Refractive surgery includes a range of vision correction procedures that reshape the cornea to improve how light focuses on the retina—helping patients see clearly without glasses or contacts. At NVISION Eye Centers, Dr. Sheri Rowen, MD, performs advanced refractive treatments in Newport Beach, California, for patients across Orange County and nearby areas such as Fullerton.
As a board-certified ophthalmologist and experienced refractive surgeon, Dr. Rowen performs LASIK, PRK, and Advanced Surface Ablation (ASA) procedures. Each treatment is carefully selected based on the patient’s eye health, corneal thickness, prescription, and visual goals.
What Is Refractive Surgery?
Refractive surgery refers to procedures that correct common vision problems, including:
- Myopia (nearsightedness)
- Hyperopia (farsightedness)
- Astigmatism
- Presbyopia (age-related loss of near focus)
These treatments reshape the cornea to improve focus and clarity without relying on external lenses. While LASIK is the most recognized option, Dr. Rowen also performs surface-based procedures such as PRK and ASA, which are ideal alternatives for patients who are not candidates for traditional LASIK.
Each procedure is performed using advanced excimer laser technology, ensuring precise and predictable results.
Advanced Surface Ablation (ASA)
Advanced Surface Ablation (ASA) is a laser vision correction procedure that reshapes the cornea without creating a flap. Dr. Rowen gently removes the eye’s outermost epithelial layer to access the corneal surface, then uses an excimer laser to correct the refractive error.
The treatment typically takes just a few minutes per eye. A soft contact lens is placed afterward to protect the surface while it heals, and most patients notice visual improvement within one to four weeks. ASA is especially suitable for patients with thinner corneas or those who prefer a flap-free procedure.
Photorefractive Keratectomy (PRK)
PRK is another surface-based laser procedure that improves vision by reshaping the outer layer of the cornea. Like ASA, it eliminates the need for a corneal flap, making it an excellent choice for patients with certain corneal conditions, such as scarring or dystrophies, that make LASIK unsuitable.
During PRK, Dr. Rowen removes the epithelium—the thin surface layer of the cornea—and uses the excimer laser to precisely sculpt its curvature. A contact lens is applied after treatment to promote healing. Most patients experience some blurriness during the initial recovery phase, but vision continues to improve as the epithelium regenerates over several days.
PRK offers excellent long-term results, with the same visual clarity and stability expected from LASIK once healing is complete.
Epi-LASIK
Epi-LASIK bridges the gap between LASIK and PRK. The procedure separates the thin epithelial layer using a fine oscillating instrument rather than alcohol or a laser. This technique reduces discomfort and allows for faster healing compared to traditional PRK, while still avoiding the need for a corneal flap.
Dr. Rowen often recommends Epi-LASIK for patients with active lifestyles, thinner corneas, or dry eyes who want a safe, effective way to reduce dependence on corrective lenses.
