Brief Summary

This will be a multicenter, prospective, open label, non-randomized, single arm study evaluating the safety and effectiveness of the Technolas® TENEO 317 Model 2 (version 1.28 US software) Excimer Laser when used in LASIK surgery to treat myopia or myopic astigmatism. One or both eyes of a subject may be treated so long as both eyes meet all inclusion/exclusion requirements.

Conditions

Myopic Astigmatism

Outcome Measures

Primary Outcomes (3)

• The percentage of eyes that achieve predictability (attempted versus achieved) of MRSE within ± 0.50 D

  Assessed for approximately 12 months

• The percentage of eyes that achieve predictability (attempted versus achieved) of MRSE within ± 1.00 D

  Assessed for approximately 12 months

• The percentage of eyes that achieve a UDVA of 20/40 or better

  Assessed for approximately 12 months

Surgery to Treat Myopia or Myopic Astigmatism with Sphere between 0.00D and -1.00D

TENEO 317 Model 2 (1.28 US) Excimer Laser

Eligibility Criteria

• Age: 22 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Are 22 years of age or older.
• Have read, understood, and signed an ICF.
• Have demonstrated stable refraction (i.e., a change of ≤ ± 0.5 D in sphere and cylinder) for a minimum of 12 months prior to surgery verified by consecutive refractions, medical records or prescription history.
• Have myopic refractive error with or without astigmatism; sphere 0.00 D up to -1.00 D, cylinder between 0.00 D and -3.00 D; with a manifest refraction spherical equivalent (MRSE) between -.0375 D and -2.50 D.
• Wears distance correction or has a need for distance correction.
• Have manifest, distance best spectacle corrected visual acuity (BSCVA) of 20/25 (logMAR 0.1) or better in an operative eye.
• Have equal to or less than 0.50 D spherical equivalent (SE) difference between cycloplegic and manifest refractions at Visit 1 (Pre-operative).
• Have normal corneal topography as determined by the Investigator.
• Anticipated postoperative stromal thickness of at least 350 microns.
• Have discontinued use of contact lenses for at least 2 weeks (for hard or toric lenses) or 3 days (for soft contact lenses) prior to the pre-operative examination, and through the day of surgery.
• All contact lens wearers must demonstrate a stable refraction (within ± 0.5 D), as determined by MRSE, on two consecutive examinations at least 1 week apart, in an eye to be treated and the axis of cylinder should not differ by more than 15 degrees from the baseline cycloplegic refraction.
• Agree to emmetropia correction for each treated eye
• Have the ability to lie flat without difficulty.
• Are willing and able to comply with the schedule for all post-surgery follow-up visits.

You may not qualify if:

• Subjects for whom the combination of their baseline corneal thickness and the planned operative parameters for the LASIK procedure would result in treatment depth less than 250 microns from corneal endothelium.
• Acute or chronic disease or illness that would increase operative risk or confound the results of the study (e.g., dry eye, cataract, immuno-compromise, rheumatoid arthritis, clinically significant atopic disease, acne rosacea, autoimmune disease, endocrine disorders, lupus, systemic connective tissue disease, diabetes, or severe atopic disease).
• Ocular conditions that may predispose the subject to future complications, including but not limited to:
• History or evidence of retinal vascular disease
• History or evidence of active corneal disease or infection (e.g., recurrent corneal erosion syndrome, herpes simplex or herpes zoster keratitis) in either eye.
• History of or evidence of glaucoma or glaucoma suspect (e.g., IOP \> 21 mmHg).
• Eyes for which the baseline manifest subjective refraction exhibits a difference greater than 0.50 D in sphere power, or a difference greater than 0.50 D in cylinder power, or a difference in cylinder axis of more than 15 degrees compared to the baseline cycloplegic subjective refraction. For manifest cylinder of less than 0.50 D, the difference in cylinder axis will not be taken into consideration.
• Subjects for whom the pre-operative assessment of the cornea indicates that one or both eyes are not suitable candidates for treatment based upon the Investigator's medical judgment.
• Have evidence of retinal vascular disease.
• Have a history of or have active corneal disease or infection (e.g., recurrent corneal erosion syndrome, herpes simplex or herpes zoster keratitis, etc.) in either eye.
• Have a known sensitivity to any study medication.
• Have central corneal scars affecting visual acuity or unstable keratometry with irregular mires in an eye considered for eligibility.
• Presence of keratoconus, subclinical or forme fruste keratoconus, corneal dystrophy, unstable central keratometry readings with irregular mires, or other corneal irregularity (e.g., irregular astigmatism).
• Had previous intraocular or corneal surgery in an eye considered for eligibility that might confound the outcome of the study or increase the risk to the subject.
• Use chronic medications by any administration route that may increase risk to the subject or may confound the outcome of the study, including those known to affect wound healing (e.g., corticosteroids, antimetabolites, etc.).
