Summary

"This trial aims to compare the performance of two types of contact lenses, LID233309 and Oasys multifocal, when worn daily to see which one works better for people needing multifocal vision

Who is the study for?
This trial is for individuals with presbyopia, which is a common condition where the eyes lose the ability to see close objects clearly. Participants should need multifocal contact lenses and be willing to use two different types of silicone hydrogel lenses along with a specific cleaning solution.
What is being tested?
The study compares two types of multifocal contact lenses: investigational LID233309 (Serafilcon A) and Oasys Multifocal (Senofilcon A). It aims to assess their performance when worn daily by participants, using CLEAR CARE® Cleaning & Disinfecting Solution.
What are the potential side effects?
Potential side effects from wearing contact lenses may include eye discomfort, dryness, redness, blurred vision, tearing up or feeling like something's in your eye. The cleaning solution could cause eye irritation if not used properly.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Oasys MF, then LID233309Experimental Treatment3 Interventions
Senofilcon A multifocal contact lenses worn in Period 1, followed by serafilcon A multifocal contact lenses worn in Period 2, as randomized. The study lenses will be worn bilaterally (in both eyes) during waking hours for at least 10 hours per day, each wear period \[14 days (-0/+2)\]. Study lenses will be removed daily for cleaning and disinfection with CLEAR CARE.
