During all-laser LASIK surgery, or IntraLASIK, a femtosecond laser, rather than a blade, is used in the first part of the procedure. At SightMD, we are proud to feature the IntraLase iFS™ Laser for superior precision during the first part of iLASIK.
The Most Advanced Femtosecond Laser
Our IntraLase™ iFS™ 5th Generation laser is used during the first step in the iLASIK procedure, during which a flap is created on the outer surface of the cornea. The IntraLase™ iFS™ is the most advanced iLASIK flap laser available today, for several reasons.
The iFS™ laser is three times faster than the fourth-generation IntraLase™. It creates the corneal flap in fewer than 10 seconds, using less energy per pulse than prior laser generations. This reduces the chances of flap edema and inflammation and increases visual recovery post-operatively. Additionally, patients are in surgery for less time and can begin recovery immediately.
This laser is able to create inverted, 150-degree angled cuts from the side of the corneal flap. Because of the sharper angle of the cut, the flap adheres better post-surgery and is three times more stable than the microkeratome blade, the standard of the past in LASIK. With this zig-zag-shaped flap, the edge fits more securely when replaced, locked in for superior healing stability. Patients are also less likely to experience post-surgery dry eye, less likelihood of inflammation because of the snug fit, and improved severed nerve apposition.
The IntraLase™ iFS™ can also create elliptical flaps for elliptical corneas, so the exposed stromal bed and flap are more symmetric to the eye. Additionally, because of the elliptical shape, the flap fold, or hinge, where the corneal flap is still connected and folds over itself, lies at the edge of the stromal bed. This is an improvement from the older generation IntraLase™ iFS™, which made a circular shape. This shape in some cases would cover a portion of stromal bed where the flap folded over itself. The hinge is also larger, which reduces the chance that the hinge will become damaged or disconnected.
Proven Superior Technology
The IntraLase™ iFS™ Technology has proven advantageous over traditional use of a microkeratome steel blade in flap creation during LASIK for many patients. Femtosecond laser technology for flap creation takes less time, has less healing time, has the capability to treat more varied vision conditions, and is safer. iLASIK technology now has the capability to treat nearsightedness, farsightedness, and astigmatism.
This system’s precision is preferable for many patients because of its superiority in vision improvement, consistency, and safety:
- The flap is entirely uniform across the surface of the eye, as the laser automatically deposits laser light (to create the bubbles) at a consistent depth across each eye. This depth is predetermined by our ophthalmologists according to each patient’s unique conditions and needs.
- The IntraLase™ iFS™ Laser System performs better than traditional steel microkeratome blades in three safety areas: flap thickness, induced astigmatism, and cell injury. Flaps made with the laser are more uniform, regular, and precise in shape and length than microkeratome blades. This is safer for the eye and allows for better visual recovery.
- In IntraLASIK™, there are minimal occurrences of decentered, buttonhole, incomplete, or free corneal flaps.
- There is no risk of corneal abrasion.
- The iFS™ incision is smooth across the stromal bed, creating clearer vision post-surgery and more uniform healing.
- Versus PRK-treated eyes, IntraLase iFS™-treated patients have shown improved vision in many studies.
- Patients have shown fewer visual ailments post-surgery, including haze, glare, sensitivity, pain, and dryness.
- The dimensions and data for each iLASIK surgery are saved within the IntraLase™ iFS™ Laser System, so they can be referenced for the patient when necessary, and referenced for patients with similar eye conditions.
In addition to flap creation, the IntraLase iFS™ system is also suited to create corneal incisions during corneal transplant surgery.
