简要总结
The purpose of this study is to obtain additional safety and feasibility data on the UV-Femto procedure. Currently, a similar procedure for refractive surgery is approved for treating myopia by removal of a corneal lenticule. However, the approved procedure utilizes IR light to create corneal incisions and the intrastromal lenticule, while UV-FS laser has the advantage of using UV light with a significantly lower pulse energy as compared with standard IR femtosecond lasers. The UV-FS laser has shown preliminary safety and feasibility in removal of lenticules in a high myopic treatment in a previous study.

入选标准
- •Subject must be able to understand and sign an IRB/IEC approved Informed Consent form.
- •Willing and able to attend all scheduled study visits as required per protocol.
- •Myopia with sphere of -0.50 to -10.0 D cylinder <1.00 D (MRSE within -0.50 to -10.0 D).
- •Other protocol defined inclusion criteria may apply.
排除标准
- •Women of childbearing potential, defined as all women who are physiologically capable of becoming pregnant and who are not postmenopausal for at least 1 year or are less than 6 weeks since sterilization, are excluded from participation if any of the following apply: a. they are currently pregnant, b. have a positive UPT result at Screening, c. intend to become pregnant during the study period, d. are breast-feeding. Subjects who become pregnant during the study will not be discontinued; however, data will be excluded from the effectiveness analyses because pregnancy can alter refraction and visual acuity results.
- •Study eye unable to focus for imaging and/or treatment.
- •Acute or chronic disease or illness that would increase the operative risk or confound the outcomes of the study as clinically assessed by the Investigator (including history of Herpes Simplex).
- •Current use of medications with known ocular side effects and photosensitivity, including but not limited to: steroids, antimetabolites, Isotretinoin (Accutane®), Amiodarone hydrochloride (Cordarone),or Hydroxychloroquine (Plaquenil), Tetracyclincs, Nalidixic Acids, and Fluoroquinolones.
