6. Any grade 3 or greater slit lamp findings (e.g. edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA classification scale, any previous history or signs of a contact lens-related inflammatory event (e.g. past peripheral ulcer or round scar), or any other ocular abnormality that may contraindicate contact lens wear.
7. Any ocular infection.
8. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
9. Monovision, multifocal, toric, or extended wear contact lens correction.
10. Participation in any contact lens or lens care product clinical trial within 14 days prior to study enrollment.

120 participants in 2 patient groups

senofilcon A/ delefilcon A/ senofilcon A

Experimental group

Description:

Subjects were randomized to one two lens wear sequences. Subjects randomized to this sequence first wore the senofilcon A contact lens, then wore the delefilcon A contact lens second and then wore the senofilcon A contact lens third.

Treatment:

Device: delefilcon A

Device: senofilcon A

delefilcon A/senofilcon A/ delfilcon A

Active Comparator group

Description:

Subjects were randomized to one two lens wear sequences. Subjects randomized to this sequence first wore the delefilcon A contact lens then wore the senofilcon A contact lens second and then wore the Control lens delefilcon A contact lens third.

Treatment:
