Study Summary

The Use of the VisuMaxTM Femtosecond Laser Small-Incision Lenticule Extraction (SMILE) Procedure for the Correction of Myopia with or without Astigmatism study is a prospective, non-randomized, multicenter clinical study that will be conducted by the Navy Refractive Surgery Center, Naval Medical Center San Diego, CA in collaboration with the U.S. Air Force 59th Medical Wing, Wilford Hall Eye Center, TX, and the U.S. Army Warfighter Refractive Eye Surgery Program and Research Center, Fort Belvoir Community Hospital, VA.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  1. Male and female subjects age 22 years of age and older either active duty ordependents who are eligible for care;
  2. Myopia from ≥ 0 D to ≤ -10.00 D with ≤ -3.00 D cylinder and MRSE ≥ -1.00 D to ≤ -11.50 D in the eye(s) to be treated;
  3. A stable refraction for the past year, as demonstrated by a change in MRSE of ≤ 0.50 Din the eyes to be treated;
  4. A difference between cycloplegic and manifest refractions of ≤ 0.75 D spherical equivalent in both eye(s);
  5. UCVA 2 lines worse than BCVA in the treated eye(s);
  6. BSCVA at least 20/20 in the treated eye(s);
  7. Discontinue use of contact lenses for at least 4 weeks (for hard lenses) or 2 weeks (for soft lenses) prior to the preoperative examination, and through entire study. Thesubject shall not be considered a contact lens wearer if they are not wearing hardcontact lenses for 4 weeks or soft contact lenses for 2 weeks.
  8. All contact lens wearers must demonstrate a stable refraction (within ±0.5 D), asdetermined by MRSE, on two consecutive examinations at least 7 days apart, in theeye(s) to be treated;
  9. Central corneal thickness of at least 500 microns in the both eye(s);
  10. Willing and able to return for scheduled follow-up examinations;
  11. Able to provide written informed consent and follow study instructions in English.
  12. Permission of the Commanding Officer for active duty subjects to receive refractivesurgery and participate in the study.

Exclusion

Exclusion Criteria:

  1. Manifest cylinder of more than -3.00 D;
  2. Estimated treatment depth is less than 250 microns from the corneal endothelium;
  3. Eye to be treated is targeted for monovision;
  4. Keratometry readings via Sim-K values less than 40.00 D;
  5. Abnormal corneal topographic findings, e.g. keratoconus, pellucid marginaldegeneration in either eye;
  6. History of or current anterior segment pathology, including cataracts in the eye to betreated;
  7. Clinically significant dry eye syndrome unresolved by treatment in either eye;
  8. Residual, recurrent, active ocular or uncontrolled eyelid disease, corneal scars orother corneal abnormality such as recurrent corneal erosion or severe basementmembrane disease in the either eye;
  9. Ophthalmoscopic signs of progressive or unstable myopia or keratoconus (or keratoconussuspect) in either eye;
  10. Irregular or unstable (distorted/not clear) corneal mires on central keratometryimages in either eye;
  11. History of ocular herpes zoster or herpes simplex keratitis;
  12. Deep orbits, strong blink, anxiety, pterygium, or any other finding suggestingdifficulty in achieving or maintaining suction;
  13. Difficulty following directions or unable to fixate;
  14. Previous intraocular or corneal surgery of any kind in the eye to be treated,including any type of surgery for either refractive or therapeutic purposes;
  15. History of steroid-responsive rise in intraocular pressure, glaucoma, or preoperativeIOP > 21 mmHg in either eye;
  16. History of diabetes, diagnosed autoimmune disease, connective tissue disease orclinically significant atopic syndrome;
  17. Immunocompromised or requires chronic systemic corticosteroids or otherimmunosuppressive therapy that may affect wound healing;
  18. History of known sensitivity to planned study medications;
  19. Participating in any other ophthalmic drug or device clinical trial during the time ofthis clinical investigation;
  20. Pregnant or lactating;
  21. Anyone who has the potential to deploy or relocate during the follow-up period.
  22. Systemic Medications that may confound the outcome of the study or increase risk tothe subject, including but not limited to steroids, antimetabolites, etc.
  23. Evidence of retinal vascular disease.
  24. Glaucoma suspects by exam findings or family history.

Study Description

Prospective, multicenter, open-label, non-randomized clinical trial with bilateral commercial treatment for FDA approved indications and unilateral treatments for investigational refractive errors. Data from each treated eye of subjects will be treated independently. Monovision treatments and retreatments of the study eye will not be allowed during the course of the study. Successful bilateral treatment is required for performance based testing and patient reported outcome testing. Subjects will be randomized into the 0.25 and 0.50 sphere only and spherical cylinder bins using a sequential alternating randomization with an equal number assigned to both bins. Other subjects will be assigned to the bins they qualify for as they are enrolled into the study. Appointments are given to patients requesting refractive surgery randomly.

Three military sites in the U.S.A.: Navy Refractive Surgery Center, Naval Medical Center San Diego, CA in collaboration with the U.S. Air Force 59th Medical Wing, Wilford Hall Eye Center, TX, and the U.S. Army Warfighter Refractive Eye Surgery Program and Research Center, Fort Belvoir Community Hospital, VA.
