3 Types of Refractive Eye Surgery You Should Know
Refractive eye surgery corrects vision problems like nearsightedness, farsightedness, and astigmatism by changing how light focuses on the retina. The three most common types are LASIK, PRK, and EVO Implantable Collamer Lens (ICL) surgery. Each option uses a different method to improve vision and reduce dependence on glasses or contact lenses. The right procedure depends on your corneal thickness, prescription strength, and overall eye health, which can only be determined through a comprehensive eye exam at Dougherty Laser Vision (DLV).
Quick Takeaways
- LASIK, PRK, and ICL are the main refractive surgery options.
- All procedures aim to correct blurry vision caused by refractive error.
- Not every patient qualifies for every type of surgery.
- A full eye evaluation determines the safest option.
- DLV provides customized vision correction in Ventura County and Los Angeles County.
What is refractive eye surgery?
Refractive eye surgery is a group of procedures that correct how the eye bends light. When light does not focus properly on the retina, vision becomes blurry. This condition is called a refractive error and includes nearsightedness, farsightedness, and astigmatism. According to the American Academy of Ophthalmology, these errors are among the most common reasons people need glasses or contacts.
At Dougherty Laser Vision (DLV), the clinical team uses advanced diagnostic imaging to map the cornea and determine which surgical option matches each patient’s eye structure and prescription.
What are the three main types of refractive surgery?
LASIK eye surgery
LASIK reshapes the cornea using a laser after creating a thin flap on the eye surface. It treats nearsightedness, farsightedness, and astigmatism. Many patients experience clearer vision within days after treatment.
PRK laser eye surgery
PRK reshapes the cornea without creating a flap. The surface layer heals naturally after laser treatment. It is often recommended for patients with thinner corneas or active lifestyles.
EVO Implantable Collamer Lens (ICL)
ICL surgery places a soft lens inside the eye without removing corneal tissue. It is commonly used for patients with higher prescriptions or those not eligible for laser procedures.
Who is a candidate for refractive eye surgery?
Good candidates typically have stable vision for at least one year, healthy corneas, and no uncontrolled eye disease. Severe dry eye, pregnancy, or certain corneal conditions may affect eligibility. A detailed eye exam at Dougherty Laser Vision (DLV) determines whether LASIK, PRK, or ICL is the safest option.
If you live in Ventura County or Los Angeles County, you can schedule an evaluation with DLV to determine which procedure fits your eyes best.
