No intervention

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Patients With a Presence of Matrix Metalloproteinase-9 (MMP-9) in the Study Eye
Time Frame: 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

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Suspected of Having Dry Eye With Elevated MMP-9
Time Frame: 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
Time Frame: 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
Time Frame: 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.
Up to 60 days prior to cataract surgery
Percentage of Participants With Elevated MMP-9 With Dry Eye Symptoms Without Any Signs
Time Frame: 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
Time Frame: 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
Time Frame: 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
Time Frame: 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
Time Frame: 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
Time Frame: 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
Time Frame: 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).
Up to 60 Days Prior to Surgery
