when her vision began to decline around the age of 17. During this time, Margo was reading heavily to prepare for her university entrance exams. Her vision continued to decline year after year.

Once her vision was stable, and after mulling it over for 3 years, Margo was ready to make a change to her vision. As luck would have it, Margo was assigned to be the Kraff Eye Institute’s account manager to help with our digital marketing. According to Margo, she immediately knew she was in great hands with Dr. Colman Kraff. He has performed over 70,000 laser vision correction procedures and is considered a pioneer in the industry.

Prior to surgery Margo was found to have mild myopia in both eyes. She had a refractive error of -2.75 in her right eye and a -3.25 in her left. Both eyes were found to have a small amount of astigmatism as well, measuring at +.50. Margo’s uncorrected vision was found to be 20/400 in both eyes.

PRK Procedure and Treatment Recommendations

Margo’s first step on her journey to better vision started with her initial consultation. At this appointment, screening measurements were performed to get a better idea as to whether or not surgery was going to be a safe and effective treatment option for her. After reviewing both LASIK and PRK surgery with one of our Refractive Consultants, Margo met with Dr. Kraff who reviewed all her measurements and answered all her questions. It was determined at this appointment that Margo did fall within the necessary perimeters to safely move forward with LASER eye surgery.

A corneal topography, which is a picture of the surface of the eye, showed that Margo’s corneas were asymmetric. As a result, it was determined that a PRK treatment would be the safest option for her. PRK for myopia is a highly effective surgery which allows patients to be less dependent on glasses and contact lenses. PRK eye surgery for nearsightedness is just as effective as LASIK giving patients the same visual outcomes.

During Margo’s surgery, topical numbing drops were administered to create a pain-free procedure. To help keep Margo from blinking, a small lid speculum was used which gently held her eyelids open. For Margo’s surgery, an amoils brush was used to gently remove her epithelium. The epithelium is the surface layer of the cornea and is some of the fastest regenerative tissue that we have in our bodies. Once removed, the LASER was used to reshape her cornea. The laser treatment was a matter of seconds and she felt no discomfort as the laser treating. Her treatment was customized based on her specific measurements which were gathered utilizing the iDesign 2.0 software. This software is the most advanced and precise way of performing LASER eye surgery today.

Upon completion, a soft bandage contact lens was placed on the eye and the lid speculum was removed. The same process was then repeated for the second eye. After both eyes were treated Margo was brought into a post-op room where all her instructions for recovery were gone over in detail.

PRK Follow Up Appointments

The PRK procedure recovery is slightly longer than that of a LASIK procedure. Margo was instructed to avoid normal activities, including work, for the first 48 to 72 hours. Margo, like most PRK patients, found she had a highly functioning vision during that time, but avoiding reading and extensive computer use helped to expedite the healing process. Margo was seen for a handful of PRK follow-up visits immediately after her procedure. After about 3 days, the surface of her cornea had healed enough that the soft bandage contact lens was removed and she was given the ok to return to work and using a computer. Margo went from having the uncorrected vision of 20/400 to ultimately seeing 20/20 following her PRK procedure.

PRK Procedure Results

Following her eye surgery for nearsightedness, Margo is thrilled with her results and she’s able to enjoy a happier, more focused life. She went from declining vision to the “best vision she’s had in her life”.

If you want to experience results like Margo, “Dr. Kraff at the Kraff Eye Institute is an incredible surgeon to consider”.
