Indications for Use
SynergEyes™ PS (paflufocon D hem-iberfilcon A) Hybrid Contact Lenses are indicated for use in the correction of eyes with refractive errors resulting from corneal surgery or trauma including hyperopia and myopia, astigmatism, and irregular astigmatism in aphakic and not aphakic, nondiseased eyes. The lenses are indicated for daily wear for the correction of up to +20.00 and -20.00 D in eyes with astigmatism or irregular astigmatism up to 6.00 D. The lenses may be disinfected using only a chemical disinfecting system compatible with both hydrogel and rigid gas permeable lenses.
Device Story
Hybrid contact lens featuring rigid gas permeable (RGP) center (paflufocon D) and soft hydrophilic skirt (hem-iberfilcon A). Lathe-cut design; 14.5mm diameter. Acts as refracting medium to focus light on retina. Used by patients with post-surgical or trauma-related refractive errors. Prescribed by eye care professionals. Lens provides vision correction for irregular corneal surfaces. Benefits include improved visual acuity for patients with complex refractive needs. Disinfection requires chemical systems compatible with both RGP and hydrogel materials.
Clinical Evidence
Three-month prospective clinical study (n=76 dispensed) evaluated safety and effectiveness for post-surgical/trauma refractive correction. Primary endpoints: visual acuity, wearing time, adverse events. Results: 81.3% of completed subjects achieved 20/40 or better VA. Average daily wearing time 10.6 hours. Adverse events included photophobia, corneal abrasion, and keratitis. Discontinuation rate 42.1%, primarily due to comfort and poor outcomes, consistent with the complex patient population.

## 6. Non clinical studies:
Results from the full series of physical/chemical, toxicological, and sterility tests were conducted under K051035 for the equivalent lens, the predicate lens for this device. No further non-clinical studies were performed for this submission.
## 7. Packaging
The primary lens container for shipping is a sterile enclosed medical grade glass vial capped with a screw cap and sterilized with the e-beam sterilization process. The lens is immersed in a sterile buffered normal saline.
## 8. Clinical data:
A three month clinical study of the SynergEyes™ PS Hybrid Contact Lens was conducted to assess safety and effectiveness for vision correction in daily wear for patients suffering from post surqical refractive error including nearsightedness, astigmatism and irregular astigmatism, or trauma to the eye. The study was designed to evaluate contact lens visual acuity and wearing time; and assess contact lens adverse events and loss of visual acuity.
## Overall Findings:
A total of 76 subjects were dispensed into the study of which 44 (80 eyes) [57.9%] completed the study and 32 subjects (58 eves) [42.1%] were discontinued from the study. An additional 8 subjects were not dispensed lenses.
{3}------------------------------------------------
SynergEyes™, Inc. Carlsbad, CA 92008
The population demographics were similar to other contact lens studies with a female to male gender ration of 1.3 to 1.0. The average age of the completed and discontinued subjects was 49 and 43.5 respectfully.
## Safety:
Eight (8) adverse events were reported during the study for 4 completed subjects and 3 discontinued subjects. The adverse events included 1 painful light sensitivity (photophobia); 1 loose interrupted suture and infiltrate; 1 abrasion of the cornea upon lens removal; 1 small superficial abrasion; 1 subject (2 eyes) with swelling of the corneas due to inadequate rinsing of hydrogen peroxide disinfection solution from lenses; 1 allergic conjunctivitis; and 1 keratitis intis.
Thirty-two (32) subjects (58 eyes) [42.1%] were discontinued from the study. An additional 8 subjects were never dispensed lenses. The most common reasons for discontinuation were poor outcome with lenses (32.5%), poor comfort (27.5%), poor vision (12.5%), loss of interest (10.0%), non-compliance (10.0%), and handling difficulty (2.5%).
Symptoms, Problems, and Complaints: For the completed eyes, no symptoms were reported at 46.2% of the dispensing visit or follow-up visit examinations and for discontinued eves no symptoms were reported at 28.8% of the dispensing visit or follow-up visit examinations. Symotoms decreased over time for completed eyes but not for discontinued eyes. The most common symptoms reported were discomfort and awareness (28.4% completed, 45.8% discontinued), dryness and scratchiness (23.4%, 22.1%), itchiness and burning (9.3%, 8.9%), and variable vision (8.2%, 13.3%).
#### Efficacy:
Visual Acuity- Final visual acuity for completed subjects was 20/20 or better (20.0%), 20/25 or better (45.0%), 20/30 (68.8%), and 20/40 or better (81.3%). The visual acuity rates for discontinued subjects were 8.6%, 39.7%, 53.4%, and 70.7% respectfully. Vision correction fluctuated as expected with the instability of the corneal curvature from post surgical conditions and trauma under the contact lens contributing to the change. Three (3) completed eyes and 8 discontinued eyes were reported to have VA decreases of more than 2 lines of Snellen VA when comparing the contact lens VA with the best corrected VA. These findings are expected with this population.
For Wearing Time: Over the study period the average daily wearing time reported by completed patients was 10.6 hours per day.
#### Conclusion:
The SynergEyes™ PS Hybrid Contact Lens for Post Surgical refractive error and cases involving trauma provided satisfactory performance as expected. The higher than estimated discontinuation rate was anticipated due to the nature of the subject population with the inclusion of subjects who might otherwise have less successful outcomes with other lens types. Overall, the lens performance demonstrated safe and effective use of the device for its intended use.
#### 9. Conclusions drawn from studies Substantial Equivalence:
Information provided in this 510(k) establishes that the SynergEyes™ PS Hybrid Contact Lens are equivalent in optical, chemical and physical properties of the predicate devices and do not raise any questions of safety and effectiveness. The clinical evaluation demonstrated safe and effective lens performance, and where possible equivalence to historical experience with predicate devices. The device is substantially equivalent to the predicate devices material, SynergEves A and M Hybrid Contact Lens (K051035), Paragon HDS-100 (P870024/S36 and
