About this trial
This is an interventional treatment trial for Dry Eye focused on measuring Post LASIK dry eye, Pre LASIK dry eye, Hypromellose
Eligibility Criteria
Inclusion Criteria:
- Age 21 - 35
- Both sexes
- Seeking LASIK surgery at the Refractive Surgery Centre
- Meeting all established criteria for appropriateness for LASIK established by the treating center
Exclusion Criteria:
- Any corneal pathology including scars, prior herpes keratitis, prior corneal transplant
- Any immuno-compromised state including cancer, HIV infection, Hepatitis B or C, or diabetes mellitus
- Requirement for any eye-drops for any reason (eg, dry eye or conjunctivitis) within 3 months from time of enrollment
- Anticipated refusal or inability to undergo planned post-operative visits or assessment
- Failure to meet all established criteria for appropriateness for LASIK

Outcomes
Primary Outcome Measures
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.
Secondary Outcome Measures
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.
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.

Brief Summary
This study is designed to assess the tolerability and comfort of peri-operative 0.3% hypromellose eye drops in LASIK surgery patients and to assess whether pre-operative 0.3% hypromellose eye drops add to post-operative comfort in LASIK surgery patients compared to control (no pre-operative lubricant).
