LaHayeSIK™: BEYOND LASIK

At LaHaye Total Eye Care, we never stop pursuing perfect vision. That’s why we spent years developing – and getting FDA clearance – on our next-generation laser vision correction procedure called LAHayeSIK™. This revolutionary approach to LAHayeSIK™ was undertaken by leading refractive surgeon Leon C. LaHaye, MD with a single goal in mind: enhance the overall safety, precision and accuracy of the traditional LASIK process while improving outcomes and eliminating the need for enhancements or retreatments.

When compared at every level to traditional LASIK, LAHayeSIK™ is safer and quicker, has more predictable outcomes, reduces complications and significantly reduces the need to perform secondary re-treatments. It accomplishes this by performing the entire procedure in a more controlled, sterile and safer surgical environment than traditional LASIK, which includes NONE of the 10 specialized tasks (see below) utilized by Dr. LaHaye in his LAHayeSIK™ procedure.

TRADITIONAL LASIK

During the past two decades, traditional LASIK has become the safest, most successful and most popular laser vision correction procedure ever developed. More than 10 million men and women around the world today enjoy crisp, clear, unaided vision thanks to traditional LASIK. As impressive as that sounds, Dr. LaHaye continued his development of the LAHayeSIK™ technology in an effort to help perfect the traditional LASIK process.

Traditional LASIK is a 2-step process: The first step involves the creating of a thin protective flap in the outer layer of your cornea. The actual LAHayeSIK™ procedure is performed under this thin layer of tissue that is gently folded back before the laser treats the underlying layer of the cornea. A major disadvantage of traditional LASIK vs. LAHayeSIK™ is the location and placement of the protective flap while the laser treatment is being performed. Surgeons performing traditional LASIK place the flap on the side portion of the eye where unwanted debris and fluids can contaminate the flap. Once the laser treatment has been performed, surgeons then take the exposed flap and return it to its original position where it aids in the healing process.

LAHayeSIK™ – 10 WAYS IT’S BETTER THAN LASIK

The LAHayeSIK™ surgical method utilizes a single, multifunction instrument designed and developed Dr. LaHaye to facilitate and standardize each Stage II maneuver and address sub-optimal issues. Before lifting the corneal flap (incision exposure) the surgeon places the LAHayeSIK™ handpiece on the patient’s eye where it remains through the completion of the procedure. LAHayeSIK™ accomplishes 10-plus specialized tasks providing the surgeon with exquisite, single-instrument control to shorten procedural time, reduce complications and significantly reduce the need for secondary retreatment in most cases.

The second stage of the LAHayeSIK™ refractive procedure—encompassing the opening of the corneal flap to expose the target tissue, excimer laser ablation and precise closure of the flap—is the most critical aspect of refractive surgery with regards to potential complications. Although complications are rare they can and do occur. The majority of complications – and less than desired outcomes we see today – include infectious keratitis, diffuse lamellar keratitis, epithelial ingrowth, de-centered ablation, corneal haze, under-correction and over-correction. Most can be attributed to contamination by surgical debris, inconsistent hydration and dehydration, extraneous instrumentation, inconsistent laser effectiveness due to masking or blocking of the laser beam by moisture and surgical plume, inaccurate laser treatment because of fast saccades, and other factors. Because of these issues the need for additional surgery and subsequent treatments can range from 4% and higher.

Here are the TOP 10 Benefits of the LAHayeSIK™ procedure vs. Traditional LASIK.

I. Surgical Field Isolation and Fluid-tight Containment

The LAHayeSIK™ handpiece outer cone and lower ring design downsizes and contains the surgical field providing unparalleled isolation of the highly absorbent corneal tissues to protect against possible contamination by irrigating fluids, eyelashes, eyelid margins, glandular secretions, backwash, etc.

II. Secure Control of Eye Position

Surgeon-controlled fixation helps ensure accurate treatment and reduces total dependence on complex, sensitive eye tracker systems; saccadic contamination is avoided and patient anxiety is reduced by eliminating their responsibility to fixate.

III. Tamponade

The base of the handpiece tamponades the small ciliary vessels surrounding the cornea to help better manage problematic bleeding. Abrasive sponging to the flap bed margins and procedural delay is minimized or eliminated.

IV. Corneal Flap Management

A pedestal within the handpiece anatomically supports and protects the delicate flap from excessive hydration and pooling fluid contamination.

V. Target Tissue Hydration Control

Selective use of LAHayeSIK’s™ filtered O2 feature uniformly evaporates only the laser beam blocking moisture from the cornea surface to ensure consistant results. There is no need to touch the cornea with sponges or instruments that may contribute to target stromal roughness, and cause excessive or spatial dehydration resulting in attenuation of laser effectiveness.

VI. Surgical Smoke Evacuation

Seven ports designed into the LAHayeSIK’s™ handpiece instantly remove plume at-the-source, eliminating the smokes vertical travel and beam masking variability thereby avoiding errors and other possible complications.

VII. Sterile Surgical Field Irrigation

Pulsing, sterile, antibiotic-fortified irrigation via 4 ports in the LAHayeSIK’s™ handpiece rinses and re-hydrates the corneal tissues easily and consistently while avoiding pooling and backwash thereby providing the means to ensure the cleanest, most consistent and reproducible procedure possible.

VIII. Aspiration of Surgical Debris

Aspiration channels within the instrument instantly remove surgical debris, glandular secretions and other contaminants from the corneal flap and stromal bed.

IX. Controlled Environment

Aeration, irrigation and aspiration combine to maintain a consistent hydration of the cornea, which is essential to predictable and consistent outcomes.

X. Precise Flap Replacement

The hinged pedestal allows proper, precise flap repositioning in a single motion. Excessive flap manipulations, “refloating” manuvers, and instrumentation are avoided while pooling and backwash problems are eliminated.

XI. Rapid Flap Adherence

LAHayeSIK’s ™ O2 aeration feature accelerates and achieves uniform flap adherence in under 15 seconds; extraneous, potentially abrasive instrumentation and sponging is avoided as well as the usual 2 to 5 minute wait for flap bonding.
