Air Optix Extended Wear Contact Lenses

Alcon Research505 enrolled

Overview

The purpose of this Post-Market Clinical Follow-Up (PMCF) study is to assess long term performance and safety of Air Optix Aqua Sphere, Air Optix plus HydraGlyde Sphere, and Air Optix plus HydraGlyde Toric soft contact lenses in a real-world setting when worn as extended (overnight) wear.

This is a non-interventional/observational study designed as a retrospective chart review. Study sites will identify charts within their existing databases in a fair and consistent manner, e.g., reviewing all eligible charts in reverse chronological order by year of baseline visit. Subjects/charts meeting the eligibility criteria will be enrolled in the study. The data collection period is defined as any approximately 1-year to 3-year timeframe since the respective lens brand was prescribed.

Inclusion Criteria: * Manifest refraction cylinder less than or equal to 0.75 diopter (D) in each eye at baseline (sphere wearers only); * Best corrected visual acuity (BCVA) of 20/25 Snellen or better in each eye at baseline; * Must have worn or be wearing Air Optix Aqua Sphere, Air Optix plus HydraGlyde Sphere, Air Optix plus HydraGlyde Toric, Biofinity Sphere or Biofinity Toric for at least 3 years in an extended wear modality, as determined by the Investigator; * Other protocol-defined inclusion criteria may apply. Exclusion Criteria: * Any recurrent history or active anterior segment infection, inflammation or abnormality contraindicating regular contact lens wear at baseline; * Use of systemic or ocular medications contraindicating regular contact lens wear at baseline and/or during the period of the retrospective chart collection; * Slit lamp findings, including signs of pathological dry eye, that would contraindicate regular contact lens wear; * Other protocol-defined exclusion criteria may apply.

Outcomes

Primary Outcomes

Distance visual acuity (VA) with study lenses at Year 1

The subject's chart will be reviewed for distance visual acuity at Year 1, defined as a visit which occurred 1 year (-2/+4 months) since baseline during which period the subject was wearing either the study or comparator lenses and a contact lens examination was performed. The Baseline visit is defined as the first office visit where an eye care practitioner provided an in-person office biomicroscopy exam to the patient before or during which a contact lens prescription for the study or comparator contact lens (lotrafilcon B or comfilcon A) was released.

Time frame: Year 1

Distance visual acuity (VA) with study lenses at Year 3

The subject's chart will be reviewed for distance visual acuity at Year 3, defined as a visit which occurred 3 years (-2/+8 months) since baseline during which period the subject was wearing the protocol required contact lenses and a contact lens examination was performed.

Time frame: Year 3

Incidence of corneal infiltrative events

The subject's chart will be reviewed for incidences of corneal infiltrative events occurring after the baseline exam.

Time frame: Up to Year 3

Incidence of microbial keratitis

The subject's chart will be reviewed for incidences of microbial keratitis occurring after the baseline exam.

Time frame: Up to Year 3
