NCT ID: NCT05239494 Completed - Dry Eye Clinical Trials

Dailies Total 1 Sphere Contact Lenses

Start date: May 23, 2022
Phase: N/A
Study type: Interventional

CL discomfort is a complex phenomenon that has been defined by the Tear Film and Ocular Surface Society in their seminal report on contact lens (CL) discomfort as a condition that results in "episodic or persistent adverse ocular sensation related to lens wear, either with or without visual disturbance resulting from reduced compatibility between the CL and the environment, which can lead to decreased wearing time and discontinuation of CL wear." A recent review by Pucker and Tichenor found that CL discomfort was the top reason for established CL wears to cease wearing CLs. This same review alarmingly found that the frequency of CL dropout was about 20% across the many studies aimed at evaluating this condition, which is surprising given the introduction of better soft CL materials and daily disposable CLs over the past 20 plus years. Dailies Total1 (DT1), which is a relatively new daily disposable CL, is a commonly used trouble shooting CL for patients who have failed with other CLs because DT1 utilizes advanced material technology that is specifically aimed at improving CL comfort. While DT1 is commonly used in these struggling patients, the literature currently lacks a targeted study aimed at understanding the frequency of successfully refitting CL dropouts into this advanced CL. Thus, the purpose of this study is to determine the frequency that past CL wearers who failed because of dryness or CL discomfort who can comfortable wear DT1.

NCT ID: NCT05183022 Completed - Dry Eye Clinical Trials

Total30 Sphere Contact Lenses

Start date: January 3, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to map comfort over the full wear day in established, asymptomatic, soft CL wearers who are refit in Total30 Sphere CLs.

NCT ID: NCT04806763 Completed - Children, Only Clinical Trials

Myopia Control With Orthokeratology Contact Lenses in Spain

MCOS
Start date: March 1, 2007
Phase: N/A
Study type: Interventional

The purpose of this prospective study is to assess the efficacy, safety and patient-reported outcomes of the Menicon Z Night orthokeratolgy contact lens for reducing myopia progression in children.

NCT ID: NCT04663529 Completed - Dry Eye Clinical Trials

Correlation Study of Corneal Nerve Changes and Dry Eye in Contact Lens Wearers

Start date: October 1, 2020
Phase:
Study type: Observational

This study aims to analyze the changes of corneal nerve morphology and function in contact lens-related dry eye(CLADE) patients and further discuss the role of corneal nerve in the genesis and development of CLADE.

NCT ID: NCT03848221 Completed - Dry Eye Clinical Trials

Direct Application of Systane Complete to Contact Lenses

Start date: May 28, 2019
Phase: Phase 4
Study type: Interventional

A common first line treatment for patients with dryness symptoms or contact lens discomfort is the application of artificial tears or rewetting drops, respectively. Rewetting drops are specifically formulated for use with contact lenses while artificial tears are indicated for dry eye. Modern rewetting drops and artificial tears have similar formulations with similar preservatives, preservatives that have been shown to be compatible with contact lenses. While rewetting drops and artificial tears are regulated under different U.S. Food & Drug Administration policies, artificial tears are not specifically indicated for direct use with contact lenses. Nevertheless, clinicians commonly prescribe artificial tears to contact lens wearers likely because newer formulations of artificial tear have the potential to outperform available rewetting drops. The safety and efficacy of using artificial tears with contact lenses for the treatment of discomfort is supported by Caffery and Josephson and Ozkan and Papas who found that artificial tears significantly reduces dryness symptoms in contact lens wearers. Thus, the purpose of this study is to test the safety of directly applying a new artificial tear, Systane Complete, to the contact lens wearing eye and its ability to alleviate symptoms while wearing contact lenses during the day.

NCT ID: NCT03566680 Completed - Dry Eye Clinical Trials

Treating Contact Lens Discomfort With Orthokeratology

Start date: August 7, 2018
Phase: N/A
Study type: Interventional

The primary aim of this study is to understand if orthokeratology can be used to improve contact lens comfort and the secondary aim is understand patient adaptation to orthokeratology.
