About this study

Official title: Efficacy, Tolerability and Comfort of 0.3% Hypromellose Eyedrops in the Pre- and Post-Operative Treatment of Patients Undergoing LASIK Surgery

Conditions: Dry Eye
Being tested: Pre-LASIK 0.3% hypromellose, Post-LASIK 0.3% hypromellose
Keywords: Post LASIK dry eye, Pre LASIK dry eye, Hypromellose
Medical subject headings: Dry Eye Syndromes

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Pre-LASIK 0.3% hypromelloseDrug
Patients self-administered GenTeal eye drops qid (quarter in die, 4 times a day) starting 5 days prior to LASIK surgery and continuing through 1 month after LASIK surgery.
Post-LASIK 0.3% hypromelloseDrug
Patients self-administered GenTeal eye drops qid (quarter in die, 4 times a day) starting on the day of LASIK surgery and continuing through 1 month after surgery.

Study groups in NCT00909324

Pre-LASIK 0.3% hypromellose	Experimental	Not described Receives: Drug: Pre-LASIK 0.3% hypromellose
Post-LASIK 0.3% hypromellose	Active comparator	Not described Receives: Drug: Post-LASIK 0.3% hypromellose

What is being measured

The primary outcome is the main question the study is designed to answer.

Ocular Comfort Level From Baseline to End of Study
Patients rated their ocular comfort on a scale of 0 to 10 on the following parameters: Burning sensation, foreign body sensation, itching, watering of eyes, dryness of eyes, and photophobia. A higher score indicated greater discomfort. A negative change score indicated improvement.
Measured: Baseline (Pre-LASIK surgery), Day 1, Day 7 and Day 30 post-LASIK surgery

Secondary outcomes (2)

Tear Breakup Time From Baseline to End of Study
The time required for dry spots to appear on the corneal surface after blinking. Sodium fluorescein dye is added to the eye and the tear film is observed under a slit lamp while the patient avoids blinking until tiny dry spots develop. The longer it takes, the more stable the tear film. A short tear breakup time is a sign of a poor tear film. Generally, >10 seconds is thought to be normal, 5 to 10 seconds marginal, and <5 seconds low (with high likelihood of dry eye symptoms), ie, a shorter time indicates greater eye dryness. A positive change score indicates improvement.
Measured: Baseline (Pre-LASIK surgery), Day 1, Day 7 and Day 30 post-LASIK surgery
Results of Schirmer's Test From Baseline to End of Study
Schirmer's test determines tear production, and whether the eye produces enough tears to keep it moist. A small strip of filter paper is inserted inside the lower eyelid of each eye and the eyes are closed for 5 minutes. The paper is then removed and the length of paper that is moist is measured. A young person normally moistens 15 mm of the paper. The shorter the length of moist paper, the dryer the eyes. A positive change score indicates improvement.
Measured: Baseline (Pre-LASIK surgery), Day 1, Day 7 and Day 30 post-LASIK surgery

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Mar 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Ocular Comfort Level From Baseline to End of Study (time frame: Baseline (Pre-LASIK surgery), Day 1, Day 7 and Day 30 post-LASIK surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00909324.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2020; AzTrials last refreshed its copy on 8 Nov 2026.
