Phase III Presbyopia Correction Using the VIS Opti-K™ System (Opti-K™)

August 30, 2024 updated by: VIS, Inc.

Phase III Presbyopia Correction Using the VIS Optimal Keratoplasty (Opti-K™) System (Phase IIIa)

The goal of this clinical trial is to evaluate the safety and efficacy of using the VIS Opti-K System to enable monovision by providing temporary improvement in near vision through the treatment of the non-dominant eye of low myopic, emmetropic and low hyperopic presbyope subjects. The main questions it aims to answer are determining uncorrected near visual acuity at 40cm in the treated eye and subjective improvement as measured by the patient satisfaction questionnaire.

Description

Inclusion Criteria:

  1. Subject age is equal to or greater than 40 years old.
  2. Subjects must have a manifest refraction spherical equivalent (MRSE) between -0.5 D and +0.25 D with no more than 0.75 D of refractive cylinder needing +1.00 D to +2.50 D of reading add in both eyes.
  3. Documented stable refractions defined as 0.5 D or less change in MRSE per year for 12 months or longer prior to primary Opti-K™ treatment, based on refractions, medical records, or prescription history.
  4. Uncorrected distance visual acuity (UDVA) 20/25 or better (i.e., LogMAR ≤ 0.10) in both eyes.
  5. Best corrected distance visual acuity (CDVA) of 20/20 or better (i.e., LogMAR ≤ 0.00) in both eyes.
  6. Uncorrected near visual acuity (UNVA) between 20/50 (LogMAR 0.40) and better than 20/100 (LogMAR < 0.70) in the non-dominant eye.
  7. Best corrected near visual acuity (CNVA) of at least 20/20 in both eyes (LogMAR ≤ 0.00).
  8. Subject has normal corneal topography.
  9. Subject must have documented monovision tolerance (per Appendix B)
  10. Subject is not a contact lens wearer or, if wearing contact lenses, has discontinued wearing contact lenses for the required period of time and completed the contact lens stability check as described below.

    a. Contact Lens Wearers Only: Demonstration of a stable refraction, defined as two manifest refractions that are within ± 0.5 D MRSE of each other as determined under the following conditions: i. The two refractions are performed at least 7 days apart; and, ii. Contact lenses are not worn for at least the specified period prior to the first refraction used to establish stability and through the day of surgery:

    Contact Lens Type Minimum Discontinuation Time Soft 3 Days Soft Extended Wear 1 Week Soft Toric 2 Weeks Rigid gas permeable 2 Weeks

  11. Subject is willing and able to comply with all pre-treatment and follow-up requirements, including the ability to read English to complete the PROWL questionnaire
  12. Subject understands the nature of the procedure, as well as potential risks or limitations of the treatment, and provides informed consent.
  13. Subject will make every effort to have no other refractive or ocular surgery during their study post-treatment follow-up period.

Exclusion Criteria:

  1. Latent hyperopia 1.0 D (i.e., baseline MRSE and CRSE should not differ by or be more than 1.0 D or CRSE).
  2. Nystagmus.
  3. Significant conjunctivochalasis defined as laxity and/or looseness of the conjunctiva when traction is applied and/or redundancy in its normal state. If there is no redundancy of the conjunctiva under normal conditions, there should be no more than 3 mm of conjunctival movement on the bulbar surface in the cardinal fields of gaze and/or by displacement for the patient to qualify for enrollment.
  4. Any active ocular surface disease of any severity.
  5. Any condition causing a cloudy cornea (e.g., scarring, dystrophies, epithelial or stromal edema) or cloudy anterior chamber.
  6. Allergy to anesthetics or post-treatment medications, including NSAIDS.
  7. History or current evidence of chronic allergic reactions, tearing and/or ocular irritation that might confound the outcome or increase the risk of the study.
  8. The use of systemic medications that may confound the outcome or increase the risk of the study, including, but not limited to corticosteroids, antimetabolites, amiodarone, chloroquine, isotretinoin, sumatriptan, or other medications that may affect healing.
  9. Subjects with a recent history (within one week prior to treatment) of using topical ophthalmic medications containing preservatives (such as benzalkonium chloride, except for medications specifically required in this protocol) and/or other ocular drugs that are cytotoxic.
  10. Those with ocular manifestations of acute or chronic illness that might increase the risk or confound the outcome of the study (e.g., diagnosed autoimmune disease, systemic connective tissue disease, clinically significant atopic disease, unstable diabetes mellitus and all diabetes with ocular involvement, etc.).
  11. Pregnant, planning to become pregnant, or lactating women.
  12. Subjects participating in other ophthalmic clinical trials during this clinical investigation.
  13. Persons who, in the determination of the investigator, are not competent to understand the procedure or the actions asked of them as research subjects or have unrealistic expectations or are considered emotionally labile.
  14. Persons who may not be able to complete the requirements of returning to the investigator's clinic over the period of the study, or who may be difficult to locate or contact on short notice. This does not preclude vacations or travel.
  15. Subjects who are likely to be exposed to high levels of ultraviolet radiation (from sunlight, tanning lights, etc.) without protective eyewear during the one- year period following Opti-K™ treatment.
  16. Presence or history of any other condition or finding that, in the opinion of the investigator, makes the subject unsuitable as a candidate for Opti-K™ treatment or study participation or may confound the outcome of the study.
  17. Presence of a pupil irregularity (e.g., decentered pupil or irregular shape) in the eye to be treated that could predispose the eye to a centration error during the treatment.
  18. Previous intraocular or corneal surgery of any kind in either eye, including any type of surgery for either refractive or therapeutic purposes.
  19. Subjects using topical ophthalmic medications to treat presbyopia or plan to use these medications during the study follow-up period.
