LASIK is a safe, reliable, and painless way to improve vision without the need for glasses or contact lenses. The procedure is effective for many patients with nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
LASIK is very popular, with about 700,000 procedures performed every year. Current research shows that 99 percent of patients achieve vision that is better than 20/40.
Since LASIK was approved by the U.S. Food and Drug Administration in 1998, it’s undergone many advancements. Today, it is well regarded as an easy and effective way to achieve clear vision. Click here for our FAQ's about LASIK Surgery »
Why Should You Get Lasik
LASIK can correct common vision problems, such as nearsightedness, farsightedness, and astigmatism. This means you often won’t have to rely on glasses or contact lenses. In fact, over 90 percent of people who undergo LASIK achieve 20/20 vision.
Advances in technology mean that surgeons are able to more easily map the cornea during LASIK, resulting in better vision outcomes and fewer side effects. Various studies have concluded that LASIK is a safe long-term solution to improve vision.
As a quick procedure, you’ll enjoy results from LASIK within a few hours of the surgery, with vision stabilizing over a few weeks. You can usually resume normal activities within 48 hours.
Ultimately, you can gain greatly improved vision. Most people find they no longer need to wear glasses or contacts after LASIK, giving them an immense sense of freedom.
Who Is Eligible for Lasik
If you have farsightedness, nearsightedness, or astigmatism, you’re potentially a good candidate for LASIK. To be eligible for the surgery, you must meet these requirements:
- You must be at least 18 years old, signifying that your vision is not rapidly changing.
- You have a stable eye prescription. If your prescription has fluctuated in the past year, it’s best to hold off on LASIK for the time being.
- You must have good overall eye health with no active eye diseases.
- Your corneas must be thick enough for the surgery. Your surgeon will assess this in your consultation.
- Your refractive error must be correctable with glasses or contacts. In some cases, LASIK is unable to correct very severe refractive errors.
In your pre-surgical consultation, your surgeon will evaluate your overall eye health and refractive error to determine if you’re a good candidate for LASIK.
Effectiveness of Lasik Surgery
LASIK boasts very high success rates. In fact, LASIK is known to have one of the highest patient satisfaction rates of any elective procedure.
As LASIK is continuously studied, experts have repeatedly concluded that it is a major success story, with patients enjoying dramatically improved vision with few side effects.
In your pre-surgery consultation, your surgeon will give you a clear idea of what you can personally expect from LASIK. You can expect to significantly reduce your reliance on corrective lenses or even do away with them altogether, depending on the severity of your refractive error.
What is Z-LASIK?
Z-LASIK is a LASIK procedure performed with the Ziemer FEMTO LDV femtosecond surgical laser in conjunction with any one of the leading excimer lasers. Dr. John Davidson was the first surgeon in Ventura County to use the Ziemer Crystal Line laser.
A Fast procedure
Z-LASIK is different from all other treatments because the Ziemer FEMTO LDV femtosecond laser is used as an integrated part of the excimer laser.
Other systems require movement of the patient between two different lasers and, often, a waiting period between the two steps of the procedure.
With Z-LASIK, there is no need to move or wait. Thus, the total procedure time is much shorter. For both eyes, it usually takes less than 10 minutes.
Instant visual Procedure
Initial vision improvements are noticeable within minutes of the procedure’s completion. Optimal visual results are usually reached within less than four hours.
The high-precision FEMTO LDV laser provides for better results. This occurs precisely within one-hundredth of a millimeter.
Due to this high precision, the Z-LASIK procedure enables the surgeon to tailor the procedure according to the very unique characteristics of each patient.
Excessive, insufficient or uneven corneal curvature may be surgically corrected using LASIK, LASEK or other refractive procedures to improve vision and reduce or eliminate the need for eyeglasses or contact lenses. Click here for our FAQ's about Refractive Surgery »
Photorefractive Keratectomy (PRK)
Photorefractive keratectomy (PRK) is a unique laser vision correction procedure that uses an excimer laser to burn away a small amount (about 5 to 30 percent) of the top of the cornea in order to correct refractive errors.
Instead of cutting a flap into the cornea with a blade like the LASIK procedure, this method preserves the strength of the cornea and avoids the risk of perforation and other flap errors that are commonly associated with the blade method.
During the PRK procedure, the eyes are numbed with anesthetic eye drops before your doctor uses targeted laser energy to correct the shape of the cornea. The doctor has complete control over the laser throughout the procedure for highly precise, customized results, designed to give each patient the best vision for their individual eyes. The entire procedure takes only a few minutes in your doctor's office.
Alternative to LASIK - Refractive Lens Exchange
Refractive lens exchange, also called clear lens extraction, replaces the natural lens with a multifocal intraocular lens (IOL) in patients wishing to correct high farsightedness, high nearsightedness, or presbyopia without undergoing a corneal modification procedure such as LASIK. Patients can choose from a wide range of IOLs in order to achieve the best possible vision for their individual eyes.
The refractive lens exchange procedure is the same that is used in cataract surgery. The only difference is that refractive lens exchange is performed to achieve refractive correction rather than cataract removal. Refractive lens exchange involves a rapid recovery and offers patients dramatic improvement in vision quality.
After surgery, patients enjoy clearer vision and greater focusing power almost immediately. Most patients benefit from an eliminated or significantly reduced dependence on glasses or contact lenses, and vision that remains stable over time. This procedure also prevents patients from developing cataracts in the future.
No matter what type of LASIK you choose, you’ll enjoy improved vision after the procedure. Talk to your doctor about what type of LASIK is best for you and what to expect from the surgery.
