Laser Vision Correction in Orange County: LASIK and PRK with Dr. Audrey Tai

Reviewed by Dr. Audrey Tai, board-certified, fellowship-trained ophthalmologist — Athena Eye Care, Mission Viejo, Orange County, CA

Quick answer: Laser Vision Correction (LVC) is a category of outpatient procedures that reshape the cornea using an excimer laser to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism — providing a long-lasting alternative to glasses and contact lenses. Dr. Tai offers two leading LVC options: all-laser bladeless WaveFront-Guided iLASIK (rapid recovery, excellent visual outcomes) and WaveFront-Guided PRK (an effective alternative for patients with thin corneas or specific occupational requirements).

What Does Laser Vision Correction Treat?

Laser Vision Correction surgeries are designed to correct refractive errors — the optical imperfections that cause blurred vision — providing a long-lasting alternative to eyeglasses or contact lenses. LVC is typically recommended for adults who do not have cataracts or significant presbyopia and who have stable vision prescriptions.

Laser Vision Correction can treat the following refractive errors:

• Myopia (nearsightedness) — Difficulty seeing clearly at distance. Near vision is usually clearer in myopic patients when they are young, before they develop the need for reading glasses.
• Hyperopia (farsightedness) — Difficulty seeing clearly up close, more so than at distance. Patients with hyperopia typically need reading glasses earlier than age 40.
• Astigmatism — Vision is blurry and shadowy at all distances because the cornea is more oblong (football-shaped) than round (basketball-shaped).

For patients with cataracts or significant age-related near-vision loss, cataract surgery or refractive lens exchange (RLE) may be more appropriate. Dr. Tai will help determine which procedure best fits your eyes and goals.

The Two Main Types of Laser Vision Correction

LASIK (Laser-Assisted In Situ Keratomileusis)

LASIK is the most commonly performed laser vision correction surgery in the world. Its excellent visual outcomes, strong safety profile, and rapid vision recovery make LASIK the most popular LVC procedure performed today.

All-Laser Bladeless WaveFront-Guided iLASIK with Dr. Tai

Dr. Tai offers all-laser bladeless WaveFront-Guided iLASIK, the most advanced and customized LASIK approach available today. The procedure uses three FDA-approved technologies in sequence:

1. 3D Corneal Mapping with iDesign WaveScan or CustomVue. Before surgery, Dr. Tai obtains a high-resolution 3D map of the surface of your eye using either the iDesign 2.0 or CustomVue system (the choice depends on your specific prescription). This creates a fully customized treatment plan unique to your eye.
2. IntraLase iFS Femtosecond Laser. Dr. Tai uses this all-laser, bladeless system to create a thin, precise corneal flap — without using a mechanical microkeratome blade. This is the "all-laser" component that distinguishes modern bladeless iLASIK from older LASIK techniques.
3. VISX STAR S4 IR Excimer Laser. Once the flap is created, Dr. Tai uses this advanced excimer laser to perform the WaveFront-guided customized correction of your prescription, reshaping the corneal tissue with micron-level precision. The thin corneal flap is then carefully repositioned to heal naturally.

The iDesign 2.0 and CustomVue WaveFront-guided systems Dr. Tai uses provide the most advanced and personalized LASIK treatment available on the market — designed to address not only standard refractive errors but also the subtle higher-order optical aberrations unique to each individual eye.

PRK (Photorefractive Keratectomy)

PRK is a Laser Vision Correction surgery that serves as an effective alternative for patients who aren't candidates for LASIK.

PRK is commonly chosen for patients who have:

• Thinner corneas (where flap creation isn't safe)
• Mild corneal scarring
• Certain occupational requirements — military service members, law enforcement officers, firefighters, and athletes in contact sports often prefer PRK

Compared to LASIK, PRK does not involve creating a corneal flap. Instead, the superficial layer of the cornea (the epithelium) is gently removed before the excimer laser treatment, and a bandage contact lens is placed on the eye after the procedure to promote healing.

When compared to LASIK, PRK is usually associated with slightly more discomfort and a longer recovery period — but multiple peer-reviewed studies have shown the final visual outcome is equivalent between LASIK and PRK.

Dr. Tai offers WaveFront-guided customized PRK using the same VISX STAR S4 IR excimer laser used in iLASIK, providing the same level of precision and personalization for patients who choose this option.

LASIK vs. PRK: Which Is Right for You?

LASIK — Rapid recovery, no discomfort

• Corneal flap created with femtosecond laser
• Most patients see well within 24 hours
• Minimal discomfort
• Best for: most refractive candidates with adequate corneal thickness

PRK — Slower recovery, equivalent final outcome

• No corneal flap created
• Functional vision returns over 1–2 weeks; best vision over weeks
• Mild to moderate discomfort first few days
• Best for: thin corneas, contact-sport athletes, military, mild scarring

Both procedures deliver equivalent final visual outcomes — the right choice depends on your corneal thickness, prescription, occupation, lifestyle, and personal preferences. Dr. Tai will discuss both options in detail at your consultation.

Frequently Asked Questions About Laser Vision Correction

Am I a candidate for LASIK or PRK?

Most adults with stable refractive errors and healthy eyes are candidates. Disqualifying factors can include thin corneas, certain corneal diseases (like keratoconus), uncontrolled dry eye, unstable prescriptions, and certain systemic conditions. A comprehensive consultation is the only way to know for sure.

How long does LASIK take?

The procedure itself takes about 15 minutes for both eyes. Most patients are at the surgery center for about 2 hours including pre-op preparation and post-op monitoring.

Is LASIK painful?

No. The eye is numbed with anesthetic drops and patients typically feel only pressure during the procedure. Some patients experience mild discomfort or a gritty sensation for a few hours afterward.

How soon will I see clearly after LASIK?

Most patients see well enough to drive themselves to their day-after follow-up appointment. Vision continues to sharpen and stabilize over the following weeks.

How soon will I see clearly after PRK?

PRK recovery is slower than LASIK. Functional vision typically returns within 1–2 weeks, with continued improvement over several weeks to a few months.

Is laser vision correction permanent?

The corneal reshaping is permanent. However, your vision can still change over time due to natural aging — particularly the development of presbyopia in your 40s and cataracts later in life.

Will I still need reading glasses after LASIK?

LASIK and PRK do not prevent presbyopia. Most patients corrected for distance vision will eventually need reading glasses as they enter their 40s, though some choose monovision LASIK to delay this.

Does insurance cover laser vision correction?

Generally no — LASIK and PRK are elective procedures. Many patients use HSA/FSA funds or financing options.

Schedule Your Laser Vision Correction Consultation

The best way to determine whether LASIK, PRK, or another vision correction option is right for you is a personalized consultation. Dr. Tai will measure your eyes precisely, discuss your goals and lifestyle, and explain the risks, benefits, and recovery expectations of every recommended procedure.
