Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Percentage of Patients With a Presence of Matrix Metalloproteinase-9 (MMP-9) in the Study Eye
Lasso di tempo: Up to 60 Days Prior to Surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
|
Up to 60 Days Prior to Surgery
|
Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Percentage of Participants Suspected of Having Dry Eye With Elevated MMP-9
Lasso di tempo: Up to 60 days prior to cataract surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Suspected of having dry eye was defined as a response of "Yes" to the Investigator Dry Eye History question.
|
Up to 60 days prior to cataract surgery
|
Percentage of Participants With Elevated MMP-9 Without Prior Diagnosis or Physician Recommended Intervention
Lasso di tempo: Up to 60 days prior to cataract surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Participants without a prior diagnosis of keratoconjunctivitis sicca, dry eye or tear film insufficiency or physician recommended use of topical cyclosporine, artificial tears or punctal plugs are included in the analysis.
|
Up to 60 days prior to cataract surgery
|
Percentage of Participants With Elevated MMP-9 With Dry Eye Symptoms Without Conjunctival or Corneal Staining
Lasso di tempo: Up to 60 days prior to cataract surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Dry eye symptoms were measured by a score of at least ≥ 2 using the Subject Evaluation of Symptoms of Dryness (SESoD) questionnaire without conjunctival or corneal staining.
The SESoD assesses dry eye using a 5-point scale where 0= no dryness to 4= severe dryness.
Conjunctival and Corneal Staining were evaluated as part of the slit lamp biomicroscopy examination.
Eye structures and surfaces were assessed for dry eye signs using a 5-point scale where: 0=none, 0.5=trace, 1=mild, 2=moderate and 3=severe.
Higher values represent a worse outcome.

Percentage of Participants With Elevated MMP-9 With Dry Eye Symptoms Without Any Signs
Lasso di tempo: Up to 60 days prior to cataract surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Dry eye symptoms were measured by a score of at least ≥ 2 using the SESoD questionnaire without any signs.
The SESoD assesses dry eye using a 5-point scale where 0= no dryness to 4= severe dryness.
Signs included conjunctival or corneal staining, Schirmer's score ≤ 7mm, or Tear Film Break-up Time [TFBUT] ≤ 10 seconds.
|
Up to 60 days prior to cataract surgery
|
Percentage of Participants With Elevated MMP-9 With at Least One Dry Eye Sign Without Dry Eye Symptoms
Lasso di tempo: Up to 60 days prior to cataract surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Dry Eye Signs included conjunctival or corneal staining, Schirmer's score ≤ 7 mm, or Tear Film Break-up Time [TFBUT] ≤ 10 seconds without Dry eye symptoms measured by a score of at least ≤ 1 using the SESoD questionnaire.
The SESoD assessed dry eye using a 5-point scale where 0= no dryness to 4= severe dryness.

Up to 60 days prior to cataract surgery
|
Percentage of Participants With Elevated MMP-9 With at Least One Dry Eye Sign and Dry Eye Symptoms
Lasso di tempo: Up to 60 days prior to cataract surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Dry Eye Signs included conjunctival or corneal staining, Schirmer's score ≤ 7mm, or Tear Film Break-up Time [TFBUT] ≤ 10 seconds with Dry eye symptoms measured by a score of at least ≥ 2 using the SESoD questionnaire.
The SESoD assessed dry eye using a 5-point scale where 0= no dryness to 4= severe dryness.
|
Up to 60 days prior to cataract surgery
|
Percentage of Participants With Elevated MMP-9 Who Routinely Use Artificial Tears
Lasso di tempo: Up to 60 Days Prior to Surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Artificial Tear usage was assessed by the investigator.
|
Up to 60 Days Prior to Surgery
|
Percentage of Participants With Elevated MMP-9 With Punctal Plugs
Lasso di tempo: Up to 60 Days Prior to Surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
A history of punctual plug usage was assessed by the investigator.
|
Up to 60 Days Prior to Surgery
|
Percentage of Participants With Elevated MMP-9 With Corneal Staining Grade ≥ 1 and ≥ 2
Lasso di tempo: Up to 60 Days Prior to Surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
Corneal Staining was evaluated as part of the slit lamp biomicroscopy examination.
Eye structures and surfaces were assessed for signs of dry eye using a 5-point scale where: 0=none, 0.5=trace, 1=mild, 2=moderate and 3=severe.
Higher values represent a worse outcome.
|
Up to 60 Days Prior to Surgery
|
Percentage of Participants With Elevated MMP-9 and an Ocular Surface Disease Index® (OSDI®) > 12, > 22 and ≥ 32
Lasso di tempo: Up to 60 Days Prior to Surgery
|
Tear film was collected and a diagnostic test was used to determine the presence of MMP-9 in the study eye.
The OSDI consists of 12 questions to assess visual function, ocular symptoms and environmental triggers related to dry eye.
Each of the 12 questions is assessed using a 5-point scale (0=none of the time to 4=all of the time) which is converted to a total score between 0-100.
OSDI total scores of 0-12=normal (best), 13-22= mild ocular surface disease, 23-32 =moderate ocular surface disease, and 33-100=severe ocular surface disease (worst).
