Safety and Effectiveness of the TENEO 317 Model 2 (1.28 US) Excimer Laser for Laser In Situ Keratomileusis (LASIK) Surgery to Treat Hyperopia With or Without Astigmatism

January 22, 2026 updated by: Bausch & Lomb Incorporated

A Study to Investigate the Safety and Effectiveness of the TENEO 317 Model 2 (1.28 US) Excimer Laser for Laser In Situ Keratomileusis (LASIK) Surgery to Treat Hyperopia With or Without Astigmatism

This will be a multicenter, prospective, open label, non-randomized, single arm 12 month study, evaluating the safety and effectiveness of the TECHNOLAS TENEO 317 Model 2 (Software version "1.28 US") excimer laser when used in LASIK surgery to treat hyperopia with or without hyperopic astigmatism. Both eyes of a subject may be enrolled so long as both eyes meet all inclusion/exclusion requirements. Analysis of the primary effectiveness endpoint will be completed at refractive stability.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

22 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Subjects 22 years of age or older at the time of the pre-operative examination.
  2. Manifest, distance corrected visual acuity (CDVA) 20/25 (logMAR 0.10) or better in an operative eye
  3. Pre-operative refractive error of hyperopia with spherical component of 0.00 D to +4.00 D with or without cylinder up to +2.00 D, with MRSE of ≥ 0.375 D and ≤ +5.00 D based on the manifest refraction in thestudy eye(s). This would exclude eyes with cylinder-only corrections < +0.75D and sphere-only corrections < +0.375D)
  4. Difficulty maintaining uncorrected distance visual acuity (UDVA) of 20/40 or better, as evidenced by need for constant contact lens or spectacle wear.
  5. Difference between manifest refractive and cycloplegic spherical equivalent ≤ 0.75 D, difference between manifest and cycloplegic cylinder ≤ ± 0.50 D and difference between manifest and cycloplegic cylinder axis ≤ ± 15 degrees.
  6. Stable refraction (i.e., a change of ≤ ± 0.50 D in MRSE) for a minimum of 12 months prior to surgery, as verified by consecutive refractions, medical records, or prescription history.
  7. Agree to discontinue use of contact lenses for at least 2 weeks (for rigid or toric lenses) or 3 days (for soft contact lenses) prior to the first refraction used to establish stability and through the day of surgery.
  8. All contact lens wearers must demonstrate a stable refraction in an eye to be treated, as follows: two consecutive examinations at least 1 week apart within ± 0.50 D manifest refractive spherical equivalent and within ± 15 degrees cylinder axis.
  9. Agree to emmetropia correction for each treated eye.
  10. Anticipated postoperative stromal bed thickness of at least 250 microns.
  11. Can lie flat without difficulty.
  12. Willing and able to read, understand, and sign a written informed consent form (ICF).
  13. Willing and able to comply with the schedule for all post-surgery follow-up visits.

Exclusion Criteria:

  1. Acute or chronic disease or illness that would increase operative risk or confound the results of the study (e.g., dry eye disease, cataract, glaucoma, immuno-compromised, rheumatoid arthritis, clinically significant atopic disease, acne rosacea, autoimmune disease, endocrine disorders, lupus, systemic connective tissue disease, diabetes, or severe atopic disease).
  2. Use of 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., systemic corticosteroids, antimetabolites).

  3. Ocular conditions, other than hyperopia with or without astigmatism that may predispose the subject to future complications including but not limited to:

    3. Evidence or history of glaucoma or glaucoma suspect (IOP > 24mmHg) by exam findings and/or family history
  4. 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.
  5. An increased risk for developing strabismus post-treatment or an ocular muscle disorder (e.g., strabismus or nystagmus) affecting fixation.
  6. Known sensitivity to any study medications (e.g., used during LASIK procedure and postoperative care).

  8. Have mixed astigmatism.
  9. Presence of keratoconus, keratoconus suspect, subclinical or forme fruste keratoconus, corneal dystrophy, or other corneal irregularity (e.g., irregular astigmatism) or abnormal corneal topography
