STAR S4 IR® Excimer Laser

Personalize Every Procedure

The STAR S4 IR® Excimer Laser delivers 100% personalized ablation based on the proven wavefront-guided technology of the iDESIGN® System.

Powered by the iDESIGN® System’s wavefront-guided measurements, the
STAR S4 IR® Excimer Laser performs a customized treatment that includes the eye’s higher-order aberrations.

 

Exclusive technology helps ensure accurate placement of the laser according to surgeon specifications.

  • Iris Registration technology provides a noncontact, automated method to correctly align and center treatment while allowing for instant re-registration in the event of intraoperative movement
  • Variable Repetition Rate (VRR) delivers Fourier-reconstructed shapes with optimized ablation time while minimizing thermal impact on the cornea
  • Variable Spot Scanning (VSS) technology incorporates an array of varying laser pulse diameters to ensure an accurate match between target and ablation shapes
  • ActiveTrak 3-D Active Eye Tracking technology follows the eye’s motions in three dimensions to capture more than 99.4% of eye movements
  • ActiveTrak Automatic Centering technology locates and automatically sets the treatment center in relation to the pupil center

VSS Simulation Results1

 

In a theoretical simulation, the STAR S4 IR® Excimer Laser’s Variable Spot Scanning (VSS) showed consistently more precise ablation than the alternative single spot scanning (SSS) ablation.1

The STAR S4 IR® Excimer Laser is primed to deliver exceptional visual quality and patient satisfaction.

In a LASIK clinical trial, myopia patients reported significant improvements in ALL measures of visual functioning and well-being six months postoperatively, including:2,3,*

  • Clarity of vision
  • Satisfaction with correction
  • Near vision
  • Far vision
  • Activity limitations
  • Difficulty driving at night

With its broad treatment inclusion criteria, the STAR S4 IR® Excimer Laser allows refractive surgeons to treat a wide range of patients.

INDICATIONS

The STAR S4 IR® Excimer Laser System and the iDESIGN® Refractive Studio is indicated for wavefront-guided laser assisted in situ keratomileusis (LASIK) to achieve monovision by the targeted retention of myopia (-1.25 to -2.00 D) in the non-dominant eye of presbyopic myopes: 40 years or older who may benefit from increased spectacle independence across a range of distances with useful near vision, with myopic astigmatism, up to -6.00 D spherical equivalent as measured by iDESIGN® Refractive Studio, with cylinder up to -3.00 D, and a minimum pre-operative myopia in their non-dominant eye at least as great as their targeted myopia; with an agreement between manifest refraction (adjusted for optical infinity) and iDESIGN® Refractive Studio refraction as follows: Spherical equivalent: Magnitude of the difference is less than 0.625 D; Cylinder: Magnitude of the difference is less than or equal to 0.50 D; Cylinder Axis: If either the manifest cylinder entered into the iDESIGN® Refractive Studio or the iDESIGN® Refractive Studio cylinder selected for treatment is less than 0.50 D, there is no requirement for axis tolerance. When both cylinders have a magnitude of at least 0.50 D, the axis tolerance is linearly reduced from 15º (0.5 D) to 7.5º (7.0 D or greater) based on the average magnitude of both cylinders. With documented evidence of a change in manifest refraction of no more than 0.50 D (in both cylinder and sphere components) for at least one year prior to the date of pre-operative examination; and with a successful preoperative trial of monovision or history of monovision experience. The STAR S4 IR® Excimer Laser System and iDESIGN® Advanced WaveScan Studio System/iDESIGN® Refractive Studio is indicated for wavefront-guided laser assisted in situ keratomileusis (LASIK) in patients: With hyperopia with and without astigmatism as measured by iDESIGN® Advanced WaveScan Studio System/iDESIGN® Refractive Studio up to +4.00 D spherical equivalent, with up to 2.00 D cylinder; with mixed astigmatism as measured by iDESIGN® Advanced WaveScan Studio System/iDESIGN® Refractive Studio where the magnitude of cylinder (1.0 D to 5.0 D) is greater than the magnitude of sphere, and the cylinder and sphere have opposite signs; with myopia as measured by iDESIGN® Advanced WaveScan Studio System/iDESIGN® Refractive Studio up to -11.00 D spherical equivalent, with up to -5.00 D cylinder; with agreement between manifest refraction (adjusted for optical infinity) and iDESIGN® Advanced WaveScan Studio System/iDESIGN® Refractive Studio refraction as follows: Spherical Equivalent: Magnitude of the difference is less than 0.625 D; Cylinder: Magnitude of the difference is less than or equal to 0.5 D; 18 years of age or older, and with refractive stability (a change of ≤1.0 D in sphere or cylinder for a minimum of 12 months prior to surgery).

 

CONTRAINDICATIONS

Wavefront-guided LASIK surgery is contraindicated in patients with collagen vascular, autoimmune or immunodeficiency diseases; in pregnant or nursing women; in patients with corneal abnormalities including signs of keratoconus, abnormal corneal topography, epithelial basement membrane disease (EBMD) and degenerations of the structure of the cornea; in patients with symptoms of significant dry eyes. If the patients have severely dry eyes, LASIK may increase the dryness. This may or may not go away. Severe eye dryness may delay healing of the flap or interfere with the surface of the eye after surgery. It may result in poor vision after LASIK. In patients whose corneal thickness would cause anticipated treatment would violate the posterior 250 microns (μm) of corneal stroma; in patients with advanced glaucoma; in patients with uncontrolled diabetes; in patients with documented evidence of a change in manifest refraction of more than +0.5 D (in both cylinder and sphere components) for at least one year prior to the date of pre-operative examination. in patients taking medications with ocular side effects. Examples are Isotretinoin (Accutane®) for acne treatment or Amiodarone hydrochloride (Cordarone®) for normalizing heart rhythm.

 

WARNING AND PRECAUTIONS

Wavefront-guided LASIK is not recommended in patients who have systemic diseases likely to affect wound healing, such as autoimmune connective tissue disease, diabetes or an immunocompromised status; have a history of Herpes simplex or Herpes zoster keratitis; have severe allergies or tendency rub their eyes often; have glaucoma, elevated IOP, ocular hypertension or being followed for possible glaucoma (glaucoma suspect); are taking the medication Isotretinoin (Accutane®); are taking antimetabolites for any medical conditions. To reduce the risk of corneal ectasia, the posterior 250 microns (μm) of corneal stroma should not be violated. Please refer to Operator’s Manual for a list of additional Precautions.

 

 

CAUTION

U.S. Federal law restricts this device to sale, distribution, and use by or on the order of a physician or other licensed eye care practitioner who has been trained in the calibration and operation of this device.
