LASIK & Refractive Surgery
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.
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.
Z-LASIK is different to 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 time between the two steps of the procedure.
With Z-LASIK there is no need to move or to wait, thus the total procedure time is much shorter: for both eyes it usually takes less than ten minutes.
Instant visual recovery
First improvements are noticeable within minutes of completion of the procedure and 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 millimetre.
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.
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 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 to perform in your doctor's office.
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 as that 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 benefit from an eliminated or significantly reduced dependence on glasses or contact lenses, and vision that remains stable over time. This procedure also prevents the patient from developing cataracts in the future.
