研究概览
简要总结
This is a single-arm, non-comparative, uncontrolled, open-label, monocular study to assess the safety and device performance of a hypersonic vitrector handpiece.
Eligible subjects who are enrolled in the study will undergo a screening visit up to 14 days prior to surgery, a vitrectomy procedure in the study eye, and be clinically followed for 3 months after surgery.
Enrolled subjects who meet eligibility criteria will be seen according to the following schedule:
Pre-operative Visit Day -14 to -1
Operative Visit Day 0
Post-operative Visit 1 1 Day
Post-operative Visit 2 7 Days +/- 2 days
Post-operative Visit 3 30 Days +/- 7 days (interim observations)
Post-operative Visit 4 90 Days +/- 14 days (final observations)

入选标准
- •This study will include subjects who meet all of the following: 1.Subjects must be 40 years of age or older on the date the Informed Consent Form (ICF) is signed.
- •2.Subjects must provide written informed consent on the IRB/EC-approved Informed Consent Form (ICF) and provide authorization as appropriate for local privacy protection regulations.
- •3.Subjects must be willing and able to comply with all treatment and follow-up study procedures.
- •4.Subjects undergoing optical coherence tomography (OCT) and fundus imaging must have adequate pupillary dilatation and clear media to perform imaging studies including fundus fluorescein angiography.
- •5.Subject must have a clinical indication for vitrectomy based on a diagnosis of one of the following conditions: vitreoretinal traction, asteroid hyalosis, macular pucker/epiretinal membrane, macular hole, or vitreous hemorrhage 6.Subject must have uncorrected visual acuity worse than 20/40 (Snellen) at Visit 1.
排除标准
- •The patients will be excluded from the study based on the following exclusion criteria: 1.Subjects who have participated in any drug or device clinical investigation within 30 days prior to entry into this study and/or will participate in another investigation during the period of study participation.
- •2.Subjects with retinal disorders in the study eye that may confound interpretation of or prevent obtaining fundus fluorescein angiography (FA) or OCT images, including retinal vascular occlusion, choroidal neovascularization, macular atrophy or scarring, ocular histoplasmosis, or pathologic myopia.
- •3.Subjects who have had prior vitrectomy surgery, cryopexy, or retinal buckle procedure.
- •4.Subjects with prior history of retinal tear, vitreoretinal tractional detachment, or ocular tumors in either eye.
- •5.Subjects with visual acuity of No Light Perception at Visit
- •6.Female subjects of child-bearing potential who have a positive urine test for pregnancy at Visit
- •7.Subjects who have experienced any significant trauma in the operative eye within the past month.
- •8.Subjects with any active ocular infection or history of any herpetic infection that has cleared less than one month prior to the pre-operative visit.
- •9.Subjects with history of complicated cataract surgery involving vitreous loss or a history of vitreoretinal surgery in the study eye.
- •10.Subjects with uncontrolled glaucoma or ocular hypertension (IOP > 24 mmHg) in the operative eye.
- •11.Subjects with dislocated lens or retained lens fragments.
- •12.Subjects with a known bleeding disorder or using drugs known to increase the likelihood of bleeding.
- •13.Subjects with uveitis refractory to treatment.
- •14.Subjects with significant anterior segment abnormality that would interfere with visualization of the vitreous or retina.
- •15.Subjects with a known allergy to sodium fluorescein dye.
- •16.Subjects with any medical condition (e.g., uncontrolled diabetes) that, based on the Investigator’s medical judgment, poses a concern for the subjects’ safety.
