LASIK Questions

Beverly Hills, Rancho Cucamonga, Burbank

What is LASIK?

LASIK (laser assisted in-situ keratomileusis) is a form of laser vision correction where a thin flap is created in the cornea exposing the stromal bed where the laser is delivered. Following the laser treatment, the corneal flap is repositioned. The active pump in the cornea helps to keep the flap in position; therefore, no stitches are needed.  Most people notice immediate results and are able to return to work the following day.

What is PRK?

PRK (Photorefractive keratectomy) also referred to as surface ablation uses the excimer laser to reshape the cornea after the epithelial (surface) cells are removed . Like LASIK, PRK can correct nearsightedness, farsightedness, and astigmatism. No flap is created during PRK therefore the reshaping of the cornea takes place at a more superficial level. In some patients, due to individual anatomic variations, PRK may be the procedure of choice for safety reasons. PRK patients typically have a longer recovery time and may experience more post-operative discomfort.

Am I a candidate for LASIK and PRK?

The only way to tell for sure if you are a candidate for LASIK or PRK is to have a detailed eye exam, included in our complimentary LASIK consultation. In general, you should:

  • Be at least 18 years of age
  • Be in good general health
  • Have no condition affecting the eyes, including eye infections and pregnancy
  • Have a prescription that is stable for at least one year

Other qualifications (such as the shape of your cornea and the type of visual errors) may make you a better candidate for wavefront LASIK or PRK.

How long does LASIK take?

The LASIK procedure only takes a few minutes for each eye. Generally less than 20 minutes for both eyes. You should count on being at our office for about an hour.

Does LASIK hurt?

Generally not. Numbing drops are used during the procedure, and if you feel discomfort later, over-the-counter medication is typically adequate.

When will I see improvement in my vision?

Most people see improvement from LASIK right away. It may take several months before your vision completely stabilizes.

Are there complications associated with LASIK?

Yes as with any surgical procedure complications are possible. Minor side effects like temporary dry eyes affect many patients. In some cases under-correction, over-correction, or regression may occur. This may necessitate a touch-up.  Infection and inflammation are very rare. Night vision symptoms such as glare, haloes, starbursts, and ghosting are common early on but improve and subside. Long-term complications of LASIK like dry eyes or night vision problems are more rare.

I have heard about bladeless LASIK? What’s the difference? Is it better?

In LASIK, the reshaping is done in the middle of the cornea. To access this part of the cornea, a flap is created and folded aside. Traditionally, the flap is created with a very precise oscillating machine called a microkeratome. In bladeless LASIK, the flap is created using a different type of laser. Both options have their benefits, and overall the results and safety profiles are very similar. We offer both technologies in our practice.  Dr. Vishteh can inform you of which technology you may be better suited for.

Is LASIK FDA-approved?

Yes. Dr. Armin Vishteh uses only FDA-approved LASIK technology. You can read the FDA’s Information on LASIK to help you understand more about the procedure.
